2378-FVU memory question

[wolfman]

Hello all, I'm considering purchasing this laptop and have a problem. I'd like to use the 2 512 meg sticks of PC2100 that I already have in my R40 machine. I *believe* the 2378-FVU uses the 855PM chipset which supports PC2100 and PC2700. IBM ships the unit with a stick of PC2700. My question is if I remove that stick of PC2700 and replace it with my two sticks of PC2100, the BIOS will adjust the memory bus to PC2100 speed and all will be OK? Thanks!!!

Yeah, it will adjust.

i dont see why you would want to do that though...youll be loosing speed. sell your 2100 sticks, shell out a little extra dough and get 2700 sticks.

Ther reason was mostly that I read a post here a few weeks ago where there was a T40 and T41 with the same amount of ram, same processor and same hard disk and the benchmark results for PC2700 versus PC2100 were only between 2-4% different. I didn't feel that amount of increase was worth the trouble, however, if other users experience a bigger performance difference I might be worth it.

I would think that pc2100 (266mhz) vs pc2700 (333mhz) would make a bigger difference because it would limit your fsb from fetching memory as fast,

but the more I think about it I could understand why you wouldn't gain as much due to the 400Mhz fsb of the Pentium M chips. I think it would make a bigger difference in a system that had a higher fsb.

Any links to the memeory speed review?

Here is the link I remembered from a few weeks ago - just found it again now:
