Re:BFG 6800GT SLI overclocking - 2005/03/24 14:21
This is because of the PCI-Express HSI bridge. The overclocking headroom on NVIDIA PCI-Express cards are going to be limited as compaired to the AGP counterpart. No one should expect any model of the NV45 to run better at clock speeds of an AGP card. The stuttering is because your card is throttling back as well as who knows what else. To get rid of the stuttering set the clocks at 445/1100 or below, adding voltage does not help either. The majority of NV45 simply does not have the headroom at those speeds, unless of couse if your lucky and received an exceptional card with the choicest chipset but even then the HSI is going to cause some issues, so dont run the card that far out of spec's. Also the NV45 is fragile to sustained overclocking, so beware.
