Hello guys hope you can help me here.
It’s been about 1 1/2 months now that I built my new TRX40 build with a 3960X and I’ve been fighting it now since almost the beginning to get it 100% stable.
At first it ran very well then I tried doing some memory OC (tightening timings) and got hell for it it seems, cuz I noticed very strange instability (sudden slow freezes at random intervals).
Figured out that my G.Skilll 3200 B-die kit doesn’t like the heat in my PC with 3200MHz so I dialed it down to 3066 which is now Memtest 1000% stable.
So with the weird random slow freezes now gone, the next kind of freeze has been making an appearance: freezing when left alone for the night with encoding tasks.
And here it’s getting weird, I do the SAME tasks with the SAME settings over the day and everything works without issues, then I leave the PC on over night with the next batch of encoding tasks and about 1-2hours after I leave it freezes, while I have the same programs open as I have over the day with the only difference being that I’m on the machine over the day and doing MORE stuff at the same time, like gaming for example.
How does that make sense?
So system specs (* indicates carried over from previous build):
AMD TR 3960X (slightly undervolted offset -0.03V)
Be Quiet Dark Rock Pro Cooler
*32GB G.Skill B-die RAM 3066 CL14 (Normally a 3200 kit but unstable in memtest)
ASUS Zenith II Extreme (newest BIOS 1101)
*NV 1080Ti (undervolted)
*AMD 580 (undervolted, underclocked)
*PSU: Silverstone 1200W
OS: Windows 10 LTSC 1809
CPU: Idle ~65°C load encoding: swings between ~78°C and ~86°C at the highest
RAM: idle ~58°C load: ~72°C (this is still memtest 1000% stable)
Chipset: ~91°C (fan is mostly blocked due to GPU)
Note: Those are DAY temps; they are LOWER over night due to cold air and PC only freezes up over night.
I’m honestly at my wits end here and have never seen such a weird thing so I hope you good people can help me.
Also tagging @wendell maybe you have seen something like that.
