All was well until Ive been playing Far Cry, and several times now the card has reset itself. Am I to assume that the card wont run safely at that speed, in which case Id need to revert back to the original bios? I did try this earlier, however upon running atiflash Im told 'Adapter 0 not found'. The fan is notably noisier now also, which I guess is to be expected. Any help/advice on this would be great.
Marcus ... Alot of the VIVO cards could not run the XT PE speeds without a voltmod. Try one of the XT BIOS with the 500/500 speeds... or use a BIOS editor and set the speeds to something the card can handle.
