If the 5770 to 6770 works my bet is the 5750 can be flashed to 6750 as they use the same core as well,make sure memory is the same first as that could be what stops it

Too bad I didn't know this a year ago when you could still buy 5770's. I got two of these and then discovered they could be unlocked!

It's a damn good card though. I have two 6770's in CrossFire as well as a PNY 8800GT for PhysX! Let me tell you, it's beautiful! I run Alice 2 and Batman: Arkham Asylum & City on max settings+physx on 60fps (my monitor doesn't go higher) :) Only works in some games though, it's these and Cryostasis and possibly a few more. Some people have been said to unlock Crysis 1 to use hardware GPU PhysX, but I think they hardcoded it to use CPU cores in stead. Maybe someone went reverse engineering on it and hacked it. Crysis 2 does not seem unlockable. And nVidia has disabled this hack in the most recent drivers. 0621 is the last one that works. I can provide BIOS dump as well. (Edit: For Sapphire 6770 GDDR5 1GB. This is not the Vapor edition.)

the hd 6750 and hd 6770 are just rebranded hd 5750/5770. same gpu, same drivers, same bios, same performance, so it's not surprising you can flash the cards. i wouldn't call it "unlocking" because you dont unlock anything, bios flashing doesnt change the sticker on the card to "hd 6770"

6770/5770

Does't the 6770 utilize twice as many ROP's? Yes, they are the same card otherwise. 6770 performs better than a unlocked 5770 because 5770 only uses 8 right ?

Huh

Huh indeed. But yay, that does make me happier since it means these are good cards already :) They weren't that expensive (compared to higher models like 6990) but a *very* welcome upgrade from my Radeon 2600's. These cards are 10x faster.
