Member: 8843 Status: Offline Thanks Meter: 117 | search the net and forum bro: AMD Radeon HD 6990 4GB Update - Overclocking Performance | PC Perspective video here: Unboxing: AMD RADEON HD 6990 4GB Video Card (Sapphire) - YouTube There are two BIOS chips on that card (for simplicity BIOS 1 and BIOS 2); one which you can over write and one you can not. Both can be over clocked, but the latter (BIOS 2) allows you to over write it to potentially unleash more performance as it does not have the built in limits that BIOS 1 does. The switch allows you to reset everything by reverting to the unchangeable BIOS. If you cant get MSI afterburner to work for you; then you should try TriXX that's another OC tool. |
