If on, the voltage will have a bit of bigger area of which it can operate. RAM should be at its default SPD settings as well. Once your computer starts to crash during boot or during the benchmarks, you will need to try 1 of 3 different options. In no time, you should be able to go from 0% – 29% using your stock cooler and thermal paste. Glad to see this made it out. As a rule of thumb you should keep your HTT between 1200 – 2200 MHz when overclocking. For now, the default timings of your RAM should prove to be the best for overclocking. This guide will use some basic terms that you may not be familiar with. AW: phenom II x4 955 übertakten Ich hab für dich mal die Screenshots von meinem damaligen 9 6 5er rausgesucht, vielleicht kannst du dich zumindest etwas an den Settings orientieren. After the rather disappointing Phenom was on the market for a year, the Phenom II brought AMD out of a huge hole as although the Phenom II did not compete on par with Intel in the benchmarking world, it did bring to the market a low cost CPU that was just as good if not better when it came to gaming. For my first example I will use the Phenom II 810. This same process will work as well with the HTT. 108. The overclocking ability of the Phenom II is directly proportional to that of its core temperature. Hallo, ich wollte heute meinen Phenom II X4 955 auf 3.6 GHz übertakten, jedoch bekomme ich Bluescreen, wenn ich z.B. Now you can move on to seeing how far you can push your CPU. Wie kann ich diesen übertakten, bzw. Each timing works with a corresponding DRAM Frequency. It has been a very long road with this guide. Even though it is a lot better than its ancestors, it still has a long way to go. You can push the CPU-NB voltage to a max of 1.35V. The second section is “Overclocking with Black Edition”. Thuban wants everything to be happy, and requires harmony between all four areas. It often creates a much more stable environment if you do this. They will go in order 800, 1066, 1333, and 1600. Most of the time, you will be required to have a pretty high voltage on the CPU-NB with a low frequency in order to keep your CPU stable. Bus-Geschwindigkeit: 667 MHz Speicher-Controller, One 2000 MHz 16 Bit Hypertransport Link (4 GT/s). It was genuinely very helpful. Most of you that have been around the forums know about “Dolk’s guide” if you have ever wandered into the AMD section. The speed of your CPU-NB is the max speed of your HTT. Table 2 is only a reference and may not apply to your RAM. I do not suggest using it for 24/7 overclocking though. Just make sure to work inside the limits of your computer and the limits I have mentioned in this guide. Deneb was the first Phenom II core released. In practice it does not work 100%. There is no easy way of doing it, unless you do not want to see the best gain out of your CPU. The Deneb is much hungrier when it comes to voltages and it does not cope well when the core temperature is anywhere near 55 C. The Thuban is much more gentler, and allows higher clocked cores without the need for high voltages. There are two parts to the memory settings: frequency and timings. AMD Phenom II X4 940 Black Edition. Ich ahbe den AMD Phenom II X4 955 BEm prozessor auf einem gigabyte GA-MA-790XT-UD4P Motherbpoard. I would suggest that you do not touch the other settings not covered here unless you know what they do. First thing is first, for all CPUs: find your walls. This tends to be a lot of fun for most people. One important thing to also note and always remember is that the HTT speed can never go higher than the CPU-NB speed. AMD Phenom II X4 810. Here is where we start finding your maximum CPU frequency speed, along with supported speeds with HTT and CPU-NB. First is “The Old Fashioners”. You have to watch everything: RAM, HTT, CPU-NB, and CPU. No matter what you do, you will not be able to get around this wall. Thuban was not a redesign of the CPU, but tapped into the (as yet un-released) power of the Deneb. With HT 3.0 technology the AMD Phenom II X4 955 Quad-Core processor enjoys 3200MHz system bus speeds. The RAM ratio will be shown in one of two ways depending on your motherboard maker. The recommended voltage for 24/7 usage is 1.40-1.45 v. If you run into a situation in which wPrime throws an error, this is considered a theoretical max as well. This method only works with Phenom II BE chips though. Then, when you switch from automatic to manual mode, you do not start off too low or too high with your overclocking. DRAM