So far working awesome, my fps has improved per the ingame FPS reader, (i.e. WOW and BF3) Catalyst does read 1050 mhz clock and 1500mhz memory.
I'm really happy with it. I'm definately tempted to get a second gpu and flashing it. haha.

Do you have voltage control?

I was getting memory out of range errors(BSOD) after playing BF3 for 3 hours plus since I flashed this bios over a week ago, flicked the switch back to default bios 3 days ago, no BSOD so far and I have put in two 5 hour sessions of BF3.

 

Is there just one version of the bios or is there more than one ?

I just upgraded, and loving it. I haven't gamed at all, just installed and ran 3dmark11 and tried a 1200mhz OC. Passed with less voltage than before. I dunno if it's the 12.7 driver or not but I like it. GPU score higher with less of and OC. Before 1225 gave me a GPU of 10038, now 1200mhz gave me 10,123, with 1.15v instead of the previous 1.25v needed. I still have to game a bit to see how stable it is. Oh and stock 1050mhz runs on 1.093v, however I don't know what the stock values before BIOS upgrade were. i don't remember.

EDIT* that 1200core voltage wasn't gamable, but the stock was. And provided good FPS in Skyrim

My original bios was running 925/1375 @ 1.17v load. With the ghz bios, it runs at 1050/1500 @ 1.24v load. What do u guys think about the voltage? It's a little to high for my taste, not sure if it's safe.

different programs are picking up different load voltages. OpenHW monitor shows 1.256v for me but GPU-z shows 1.08-1.15 and actually fluctuates like it should, so id go with gpu-z over whatever you are using.

Yeah those numbers are from gpu-z and I thought they were a little high as I game daily.

Just an update, bumped the core to 1.2v and its bf3 stable. I'll probably run that as my daily oc. Its still less than the previous 1.25v needed
