SajinDon't use adaptive voltage. Use a static fixed voltage. Make sure you disable vdroop if the setting is available.
SajinIf you're using a static fixed voltage it should stay at exactly what you set it to. Very odd that it increase to 1.45 or higher when loaded.
SentaphIt appears there are no LLC settings in the BIOS?
Sentaph Yeah, I'm not sure. It seems to stay pretty fixed until I throw those small FFTs at it. I've just talked to someone on a different forum running the same processor and MOBO and they ran into the same voltage jumps. It appears there are no LLC settings in the BIOS? That said, they were able to achieve 5.1ghz with only 1.287v so ultimately it would seem I simply lost the silicon lottery badly.
satchmo0016This is a problem I've complained several times and submitted tickets about. I don't know why EVGA ignores it. Vdroop "disable" will add something around 80mV when under a normal "full" load, non-AVX. When you have an AVX load, intel spec is to add more voltage, so it stacks that on top of EVGA's vdroop compensation and I've seen over 120mV added when under AVX loads. There are no other settings to effect load-line voltage control. EVGA's implementation of vdroop compensation is very dangerous because you can go from a very reasonable setting of vcore if you say, input 1.3V static, and under load see voltages way above 1.4V, which is getting to the point of degrading your chip. Also, this board pumps system agent and IO voltages to borderline unsafe levels too, when selecting XMP. They should be VCCSA=1.05-1.15 and VCCIO=0.95-1.05. If you select XMP EVGA board blasts them to 1.25V, again getting close to unsafe levels and may start degrading the IMC on your CPU. Make sure you set these manually, because you CANNOT trust the EVGA board to ever use appropriate "auto" settings. Source: I have a z370 FTW board.
satchmo0016They're most certainly not getting 5.1Ghz at actual vcore that low. The EVGA board adds a lot of voltage behind your back with vdroop - disabled, and even more on AVX loads. Check my comment above.
