okay, so looking at PBE when it opens my original BIOS for these cards it appears that there are 2 type of memory on the card, one is:
K4G80325FB (SAMSUNG)
the other is
H5GQ8H24MJ (HYNIX_2)
Do you have straps for these memory types that are "better" than PBE's built in ones?
You can physically have only 1 type... Yeah I do have better.
For the Samsung go with Uber-mix, it's free and very good.
