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.
Hey man, can you list down cards with Samsung memory and their memory type code on which you've tested the UberMix straps and get excellent results. I've only had the Asus Dual OC 580 and the ubermix strap is just plain garbage on it. I know i'm not alone as i've seen lots of comments from miners saying UberMix strap is shit anyway.
So let's put names to the cards where UberMix shines as you say.
