Hello all,

I had to reimage my windows installation on my miner and when I got reaper running again I was only reaching speeds of 1675, before I was easily reaching 1800.  I am using the same settings and drivers and cannot figure it out.  Any suggestions?

Yes I believe I do, SDK comes packaged in the driver install right?  I saw it installed and I assumed it was the same.

Yep went back down to 1600 over night.  Is it supposed to do that?  Never had this problem...

Well, through tinkering with the gpu_thread_concurrency I get a average of 1750. Can't seem to get that last 50 again... Any suggestions/ settings you use? I tried cgminer but only avged 1500. Thanks
