I'm running the puddinpop rpcminer-opencl.exe that came with Guiminer. I'm running it with crazy settings -gpugrid=128 -gputhreads=256 -aggression=14 on a FirePro 2270 workstation card, and it's reporting about 20 GH/s which I understand is not even remotely possible. I assume something went wrong and all my hashes are broken somehow, but how do I troubleshoot this?
Update: The same miner works fine on one of my other machines. I did find this output on the console:
Build program rval=0 build STATUS: build LOG:C:\Users\Sean\AppData\Local\Temp\OCLF1AC.tmp.cl(51): warning: attribute "vec_type_hint" ignored __kernel __attribute__((vec_type_hint(uint))) WORKGROUP void opencl_process(__global opencl_in *in, __global opencl_out *out, const uint loops, const uint bits) ^ Create kernel rval=0 Done allocating OpenCL resources for (128,256) Finding best configuration step end (128,256) 6ms prev best=9223372036854775807ms Done allocating OpenCL resources for (16,16)
So the warning is odd, but also that last extra (16,16) line doesn't show up on my other machine that works.
Update 2: With "crazy" settings I get no shares. If I run with no options, it reports 10 MH/s and seems to get about one share every 10 minutes. So somehow changing the settings makes it generate no shares at all!
