Different memory clocks in 2 HD 7770 GPUs

Hello all,
I acquired a 2nd 7770 for my system. This one has slightly higher clocks than the one I had before. The older one is HIS and the newer one is Gigabyte. Question is, can I set the new one at a higher memory clock than the old one. The HIS I run at 1075 GPU clock and 1250 Memory clock. The Gigabyte at 1075 GPU clock and 1350 Memory clock. It has been stable thus far. Is there any benefit/issue to doing this?
Many thanks

to run crossfire and for it to be stable you must have the same clock speeds on both cards. Downclock or overclock any of the cards to match the other.
