Does my 7850 have the 7870 PCB?

I see that it has another space where the 2nd (7870 has 2 6-pin connector slots) 6pin slot should've been. Can you also tell me what power phase it uses please?

BIG PIC

You see, there on the bottom, those holes.

Yes, the 7850 uses the 7870 PCB. Both are based on the same Pitcairn chip. However, the 7850 has a few disabled units and is slower than the 7870.
As for power phases, the 7870 is 5+1+1, the 7850 is 4+1+1.

It's cheaper to do one board layout and just stuff it differently for different products when possible. It's a good way to save some money.

Thanks.

So that means It can take as much voltage as 7870? I mean the vrms and the other things. My 7850 has 1.038v stock and 7870 has like 1.1-1.2v stock. Would it be ok running at 1.2-1.225v in games?