Frequency = [ (FSB Frequency * DRAM Ratio) / FSB Ratio ] * 2. Voltage may be added to the CPU-NB to help. $45.90: Zum Angebot: AMD Phenom II X4 955 3.20 GHz Quad-Core... AMD Phenom II X4 955 3.20 GHz Quad-Core Processor HDX955WFK4DGM Socket AM3 PGA-938 95W There are several different types of timings you can modify but there are only six that you will want to work with. Sometimes it takes time to find the sweet spot for your CPU. Yes that is correct, the CPU-NB also creates heat on the die. The idea behind the formula is a rough estimate of what you should be at with ‘X’ CPU Frequency. This will tell you how far you can go, and at what temperature you may be running at. I have constructed a table outlining the settings at which your CPU-NB should be with ‘X’ CPU Speed. In order to find your speed without my table, you can use my formula: CPU-NB Frequency (+/-200) = (CPU-Frequency * 2 ) / 3.15. Once it hits a maximum of 60 °C LOAD, you MUST STOP! As you continue to increase your CPU speed, make sure to watch the CPU temperature. With each bump, make sure to keep your CPU speed as close to its stock speed. Using one of the ratios and a simple equation, you can determine the speed at which your RAM is running. Save my name, email, and website in this browser for the next time I comment. Just know that modifying the FSB will also affect things other than the CPU core speed. These voltages were based off using a 940 using default settings. Start pushing the FSB by a factor of 10, and then by a factor of 5. NOTE: When configuring the ratio of your RAM, not all BIOS’s will  be the same. For this next example I will take a Phenom II 940 BE CPU and overclock it. For each successful boot, make sure to run some sort of benchmark test or stress test (Check the section titled: Benchmarking and Stress testing tools for more information). The sections are broken down as follows: The first thing to learn is the basics of your RAM settings. AMD Phenom II X4 955 vs Intel Celeron G530: 4. Cracking article! Now that  you have seen actual data charts you can criticize my theorem, do not worry I already do it myself. But the general idea is that the FSB of your CPU will determine the speed of your RAM. AW: Phenom II x4 955 BE Übertakten? This can end up causing BSODs (Blue Screen of Death) or Freeze ups. Deneb allows you to effectively ignore the CPU-NB or the HTT. If you go above this, you may want to lower the HTT back down between 2200 – 2400 MHz. A complete guide to the AMD Phenom II family. I mentioned in the Memory section that the Memory has limitations due to the CPU-NB. For the first wall, let us find your max core wall. Your RAM timings represent the number of cycles it takes for information to be processed. Table 1 shows an example of some common ratios. A good place to confirm stock specifications is AMD’s desktop processor product list. In most cases, you will not need to exceed 2.4v on DDR2, and no more than 2.1v on DDR3. B CPU: AMD Phenom X4 II 955BE @ 3,62 Ghz Mainboard: Gigabyte GA970D3 RAM:... Dieses Thema im Forum "Prozessoren" wurde erstellt von Go4Nvidia, 20. The six timings that you will tweak are: Cas Latency (CL), RAS# to CAS# Delay (tRCD), RAS# Precharge (tRP), Cycle Time (tRAS), Bank Cycle Time (tRC), and Command Rate (CR). Intel Core 2 Quad Q9450. The main one being the Heat Wall (read more about that in my Heat Wall section). Thuban brought to the market more cores and a much more powerful internal memory controller (IMC). Who knows, you may need to actually work with the FSB. I personally love doing this in my spare time. Please make sure to look up the default values for your specific CPU at the link provided. 118. Play around with it, and see how it affects your system in both stability and speed. :beer: :beer: :beer: The "Dolk's guide" link almost doesn't work. If your goal is to make your CPU stable, you NEED to lower the settings to have the CPU LOAD temp at a max of 55 °C. Remember the BE CPUs have an unlocked multiplier so increasing the FSB to get a higher clocked CPU is not necessary. Bei AMD bieten sich vor allem die Phenom und Phenom II Prozessoren auf Basis von Sockel AM2+ oder AM3-Mainboards zum Übertakten an. When the North Bridge (NB) of a Phenom II is discussed, it is safe to assume that they are talking about the CPU-NB. Going above and beyond however, things will start to become more complicated, especially as you try to factor in higher benchmark scores with your overclocks. The Third section “Crash *Computer Explosions*” has two main sections. This section is intended for those that do not have a B.E. Wie wird das System schneller? Incredible article!!! In 90% of cases this is true, but the other 10% of people have something called a BE or Black Edition CPU. 41,4. Same goes with your HT, CPU-NB Frequency, and the RAM timings, and ratio. If all has gone well, you should have found a high overclock that is technically your max with the variables set by the theoretical max found by the AOD testing. Depending on whether you want a stable computer, or just benchmark it before it dies, you need the tools to do it. The second part contains the CPU-NB, and HTT. Listed below are the typical stock voltages of a Phenom II. It is all about optimization these days; getting the fastest out of your hardware, down to the last clock of RAM. For this you will need to get AMD OverDrive (AOD). Diskutiere und helfe bei AMD Phenom II X4 940 übertakten im Bereich Prozessoren im SysProfile Forum bei einer Lösung; Hallo, ich würde gerne meinen AMD Phenom II X4 940 BE übertakten. Read More, G.SKILL demonstrates that DDR4 memory is capable of reaching a higher tier of extreme speed than ever before, at up to DDR4-5000MHz with 8GB and 16GB memory modules, as well as DDR4-4400 with high-capacity 32GB modules. AMD hat aus Kostengründen nicht auf LGA1366 Ebene geklotzt. These CPUs are fun to own, and are a whole other beast when it comes to Extreme Overclocking and cooling. You can try to increase your RAM to a higher ratio, and using what you learned about your RAM back in the RAM section, increase the timings to work with that ratio. Mostly because it is usually the culprit of bad overclocks. I remember reading this when the 720's first came out. A good place to start is confirming where each setting is located before beginning to overclock. AW: Welchen Kühler für AMD Phenom II X4 955 BE Das selbe hier, Scythe Mugen 2, bietet eins der besten P/L-Verhältnisse Mein 940er klettert auf 55°C bei 3,7 Ghz, unter nem Noctua NH-U12P. Intel CPUs have historically struggled with cold temperatures, as the CPU would start to become unstable upon hitting a certain temperature. These numbers represent the ratio you wish to use. Intel Core i7 920. If you do have a Black Edition CPU, it is still wise to read through this section. Der Multiplikator ist ja standardmäßig auf x4.0 eingestellt. AMD Phenom II X4 940 Black Edition. Your email address will not be published. Changing the CPU-NB frequency to lower or higher settings may help stabilize the OC. Diskutiere und helfe bei AMD Phenom X4 II 955 BE + Gigabyte GA970D3 im Bereich Prozessoren im SysProfile Forum bei einer Lösung; Hallo Leute, habe folgendes System: Kühler: Scythe Mugen 2 Rev. The CPU-NB is the section of the CPU that controls the L3 Cache, IMC and the HTT. Note, that “The Heat Wall” will also appear in places you never would expect. The 940 BE was the flagship CPU, in some cases reaching 4.0 GHz with water cooling and benchmarking with 3D Mark06 at 6.5 GHz. What you should get from this section is an understanding of the importance of the CPU-NB and how it affects your overclocking process. With these “Theoretical Maxes”, you can now find the max stable overclock with your defined CPU voltage. 36,2. After a long time of re-writing and waiting on AMD to push out all of their CPUs, I want to share with the community the final guide for the Phenom II CPUs. AMD Phenom II X4 955 Black Edition. The memory frequency can be changed by changing the the FSB frequency and/or ratio. This is a great tool to overclock your CPU in the OS environment. Most of the time, this will work. With  the speeds increasing for memory, it is normal that latency increases for stability purposes. This can be turned on or off. To all those that were expecting a section called “The Heat Wall” here it is in simple form. With these new buffs the Phenom II got a new boost in the CPU market. If that does not work then you have to bring things back down, and figure out how to create a faster overclock at slower speeds. If something goes wrong here is a common list of the error, explanation, and resolution as how to fix it. The CPU-NB is probably the most complicated part of the Phenom II. 215 * 14 ˜ 3000 MHz Core Speed. If we include every cumbersome detail directly, the guide would be back up to the 50 pages it started at - an avalanche of information can hurt more than it helps. I grabbed the stock NBv from the Thermal, and Voltage white