So, because some blame me here is my full config for this computer
Windows 8.1 64
core I5
16gb ram
ATI 14.6
3 R9 290X in the computer (not oc)
Config that works :
gpuPlotGenerator.exe plots myaccountid 68847637 18500000 4096 256
9400 nonces minutes
gpuPlotGenerator.exe plots myaccountid 68847637 18500000 4096 128
14500 nonces minutes
gpuPlotGenerator.exe plots myaccountid 68847637 18500000 4096 64
14500 Nonces minutes
I have 1 R9 290 & 4 R9 270x
I Put 32 in thread & 1000 in stagger size
It generate 30000 nonce per minute, but all of my cards don't work!!! (GPU Core Clock,GPU Memory Clock and Temp are very low)
Is the plot useful?
