Looks like it. I dont really know what that means.


That card probably has low ASIC quality to be giving HW errors at 1075 core.

Like I said in my last post, flash the BIOS and you should be able to reset the clocks on the other cards.
This exact thing happened to me after I upgraded to 12.4, but in my case, the cards were locked at 500 core.

From Slipbye (who is locked in the newbie section):

If you plug in your monitor into the gfx card thats only hashing at 50% then in CCC change the core clock up or down a couple mhz, just anything to make a change, hit Apply it should fix it. Do the same with the last Card again.

Not really 1075/685. No extra volts.

HW is hardware errors. Possibly OC too much?

I cant find AB 2.1.1 MSI doesnt list older versions on their site. Google searches just show me 2.2.

Also, i read your thread. You were having problems adjusting volts. I know how to enable unofficial overclocking mode. Thats not my problem. Two of my cards are hashing 300. The speeds are down clocked and cant be adjusted at all.






The one card at full speed has 31HW?

windows 7 x64
CCC 12.3
SDK 10.0.851.4

Try the SDK included with 12.3.  Should be 10.0.898.1

If you ever face any driver installation or post installation issues, try using ATIMan Uninstaller.  This will set your PC straight without needing to reinstall the OS.

I dealt with the same issue basically, you sure are going to be glad, hopefully.


https://bitcointalksearch.org/topic/help-lowering-voltage-on-a-7970-2-card-in-windows-7-32-bit-84709

Also I am using 12.3 and AB 2.1.1.   Uninstall everything, reboot then install the drivers then AB, then follow the process on the link above and you should be able to get them running.  I am getting like 1.4 G/Hash for two.

CCC 12.1 and 11.9 did nothing for me.

I picked up three 7970. One hashes at 650 the other two 300. Im using CGminer. I noticed my engine is at 500 and memory 150 for those two cards. Ive tried to change it with CGminer afterburner and CCC. No luck. Anybody know what the problem is?
