Question

PC crashes (blue or grey-screen no text) during gaming

Jul 23, 2019 7:23AM PDT

Hello all,

my PC crashes randomly when I play a game (its a DirectX 12 game).
Sometimes I can play 5h without crash, and sometimes it crashes every 30mins.
During gaming the PC crashes, either into bluescreen without text or into just grey screen.
Then the PC tries to reboot, and is not able to (its hanging in an kind of reboot-loop, and is stucked). So I need to hard-reset it via the power button.

I checked the temperatures during gaming:

GPU goes up to 60-75°C
CPU goes to 50°C

My system:

CPU: AMD Ryzen 1700x
GPU: AMD Vega 56
SSD: M2 SSD Samsung EVO 960
Motherboard: Gigabyte K7 gaming X370
Cooling: NZXT X62 cooling
PSU: bequiet Dark power pro 650W
RAM: GSkill Ripjaws V 3200Mhz

No overclocking. Newest drivers, newest windows, newest BIOS.
I am really almost frustrated, because I cant figure out the problem.

I discovered also issues during rendering of videos. I was only able to render videos to a filesize of 5GB, anything more and it crashes.
But here it crashes differently, its then a bluescreen with error message (MEMORY_MANAGEMENT)

I did the ram check by windows, no errors found. RAM is set to 3.200MHZ via XMP profile.


I hope you can help me.


Best regards

Fab

Run memtest86 (free download) for a few hours. No errors allowed.

Because it's new you have warranty and RMAs to use.

Lower the ram speed to 2666 and test.

You are overclocking the ram circuits on the mobo.

Do post that speccy.

I just logged all my hardware with MSI afterburner. I played for 3h roughly, then it crashed.

Here is my full report with all the data's and graphs:

anything suspicious?

No HML app here.

I use Speccy for a look.

Bob__B noted a big item. Try that.

3 Hour crash.
Jul 23, 2019 3:03PM PDT

That can tell us the game is buggy or there's a heat, driver or settings issue. Bob__B noted the overclocked RAM circuits and for the rest you can share more or research more.

You were asked to do 2 things
Jul 23, 2019 3:50PM PDT

Instead you went off in a different direction.

Perhaps your best option is to take the machine to a service counter.

Yes
Jul 24, 2019 8:59AM PDT

Yes my 1st monitor is an 240hz Full HD monitor.
My 2nd monitor is an 4k Monitor (60hz).

The game runs also on 240hz.
I discovered sometimes a strange bug, that 1 out of 10 times my game starts up, and I wonder about the shaky footage (a lot of tearing). Then I see that the 240hz monitor is suddenly running on 60hz, causing a huge tearing. If I restart the game or the PC, and start up the game again, then its on 240hz again, and running perfectly. This is a very strange bug I discovered.
I also asked myself if it could happen, that during gaming the monitor suddenly switches to 60hz and causing this PC crashes?

240 may really be 120 Hz

Would not expect to work well.
Jul 24, 2019 8:53AM PDT
https://forums.tomshardware.com/threads/downgrade-amd-vega-64-for-better-1080p-144hz-gaming.3449114/ and many other discussions peg this as a solid 1080p 60+ FPS gamer. You have essentially gone way beyond that with the 240Hz and the 4K display. No one I know will say this will work out or be stable.

If this was mine the 4K gets unplugged and I try runs with 1080p @120Hz output.

There are far more complaints about the GPU than I expected. Because of this I do not expect this PC to be stable between your GPU and the motherboard.

-> So the problem here is you have a PC where there is likely to be more than one problem area and both are not cheap to swap out.

There are other issues in the Speccy.

1. The CPU didn't report in. In many ways. The core count is wrong.
Right here is a problem. Ask in their motherboard support forum which BIOS they suggest for your configuration. I've yet to see this CPU fail to report is so something is up.

2. Under Scheduler in the Speccy report I see things that get tossed all the time. From driver finder, bluestacks and what else. Clean house and install the BIOS and drivers the motherboard maker suggests.

I rarely write this but this PC is a mess hardware wise. Let's hope the motherboard maker and some cleanup can help but given what I read about that board and that GPU these may have to be swapped out.

It might works
Jul 25, 2019 9:12AM PDT

I tried yesterday a 6h game-run. It worked without crash.

What have I done:
I disconnected the 2nd monitor (4K).
Furthermore I also undervolted a bit my graphics card, because I read that it runs better like that.

I put the Voltage at highest performance level from 1200mV to 1150mV.
The Mhz of the GPU I put at the highest performance level from 1592Mhz to 1480Mhz. The other performance I decreased also by 5%. The max VRAM speed I put on 950Mhz.

Now I dont know which one helped, if its the 2nd monitor or the undervoltage.
I also deinstalled some unnecessary software from my PC.

I hope that yesterday was not only a lucky day. I will further have a look on it.
Does it really take that much strength from the GPU, running a 4K monitor as 2nd screen? Its only a blank windows screen, not transmitting any video etc.?

For the CPU Core count I still did not receive help in the motherboard forum. Can you help me with that?

So good news.
Jul 25, 2019 10:01AM PDT

As to the UHD 4K, even with a simple screen that's a load on the GPU and more work, code is being run so more opportunities for an issue in many areas. UHD 4K is not a simple load even for a static screen. Video RAM used is 4 times that of the 1080p screen too. There are so many reasons turning that off can help that I'll stop here.

As to the CPU, it's truly an odd issue that I have yet to fix as the usual fix is another motherboard if there are no other clues to the source of the issue.

Is there more to this PC's story or history?
1. "I changed the motherboard, CPU without a clean install of the OS"?
2. The owner does not install the maker's chipset drivers and such?
3. Is there some rootkit infection? I posit this because of Bluestacks and other items in the scheduler.

4. Let me lambast Driver Finder and Microsoft's own driver updater here. Drivers do not wear out or break once you get it working. There's a lot of wisdom in "Don't fix what's not broken." Just last week another PC where it worked fine until Microsoft's Driver Update broke it. Driver Update apps are no better. OLD SCHOOL WORKS HERE. Disable driver updaters and Microsoft's as well then install the drivers for your PC as told by the makers and once working, stand still and enjoy your working PC.
