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:

Title: Re: 7970 Linux drivers released Post by: sveetsnelda on February 04, 2012, 04:43:42 AM 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. Title: Re: 7970 Linux drivers released Post by: sveetsnelda on February 04, 2012, 07:15:58 AM 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).
Title: Re: 7970 Linux drivers released Post by: ummas on February 04, 2012, 07:57:23 AM You checked all 4 cards in linux ??
Any performance issue ?? Title: Re: 7970 Linux drivers released Post by: sveetsnelda on February 04, 2012, 08:01:56 AM 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. Title: Re: 7970 Linux drivers released Post by: ummas on February 04, 2012, 08:27:09 AM 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 :/ Title: Re: 7970 Linux drivers released Post by: -ck on February 08, 2012, 02:16:23 PM 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
Title: Re: 7970 Linux drivers released Post by: JWU42 on February 08, 2012, 03:11:03 PM Does anyone think it possible to run one off a x1 slot?
Trying to avoid the cost of an MB with 4x x16 slots...

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 Title: Re: 7970 Linux drivers released Post by: -ck on February 08, 2012, 03:38:27 PM 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 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 Title: Re: 7970 Linux drivers released Post by: jjiimm_64 on February 08, 2012, 03:41:27 PM (plus I manually edited xorg.conf). ouch.... the only thing i do to that file is usually delete it and reboot :) Title: Re: 7970 Linux drivers released Post by: JWU42 on February 08, 2012, 11:47:26 PM @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? Title: Re: 7970 Linux drivers released Post by: Prattler on February 09, 2012, 08:16:02 AM 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 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!
