AM4 B350/X370 black screen crash thread

What exactly is triggering these problems? I'd like to try it out.

I have had

1700 @ 3.8ghz @ 1.275v (bios)
B350 Tomahawk
16GB DDR4 @ 2933 @ CL14 (3066 @ CL14 more recently with updated bios)

pretty much since launch with no black screens where I wasn't tweaking.

I had them as I was testing overclocks beyond 3.8ghz and before I settled on 1.275v. However nothing in a couple of months since finding that.

I was testing a beta bios and have had one issue which may fit what you are describing. The M.2 PCI-E drive (my boot drive) would randomly disconnect. The BIOS doesn't actually recognise and sometimes this would cause boot problems. This was on a beta bios however.

With the MSI B350 Tomahawk, l found a post on UT discussing any changes to the fans via BIOS would cause cold boot issues. I can confirm this, so leaving then to "default" does not cause the cold boot black screen issue. Command Center also causes this if you fiddle with the fan curves/dc/pwm etc.
 
I have a custom fan profile. No such issues on v1.3 or v1.5.

I had issues on the beta bios where if you entered the bios after setting a custom profile, the CPU fan profile would go back to default settings which was annoying.

No black screens though.

No way I could leave the fans to default, way too loud.

How long was OCCT running for compared to handbrake?
Click to expand...

Generally ran oct for 2 hours.

Have backed down my known to pass 3.975 to 3.95 with same votlages, and upped my ram voltage to 1.4v (which the board seems to put to about 1.425v)

Passed a two hour and a three hour occt, and several hours of tpu memtest - I will test that more overnight.

Will continue to leave off all gpu software and see how things go.
 
I'm not even going to troubleshoot the display cut out any more.

So long as it doesn't happen under normal usage.

There's only so much time on can spend trying to get a ******* pc to run without issue :D
 
As I'm investing a lot of time in lords of the fallen on PS4, and was out and about, figured I could spare the time for more testing.

I found the display cut out could happen all stock - without any gpu software!

I upped the SOC voltage and supporting phase/llc, etc, and it went away.

So, back on 9945 (that was on 1202 btw), and currently pushing just ram at 3066 with cpu at stock.

Chucked the SOC voltage up to 1.2v, and had some issues still, but relaxing timings, etc. I have managed 2 hours occct, 4 hours tpu memtest, and an hour of realbench without display cut-out.

Am going to re-enable gpu software, and see what happens out of curiosity.

Will probably run a 3 hour occt this evening and hci memtest overnight.

Am not playing with cpu speeds at all until I have spent some time with jsut ram at these speeds.

But am thinking it's just down to it requiring a high voltage on soc - normally didn't go over 1.15v

That would make sense given the amount of ram you have using all 4 slots.
 
You'd think it would translate more in memory test failures...

Part of me suspects it may still be nvidia driver related - that is responsible for the largest latency spikes I see in latencymon. so perhaps when it hits one of those spikes when it's under heavy load, it then takes too long and it 'falls over'

so far have done a number of tests, including up to 3 hour occt, 1 hr realbench, and overnight hci memtest , and now started off another tpu memtest, and not getting the display cut-out. This is with gpu software installed.

Not sure how safe it is running soc voltage that high though... but even 2400 required over 1.1V
 
Ah, no. The board's had it's day of behaving... tpu memtest now crashing, despite yesterday running for hours, and hci memtest passing many hours.

Crashed once, and though fine, will drop to 2933, and crashes still, just differently.

But at least the display isn't cutting out :D

Give the new bios a go. Was able to bring 3466 CL16 down to 14.
3600 will boot but not stable.

I am. Same thing with display cutting out.

But!

I ddu'd the nvidia drivers and have left it without any drivers, and haven't seen the issue since.

Now, not saying it's just nvidia drivers to blame. Think it's a case of the latency spikes I saw from nvidia drivers, combined with running tpu memtest or occt, which cause the system to pause for periods.

Still early to say with certainty though.

If this is the case, I can live with it, knowing what the issue is, as it only happens stress testing (I think)

Edit: but then I have been here before where thought I had got to the bottom of it, only for it to kick up again in a day or two.

Nvidia and ryzen don't seem to play nice. I'm scared to update mine in case I end up back at square 1.
 
Still no blackout, with chopping and changing stress tests.

Was actually testing with the ram at 3200mhz. Couldn't believe I could boot at that, let alone be stable enough for hours of testing!

In the end, memtest did throw up an issue, but still impressed.

Have dropped back to 3066 and letting that run memtest overnight
 
Got a new C6H in today. Rebuilt the computer again. CPU to 36x and everything else at stock...2 hour Aida test! Seems something was wonky with my last board. So happy to finally have a computer that can at least be stable at some setting.
