Topic: Sign of 5970 failure? - page 2. (Read 2506 times)

Something is off, was only getting 13fps with the default 1080 preset in that app. I didn't see a way to see more specifics with that app.

So after going from driver 12.3 (originally working fine) went to 12.4 (no good at all, opencl didn't detect cards), now went to 11.10. Now with same config hit with the cpu bug (cgminer 2.4) and 3 out of 4 gpu's are fine. No issue with cpu on 12.3 driver so I am back on that.

I'm convinced it is the card for now. I will look for another app that may be able to detect what specifically might be wrong, that app did show poor performance but that's it.
I'm going to run it for rest of month as is in the crippled capacity until I shutdown operations for summer.  With power price jumping to .19/kwh too much even for downclocking in my opinion.

Test the card with Furmark or something. I do suspect its the gpu or vram going bad, but I wouldnt use bitcoin benchmarks to get an RMA.

I have a Win7 rig with a couple Diamond 5970's that have been cranking away for months, no problems at all. Both cards run about 380 Mh/sec per core clocked at 830 core and 300 memory at stock voltage, stable for months.

Now without any changes 1 of the gpu cores looks to be having an issue: With the above clocks it was jumping all over between 550-830Mhz, gpu load cutting in and out. I back the clock down to 820/300 and it is cranking away but load is fluctuating between 90-96% (previously pegged at 99%), 64c temp, fan is fine but it is only generating 304Mh just on this core. At present after a cold boot the speed quit fluctuating and it is stable at 820/300 as per GPUZ but lost its gusto for some reason. Other core on this card is completely normal.

I tried changing clocks back to stock at 725/1000 and when starting a new mining session it will still not hit full load.
Running at 725/1000 a core is making 304 Mh/sec is that typical for stock? When overclocked to 820/300 GPUZ would report that speed and I would still only get 304 Mh/sec. Has anyone seen something like this?

Power supply is Rosewill 1300 Lightning, powering only these 2 cards.

I bought the card on ebay and have sales receipt from previous owner and registered the card. It is refurb but should still be under warranty. In this case if I try to send it back would they even have a card to send me to replace this? I can imagine if they did find one laying around it would take months to get a working card back.

Based on the above info would you consider the card bad and would Diamond agree?

Thanks in advance for any feedback

Edit: Now it looks like another GPU is doing the same thing, so narrowing down to either whole card going, or power supply. In cgminer I have gpu 0-3. And 0 and 2 are now problematic, are these the same card? And the clocks on this new problematic core are jumping all over the place and the core as listed in the OP is stable at 725/1000. So the card could have a power issue or something with VRM's?
