Crucial 2100 2.5 needs more juice ?

I was told that I need to up my voltage to atleast 2.9V to get my crucial PC2100 moving.Right now I have a soltek SL-75DVR2 board that only lets me go to 2.7V .Is it time for a voltage mod or is it better left alone?

Well, I run two sticks, normally, just at 2.5V, you need more juice if you're pushing the FSB up too much on them, though

Thats odd that you would need more than 2.7v? what kind of memory and what fsb are you trying to reach?
