PC2400 DDR on a 800FSB system

[Demitre]

Hi, I just bought a p4 2.8 800fsb system with 256DDR 400mhz memory.

I have a stick of 512MB pc2400 on my old system. Would I create a huge bottleneck on my system putting in the old memory?

bad idea, the other memory will clock down and rul slower.

OTOH, 256MB is not much. If you run any games, you might benefit more from extra memory than from the higher clock speed. Just an idea.

If your 256mb's is (2x128) dual channel, I wouldn't use the old memory. If not, then I would add-in the old memory and see if you notice any difference. If your 256mb is a single stick, you might try to get an exact match and run in dual channel mode.
