I am finding blocks with 40MHASH. on my test rig. with spreadminer #14 and the latest driver.

Run it in benchmarkmode, if your oc is to high, you will get cpu validation errors. The netowrk difficulty has doubled and so has the price. As the price falls abit, the difficulty is falling as well..

Spreadminer opensource, and spreadminer sp-mod < 12 doesn't work with the latest driver. You have to use 382.xx or older.
