Question on the X264 stress test. How do you know when it fails? does it crash? does an error message pop up in the cmd prompt? Just curious what I should be looking for while I run this.

Question about vcore for you guys. It's been a long time since I've overclocked and so relearning everything.

My setup:
6700k (SL binned at 4.7 - delidded)
Gigabyte Gaming GT (afaik this is the gaming 7 with a few upgraded audio components)
16gig 3200 ram (running at 1300 without xmp while messing with overclocking)

I'm trying to get 4.7 at a decent vcore (SL says it passed RealBench at 1.408). It seems to run fine but running x264 with HWInfo the problem I keep having is that my vcore keeps going up to 1.45 or a little more (1.455). This is while vcore in my BIOS is 4.1, 4.05, 4, 3.9, 3.8... doesn't really matter. I read a little about LLC and tried to change those settings a little but "Low" and "Normal" see the system crash while "Turbo" and "Extreme" give me the same 1.45 results.

Just to make sure as well - in HWInfo I'm reading vcore on "Core #0 VID" at the top.

Do any of you have experience with this? Do you know why the BIOS won't stick to the vcore I'm selecting?
No that's vid, vcore is further down (see OP)

Yes, I remember seeing some error msg in the cmd prompt when mine wasn't stable. Or the usual windows hangups like freezes or bsods.

sounds good. So far it's been running 1.5 hours with 16 threads. Figure I'll let it run about 5 hours and call it good. 4.7ghz 1.344v under load. Temps stabilized between 66-67c without having to crank my fans to 100%

Look for the actual vcore reading, not VID.. they're separate.

Yeah, I see it now. There are a few other called vcore so I wasn't sure. It's pretty solid right below whatever I set it to now so that's good.

4.7 at 1.405 seems solid so far. I think I might be able to go 4.8 with the remaining vcore, but I think I'll just stop here.

I'm only hitting low 60Cs running x264 as well so the delid and DH15 are working well.

I hit 65-67 doing the same test, but I'm not delidded and I'm just using the packed in thermal compound. Bet if i got something better I could bring the temps down at least 3c but I'm running less vcore than you are. 1.344 for 4.7ghz.

in one hour that'll make 5 hours of x264 16T

Got my 4.7ghz stable! now for 4.8


Edit:
Currently testing at 4.8ghz@1.404v Temps are THE SAME as 4.7ghz@1.344v but I also lowered my DDR voltage to 1.2v and dropped its clock rates back to stock (DDR4 2400) so maybe that helped? I don't see how it would effect the temps. This thing kept getting hotter and hotter then suddenly when I set it to 1.4v it started running better. I don't even have any Vdroop now. I was expecting the voltage to drop to 1.39v

Delid would be something to try. 4.7 wasn't hard to reach but the next step up to 4.8 was quite big and prime95 pushed up the temps so much that even my custom loop couldn't handle the heat. After 30 minutes on ~1.45V it throttled because of the temps.

1. Mobo: Asus Z170 Pro Gaming
2. CPU: 6700K
3. Mem: DDR4 16GB Corsair LPX 4x4GB 3000Mhz (körts i 2133)
3. Cooling: Custom Loop
4. OC: 4700MHz (47x100)
5. VCore: Adaptive 1.350V, LLC 5, Load 1.376V

50 passes in x264 (16T, high) throughout the night worked out quite alright in 4.7
