Skylake Overclocking Guide [With Statistics] - Page 565

post #5641 of 11309
Low 70s? Wow what frequency and chip are you running. That's incredibly low for small fft. I'm running i7 6700k at 4.8 Ghz 1.405 V and I hit 98 pretty quick so I stopped. And this is using a h100i gtx liquid cooler

Those of you who have run the HWBOT x265 test know that you need to have HPET active for Windows 8 and higher. I recently realized that having HPET active lowers my Intel XTU benchmark score significantly.
Wondered why my score had suffered so much from when I first ran it with Skylake.

Whoever wants to test this can enable/disable HPET in Windows from an elevated command prompt with these commands:
bcdedit /set useplatformclock true (then reboot) enable HPET
bcdedit /deletevalue useplatformclock (then reboot) disable HPET

6700k at 4.7Ghz, vcore set to 1.340v in the BIOS, LLC level 5, HWinfo reports 1.328v. This is with a Noctua NH-D15 in a Cooler Master HAF 932 case. Ambient temp about 65f/18c.

I may try again to hit 4.8Ghz, but the first pass at it was taking a lot more voltage, and it still was not stable. I generally stop at that point of diminishing returns.

Edit - Now I can't seem to keep all workers running for an hour. Ambient temps are up today, so I was in the mid 70s at that voltage, but seems it needs more. I think I might just abandon prime and work on x264.

I'm at 1.44v/4.7 and I see max 65c small fft in latest prime95. The trick was metal paste on die after delid. Previously I was approaching 80-100 depending on what was on there.

Oh for sure. If I could get someone to print me the delid tool I would be all for it. I don't trust myself with such an expensive chip for the razor method and the darn pcb is so thin I can't risk it on the vise method. I may send it in and get it down but I don't want to be without a chip while I wait.

I have some voltage questions if anyone fancies helping?

4.5 @ Adaptive max turbo 1.35v - Max 75 / 86 in realbench / P95 28.7 blend. Took maximum of 1.36v according to HWMonitor. Not happy with temps, stopped P95 after 15 mins.

4.5@ Auto - Max 64 / 81 in realbench / P95 28.7 blend. Taking maximum of 1.39v. 1 worker stopped with error after about 50 mins in P95, so close!


I don't understand how auto takes more v but is cooler, can anyone explain this?

Only using Cryorig m9i cooler, so had set a stable 4.5 as my target.

How abt using HWINFO64 as in OP (look under "Information Before Overclocking"). Does it show vcore similar or different to HWMonitor?

Wow, I completely missed that HWInfo was different to HWMonitor. Oooooops!

Cheers, will try.

Ok so I'm really looking into delidding my brand new i7. In the past on my 4790k I used the vice method but in worried the thin pcb will screw it up. I'm thinking about giving the razor method a go? Is it any more difficult? Is scratching the pcb board a real issue? I'm trying to gauge if there is a high chance of screwin something up would I be better off sending it out to have it done.

I've had Silicon Lottery delid 3 of my Skylakes - I have been veryhappy with all 3 smile.gif