papers that AMD released. Also note that the CPU-NB voltage should never exceed 1.35 v in any way. Read More. CPU-Z will be used as an accurate tool to show what speed your CPU is at, and what Voltage it is at as AOD is not 100% reliable with this. AMD Phenom II X4 955 vs Intel Pentium 2129Y 97. Since we have seen the tock, we now expect even further refinement. Before We Overclock details the 3 major subsystems which are key to overclocking this family of processors and is helpful for understanding how things work together. You guys have it the easiest, but this time around I’m not going to just tell you what you need to do in order to achieve a high overclock. If this is not the case, follow BSOD instructions. Übertakten eines AMD Phenom II X6 1090T: SKy89: Overclocking - Übertakten: 7: 18.06.2015 20:12: Phenom II X6 1055T Übertakten auf 4 Ghz: Chabrol: Overclocking - Übertakten: 4: 01.07.2013 07:31 [News] MSI Unlock CPU Core: Aus Phenom II X4 wird Phenom II X6 geht auch mit MSI: TweakPC Newsbot: News: 1: 19.04.2010 19:30 I will use the 940BE in these two examples. Use for 12+ hours to learn if settings are fully stable. In here everything is still connected by the FSB of the CPU, and each part has its own speed. AMD VirtualizationVirtualization on desktop computers allows a single PC to act like multiple virtual machines. So let us look at how the FSB and Multiplier can be used to overclock the CPU. As mentioned before, the CPU-NB and the HTT have different multipliers: please remember this. Here are the most common terms that I will be referring to. Unser Test prüft, ob die AM3-CPU auch effizient rechnet. The only way to get around it is if you lower the temperature even further. Third side note, turn off Turbo Mode. Repeat wPrime test, then repeat CPU speed increase until either one of two things happen; either the system becomes unstable due to lack of voltage, or the CPU will get too hot. In this section I will teach you overclocking basics for the Phenom II. So, the CPU-NB and HTT have their own speeds, and they work the same way as the CPU cores. Nach unserem AMD Phenom II X4 955 BE Testbericht konnten wir sehen, dass es sich hier um eine sehr interessante CPU handelt. For example, if your system is running at 14C load temp, you may only see a maximum OC of 4.2 GHz or something similar. Loosening (raising) RAM timings may also help as well or lower the Frequency of the RAM. You are going to need Prime95 or a similar tool for this next part. Soon after, the 720 and 500 came out onto the field, bringing the possibility of core unlocking with them. The reason behind this is due to the IMC limitations. 4,1 GHz konnte man noch Cinebench rennen lassen: As a second side note, some of the newer boards that use the 8-series chips now have a feature called LLC or Load-Line Calibration. The voltage of your RAM will need to be researched. You should know how high you will want to push the voltage, but a reasonable guideline is to not go beyond 1.55V on air cooling. For most people, they want to use the overclock settings they obtained 24/7. The ROG STRIX RTX 2060 OC is currently priced at $399 which is only $50 over the lowest priced model over at Newegg.com, let’s take a dive into this card and see what that $50 is going to get us. Now that you know how to determine the speed of your RAM, you can now set the timings of your RAM. The FSB always has a stock frequency of 200 MHz. Prerequisites explain basic details to understand the guide. Run wPrime 32M. I know the 7xx IGP chipsets (not sure on 785) are all 1.3v. Use it for 10 mins to learn if it is somewhat stable. As you can see, it’s just as simple as the CPU core speed calculation. The guide has had many re-writes to update details or add more in-depth information about CPUs in general. AMD Phenom II x4 955 Be übertakten? The core speed is then determined by the FSB multiplied by the CPU multiplier. The third option that you may want to try is messing with your RAM. You finally get to overclock your CPU [rejoice]. Make sure to try a variety of different settings until you feel comfortable. As always the lord of all walls is the heat wall. Intel Core 2 Duo E7200. AMD Phenom II X4 965 Black Edition Box, Sockel AM3 Übertakten Hi, wie der Titel schon sagt möchte ich gerne meinen prozessor etwas übertatkten. Good stuff - happy to finally see it on the Front Page! You will understand this once you encounter “The Heat Wall” for the first time. Let us take a step back and look at what