Hello,
I've been reading about and playing with OC for few weeks and not the first time, but this time I want to keep OC 24/7 as I'm upgrading GPU.
My rig:
From what I've read 3.6GHz should be possible even on stock cooler with just 18x multiplier and not touching VCORE. So this was my starting point.
With this setup I can fully (around 2h) pass "In-place large FFTs" on prime95 however core temps are touching 59C and averaging at 57C, which seems too high on stock voltage. People seem not to hitting 55C with 955BE/TX3 on same OC.
However I can't pass "Blend" - program crashes at random times running more than 30 min but less than 3h.
I'm not touching PC while running prime95 and PC on WIN10 is just running HWmonitor, prime95 and eset AV. I've tried 1.4125v (max 59C) and 1.4250 (max 60c), but prime95 just crashes running "Blend" in same fashion.
I've never had BSOD, restart or calc error while running prime95, just "prime95 stopped working", which from what I've read points to low voltage. However I can't imagine 18x requiring more than 1.4250v.
I know it could be RAM stability, that's what "Blend" failure points to, BUT it still doesn't make sense why tems are so high.
My guesses: bad/badly applied thermal compound (one that came with TX3) or rubbish MB?
Also my BIOS doesn't have option to disable Cool'n'Quiet, so even setting voltage manually MB still changing multiplier and voltage. I've disabled/enabled Cool'n'Quiet with Overdrive (with OC done in Overdrive or BIOS) with no difference in stress test. I've ran latest tests with Overdrive uninstalled with same results too.
So this really makes me wonder what is going on
. Any ideas guys?
PS.: please don't say don't use Overdrive, I know it's bad, but as I've said same results with app uninstalled too.
