I am trying to change the memory straps for the Pitcairn cards. I think that some of the 370s which feature the high quality Samsung memory can benefit from a lower strap used on a higher clock rate. Basically what we did for the 470/480 where we took the 1500Mhz strap and used it for the 2000Mhz.
So far there are no bios editors for these entry level cards. You have to do everything by hex editing. So far using the MSI 370 ROM bios I see that it features the following straps.

So far there are no bios editors for these entry level cards. You have to do everything by hex editing. So far using the MSI 370 ROM bios I see that it features the following straps.
