R9 390 keeps freezing

[Doccy_D]

Hello, I am having trouble with the rsi r9 390 gpu. What happens that when under stress it 'freezes', the screen holds and and the only thing I can do is reset the pc, and if I turn it back on too quickly, I get the no GPU detect signal from the motherboard.

I used afterburner to set all the sliders to the left except fans, which I set to max. I have a temp in the low 30s when idle, and high 40's low 50s shortly before it freezes. Any suggestions please?

I use a 700w cooler master psu and a 990fxa mb with 16gbram, and 8core cpu at 4.40 ghz if that helps.

POSSIBLY PSU, not that it isn't powerful enough, but not the vest make and the 390 can pull Some big wattage.

Wipe all drivers using ddu then reinstall. Get rid of afterburner and run all stock and see if still happens.

Your Coolermaster PSU is probably not able to hold up its end of the log. If it is from their "Elite" or "Extreme" lines in particular, it is almost certainly overrated near-junk. It probably won't kill your system like real junk, but it may not be able to power it either. A quality 650W PSU would be sufficient. Make sure it gets good airflow through it (e.g. if bottom-mounted, it isn't muffled by carpet).

 

[burgessanthony]

Yes. My system pulls about 400w peak under load. Your fx8xxx will add another 40w to that. So lets say 450w worst case. Hence a quality 600-650 psu is fine. But your psu although rated 700 peak, may deliver much less continuous, and suffer when suddenly loaded.

Very well, consensus is the PSU, so I will get a good one then. I'll consult the PSU tier thread and pick. Many thanks for your help everyone.

You will not make a bad choice by doing that, but you may not necessarily make the best choice, especially if you are looking for the best deal. If you do a little additional research on Tier 1-2 models, you'll likely make your best choice out of what is available to you.

Okay, so I brought evga GQ 850w, having fitted, I hoped for the best and gave it a go. No luck, it still freezes. Any other ideas? Could it be faulty? A new case to better cool it?

Motherboard bios is up to date just a thought sorry it was not the PSU

 

[Doccy_D]

BIOS is up to date so could it be a duff MB?

 

[burgessanthony]

COULD be GPU. you definitely have all the cables connected properly?

 

[Doccy_D]

Yes, all cables secured. So may try a lesser GPU to see if that works

 

[Doccy_D]

Okay, so I swapped the r9 390 aroind with a hd5700, and while it lasted longer before it freezes, it still does so. I guess it must be the motherboard then?

 

[burgessanthony]

CPU ruled out, GPU pretty much ruled out. I'd say RAM maybne

Do run memtest on your RAM, one stick at a time.
You did not waste your money on the new PSU, you just saved yourself some grief down the road.
Make sure your sound drivers are up to date too.

 

[Doccy_D]

Memtest returns no problems with RAM. After looking through this site concerning my MB and the freezing problem, I used the power options to lower the max power to the CPU to see if it would. I managed to play TW:Warhammer for 3 hours on the HD5700 for three hours without issue. I'm too tired now to try it with the R9 390. I will get back to you with what happened tomorrow.

Over the past few days my PC has run fine since I did the above. I thank everybody who posted for helping me with my problem.