you have done so far. Before we begin, you must understand that there will be a limit to the CPU, and you will have to accept it. The HTT and a couple of other things are what make up the CPU-NB but to make things more straightforward, I will talk as if the CPU-NB and the HTT are two different entities. I now see what you are talking about with the forum link not working. Hey leute, ich überlege mir bald einen neuen pc zu bauen, mit amd phenom ii x4 955. allerdings würde ich diesen gerne uach höher übertakten. Simply put, they both have their own multiplier and they are directly affected by the FSB. Intel Celeron N2815 vs AMD Phenom II X4 955: 2. You guys really reduced it from ∞ to 3? There are many benefits to this and they will be discussed in detail later in this section. The reason behind this is bad RAM or OCed RAM, or can be caused by instable CPU-NB. This seldom works, but has proven to work in some situations. Only a few people have ever used this very expensive substance, but the results have proven the utility of liquid helium. And finally, the guide wraps up with several subsections to assist you if you run into trouble. Mit dem AMD Phenom II X4 945 bekommen Sie einen 3-GHz-Quad-Core für günstige 150 Euro. If you are anywhere near this sweet spot, OC settings will start to become unstable. Once it seems that your System will not crash, open up wPrime v1.55 and set the thread count to 6 under advanced settings. You will increase the FSB by a factor of 10 then by a factor of 5 after that. Overclock using Multiplier: Lower your FSB back to 200 stock speed, and bring your CPU multi back up to its stock value. 3DMark 03, 06, and Vantage (Only for Windows Vista and 7). Voltage added to the CPU or CPU-NB can sometimes fix this problem. Lower numbers are better when talking about latencies. Otherwise, maybe you’ve heard of it from the references across other enthusiast forums who link back to Overclockers.com for the instructions. Part 2 covers the CPU-NB, and HTT but the main focus is the CPU-NB. It tends to work better. AMD Phenom II X4 945 übertakten. The first Phenom II was the 940 BE which was followed closely by the 920. While this will work for the majority of the time, it does not work all the time. GTA IV spiele. AMD Phenom II X3 720 Black Edition. Your RAM has a direct link to your CPU, there is no chip in between – the CPU has an IMC (integrated memory controller). The guide will work with all Deneb, Heka, Callisto, and Thuban CPUs. The Voltage issue is simple, increase voltage. This is a useless function that has no purpose for now. 45,2. AMD Phenom II X4 955 vs Intel Pentium G4560: 6. Normalerweise hab ich bei meinem Phenom einfach denn Multi angehoben und hab ihn so ein klein wenig Übertaktet. A lot of the time you will spend overclocking, using the FSB, will be trying to balance everything. If your CPU is too fast and your CPU-NB is too slow, you will create instability. Once your computer does not boot up any longer, this means you have found your FSB maximum speed. This does not mean you will be able to run 24/7 on these settings, it just shows that your CPU can handle an instance of intense benching which means there is hope (sometimes very small). This leads to less headroom with your CPU because the CPU-NB is now creating extra heat on the die. This was something never before seen from an AMD CPU. Thank you a lot for putting this together Dolk. If you push something too much, you will have to increase the voltage for that section of the CPU. With each successful wPrime 32M run, close that program, increase the CPU-Multi by one once more, and hit Apply. Lian-Li Announces UNI Fan SL140 and Strimer Plus Triple 8 Pin GPU Cable, Alphacool Releases Four New Eisblock Aurora GPX-N Coolers for 30-Series Graphics Cards, G.SKILL Announces ENKI Series AIO CPU Coolers, Alphacool Announces Eisblock Aurora Acryl GPX-A RX 6800(XT)/6900XT PowerColor Red Devil GPU Water Block, Phanteks Launches Glacier One All-In-One CPU Coolers, Corsair Launches Hydro-X Series XG7 GPU Water Blocks, Biostar Announces All New Radeon RX 6900 XT Graphics Card, Mushkin Launches New ALPHA Series Solid State Drives, G.SKILL Memory is The Most Used DDR4 For Breaking AMD Vermeer OC Records, XPG Launches Levante 360 All-in-One Liquid Cooler, We use cookies to ensure that our site performs its best for you. • Freeze Ups: This may be caused by overheating of the CPU or could be a precursor to BSOD. You will also need wPrime version 1.55 and the