Yea with Crucial you shuld be able to hit at least 166 I would think. The more VDIMM you pump in the higher she will go. Also depending on what your temps are you should be alright at 2.85 VDIMM. You might damage it, but its the same with all OC'ing. There is always a chance of damaging a product if it is being run out of spec. However, from the cases I have seen people can put 2.85volts through it and run fine for an extended amount of time. It is good quality RAM, so I think you should be alright
