Differing speed of RAM cards

[Guest Gnarlodious]

I installed a 512 RAM card some time ago and XP ran real good. Now a

computer tech who I am not sure I trust as found the card and blamed

it for a software registration error. He removed the 512 card

(actually a DDR 400mhz) and explained that it is the "wrong speed and

not recognized by Windows". He says even though the numbers on the

System Control Panel match the RAM Windows still ignores it. This

sounds bogus to me, is he lying? Do RAM cards need to be matched in

speed? I would rather upgrade to faster rather than use the old slow

cards.

 

Thanks.

I would find another tech if your don't trust him/her.

Unless your motherboard specifically requires "matched pairs" of memory it will use the card.

But if you have two card with different speeds, you machine will work at the slower of the two

speeds, not the faster card speed.

Yes, Windows usually needs all RAM to be the same even if the motherboard

doesn't.
