Looks to be the same PCB but with solder masking over certain areas(I'm assuming the bottom card is the new one)
As far as I can tell, they have the same layout and components, jsut one has solder covered pads and the other has masking over those pads.
Yep, and PCB is physically thicker a bit, VRM doesn't have any coil whine, even @ 1.3 V, and some surface-mounted bit are slightly revised.
slightly better ASIC quality compared to my other card(which does 1300 MHz pretty easily), and slightly lower clocking ability.
At least it's stable.
Also decided to use a second Crossfire bridge, and that seems to fix some of the flicker I was getting in 3DMark...or it was the fresh driver install I did. Either way, quite happy now, since I can now get the review done on my last Z77 board, the ASRock Z77 Extreme11!!!!
