Yap you got it right, the bottom one is the decent one.
I had so much fun with it and it promised so much that I decided to go crossfire with them... learned my lesson.
Even tho its a crap picture you can see the quality difference in both boards.
The voltage in the crap/more recent HD6850 is locked in everything except Sapphire Trixx, but Trixx has troubles accessing it if it is the secondary card, needs to be the main card.
Most of the stuff that I say about my pair of HD6850 might not make sense, I admit it. But it's what happens...
The crap card has to be the main card else crossfire won't work properly nor will my PCIe slots give 16x speed, I tested the PCIe slots alone and they work fine.
With ulps disabled I can't overvolt the recent card if it is working as a slave card, it need's to be the main card else my pc will shutdown everytime I change voltages and everytime I stress them with any kind of overclock, I did that with 790Mhz, 15Mhz above the stock core...
Any1 wanna buy it from me?

I had it at 1Ghz with 1.3v but the temperatures would become an issue since the stock cooler couldn't handle it, so I played it safe with 920/1150 at stock voltage.
Was expecting of reaching arround the same values when I decided to crossfire but far from that, the crap card has its own will.Edited by Tokkan - 10/31/12 at 7:12am
