So here's the deal: I wanted to increase my system RAM to the max allowed for my laptop which was 1GB (from 512MB), so I researched it, (the RAM I had already was PC2100 SODIMM 2x256MB), and ordered 2 bricks of 512MB PC2100 SODIMM. The new RAM was 266 mHz (and the Everest told me that the RAM I already had, was running at 133 mHz), and I figured that the speed increase was just the icing on the cake. So the new RAM arrived and I installed it without a problem. But as you can see from the specs, the new RAM is PC2700 and it only shows it's speed as 166 mhz (but it said on the chip 266 mHz). Since it works in my system, and things are definately faster, I'm not complaining. I would just like to know if the reason for the different speed is something to do with my mobo/cpu/fsb speed? And can this be tweaked (safely)? Or perhaps is the RAM faulty and I should send it back?
