Hi,
I bought two MSI Twin Frozr IIIs 7950s for crossfire and while testing them both I noticed on stock volts of 0.993v card one can do 975MHz before errors appear in OCCT and card two does 925MHz. (These MSI cards ship 880MHz stock).
I have tested them both by applying more voltage and can do 1100MHz so no problems once overclocking with extra voltage, however is it normal to have such a difference between two identical cards? Do you think the worse card on stock volts can effect stability and overclocking potential when in crossfire with the better one?
I'm also thinking maybe card one isn't bad as such, it could just be my second card is a rare performing chip.
The main thing I want to know is are these differences normal between two cards?
Thanks
