[SOLVED] Timespy shuts down PC shortly after benchmark starts ?!

[☺rEZ☺]

Update: 3dmark actually helpoed me diagnose a faulty PSU while other benchmarks ran fine these were heavy enough to consistently point the finger at my PSU so replaced PSU -> fixed
ALL my issues.

Issue: Timespy bench is shutting down (not rebooting) my PC within test 1 or the start of test 2

Windows error logging just mentions there was an undscheduled reboot due to the PC freezing and doesn't mention specific error codes unfortunately

Note: no additional programs / bench / OC / tweak tools running in the background

All coolers on turbo CPU is 23 C (outside 31 C heatwave), GPU is 35C at boot atm

ALL components stay well within normal operating temps: CPU 23C @ boot / <50 stress, GPU 35 @ boot / <70 @ stress , mobo 24C etc.

My specs:

OS: W10 1803 latest updates as of 30.06.2018
CPU: AMD FX8350 @ 4.2ghz (also tested OC to max 4.4ghz)
GPU: RX580 8gb nitro+ a super stable card zero issues
AMD driver 18.6.1
MEM: 16gb ddr3 1866 at stock timings
Mobo: m5a99x evo r2 with latest manufacturer bios
PSU: 750W
SSD drives

Benchmarking with everything on standard (just bought yesterday) except:

Demo off
Furture mark system info is on (all settings on)

Things I checked:

. Everything on stock clocks and defaults in bios -> still crashes timespy
. Increasing cooling to insane levels -> still crashes timespy
. DXDIAG -> ok dx12 installed fine
. Disabling CPU and GPU info in futurenark diagnostics -> still crashes timespy
. Disabling ALL Systeminfo logging -> still crashes timespy
. Other dx12 apps work fine including API overhead test
. The other 3dmark benches like Firemark, API overhead test, the stress test work without any issues
. alternative benchmark tested again with current settings: superposition bench has no issues,
. games and apps have no issues....


So is it the driver or the benchmark or both?

System shutdown = PSU too weak. If it literally powers off, it is always power supply issue.

I agree , it's the psu . What brand is it ?

W00t two replies

Hmm going to check if the new Systeminfo update helped and double check mobo power cables still attached ok otherwise time to upgrade that ol' PSU then ... I suspected as much really but hoped it was still fine and this was just a known driver / benchmark issue.

Current PSU: OCZ stealthstream 2 700w which runs everything else fine @ 100% loads including other torture tests / benchmarks except 3dmark Timespy DX12 and OpenCL @ 100% GPU loads fine. No spring chicken anymore it seems...

So... nope updating 3dmark and cable reseat didn't help and still intermittent shutdowns / power off. New PSU being installed -> Corsair gold rating :)

Will post here if the issue doesn't go away after I install the new Corsair PSU

Hi so can confirm the PSU was getting past it. Praise be to 3dmark for helping me expose the true culprit for my rig's very intermittent shutdowns and graphical glitches.
I was able to reproduce the issue every time ( I couldn't on other benchmarks) on the extreme 3dmark benchmarks which helped me localise the issue.

Yep faulty PSU confirmed, cool that 3dmark is so consistent at this as I was able to pinpoint faulty PSU this way :D

Time Spy Extreme is indeed pretty much the heaviest thing you can run on a system today. If your system gets past it in even in stress test mode, you can be fairly certain it is stable. If it can do even without thermal throttling, you also then know your CPU and GPU are properly cooled.
