Different core speed on Crossfire

[thegamecpt]

If I use two XFX 6850 that have different core clock and memory speed on Crossfire

1. Core Clock: 800MHz
Memory Clock: 1050MHz

2. Core Clock: 775MHz
Memory Clock: 1000MHz

Will they both run at 775, 1000? or run at indepent speed?

If Crossfire works anything like SLI, they'll both run at their separate factory speeds unless you clock them together, which you probably should do.
