Pushing max voltages
Pushing max voltages
So this is for an older build. I wanted to really push it before upgrading or switching things up.
My configuration: 6700k Msi z170 M9, with an open loop cooler at 480 rad.
Right now I manage to get the CPU stable at around 1.45v, with temps staying near 65°C.
I’m still having issues booting at 4.9 and keep seeing BSODs.
My settings are:
CPU current limit max 256, vcore=override
At 4.8 I set vcore to 1.45.
Tried pushing the GPU to 1.55 but still got BSOD.
I experimented with override+offset, using vcore 1.55 and an offset of .05.
That’s causing current limit throttling—I can’t exceed 256.
I’ve tried both turbo boost on and off, but speed step is disabled.
Temperatures are high enough, but voltage isn’t rising enough.
Am I hitting the limit? Have I reached the extreme point? Do I need a custom BIOS? Any other questions? xD
Hopefully I missed something and can finally reach that 5.0! =)
The first video covers everything clearly.
The second video explains the concept, but I’m still confused about how it relates to the bios.
His explanation suggests the video shouldn’t be changed?
He’s describing how to adjust an LLC, but I don’t understand the settings or the process.
My assumption is he thinks I might be overdoing it or spiking too much—could be the reason for the BSOD? I’ll keep researching about LLC.
Alright, I haven't really made any progress.
I feel like i know this a bit better now, but i still cannot reach a better overclock.
The lowest i was able to get a stable overclock at 4.8ghz was vcore override at 1.45 at 77c
The other settings i have tried adjusting are as follows:
turbo boost:
long duration 250
short duration 250
cpu limit 250
Vdroop
cpu load line cal= mode 1
cpu gt load line cal = mode 1
phase control= optimized
dram over 250 mv
dram under 250 mv
dram switching frequency = 500khz
When i tried going up to 4.9 i had the same result as before
Then I increased the dram over and under to 350 because Intel utility was showing current limit throttling
It booted but failed as soon as a ran a stress test. I'm fairly certain this is a vdroop issue i just don't see a lot of adjustment in the bios other then cranking up dram over/under.
What does this actually adjust? How can i know what is safe for my chip?
Make changes to the LLC in the bios. I have an Asus unit, likely under digi/vram. After adjusting, I managed to reduce temperatures and prevent sudden voltage spikes that could trigger a BSOD. On Asus systems, the voltage range is from 1 to 7, with 1 being the safest and 7 the most lenient. My board was set to auto mode at 5, which helps ensure the CPU voltage stays within safe limits about 90% of the time.
