Gigabyte GTX970 G1 MemtestG80 errors

Hi All,

So just ran MemTestG80 on my GTX970 that although reasonably stable at stock speeds has given me a couple of driver crashes in CSGO (and has not really given me much of a stable overclock at all) and have got lots of errors (several hundred thousand during a 256mb scan over 100 iterations).

Now I've not used MemtestG80 before, so have no idea if it's as certain a result as memtest is for RAM.

I've tested the card both on my x58 and x79 boards, and have had consistent results on both. Is this an RMA?

Any advice appreciated!

Never mind... Just did some googling and seems like the number of errors I'm getting is actually quite low :-)

Guess its not a very useful bit of software!

Any other thoughts for a more accurate stability check? I'm having inconsistent results between Valley, 3d matrk 11 and 3d mark firestrike with this card. Valley is rock solid even with a reasonably high overclock, 3d mark 11 sometimes throws an error, sometime runs fine. And firestrike runs the first sequence fine, then just sticks on a black screen at the end (i think some sort of bug when trying to move on to the next test).

So all in all definitely having some mixed experiences with this card, this was one of a pair and the other one has had to be RMA'd already as it was definitely faulty (not stable at stock speeds at all).

Any thoughts?

Hi all,

Should also mention I've not actually water cooled either of these cards yet. Haven't felt comfortable with the stability whilst testing on air (plus been waiting for my back plates to arrive from EK).

I have been wondering if some of the issues are just a ropey driver? The latest driver has certainly been more stable on this card than the previous one.

Thanks,

Sounds like immature drivers to me?

Are to able to revert to older drivers which are 100 percent stable?

Did you say you got errors on memtest or not?

Try Heaven 3.0
 
Hi There,

That's what I'm hoping. Older driver might not help as its a fairly new GPU. All I can say is that the current drivers are definitely much more stable than the last series (including the one provided on disc with the cards).

I'll have a bash at heaven and see what that gives me. Just really dubious about slapping the water blocks on until I'm happy there isn't a hardware issue with the card. Having one failure has just made me a little paranoid I guess....
 
Oh, and only get errors in memtestG80 (200,000 or so...). System is rock solid otherwise and had been running as is for about 18 months with a pair of 660tis no problem. SO haven't run normal memtest or anything.
 
One 970 will run CS:GO fine at max settings so why not try one card at a time?. If it happens with them both running on their own then it might point to a slightly unstable CPU clock. Only reason I'm saying it might be CPU instability is that CS:GO is CPU intensive and will push your CPU more than GPU.

So if both cards separately do not crash then maybe save your current overclock in a profile in your BIOS and revert to default settings and test again?. Do not rule out a different GPU driver unless you have already tried this. I've had to revert with Nvidia drivers due to crashing in BF4. As Nvidia are usually rock solid it was the last thing I tried. Even went through my overclock again from scratch and wasted a whole day messing around.
 
Thanks for the reply.

Sorry should have mentioned that I've been running the cards separately anyway. Going to be water cooling them as the slots I'm using are too close really to run them on air (various issues where the other slot is an issue with my case and water cooling). Tried them both at first but had blue screens either due to heat or more likely because of the one card that is definitely not happy and has been rma'd.

Also ran them on two different boards and cup setups. Might double check if I've tested on stock settings though as both rigs are fairly heavily overclocked so worth a try.

I've been playing advanced warfare on stock settings on the Gfx card and it's been pretty rock solid. Even happy with a reasonable overclock, but once playing csgo anything other than stock causes the issue pretty regularly.

I think I'll just keep running it on air for now and continue testing. Don't really want to strip my loop down and rebuild a second time when my replacement card arrives. Rather have both cards and do it the once. My cpu's loving having 5x120 rad worth of cooling for the time being though ;-)
 
i have driver crashes green screen in csgo aswell i updated drivers hope it helps .

as in benches heaven and other games it is fine strange , maybe because it is not demanding game and boost speeds go up and down voltage can't keep up or something.
