well the story is like this : I own a X800 Pro card on PCI-E platform from Palit the card is built on R430 chipset instead of 420 as usual what pops up in mind first is WOW I have 16 pipelines open... but no only 12. I assumed I could have turned this card into X800XL for the following reasons: 1. Same core (R430 hope the other 4 pipelines r good and not corrupted just locked !) 2. Same Memory !!! same samsung Chips (took off the heatsink and made sure of it ) 3.the card can hold up with XL speeds (400/500) actually it does (472/520) I've downloaded a "XL" bios non-VIVO card as mine ! assuming it will fit cause Sapphire build all the XL cards. than got into dos backuped the old bios and typed as following: a:\ATIFLASH -newbios -f -p 0 bios.bin than got the faulty result: OLD SSID : 554f NEW SSID : 0600 OLD P/N : X800PRO-256MB NEW P/N : 113-AA45300-101 ERROR 0FL01 what did I do wrong? I am despert!!!
