Haswell Overclocking Guide [With Statistics] - Page 285

post #2841 of 19540
I have the 4770k with the Asus z87 pro motherboard and something seems to be puzzling me. I'm stable in everything I do, games such as BF3, Skyrim, Crysis 3, and others, and even stable for hours on any cpu stability test without AVX. But as soon as I use that fpu setting to have avx instructions thrown at my cpu, it BSODs super fast. I know I won't utilize AVX instructions, but should I push voltages higher for stability under them?

I have it at 4.4ghz 1.255v with the cache ratio at 40 w/ 1.15v on the cache voltage using 2133 XMP ram

You will use avx instructions, just not in the way that linpack etc would. If you're stable in x264 benchmark 5.0.1 (will use avx2 instructions in a real world way) then you're fine IMO

Kinda up to you. It's a mental thing for me, I want my cpu to be able to do everything it was made for so I run 4.2 at the same voltage that would be stable at 4.4 just so I wont bsod in AVX.

From the chips I tried 313 and 307 were the worst. 312 was the best.

For instance I need 1,87 Vrin, 1,14 ring and 1,36 Vcore for 4,8 Ghz with uncore x39. What System do you use ?

Major advantage of Prime95 CustomFFT: you may stress certain voltages.
864K/1344K for VCore
720K for VTT = analog / digital I/O
768K for VCCSA / System Agent
448K for Input Voltage / VCCIN / VRIN (different names for different mobo brands)
512K/576K for Cache/VRing Voltage

This is interesting... how did you arrive at the different FFT sizes to test various voltages?
post #2850 of 19540
If you're interested, my L310B940 is ~1.22vcore for 4.5ghz ht on tightly tuned which gives full stability in avx1 (ibt and 27.9) as a side effect but i don't run avx2 stuff at such voltages because it would be suicide on mere high end air with fast RAM
