7990 on it's way out?

Footyslayer · 27 Sep 2014 at 16:28

Hi everyone, I'm after some expert advice here.

I bought an MSI 7990 from here about on the 24th August last year. Over the last 2 weeks I've had my screen randomly crash whilst sat idle, crashed when booting and the biggest problem is that BF4 has become unplayable, I don't play it anywhere near ultra even though it can handle that.

BF4 has become laggy and my FPS when on the move drops to 35fps and rarely gets above 60-70fps now. With this amongst other things is the card on it's way out? I do also have ULPS off on MSI afterburner

*EDIT*

The card only gets to 68c so is not overheating!

Is it overclocked?

Have you tried unistalling the drivers with DDU and reinstalling?

Footyslayer · 27 Sep 2014 at 16:38

Never had it overclocked. I have undervolted it to save heat from 1200 to 1150 and has been fine for a year, I've even tried putting it back to 1200 to no avail.

Not tried the drivers yet, would it be that though even though it's been fine all this time?

Its something to try, sometimes drivers can become corrupted.

In the ops sig, Corsair TX750W like mine so definitely good enough.

Footyslayer · 27 Sep 2014 at 18:34

Yeah, had the PSU for as long as the gfx card and all fine till now.

I've done a complete clean of the drivers, as clean as it can get. Re-installed the newest beta drivers and the same problem persists.

I get about 5-10mins of solid high FPS and then it becomes damn near unplayable!

Using Mantle?
Does it do the same thing in other games?

Mal X · 27 Sep 2014 at 20:08

it's either the card or the PSU is loosing power....more likely that the card is dieing slowly

CAT-THE-FIFTH · 27 Sep 2014 at 20:13

Don't rule out PSU problems either - get your voltmeter out and do some tests!

Using mantle and DirectX. i've noticed an occasional glitch in FIFA 14 and 15 but nothing too bad.

I lean towards the card, don't a lot of 7990's get an issue after about a year? I've read of a few issues on here.

Erm, don't have one

Sounds like Crossfire is not working, what does it say in GPUZ ?

What am I looking for exactly?

Mal X · 27 Sep 2014 at 23:30

go to AMD Catalyst and check that Crossfire is selected, it's also in MSI too, but this wont be the cause if the pc has been degenerating slowly over time..............check for Viruses/malware

it sounds like either the PSU or the Card is packing up over time, your worry is that the 7990 is loosing power and therefore isn't running hot, because even with undervolting, it should still be about 85 to 92 degrees :eek:

750W is a bit low for a 7990, it should be 1000w, so maybe your Corsair is starting to pack up instead.

gareth170 · 28 Sep 2014 at 01:06

a clean install of windows may fix it, or check to see whats running in the background.

i had similar issue, and it turned out to be the msi afterburner OSD that was slowing it down.

Crossfire deffo seems to be enabled. Yeah the 7990 was running at about 85c until I invested in a corsair air 540 case and replaced the fans with even better ones, also the custom fan curve I have keeps the heat down so I don't think that is a reflection of anything.

Tried closing background apps, didn't help. I will try tomorrow with afterburner turned off whilst gaming but again I'd find it odd for this to happen now after all this time!

You sure it is 7990 causing the crashes?

If it crashes on idle, it could well be your CPU overclock that you thought was stable ain't really stable afterall? Try bringing your CPU back down to stock clock and see if the crashes remains.

Footyslayer · 28 Sep 2014 at 12:58

It's only done it on idle once but I thought it was odd at the time and since then I have had the performance issue's whilst gaming.

Also the overclock was done by overclockers themselves, I bought an overclocked bundle and this has also been fine for over a year. should I contact them?

Threepwood · 28 Sep 2014 at 13:06

It's not your 2D clocks/volts that need stabilizing is it?

Combat squirrel · 28 Sep 2014 at 13:10

My old cards did this, it was a faulty PSU faltering in supplying clean power, the card crashed, defo check your PSU
