Intel 6800k OC Voltage

[Phoenix864]

Hi all,

 

I'm very new to CPU overclocking and was wondering if I could get some advice regarding the voltage settings for my Intel 6800k (running on a Gigabyte X99 SLI MB). So far, I've set the Vcore to 1.33v, the multiplier to 43, the base clock to 100mhz, and enabled XMP on my RAM (Corsiar Vengeance 3000mhz). Everything else has been left on the defaults. These settings seem pretty stable - I've had no issues running OCCT for 1h, Intel Burn Test on maximum, and MemTest for a few hours - though I did get a kernel-power error 41 after running Prime95 on small FFTs for a few hours. Temps are generally in the low 70s when running Prime95, so I still have some thermal headroom. 

 

I've been hoping to push the chip to 4.4ghz, however, I've noticed a few oddities that have me hesitant to push the voltage further. I do not want to go over 1.4v on the Vcore - I thought by setting it to 1.33v in the BIOS I would still have headroom to work with. When in the BIOS, the Vcore reports as a steady 1.33v. However, while testing in Windows HWmonitor reports the Vcore jumping around much more. I've seen it as low as 1.320v and as high as 1.380, with it often remaining around 1.35v-ish, even with the Vcore set in BIOS to 1.33v. If HWmonitor is correct, I'm worried that if I put to Vcore to say, 1.35v, the actual voltage may spike over 1.4v. I'm wondering if this has something to do with LLC, adaptive voltage, or another setting I left as default - is there something in particular I should check?     

 

Another very weird thing I noticed is that my Uncore as default in the BIOS is reported as 2.8ghz. I tried changing it to the recommended core clock - 100mhz (so 4.2ghz), but then I couldn't even get past the BIOS loading screen. Not sure exactly what's going on here - am I missing something regarding why it's set to 2.8ghz?

 

Lastly, I've been wondering about setting up adaptive voltage - it would be nice if I could save some power and not push 1.3-some volts through the CPU constantly. Is there a good way to go about setting up adaptive voltage without jeopardizing overclock stability or risking the MB doing something stupid with voltage delivery? 

 

Thanks for any advice.

 

Here's a couple of screenshots of HWmonitor after running Prime95 for a bit and a few photos of the BIOS settings. Update: bumped Vcore in BIOS up to 1.33v, which seems to have eliminated any instability. However, temps and voltage are way up in HWmonitor, with a max voltage used of 1.380v.
