New miner doe seem to have lowered the temp a bit but... I have lost probably .5% to 1% hashrate at max settings...
Clocking my 7950 at 1200 and 1800 with +20 nets just under 190MH/s. Previously it was steady at 197MH/s or better with the python implementation.
BUT... I would gladly trade that for NOT HAVING TO MANUALLY RENAME AND CHANGE AMDOCL.DLL EVERY TIME I WANT TO MINE SKC!!!!!!!!!
In other words... this worked perfectly on Win 7 64 GCN drivers. Boom goes da dynamite!
