Hi, I have decided I will instead get an 9900k.
9900KS are officially binned by Intel, their quality are generaly excellent.Īsus's ROG (not ROG STRIX) motherboard is able to predict your setting in AI Suite 3 (the max non avx stable, the max cache stable, and the max avx stable), and even the silicon quality (in percentage) Even in the 9700K vs 9900K case, a ultra rare good 9700K stable at all core 5.1 at 1.265V (pass small FTTS in Prime95 without thread lost), while a trash 9900K is not even able to achieve that. The setting really varys depending on the silicn quality of a CPU, which can varies greatly among a single model. When disable HT, the idle transistor however adds to the thermal area effectively. HyperThreading squeeze more potential from a physical core such capability only requires a moderate amount of transistor in addition, at least not as much as that die need to be noticeably larger. If hyperthreading is disabled, 9900K(S) is even cooler than 9700K at same freq, as they are made from better quality silicon in general, lower voltage is required to stable at a frequency. You will need the luck of getting a top 9% and top 1% silicon quality 9700K to acheive AVX stability at 5.0Ghz and 5.1Ghz. It will directly effect the frequency of ram and pci devices. Stop at 1.42V unless liquid nitrogen is involved.įor long daily use, i wont't let the CPU operate at the voltage more than 1.35V or at the setting that will boil the chip beyond 90 degree during non prime 95 stress test.ĭont even think about modifying the BCLK frequency if you are a beginner. If non of them fail at all, your CPU is very close to flawless. If less than 2 of the workers ( thread ) fail, your CPU is stable in most situation at this setting. Increase this voltage by a further 0.3, and run the small FTTS in Prime 95 for at least 20 min. In order to emulate the most brutal condition your CPU will face, you need to test whether it can handle the AVX in Prime 95. You can also try finding the min voltage that does not result in instant failure. Once you remark the min boot voltage for your goal frequency, increase it by 0.03V, run the Intel Processor Diagonostic Tool first, then run some moderate stress test in Intel Extreme Tuning Utility, FPU in Aida64 for at least 15 min to detect if it result to Blue screen of Death. I.g, my min boot voltage (4.7Ghz) is 1.20volt, i will start finding the min boot volt (5.0Ghz) at (1.20 / 4.7) *5.0 = 1.28 volt. Now, estimate the min voltage of your goal by the following: estimated voltage = ( min boot voltage / 4.7 Ghz) * Your Goal in Ghz, always round it up. Remark the minimum "boot" voltage for 4.7Ghz. If it cant boot from the beginning, increase it by 0.02 and fire another attempt.
#Mac pro 5.1 max memory windows
If windows is sucessfully booted, decrease the voltage by 0.01 until it cant boot. Usually i start with 1.22 V for a 9700K, lower for 9900K and even lower for 9900KS. ( Remove the limits, sync all mulitpiler to 47, manually override your core voltage), dont tune your RAM yet. The 9700K can turbo to all core 4.6Ghz at stock setting, first find the minimum voltage to boot it at all core 4.7Ghz, with 0 avx offset. I assum an average 9700K is able to achieve stability at 5.1Ghz non avx, 4.9 Ghz avx, using the normal distribution. So what if I have an average 9700k? How high can I overclock, and what should I usually set my volts to?Īccording to.
