Just send it to me or the hardware if you don't require it anymore.

Lol,That new member is a scammer if you look at the 4 posts all say the same.Hopefully,no one actually sent him the .1.

BTW,I did do V2 but my 6950 doesn't seem to like that as the results are still a bit lower than Phateus' variant.I get 352-356.6 with your latest variant but with Phateus I get 353.2-358.4 at the same clocks 867/1250 clock.

^^ Catalyst driver 11.6B/SDK 2.5 -V 4 -w64 -F3 using GUI miner

I'm pretty sure 4-component Vectors are not helpful for 69XX, please try -V 2 or VECTORS2.

I've tested your patch, and there are some great improvements from the original phoenix 1.50 miner indeed.
My 6950 gets improvement.
My 5870 gets improvement.
My 5850 gets improvement.

But I have noticed a regression with my 6870 (1005mhz core / 200 mhz mem)

Configuration:
-Using window 7
-Using Catalyst 11.6
-Using the aoclbf 1.74 frontend for phoenix 1.50
phatk
Vector
BFI_INT
Aggression 13
Work size 128

2011-07-03 kernel: 317 mhash/s (all 3 number are peak value)
2011-07-06 kernel: 283
2011-07-07 kernel: 283

...Needless to say, something bad happened between 07-03 and 07-06. I hope we can get to the bottom of this. If you need me to test something, I will be happy to do what I can for you.

The latest version need the argument VECTORS2 in order to use 2-component Vectors + try to raise your mem clock. There was a version, who needed a little more MHz for the memory to be efficient. Please report back!

Use the default posted on page one for that 5770 and you should see almost a 10% gain.

Speed decrease by 2-3.5 Mh/s on my 6950 but .5-.8 increase for my 5770.Stale/Invalid rate seems to be higher over @BTCGuild as well.....but not Deepbit.Got mixed results on this one.

That decrease for 6950 is weird and it should NOT be like this ... whats your Phoenix comand line, driver and SDK version?

Is it also possible to update the latest OpenCL driver, for example ATI SDK, before the program starts ?

Why dont you add such feauture before improving speeds ?

No that's not possible ... you have to make sure you use current drivers.

As an addition to my post above, I have tried to test the new kernel in Windows as well, using guiminer/phoenix. When replacing the default kernel.cl and __init__.py with the ones from kernel 8/11/11 followed by creating a new miner I get the following:

Code:

2011-08-12 07:44:40: Running command: C:\guiminer-20110701\guiminer\phoenix.exe -u http://user:pass@pool:8332 PLATFORM=0 DEVICE=0 -k phatk BFI_INT VECTORS2 FASTLOOP=false WORKLOAD=128 AGGRESSION=11
2011-08-12 07:44:40: Listener for "testdiapolo" started
2011-08-12 07:44:41: Listener for "testdiapolo": [12/08/2011 07:44:41] FATAL kernel error: Failed to load OpenCL kernel!

As a further test I put back the original kernel.cl and __init__.py, and the test miner works fine with them.

What is WORKLOAD=128? This should be WORKSIZE=128!

My 5870 went from 436 to 398.

VECTORS2?

Thanks, I knew I was missing something. I'm at 451 now.

I did a short test with the latest kernel and it seems the ALUBusy value of 68,9% is way too low. Only 68% of GPU time is used for ALU instruction processing. The ALUPacking of 98,5% is nearly ideal.
