Title: Radeon 6950 loss of hashrate after driver update! Post by: lechuck on June 29, 2011, 05:21:23 PM my ati catalylst driver offered me to update today so I did.
after the update , my hashrate went down by almost 60Mh/s! im using a sapphire radeon 6950 flex 2gb with the -v and -w 128 flags in GUIminer under wind7. before the update i had around 310Mh/s, not its only 240Mh/s - and all that changed is the driver version. besides that there were only a few windows update installed, but that all that has changed since yesterday when i still hab 310mhs im using deepbit for pool mining. anyone else having this issue? any idea what I can do to get my lost Mh/s back?
