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.

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.

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.

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!

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.

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.

Using absolute newest DiabloMiner? What hardware and what arguments?
I believe I'm using -v 1 -w 256  (on a 7970)

Those seem to be the correct arguments, so just make sure you're on the newest build. The loss of 25 mhash seems odd.

I need use -na on command line. Without -na i having 35 Mhash/S !!!!! using latest diablominer on 12.2pre with 7970 !!! LOL !

Adding -na to -v 1 -w 256 now gives me normal 677Mhash/S

Uh, yes. You need -na on before 12.2 due to a bug in the driver. You don't need it unless you suffer from the bug because it makes it slower.

Hmmm, I guess I didn't verify to see if I had downloaded the newest build (I know it's fairly new, but I guess I don't know if it's the newest)  Smiley

Incidentally, is it possible to pass out different arguments to different cards on the same machine?    In case I find a cheap card to throw in addition to my existing. Smiley

Not yet. You need to run multiple DMs at that point and use -D to select them (like, one 7970 and two 58xx? -D 1 on the first one, -D 2,3 on the second one).

Fudge.  I accidentally upgrade to what appears to be 12.3, and I lost 25 MH/s Sad
