AM4 B350/X370 black screen crash thread

I have, all the way upto 3.85, same issue with insane amounts of heat!



Currently on pass 4 of 4 on memtest 0 errors. Heat is not an issue mine was crashing at 60 degrees with stock cpu and 2133 ram. Next step is SMT.
Future step will be to overclockers to pick up a 7700 if this continues!

For the life of me, I cannot find where to disable SMT on these Asus boards.

I read on another forum regarding the B350 there simply wasn't an option on the B350 Prime plus.

But I can't see anything I can relate to SMT on this board either.

Currently got everything stock with CPU voltage set to offset +0.1 and DDR voltage at 1.25

It only became an option on the msi in the third iteration of a beta bios. Might be worth scouring the asus forums for an updated bios.
 
I have now gone from a £173 kit of ram, to a £210 kit of ram, and now a £240 kit of ram.

Only common factors then will be CPU and GPU... might rip the gt 730 out of media pc to elimintate that later.

Once I have eliminated ram and gpu, only thing left is the CPU... I seriously doubt it's PSU.
 
I'm hoping the memtest will be done in round 20 mins. I will then disable SMT and run realbench and let you know.
As you said in the op sometimes i can pass a test, do it again and have it immediately fail, Cinebench can manage 2-3 runs before I get the black screen.
They really have ****** up this launch. I've been looking for an x370 board but there is nothing anywhere!
 
Ok so mem test passed with no errors, took just under 4 hours.
I've disabled SMT (that was fun!) Got stuck in a boot loop removing battery and keeping it removed has at least got it booted up again.
I'm now going to test real bench
 
Does the computer freeze or is just a black screen? I've had a few issues in the past with dodgy DisplayPort cables quality seems to be all over the place.
 
SMT Disabled - realbench crash 2 mins in 60 degrees.
Currently running prime 62 degrees 3 mins in the longest it's ever done.

Screen goes black and the lights on my GPU begin to flash. Cables are fine and only happens when all cores are under sustained load.

I'm not really sure why loading the CPU would cause the GPU to go offline, it must be some sort of power issue either PSU or board. Does disabling overvoltage protection help? I noticed it's an advertised feature of that board.

You sir might be on to something! I've replaced enabled SMT turned over voltage and current protection off. Now I'm 5 minutes in with no error, the longest it's ever managed. If this makes 30 mins I owe you a beer. I kid you not only an hour ago i told the Mrs not to make any plans as I'm going to overclockers to get me a 7700k!

No issues with 3 runs using gt 730 rather than gtx 980ti - so, something GPU related somehow.

I will have a look at those settings now - jsut got to put the 980ti back in.

And now I have the Crucial memory delivered (got to love primenow), but probably not necessary.
 
Can't find those settings anywhere... man these Asus BIOS are pitiful on these boards.

Have put all the settings I could find allowing higher current %, etc, up a bit, and trying again now with 980ti.
 
I only have a Corsair 430w. I suppose a PSU is cheaper than buying a new kaby lake setup.
I've never had a PSU not able to keep up it's always been a case of it bombing out under load. Not just losing the display
 
It might not be PSU I'm just speculating, if you can borrow a bigger PSU from someone or go to OCUK to test with another I'd do that.

Does disabling overvoltage make it more stable or the same? if it helps then there's a good chance it's power related.

edit: the only other thing I can think of is there's some sort of bug with Ryzen motherboards and certain NVidia GPU's.
