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. Dia |

Make sure you back up your wallet regularly! Unlike a bank account, nobody can help you if you lose access to your BTC.

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? Dia |

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

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! Dia |

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

You got my application ... Dia 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. |

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:password@192.168.1.77:8337/ -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? =[ |

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

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.

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: -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. |

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  |

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
