Question

Issue with performance and GPU turning off

by Jun 17, 2018 11:26AM PDT

Hello there,

I have a problem in terms of my PC.

It all begins when my GPU starts to act strange. During normal work (couldn't find the way to simulate it) the GPU just turned off (black screen), the fans run at 100%, however rest of the system worked fine (music, I/O operations, etc).

It happens randomly. Sometimes when I use browser, sometimes when I play, sometimes when I develop.

It happened few times so I'm a bit worry.

I've tried to do some tests using OCCT however the results do not tell me, what is really wrong.

When I run:

- CPU: OCCT, CPU: Linpack, GPU: 3D - everything runs nice and smooth,
- POWER SUPPLY - it runs for like 10-15sec, then it freeze for few seconds and continue over and over. When it freeze, you can't do nothing except mouse move.
In the following link you can see the results of mine 20min test of Power supply: https://imgur.com/a/UZVgp8N

My PC specs:

- Corsair Vengeance LPX DDR4, 2x8GB, 3200MHz, CL16
- AMD Ryzen 7 1700
- Palit GeForce GTX 1080 Ti GameRock Premium 11GB GDDR5X
- MSI B350 TOMAHAWK ARCTIC
- XFX Black Edition XTR 650W

I have no idea what other tests should I perform in order to get know, what's is wrong and which part should be send for RMA.

Can someone help me with that? It makes me doing my work more difficult then it should be.

Best wishes,
Thyler

It's another Ryzen.

As many have learned the BIOS SHALL be current. There are folk scared of updating this so for them they RMA the motherboard until it arrives with a current BIOS.

Read https://www.cnet.com/forums/discussions/help-with-weird-crashing/ about another way to investigate but your pictures seem to show ODD Voltage drops on the CPU. Maybe this motherboard is just not up to the task?

Motherboard you say?
I have latest BIOS installed. Also I've set everything to stock - still the same.
Tried to run RealBench test. After few minutes (3-6 - it depends) the screen just turns off and test stops. It says that something bad has been found, but no information what.
After that, when I checked HWInfo I saw, that my GPU Power was greyed (last know value was 184W, while CPU at same time around 100W). From this moment the power value is no longer updated until I restart app.
Have no idea what to do... Send motherboard for RMA? Maybe PSU? Or GPU? Do some more SPECIFIC tests? Can I somehow exclude one part and make sure that it's ok?

Your tests and charts

Point to something odd going on with the CPU voltage jumping around under load. To me this points to a motherboard issue.

Again, to me it's clear it's something there. My guess is that you want to debate this. Sorry but I won't do that. It's clear to me that there's something odd there and you get to talk to the motherboard maker to see what they say next.

I rarely RMA motherboards.

I find that if I find a problem it follows to the new board.

For Ryzen I'd pick a board used by PCMR builders. Here's the link:

As to the GPU, if it's a new GPU then it's low on my suspect list because so few fail.
HOWEVER there are folk getting GPUs from BITCOIN MINING OPERATIONS and so far the news is grim. These appear to be removed because the GPU is tossing errors.

As to the PSU I took a look and spec wise looked OK. Single rail. Not on my suspect list.
