I have run my crucial PC2700 fine at 202 mhz for awhile. @ either 2.5,3,3,11 or 2,5,2,2,11 one of the two hehe sorry it was awhile ago. vdimm was 2.8
The reason I don't have it that high now is cause it was only a 256mb stick. I have another stick of crucial PC2100 that I use to and I run it at 182mhz 2.5,2,2,11 also vdimm 2.8 I guess I could probably get a few more mhz if I relaxed the timings a little bit but I feel that I have gotten much more out of this stick that I bought for like 40 bucks 2 years ago than I should so I let it set there hehe.
