1700 cpm at 2x R9280!
Great work!  :)

i think we can do more than 2000 with 2x R9280  :((
Why of course you can. Welcome to pts.1gh.com :)

Re: OpenCL GPU miner by girino for ypool.net - edit: new Release, 10% faster

I just released another windows binary with new optimizations in the hashing code. This version is about 10% faster than the previous one.

Links on the first post of this thread. (new file is jhProtominer-win64-mingw-build4.zip).

Please update and test.

tested : 2x R9 290x  with -m512 / -m1024 or -m2048
The result is the same :

how strange. Does it happen also with the other algorithms? (command line options: "-a gpuv3" and "-a gpuv4") .

With old jhProtominer-win64-mingw-build2 i had the problem, that after running smooth for 1-2 hours, monitor goes black and computer freezes. No chance but to reset whole machine. (One of the mining-gpu is also for monitor). This happened 3 times. Hopefully jhProtominer-win64-mingw-build4 has fixed this, i will report later...

Realy great work! ~1000 cpm on 7970 with gpuv6 and 1024 mb of memory ( with 2048 work slow ~300 cpm)
thanks!

Problem seems to be fixed! No more crashes for >6h.
2070 cpm with 2x 9280x @1080/1500MHz, -m1028  :D

Helo all,

I just released new binaries (ending with build5) in the same old place (see first post). Those binaries use a new sha512 code, tuned and optimized by my during the last few days. It is at least 15% faster than the old code.

Short Version: faster! gpuv7 is default, gpuv9 is the low memory mode.

TLDR version: The new "-a" options "gpuv7", "gpuv8" and "gpuv9" all use the new code. "gpuv9" is the low memory version, same as "gpuv3", using the new sha512 code. "gpuv8" is the same as "gpuv4" with the new code, and "gpuv7" is based on "gpuv6", but uses a linear collision avoidance hashtable instead of the plain hashtable used before. It is bound to find slightly more hashes at the cost of being a little bit slower. since in all my tests it produces better CPM, i made "gpuv7" the default mode. The old modes are still kept for compatibility (maybe my optimizations are not compatible with all GPUs, then you can always fall back to the old modes).

Please download and enjoy.

Thanks,
girino.

girino, can you implement gpuv7 to beeeer miner? thanks
