4800 64 x2. I don't want to mess with the bios and hope wattage is not a problem. The 3500 chip is a ADA3500IAACN. I want to update with ADA4800IAA6CS. I have a 550w power source. On the Asus website both chips say : since bios 0103. On my startup screen it says I have revision 304. I want to confirm that this is all ok. Please help.
