Black Screen issues

[humbug]

Powercolor PCS+ R9 290, 18 Months old.

I have never had any Black Screen issues with this card in the past, over the last 4 to 6 weeks its become a problem.

Whats happening is the screen will go black and then into standby, the computer is also frozen and i have to hard reset, alarmingly for about 1 in 10 of this happening i get a Motherboard error beep and a GPU error light. when that happens it will keep doing it until i physically remove the GPU and put it back, after than it will start again and run fine.

It Black screens like this very randomly during gaming, at idle and browsing, it doesn't happen often.

Any ideas whats wrong?

Had something very similiar with my first 290, had to RMA it in the end. Could be GPU Vram issue?

Its clocked at 1350Mhz out of the box, it did it at 1300Mhz. i might just test that properly by running it at 1200Mhz?

I don't want to RMA it yet because because it doesn't happen often and i can't get it to do it by doing anything specific to it, like stressing it. it just does it at random.

This is the most worrying thing to me, has anyone else with black screen issues also have this happen to them?

the computer is also frozen and i have to hard reset, alarmingly for about 1 in 10 of this happening i get a Motherboard error beep and a GPU error light. when that happens it will keep doing it until i physically remove the GPU and put it back, after than it will start again and run fine.

Have you tried reseating the card and the pci connectors, just to rule it out?

Is your PSU OK as well?

Many times yes, sometimes i have to take it out and put it back in the get the PC to start again, but its doesn't fix it.

Have you tried removing the overclock altogether to see if that helps? that would always be my first guess in the middle of summer.

Having to remove the GPU before it will work again seems a bit power supply related to me though, it sounds like there's some sort of electrical protection mechanism kicking in. That could just be a result of crashing/faulty card though.

I'm now running the Memory at 1200Mhz, if it does it again i will try at 1000Mhz.

I'm thinking PSU could be the problem but i'm no more sure of than that i am Motherboard or GPU, the PSU is a 4 year old XFX 750 Pro.

I'm running the memory at 1200Mhz, it seems fine so far but it will take at least a week for me to know for sure as it can be days between it working fine and then not.

I will give it a week, if it doesn't crash i will put it back to its 1350Mhz, if it does it again at that i will contact the retailer.

I have also striped the computer down, cleaned it up and had a close look, everything looks in good order, i also took the PSU apart, cleaned that out, again it all looks healthy.

I don't get it, i have had it for 18 Months and its been solid, only now is it doing this.

I would try a more recent bios for the card. I would only get black screens if I overclocked the memory to far and the benchmark would randomly black out causing me to need to hit the reset button. Newer bios version just gives be a bit of gfx corruption instead telling me I need to back off so maybe the latencies have been tweaked for more stability with the memory in newer bios versions.

This is the one I am using https://www.techpowerup.com/vgabios/162939/powercolor-r9290-4096-140814.html which is the last one supporting elpida ram as far as I can tell.

Thats a 15.047 BIOS, a lot newer, i'm running a 15.042.

How old is your PCS+? they got a revision about 8 months ago, mine is the old PCS+ and i don't think the Rev-2 BIOS works on mine.

For example the Rev-2 PCS+ has 6 Phase VRM's to my 5.

4 Days trouble free in Cryengine at 1050/1200, clocked it up to 1250Mhz Blackscreen.

The problem is it seems to be fine at its factory clocks in gaming and benchmarking apps, apart from that one time in world Of Warship's, so outside of Cryengine its extremely difficult to get it to Blackscreen.
