here's my magic formula:

-k phatk2 AGGRESSION=13 FASTLOOP VECTORS2 WORKSIZE=128 PLATFORM=1
Ati 5850
before:348 Mh/s
after:359 Mh/s

Saw an increase of 20MH/s, thanks.

What Mhash/s rates the 5830 users receiving on version 2011-08-27?

This version is a bit faster on 58XX cards, reports indicate it can be faster on 69XX cards, too ... I guess this is because of the optimized writing to the output buffer.
You can leave out the BFI_INT switch, but remember to supply the VECTORS2 switch

! This version takes care of wrong WORKSIZE arguments, too ... if you forget that switch, if it has an too big value or if it's not a power of 2, the maximum supported WORKSIZE for each device is used.

Thanks,

Thanks for this great kernel mod, it did result in a solid 7~ mhash increase on my 5570, up from 63~. Will donate some if I manage to get amazingly lucky solo mining (I figure it's more fun to try for freak luck, It's a better habbit than lotto tickets right?)

Can't seem to find it ,but I assume it had similar fixes to yours.

Anymore updates planned for the future Grin

.

Also I saw a 3% boost someone else was touting can I use that in conjunction with this?

Yes, there are updates planned, but it's really hard to squeeze more performance out of this. I'm currently testing a few different paths to achieve better performance!

Where have you seen a 3% tweak? Can you post a link here, so that I can check if this can be included (if it's not in already).

Thanks,
Dia

Strange: now I am getting the max speed with the original phatk2 included in Phoenix 1.6.2 with my 5750. Here the results of some tests:

phoenix-1.6.2 original
phatk VECTORS FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
=168 Mhs

phoenix-1.6.2 original
phatk2 VECTORS FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
=170 Mhs

phoenix-1.6.2 original
-k phatk2 VECTORS2 FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
=169 Mhs

2011-08-11 kernel
phatk VECTORS2 FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
= 165 Mhs

2011-08-11 kernel
phatk2 VECTORS2 FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
= 153 Mhs

phatk 2011-07-17 kernel
phatk VECTORS FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
=167 Mhs

poclbm VECTORS FASTLOOP=false AGGRESSION=7 WORKSIZE=256 BFI_INT
= 157 Mhs

Seems mixed up a bit

.

phatk = VECTORS2 (with my version)
phatk2 = VECTORS

Where do I find your kernel?

phatk2 has no VECTORS2 in Phoenix Wink

... you were not using my kernel either. Wrong forum?

Dia

I'm so confused Tongue

For some reason I thought you = phatk (and by extension phatk2). So your kernel is a modified version of the original phatk? Where do I find your kernel? And any flags you would recommend for a 6950? I'll report back with results

6950's using the new phoenix + phatk2 (clocked 880 gpu / 300 mem)

old: 360Mh/s
now: 364Mh/s

(consistent across all GPUs)

I messed a lot with flags... this is what gave me the highest numbers:

Code:

-k phatk2 VECTORS2 AGGRESSION=13 WORKSIZE=64 FASTLOOP=false

Not sure why, but worksize=64 is what gave me the biggest gain. Tried all aggression between 10 and 16 as well. 13 yielded the highest.

I tried it, and in my case, with a HD5870 at 990Mhz and 300MHz memory using the latest version of the kernel and Catalyst 11.5 + AMD Stream SDK 2.1 gives me 450MH / s.
With the flags-v-w 256-f0.
A good improvement.

Hmm... seem to be getting 4-5mh/s less for the latest release. This is on my stock 6950 with nothing unlocked using

Code:

-k phatk BFI_INT FASTLOOP DEVICE=0 VECTORS2 WORKSIZE=128 AGGRESSION=8

Also tried VECTORS VECTORS2 with no difference. I reverted back to the July kernel release for now.

Try FASTLOOP=false and perhaps a higher agression or WORKSIZE=256 ... SDK 2.5?

hey whenever I try copying the latest version into my kernels/phatk folder with phoenix 1.50 (also tested with 1.6.1) I get the following:

H:\Apps\Bitcoin\Phoenix>phoenix.exe -u http://user:[email protected]
:8337/ -k phatk VECTORS2 BFI_INT AGGRESSION=7 DEVICE=0

[15/08/2011 19:36:51] FATAL kernel error: Failed to load OpenCL kernel!

It works fine with the non-modified kernels...
Any ideas? =[
