Hey guys,

my new build has a weird issue where the screen freezes for 2-3 seconds,
then turns black for another 5 seconds and after that it goes back to normal.
there is no consistent way to reproduce this problem, the freezes seems to happen randomly.
task manager shows a 100% spike on the GPU when the video output reconnects after the blackout. Framerates in games lock fine, CPU test in Cinebench also no probleme.
I also tested the GPUs in Blender 2.8 and there was no issue.

System:

Motherboard: ASRock X399 Taichi (BIOS 3.50)
CPU: Ryzen Threadripper 1900x
Memory: GSKILL 4x 8GB DDR4-3200 Memory
GPU: EVGA FTW GTX 1070
VBIOS: 86.4.50.0.72
OS: Windows 10 x64 (1809)

Cooler: Corsair H100i Pro

PSU: 1000 Watt Seasonic Prime Modular 80+ Platinum

Harddrive: Samsung 2TB SSD 860 QVO

Stuff i already tried:

1) installed latest drivers

2) switched out GPUs (GTX 1070 and RTX 2070)

3) change DVI to Displayport output

4) disabled IOMMU in BIOS

5) disabled CSM in BIOS

6) disabled HPET in BIOS

7) tighten screws on CPU socket

8) reinstalled CPU cooler

9) boot on only 1 memory stick

10)cleared CMOS

11) reinstalled Motherboard BIOS (3.50)


thank you <3

Try reseating all RAM sticks in A2/B2. You may want to shuffle them in these slots too.

Re-seat the CPU. You will need to remount the cooler anew.

Cheack all cabling, clear CMOS once again, re-deploy Win again.

It may also be worth trying the GPU in different slots.

If you take a look in system event viewer does it show any errors or warnings when the display drops out? Sometimes TDRs (timeout detection and recovery) can be caused by drivers.

Yes, this can be done too and it's way more elegant.

I rarely recommend such things these days. I just pull the bazooka and shoot.
