So, people have been asking about where all those donations for a 7970 went, and when was I going to get my 7970.

Good news: HOLY GODDAMNED SHIT IS THAT FAST
Bad news: I think I'm going to play Portal 2 again. And Half Life 2. And a few other things. I'll be back in a few years, I promise.

About time...

OpenCL 1.2 is out too. Running it now, same speed as before it seems like.

http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx

You do realize all that is is an API specification, right? 2.6 was shipping with very beta 1.2 support. 12.2 ships with something slightly newer than 2.6. Do not install an SDK on top of 12.2 for optimum performance.

12.2 is about the worst driver amd has a released in a while. Running the 8.96 driver that comes in that package (12.4). Works pretty well.

Yeah but Linux doesn't have anything newer yet. Although, I gotta admit, I like how my 2.6-ized kernel is performing. 555 mhash at 925mhz. The troublesome part is, I'm going to have to look for new ways of optimizing this, I've tried a bunch of different things that greatly effected performance (both positively and negatively) on the old compilers for vliw5 and vliw4 and it is doing absolutely nothing on the GCN compiler (which is great, mind you, it means the GCN compiler is actually working right).

I am going to be disappointed if all I get is 555 at 925. I wanted over 600.

That developer driver was horrible for both of my 7xxx setups.  Constant freezing and BSODs.

Went back to 8.95.5.

Yeah, you should never use RCs or preview or whatever versions. Only use the standard releases, which happens to be at the moment 12.2 on both Windows and Linux.

No problem to report, just giving some data.

I finally bought a 7970 for my gaming/mining hybrid rig, and been running solid for the last few days, only shutting down the miner briefly while gaming.

mhash: 622.4/622.1 | accept: 11715 | reject: 8 | hw error: 0

12.2 drivers, nothing funny installed just a normal driver install minus the cat control center.
Using MSI afterburner latest beta, clocktweak doesn't seem to work with the 7970.
Voltage 1031 Core 1050Mhz Mem 710Mhz
Fan at 66%, but my card is the new dual fan sapphire which is nearly silent at that level*.
60-62C


Very happy.  Not the cheapest source for it's level of mhash, but for my gaming PC where I don't want to deal with crossfire and I just want a strong single GPU it's perfect.

*Nearly silent as in I can't hear it over my CPU fan... it's not truly silent though and if my CPU was water cooled the GPU fans would be very noticeable.

Good stuff!
Now you just need to open that card up a bit and let it run!
Crank the core to around 1175, leave the mem at 710, bump the voltage to ~1.15v and it'll give you right at 700 Mh/s.
Mine's water cooled, so watch the temps and drop it a bit if it gets up towards 80c.
Enjoy!

Your overclock settings might be (partially) be rejected, 7970s won't let you underclock memory more than 150mhz below the core speed. Double check and make sure its actually ay 710, its probably not. Other than that, you should be getting about 630 mhash @ 1050mhz. Make sure you're using -v 1 -w 256 without -na, and that you're using 12.2 with 12.2's OpenCL runtime (its newer than what SDK 2.6 ships, do not install 2.6 on top of 12.2).

How do you check the real mem speeds, something like GPU-Z accurate?

I'm using those exact settings and driver/runtime.  If my memory really is underclocked to 710 that would explain the ~8mhash difference, right?  If that isn't it, I'll have to check my diablominer version, I thought I had the latest but maybe I missed an update.

Not sure, GPU-Z should displaying actual instead of set, but I don't use Windows. On Linux, aticonfig --odgc does show the difference (Current clocks shows actual, current peak shows requested).

Memory speed doesn't seem to matter with hashrate on GCN, it just drives the temp up. For me, 1125/1375 -> 1125/975 drops the temp 3-4c.

You can't underclock mem less than -150 unless you use unofficial overclocking or some other trick.
Mine is running at 710, same as chiro.

AB, beta 15 in OC mode 2 lets you to set memory all the way down to 685.
GPU-Z displays that on the sensors page, cgminer runs with it.

Does voltage control work in b15?
I'm on b14 and it doesn't work on my 7970.
Unwinder (author of AB) said he's not focusing AMD chips for now, he's moving on to Kepler...

BTW, 921 driver is way more stable for OC of 7970s.

What's 921 driver?
I'm running the 8.96 driver from 2/28/12.

Driver Packaging Version   8.921-111202a-129903E-ATI

Downloaded from AMD site: 12-1_vista_win7_64_dd_ccc
Not only more stable, but I get higher MH rates.  Same settings.

Oh, that one. I can't run that. Since i've installed a newer one, it won't let me go back for some reason.
I've even tried driversweeper, ATIMON, and other 'deep' uninstallers. Nothing seems to work.
12.2 is the oldest release that I can run, and even that one won't work right for me.
It may have something to do with the fact that I have an nvidia card on the same machine?
Anyway, it's working for now, and I'm hashing at 712 Mh/s, so I'm nnot gonna screw with it. Smiley

What kind of settings are people using for 7970? I'm running my gpu 925MHz/366MHz for testing purposes.

Latest DiabloMiner "-v 1 -w 256" mining at ~550MH/s
Phoenix 1.7.5 "-k poclbm WORKSIZE=64 VECTORS3 AGGRESSION=14" mining at 552MH/s

I'm using the 8.95.5 driver set.

555 mhash is the estimate for 7970 at 925mhz at the recommended settings of -v 1 -w 256. So you're about right.

12.3 whql drivers just released.  8.951 display driver.  Doesn't seem to be any change in mhash for the 6970 rig I am testing now, compared to 12.2.

I'm using those exact settings and driver/runtime.  If my memory really is underclocked to 710 that would explain the ~8mhash difference, right?  If that isn't it, I'll have to check my diablominer version, I thought I had the latest but maybe I missed an update.

I checked in GPU-Z and can confirm I really am getting mem down to 710.  Also, putting mem back up to 1425mhz and I see the mhash go up slightly to 629, possible 630 if I gave it longer to stabilize.  I don't think the 8 mhash difference is worth the extra heat of running full speed mem, though.

As far as clocking higher, I've had it up to 1212mhz which gave 720mhash, but with the stock cooler and my current insufficient case cooling, temperature rose above 80C before the driver crashed.  At 1188 I get 703mhash and this seems stable, but again temperatures get into the scary high range after awhile.  I like to keep at or barely above 60C (without running the fan at 70% +), and with those limitations around 1050mhz is my limit.

I've been using MSI Afterburner 2.2.0 beta 14 with the "UnofficialOverclockingMode   = 2" added to cfg, I guess I should have mentioned that.

12.3 is now out on Linux.

Seems to be half an mhash faster if at all, hard to tell. Low 675 to high 675 instead of high 674 to low 675.

Hi guys, need a little help here.

I just got my second mining rig up and (kinda) running, but I'm having some troubles.

When I try to run Diablo, I get the following messages:
 "Using AMD parallel processing OpenCL 1.1 AMD-App (851.4)
error: OpenCL platform AMD parallel processing OpenCL contains no devices
error: No OpenCL devices found
Diablominer: An error occurred while starting the application.

I'm running 12.3 catalyst on XP Pro SP3, and everything looks fine on the desktop side.
It seems like there's no SDK installed, but I tried installing it manually and there's no difference.
Thoughts?
