AGP voltage and increase in GPU core voltage is indeed NOT the same thing:)

if you want to know if your card is flash-able I advice you to take great care in taking a proper backup of your original .rom and also have a PCI vidcard ready in case the flash does not work, so you can still boot the system and restore the original one.

you might want to surf around a bit more on google and other forums asking if anybody with R9800 with infineon memory has succesfully flashed their card and what bios they used for that

since these guys host almost all vidcard bios's known to man, their forums might prove interesting: http://www.mvktech.net/component/opt...ard/Itemid,34/
