Title: 7970 Linux drivers released
Post by: sveetsnelda on January 31, 2012, 01:24:30 AM
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:

has anyone tried cgminer with the new drivers?

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.

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).

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

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.

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 :/

Well I can't seem to use these drivers with my 6000 series cards plugged in at the same time :-\. It's either or for now  :P

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

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

@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?

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:
