oh my god I have tried like 4 times now to revert to 2.5 sdk and i cant revert! I've tried uninstalling -everything- amd related and used driver sweeper every time too, but i simply cant revert it! its like it just decides to keep the most recent sdk "just in case".

\

Same here... and it didnt solve the cpu bug for me.

it is slower with phoenix but it has small boost with cgminer with flag -I 9(to remove cpu bug)

w7 x64 5870@950/300 gives 434,4Mhash/s, with catalyst 11.11/b/c/ was 433,3

One mega hash from One user...
Anyone else got something on the positive side for these drivers?

It's very likely that nobody will see improvements until kernels get rewritten to better accommodate the new version of opencl and AMD APP.

Dual boot linux ... ok how many bitcoins? Tongue

/nope.

not touching linux.

Anyways it felt like forever, but I was able to revert to 2.5 SDK. Bitcoin offer is no longer valid. If you're using windows, simply replace these files with those of 2.5 SDK and you should have your faster mhash back

C:\Windows\System32\amdocl64.dll
C:\Windows\System32\amdoclcl64.dll
C:\Windows\System32\OpenCL.dll
C:\Windows\SysWOW64\amdocl.dll
C:\Windows\SysWOW64\amdoclcl.dll
C:\Windows\SysWOW64\OpenCL.dll

I also uploaded a rar file with these dlls if anyone needs them to revert. http://dl.dropbox.com/u/9768004/AMD-APP-SDK-v2.5.rar
just extract it to the drive you have your OS installed on and it'll extract each file to the correct path.
edit: forgot link.

thx for this detailed infos...

the "old" performance is back again Grin

i'll pay bitcoins to someone who can help revert without needing a complete system format.

When I installed 11.12, I noticed the opencl version was hugely different. it went from 2.5.793.1 to 10.0.831.4. opencl is probably a completely different beast now.

Yeah, I noticed this aswell, I was actually JUST about to update all my drivers on my gaming rigs to play battlefield 3, Hearing that "12.1 will probly finally use all of your GPU in BF3"
But seeing this performance drop aint worth the headache...

Anyone got info on that part?
Running crossfire 6870's 1ghz core each, 11.11b (seems the best as far as i know) and battlefield 3 with:
2xAA
1920x1080
Shadow=High
Texture=High
Postprocss=Off
Motion blur=Off
Everything else, Ultra.

And yet i get a Steady Solid 45fps, That only drops to <30 when i fly and look over the Whole Map
It feels Correct, There doesnt FEEL like and performance is going to waste, it FEELS like it's just NOT being asked to get used
Like fucking shit i can mine with -f80 and my fps doesnt drop too much
And i'll get about 80mhash/sec percard!!!!

With 58% load on both cards.......................................................
I WANT TO TURN MY SETTINGS UP THANK YOU VERY MUCH!

edit: huge mhash drop. asus 5870 / sapphire 5870 / sapphire 5830 xtreme went from 475/501.8/317.1 to 440.1/454.5/286. DO NOT INSTALL!!!!!!!!!
edit2: maybe you can update to 11.12 driver but stay on "old" opencl. i'll post back with results.
another: I didnt even check to see if cpu bug was still there with 3 vid cards. sorry guys
zzz: after uninstalling, rebooting, driver sweeper all amd products, rebooting again, installing 11.11, I still have the "new" opencl somehow. my good miner has been tainted!

from 11.11 to 11.12

plus:
first time multi-gpu-cpu-bug solved in 11.12 - for me
installed on 2 x 6990-rig

but

minus:
hashrate dropped ~5 %

12.1 is only preview and seems to have the performance of 11.12

With both 11.12 and 12.1 I went from 310Mh to 270Mh on 3x 5380's clocked at 950/300, AMD x4 w/ Win7 64x.

I'm using 2x 5850, but i don't think there was a hashrate drop. MAYBE 10 mh/s drop, max.

Previously I had a 5830 running at 272 Mhs with Phoenix 1.7 Phatk2 128worksize on Cat 11.11

Now getting 250 Mhs with the same settings.

Ouch.

Anyone esle try the preview? Going to try installing the old Opencl Package from 11.11 ontop of 12.1

(I was able to bring it back up to 265 Mhs with the original Phatk kernel, but still not as nice as 272....)
