...... 12.1 Drivers, what are release day RC drivers ??? 


Thats your problem. 12.1 does not support 7970s. You need the AMD drivers release for 7.XXX. The problem is its now the brave world of OpenCL, and to get the 7970 running OpenCL apps, you need the drivers they released when 7970s were released. Those drivers do not support CAL, as CAL is officially dead. So the new drivers are native OpenCL written for the new GCN architecture of 7970s. Without them, and running 12.1, the card just sits and cycles doing nothing because its looking for OpenCL support and can only see CAL which it doesnt understand - or doesnt seem to. DNETC have a CAL app nearly running on a 7970, but I'm not convinced they will finally do it ... see what happens ..

Guru3D are carrying them, these are the next version after the release day set - its an RC - Release Candidate - set, but they work fine

Load those up, and you should be fine. I copied my app_info below just in case:

<app_info>
<app>
<name>milkyway</name>
</app>
<file_info>
<name>milkyway_separation_0.82_windows_x86_64__cuda_opencl.exe</name>
<executable />
</file_info>

In case you have not yet realised - Validator is borked at present, so when you get to the test stage, may well be a delay geting validated results. Usually they are validated in seconds, but at present the Validator queue is choked up.

Could you please lock this thread Blurf?

Opened a 79XX Dont Run II now that the 7970 mad rush is over (as such)

IBTL :-)

...on a serious note though, i'm going to keep this thread on my list of subscriptions just in case i need to reference it down the road. this thread has lots of good information...

*EDIT* - oops, didn't realize they merged the old thread with the new until now...

Apols if this has been covered and I've missed it, but there are different voltage bins of the 7970.

This explains my issues in post way back where I was running CCC AMD based overclock and it was happy with 1125/+20 - then I installed Trixx, changed nothing (looked to ensure voltage was on the minimum trixx would do) - but the temps/fan jumped up and wouldn't come back!!

Also there will be XP support for 7970 in future:

This thread seems to be a little old, but is this still relevant to the 7970? I'm running into problems crunching with mine in my new system currently.
