With same memory and cooling, there should not be.

However, some testing recently make me think that those cards could maybe
hit power wall and crash not because of memory OC, but because of power consumption.
Previously I thought GPU consumes much more than memory, but on these low GPU power cards,
memory actually consumes big part, probably even more than core...so I would definitely not
dual mine on them...either use algoritm that taxes memory, or one that taxes GPU, but not both



Bought one of those powermeters from ebay, its on its way from China, if noone answers before, I will in a few days
