Man all these small time newbie miners start coming out of the woodwork...  Grin




I thought you lost the lease for your place and were selling off your cards?  Or am I confusing you with somebody else?

Ok.  so most of my farm i have 5 or 6 cards to each rig.  (gd70's, 5870's, 5850,s etc).


last year i started building out the 7970 rigs with 5 cards.. no problem with the beta driver: (amd_radeon_hd7900_win7_64)


now i have purchased some new 7950's.  they dont hash as fast with the older drivers (~30% less).

as soon as i install any driver 12.1 or newer, only 4 of the cards will load the drivers.  windows and msiafterburner sees all 5 cards, but only 4 will load drivers.  wtf?

anyone else experience this?  
any help would be appreciated .. bounty!
