Question 6700k OC questions

So it's been about a year and a half since I've played with my 6700k OC, back when I got it I was able to run 3DMark with valid results at 5.0GHz but wasn't super stable and I decided on a safe OC for 24/7 at 4.7GHz, 1.38v.

Today I decided to play with it again and I think I found a stable 4.9GHz profile. I used Aida64 and HWMonitor with CPU-z to see what was going on with temps/voltages.

CPU - 6700k
Motherboard - MSIZ170 Xpower Gaming Titanium
Latest BIOS
Custom loop 280mm x 60mm + 360mm x 30mm rads

I know max temps are a little on the high side and the vcore is a little high as well, just wondering if I should tone it back a bit or if I am ok...

Things are fine at 4.7GHz just checking if it's worth squeezing the last bit out.

Aida is a super stress test to see if its stable.

Even during gaming all day, you won't stress it that much so go for it.

I tried it for a few rounds of PUBG and my PC crashed with a black screen and the broken audio, so loaded up my 4.7 profile and will have to play with it more, it was solid for 4 games and the 5th one crashed... black screen so I have to check the cause later...

The computer has rebooted from a bugcheck. The bugcheck was: 0x00000101 (0x0000000000000018, 0x0000000000000000, 0xffff888195566180, 0x0000000000000004)


Problem Event Name: LiveKernelEvent
Code: 117
Parameter 1: ffffbb8b1a5a1460
Parameter 2: fffff8030b9ece38
Parameter 3: 0
Parameter 4: 4d8

Those are the reports I got.

I think that's PUBG not the comp.. I've had problems with that game on a couple of computers till I stopped playing last October.

And I thought it was my overclock but nope.. PUBG has -Redacted- code.

Try other games.

You already know that profanity is not allowed in the Tech forums.

Try running memtest as well, just to be safe. Use the latest UEFI memtest from passmark, v7.5

You are right, good catch! I had not seen that they had a newer one out.

Well I played around with it some more today.

Bios settings that didn't crash during 20 minute Aida64 run:
49 multiplier
CPU core: 1.450v
LLC Line 3
Everything else CPU related on Auto

Aida64 showed:
CPU vore voltage at 1.478v
111.24w Package power
Max Package temp was 88c avg was 82c
Max core temp was 92-95c avg was 73c

I tried running XTU benchmark and it BSOD half way through (sys service exception)

LLC Line 3 in BIOS is basically flat, Line 2 raises a bit and Line 1 raises a lot, given the voltages I don't think trying lines 1/2 would be good (could be wrong though)

Going to try some other benchmarks and see how it goes with these settings, any advice on tweaks is appreciated.

EDIT:

Tried some Cinebench R15 and got a 1027cb so checked that on HWBot, placed #141 for x4 on H20 so I'll take it.

I don't think I'll get 5.0GHz stable, I'm still not convinced 4.9GHz is 100% stable right now.
A delid might help temps, not sure if that's my wall, not going to delid though as really I don't want to at this point.

IMO, 1.4 and up is too high for Vcore. I would settle for lower with fewer volts.

100% agree, I run 4.7GHz @1.380v for 24/7.

I was just trying to see if I could get back to 5.0GHz for a couple runs to see if there has been any degradation or performance changes since Q3 2015.
