Re: RAM upgrading problems
It's true that they are different speeds. It could be that your computer doesn't support DDR 400 (unlikely). It could be a bad stick of DDR 400- which is most likely the case. The beep codes, will also tell you what the problem is- check your manual and see if it lists them. If you can't find it there- check the Web site of the motherboard- it should tell you. We know that RAM is a problem, we just are not sure if it doesn't support it, or if it's bad- the beep codes should tell.
