I know some tricks that should make a 3%-5% speed change; and another 1-2% with settings. I am getting 290 m/hash with 945 GPU clock (Ati 6870). The changes can be done by anyone; you don't need to be a computer programmer or anything; so bare with me; It works with all cards;

Changes:

You want to go to folder Guiminer/kernels/phatk;
should see a file called kernel.cl; open it with notepad;

change code;

define Ma(x, y, z) amd_bytealign((y), (x | z), (z & x))
and change it to this line
  #define Ma(x, y, z) amd_bytealign( (z^x), (y), (x) )
Once you've done it, restart the miner.

That should give a 3% speed boost;
For another change; in extra flag in the guiminer
Put;

This section is best for ATI 6870 Note;
--------------------------------------
-k phatk platform=0 device=0 VECTORS BFI_INT AGGRESSION=13 worksize=128 FASTLOOP=false

For other cards use;
https://en.bitcoin.it/wiki/Mining_hardware_comparison go here for other models.

Let me know how it works xD

For me giving tips on 3% speed change please donate to
