Went from ~402mhash at 950/300 on a 5870 to ~417 with this (SDK 2.4) Tweaked the memory clock up a bit to 350 and now it's more like 418-420. Definitely a nice improvement ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Very nice! I'm getting almost 10 Mh/s more than with the poclbm kernel on my Sapphire Xtreme 5850. Thanks Phateus.

Unfortunately no improvement on a 5770: @935/300 -k poclbm: 207.5 @935/300 -k phatk: 202.5 Higher memory clocks only decrease performance more. Might be because I'm running SDK 2.1, do you think it would make up for the ~5% loss going to 2.4?
Same results here on my 5770 - nothing changed really. @960/300 -k poclbm: 213.4 @960/275 -k poclbm: 214.1 @960/300 -k phatk: 212.8 @960/275 -k phatk: 212.2

I get the following error message when I try to run phatk: File "./phoenix.py", line 123, in <module> miner.start(options) File "/home/elrock/phoenix-1.47/Miner.py", line 74, in start self.kernel = self.options.makeKernel(KernelInterface(self)) File "./phoenix.py", line 112, in makeKernel self.kernel = kernelModule.MiningKernel(requester) File "kernels/phatk/__init__.py", line 126, in __init__ platforms = cl.get_platforms() pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code
I think this may have something to do with the fact that my GPU is DEVICE 1 and not 0. (For some reason OpenCL recognizes my CPU as DEVICE 0.) ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)

This modified kernel kicks ass. Went from 350 to 371 with stock 5970 (850 Mhz - it's the slightly overclocked 4 gb vram one) speeds and aggression level 7. With aggression level 12 performance bumps up to 377. All the memory is at 300 Mhz. Very nice! Thank you so much OP!!!! ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

I can verify this. My power usage went up too. From 412 to 421 on one rig to 440~ Now the question is whether the extra hash power justifies the extra power consumption..math anyone?

I can verify this. My power usage went up too. From 412 to 421 on one rig to 440~ Now the question is whether the extra hash power justifies the extra power consumption..math anyone? Ok, According the deepbit's reward calculator, 405MH/s gives .097 and 420MH/s gives 0.10 BTC per hour Switching gains you .003BTC per hour or at the current exchange rate of $7 per: $0.021/hthe difference in power is 15 Watts ( .015 kW) The price of electricity is about $0.10/kWh ( http://www.eia.doe.gov/cneaf/electricity/epm/table5_6_b.html) The cost of electricity from the increase is .015 kW * $0.10/kWh = .0015$/hSo... the increase in profits is 14 times higher than the increase in cost. Unless the price drops to .5 or the dificulty goes up 14-fold, pretty much any overclocking / optimizing is worth it. Edit: Also, the increase in air conditioning will likely double the cost of electricity, but the cost is still is negligible compared to the increase in profit. Hope this helps ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) -Phateus

Running a single saphire 5850 at 875,900 overclock with ati sdk 2.4
using the poslbm kernel - 328 MHash using the phatk kernel - 340 MHash!
Very nice!!! I'll be sure to donate!

My dual 5870 (w/o CF bridges) maxes out at WORKSIZE=128. Nope, that too maxes out at 256. What I said was 768 simply is not valid for 5xxx hardware. Phoenix should output the error OpenCL is returning instead of covering it up.
