Hi @ll,
first I want to say CGMINER is a fantastic app and I really appreciate all the work and time in it. I already donated
One thing I notices since version 1.5 (when I started to use it)..
I have a 4xHD5830 Windows x64 rig with clocks at 960@300 and had in the beginning constant hashrates around 315MHash or more.
Over time, with new CGMINER versions, never kernels and for sure updated drivers/app sdk the performance is lower and lower.
Currently with 12.1 driver and APP SDK 2.5 I only get around 280Mhash with poclbm and worksize 128 (I8) (tried many settings and different kernels and this works out best).
I am wondering what may be the issue here? What settings do you currently use for best performance and what driver-app sdk combination.
Any recommendations would be nice. (Remember Windows OS please.)
Thanks!!
