I had 2x256mb Corsair pc2400 that could run at 195fsb (2.5-4-4-11) and would score 2600/2400 on Sandra mem test...also, no errors on memtest...I wanted a gig of memory w/out spending a lot of money so I got one stick of OCZ Premier...btw, by itself it could run at 228fsb (2.5-3-3-11)! Since it was with the Corsair however I had to run it at 195fsb...then I decided that I had such good luck with the first stick of OCZ that I'd get another but out of the two I've tried I can't get it above 214fsb (2.5-4-4-11) without Memtest errors...I must have gotten lucky with the first stick...with the 2 OCZs my Sandra was 3000/2800...anyway, after doing the math I found that it would cost me $50 more to keep the 2 sticks of OCZ (and sell the Corsair) than to just keep 1 stick of OCZ and run it with the Corsair...I guess my ? after all this is if the +20fsb is worth $50 to you people (if you were in my situation)...btw, I paid $195 (after tax) for the 2 sticks of OCZ...
