Do not use. Not able to overclock anything (shows as 0 core and 0 memory).

@ssateneth
windows or linux ??

No mining change from 12.2  Can still overclock fine, CPU usage still low, mhash unchanged.

This is on a single 6970 on windows 7 64 bit, using clocktweak and diablominer.

I have the same problem with this version that first came up with 12.2. When using cgminer 2.3.1-2, SDK 2.1 and phatk kernel on a 5870, my hashrate is normal, but the miner never submits any shares. Downgrading to 12.1 helps.

Same. I was wondering why my 2.1 sdk wouldnt submit shares but 2.6 would.

Also windows.

Im using the 12.3 WHQL driver, still able to underclock memory to 200 Mhz (optimal speed), Core Clock is now at 1020 Mhz

hashing away at 457 Mhash/s on my single 6970 using vectors (77 degrees Celsius for temperature)

Also I'm using full release OpenCL 1.2 driver, but the only difference I noticed is more stability. Used to have my core clock at 1015 Mhz

What hashrates is everyone else getting that are so bad with new drivers?

I get zero because I refuse to use any sdk other than 2.1

I'm now using the 12.3 LLQL (Linux Low Quality Labs) release and it's satisfactory on my 6970s and 7970. The 7970 on linux would crash at lower than normal clock speeds with the 12.2 release but that problem has gone away with 12.3.

[juhakall]

If the new drivers continue to have problems with SDK 2.1, I guess it's time to move on and use the SDK bundled with the drivers + diablo kernel. That gives me about 98% of the hashrate compared to SDK 2.1.

It's worth noting that I spent a lot of time customising the poclbm kernel in cgminer as well so that it works well with sdk 2.6, and of course cgminer has a diablo kernel option as well.

An a diakgcn option as well (use with -k diakgcn -v2 -w 256) .

The other thing is that sdk 2.4/2.5 should actually work fine and they're very close in performance to 2.1 anyway.

I take it back. It is slightly less stable with 12.3 than with the 8.921 driver release. I randomly get a GPU disappearing with 12.3 that doesn't reappear after a spontaneous reboot, but its fan keeps spinning.

[ssateneth]

Thing is, if it ain't broken, don't fix it. Why would I ever "upgrade" to a dodgy driver/SDK if the ones I use now are proven to be the fastest and most reliable of all? The latest isn't always the greatest. 11.12/12.1 and 2.1 forevah.

[DeathAndTaxes]

I agree. Most of the changes to drivers has to do with gaming functionality, improved compatibility with new games, and new feature bug fixes (tesselation, hydravision, etc).  

Until we reach a point that
a) existing drivers/SDK either can't be used anymore (most likel)
b) offer better performance
c) offer improved stability
d) offer more features (expanded under/overclocking & under/overvolting, etc)

I don't see a reason to upgrade downgrade.

[-ck]

The fact is that the existing drivers -were- broken. It did not properly set up my mixed 7970/6970 rig and I had to put them a specific order on the motherboard to work, and to manually add devices to the xorg conf. So these problems should go away on moving from the preview release driver to 12.3. Furthermore, there were rumours of a very slight increase in hashrate going to 12.3. However, it introduced other problems as you've seen me say. But since I now have a working stable machine, I ain't changing it for shit unless there's a much more compelling reason.