latest version of CPU-Z. The discussion of the Phenom II itself is separated into two parts: Part 1 covers the cores of the CPU. For now you have found theoretical maxes to your CPU. The Phenom II has a maximum temperature of 55C. This will serve as a very useful tool as you overclock your Phenom II. For beginners, I suggest that you read everything before acting. In essence it will come down to you playing around with your timings and testing them to find the best balance of both stability and speed. For example let us look at the 810 once more at stock speeds. This CPU has a stock speed of 2.8 GHz. Even though you have this powerful chip, you are still going to have walls that limit you as to how far you can go. 2 Stunden (ich weiß man sollte länger laufen lassen) laufen lassen und bekam keinen Fehler. Please do not even attempt to use Turbo Mode with an overclocked Thuban. This one is about 12 pages. As you can see with Table 3, these are the supposed frequencies of your CPU-NB at X CPU frequency. Given its base clock of 3.2 GHz, with appropriate cooling, this unlocked Black Edition chip can be overclocked to speeds in excess of 4 GHz. This will surely become one of the staple go-to guides for AMD overclocking. All of the settings that I refer to will be located in your motherboard BIOS. • BSODS: This is caused by memory instability. These can potentially even lower the voltage used when in idle mode. Please note now that you will probably not be operating on a daily basis at the speeds you will see. If you have that wall controlled, your overclocking experience will be a better experience. For those interested, more complete processor specifications can be referenced in the AMD Power and Thermal Data Sheet. With the Phenom II, a new era of overclocking was created. Read More, It seems like only yesterday we were reviewing the Skylake CPU, but it turns out that was nearly 17 months ago! It only cares about how much voltage you are giving it, and how cold it is. So for this next example I will increase the FSB to create a 3010 MHz CPU or a 3.01 GHz core speed. Your second option is to increase the CPU-NB frequency and/or voltage. The original Guide that I created is about 50 pages long. There is also the possibility of lowering the timings with your stock Ratio and voltage. On a side note, I did mention that the HTT will be used a lot more with Thuban. From what I have learned, the HTT likes to stay with the CPU-NB up to 2800 – 3000 MHz. The memory frequency is determined from a ratio, composed of the FSB (Front Side Bus) Frequency and the DRAM Frequency (Seen as FSB:DRAM). 200 * 15 = 3000 MHz Core Speed, Overclock using FSB: With this ‘Y’ voltage at ‘X’ speed, you have been able to see if it is stable under Prime95 with ‘C’ CPU-NB settings and ‘B’ HTT settings (where ‘C’ also includes CPU-NB voltage). Open up AOD; This tool is designed to do exactly what I am showing you. Shortly after the release of the Phenom IIs, it was discovered that they could still operate at a temperature below even that of liquid nitrogen (-196 C) . There you have it. In some cases you will find that 7-9-7-15-30, or something similar, will be the best for speed and stability. Now that you have found your FSB Maximum, you can now push the CPU to see how high of an overclock you can accomplish. The AMD Phenom II X4 955 is a quad-core processor based on the K10 micro-architecture. I find using the FSB to overclock the CPU a lot more fun and challenging than the newly fashioned unlocked multipliers. NOTE: Please be familiar with your motherboard BIOS. #3 Suchr, 23. AMD Phenom II X4 955 BE / ASRock 890FX Deluxe 5 (kein Multi ? Just to give an idea of how much was trimmed down. This will allow a sort of fluctuation with the CPUv and CPU-NBv. Actually I have Super Pi 1M, 3D Mark 06, PC Mark 05 and Geekbench charts as well showing that the 2800 MHz NB usually is top of the charts rather than the recommended speeds by my calculations. If you are having trouble with your overclocked CPU, instead of increasing the CPU-NB try to bring it down. AMD Phenom II X4 955 vs Intel Pentium D1508: 5. Of course, as you increase the CPU-NB frequency, you have to increase the CPU-NB voltage. Hilfe beim Thema Hardware Overclocking und Modifizierung. You may find that the highest CPU-NB frequency is not necessarily the fastest or the most stable. HowTo AMD Phenom X4 II 955 BE + Gigabyte GA970D3. So you put alink there for someone to have to type it in instead of a direct link?
