M17 Crossfire hd4850 issues Windows 7

ok i see maybe it is time for a paypal case but that is indeed a bad news i hope i will be able to revive the card ethier by flashing or by coocking

okay bad news the bios is not corrupted so the card is gonna go in the cooker this week end

 

UPDATE it's back and working it seem the bios was corrupted

and after the flash i just forgot to re enable the card in windows lol
also the wrong reading is from windows to when the card is disabeled windows block acces to it so the report in GPU-z are just plain wrong




back to testing i'm wondering how far down i can push the voltage on the slave seeing how with only 1 gpu the laptop could have 3.5 hours of batterie life i'm experimenting how far i can push my slave down so far i'm stable with the slave at 0.90v the master cannot get under 1.0 (maybe 0.98 but i haven't tested)

edit 2: master voltage down to 0.95 and slave to 0.8 i'm getting 1h20 with what is left of my batterie with a full one or even better with one repacked with those http://evva.en.alibaba.com/product/...ith_spot_welding_tab_Panasonic_NCR18650A.html considering that atm m17 pack are built with some really cheap 2150 mah cells
