Went from 380 to 391 on my 5870 @900MHz.

Nice work!

is it possible this doesnt work on nVidia cards? both with OpenCL miner & CUDA miner i'm still getting the exact same hashrate, even after restarting Guiminer.

or am i missing something? (using windows 7 btw)

Sorry, this only works for ATI cards that support BFI_INT. In general, nVidia cards are much worse for mining, so I'm not sure if there's effort at all going into making nVidia's stuff mine faster...

Dude, awesome  Smiley so this accounts for 3% out of your 6.4% improvement, where are the other 3.4% coming from? I don't have 250 btc, in fact I only have ~2 that have been donated to me so far. (Please note - if you decide to share this, post it,don't pm me Smiley)

I think I deserve the right to keep this remaining ~3% a secret of mine. I have contributed a lot to this community. AFAIK I was the...

Now all the miners are using BFI_INT; shops are selling pre-modified PCIe extenders; etc. Enjoy :-)

Yeah i know Nvidia cards aren't too good for mining, but i was hoping for a slight increase... oh well Smiley

Thanks for pointing it out tho, much appreciated Smiley

Sure, of course you do, dude! It was just a joke Smiley sorry! By the way, I absolutely love your blog - I've read it a lot, just didn't know it was yours.

I tried using Phoenix, but my GPU isn't recognized. Neither with phatk.

I'm running Arch Linux with an Ati Radeon HD4650. DiabloMiner detects my GPU, and I installed AMDStream, so that isn't the problem.

I did this with phatk in phoenix-1.50 and I got a 2.4% increase on both my 5870 and my 5770. Thanks!

Getting some good results, but one out of 7 workers always locks up after some minutes. GPU usage goes down to zero, shown MHash rate stays locked at last value, cursor is still flashing. Occurs only when the cards are overclocked, but the same and even higher OC values work flawless without this fix.

If I was of any help, donations are appreciated - 1FrCtiQsVoy2YTTYqgjsvVvdgvHS4Umah4

Anyone tried this using guiminer?  I can see the file but not sure if I just edit the portion:

// Ma can also be implemented in terms of BFI_INT...
   #define Ma(x, y, z) amd_bytealign((y), (x | z), (z & x))

Contemplating the powers of BitCoin.

Hy all, I'm new here and pretty new with this bitcoin thing.

I tried to modify phatk kernel as explained and I was able to speed up my mining as all of you.

Really don't know when and how this amd_bytealign function is called, anyway I think it should be better to write it as follows

#define Ma(x, y, z) amd_bytealign(((z) ^ (x)), (y), (x))

That said, I took a look at the rest of the phatk kernel and found what seems to be a sintax error. In my file it's on line 74:

#define r1(x) ((rot(x],15)^rot(x,13)^((x)>>10U)))

Mmmm... that poor and lonely square bracket... rewrite it as follows

#define r1(x) ((rot(x,15)^rot(x,13)^((x)>>10U)))

These modifications did not speed up my mining power but it seems that my rejecteds almost halved.

If this helps you as well, donations are obviously welcome Wink
