I changed my host from a AMD7950 (too loud) to a 7970 last Friday, since then i have >95% Validate errors on opencl-ati 1.4.
ID 3781127: GHz, Win7-65, GPU 7970 @ 1 GHz, Catalyst 13.1, P55 with PCI-E 2.0 .
2-3 GPU tasks and 1-2 CPU tasks, about 275-290 VA from a 550W powersupply.
Yesterday i reinstalled the whole system (Win7+Boinc) , new ID is 6742381.
The first validate errors are coming again...
I can only see one "Validate error" on host #6742381. All the other errors are tasks that are deemed invalid when compared to the result from another volunteer.
the GPU-temp is between 68 and 75° C, the same as with my old GTX460 for the last two years. Fan speed @ 47%, GPU utilisation abt. 88% with two tasks.
I start to see validate errors when the gpu HS get dirty and card starts to run hotter than normal. I also got alot when I added too much gpu for the PSU to deal with.
Linux Memtest is ok, stresstest with Prime95 shows no errors, even flashed a new BIOS...
I'm puzzled.
There is one think that points to a bad power-supply: after upgrading to HD7970 >95% of the wu's fail.
The new card needs more power. One thing you could do is to exchange the PS between 2 pc's; that's not too much work to do.
If that fails, you could exchange ram-chips.
Has your PS 2 6-pin power-connectors for the graphic card or is it done with these adapters from the older 4-pin disc-drive power cables?
You could install the TRIXX-utility from AMD, this gives information about the card's input voltage, this should not be less than 11.7 volts.
my Enermax "EPR525 AW" PS has 3 "6+2" connectors for PCI-E.
The Host draws about 275VA (Conrad Energy Monitor) with Einstein (2GPU+2CPU tasks). Milkyway uses ca. 330 VA with almost no errors, so i think there is enough power+ headroom available.
GPU Voltage is 1.175V.
Thanks for all suggestions. And excuse my english.

Is the card overheating? Is it overclocked?

Hi Holmis,
the GPU-temp is between 68 and 75° C, the same as with my old GTX460 for the last two years. Fan speed @ 47%, GPU utilisation abt. 88% with two tasks.
The 7970 runs at 1GHz, not overclocked.
I will try some Milkyway-WUs later.

Minor update:
My Tasks on Milkyway:
Status: Alle (261) | In Bearbeitung (0) | Ausstehend (17) | Gültig (236) | Ungültig (8) | Fehler (0)
No dust, gpu-temp is below 70°C, also downclocked the gpu to 925 Mhz(from 1000), tested with 0 to 2 cpu-tasks, but no joy with opencl-ati.
Linux Memtest is ok, stresstest with Prime95 shows no errors, even flashed a new BIOS...
