Well I can't seem to use these drivers with my 6000 series cards plugged in at the same time Undecided

. It's either or for now Tongue

I'm running 6000 series and one 7970 on ubuntu 11.04 and the shitty 8.921 driver. It involved manually editing xorg.conf, not sexy :/ Also cannot change voltage and seriously downclock memory.

Please share if you had better progress, thanks!

Spent hours sorting it out. Made a lot more progress:

@jjiimm -- I hear you on the PSU's - -Seasonic Golds FTW!

But my questions wasn't answered, can you run it off a x1 or must it be x16?

Aha, it works only if the 7970 is in the first PCIE slot (plus I manually edited xorg.conf).

Pick the 7970 amongst these (mining solo for testing):

Code:

 GPU 0:  74.0C 4312RPM | 685.5/686.7Mh/s | A:0 R:0 HW:0 U:0.00/m I: 9
 GPU 1:  74.5C 5362RPM | 427.9/428.5Mh/s | A:0 R:0 HW:0 U:0.00/m I: 9
 GPU 2:  73.5C 4627RPM | 428.0/428.7Mh/s | A:0 R:0 HW:0 U:0.00/m I: 9
 GPU 3:  73.0C 4197RPM | 437.2/437.4Mh/s | A:0 R:0 HW:0 U:0.00/m I: 9

Does anyone think it possible to run one off a x1 slot?

Trying to avoid the cost of an MB with 4x x16 slots...

IMO

cheap cpu: OK
cheap mem: OK
cheap mobo: NOT OK
cheap psu: NOT OK

the mobo and psu will outlive the cards you put on it... dont skimp on the PSU or MOBO

Can you use kill-a-Wat , and tell my whats the wattege of your rig ?
Whats the hash rate ?
have you checked "atitweak" tool ??

I`m considering buying 7970, but ATM only windows can handle them right, witch is BAD :/

Yeah, all 4 are running properly under Ubuntu 11.10 64-bit.

I ran into the CPU bug, but that was fixed by exporting GPU_USE_SYNC_OBJECTS=1

I'm getting hosed on power usage though because I can't bring the memclock down further than core - 150mhz (I was wrong on my previous post). Can't change voltage either. The cards behave like the 6000 series (as far as clock/voltage adjustment goes). This could be easily fixed with a BIOS flash, but there aren't any BIOS editors yet that support them(that I know of). The newest version of atiflash supports flashing them though.

You checked all 4 cards in linux ??
Any performance issue ??

Fixed by using 64 bit. I'll bet there's a problem with 32 bit being able to address all 12GB of video memory (3GB per card).

Finally got a chance to try this out. I tried it last week, but the driver kept hanging during boot. I thought it was my crummy flash drive install I was using (long story) but just did a clean install on a spare hard drive. Same result with 4 cards -- black screen + hang. Plugging in only 1 card boots though.

The damn Core - 125Mhz memory limit thing still exists... Fuuuuuuuuuu. It's worse now though -- it seems to be set to stock core - 125Mhz. The current core clock doesn't matter.

I don't see anything about it anywhere, but I just went to download drivers for another rig and noticed that these just got listed today. Grab 'em while they're hot:
