I'm planning to add some memory to a PC. The motherboard supports "DDR up

333 MHz (PC2700) or slower DDR SDRAM isn't easy to find on today's market,
and when you do find it, it's considerably more expensive than the DDR
which runs at 400 MHz (PC3200). What would happen if I bought 400 MHz DDR
RAM and installed it in a motherboard which only supports speeds up to 333
MHz (PC2700)? Would it work? If it did work, would it work as well as the
slower PC2700 RAM?

I've gotten conflicting answers to this question. Two computer stores told
me that it wouldn't work. Another store and a book I consulted said it
would.


I don't understand this. You went into stores asking?!!!! You
consulted books?!!!

This is such an obvious question to ask. Lots of people have asked it
on usenet.

Didn't you think to search usenet?

you're concerned about price and asking on the internet, and it didn't
occur, or you lacked the confidence, to buy on the internet?!

I'd also like some opinions on which brand of RAM I should get. Kingston
and Samsung are ubiquitous where I live, so the choice comes down to one
of those. Both brands are about the same price, with the Samsung being
marginally cheaper.


GOOD MAKES OF RAM
this is an obvious search. You can read books but you can't use
google?!!!!
Kingston and Crucial are good makes. I seem to recall somebody here
saying one wasn't so good, but they work for most people. Don't get a
bad or unknown or unlabelled make / unbranded ram.


Finally, would a 128 MB stick of 266 MHz DDR RAM be able to run in the
same computer as, say, a 512 MB stick of 400 MHz DDR RAM?


you mean at the same time?
i'd try it. it's unlikely that the mbrd wouldn't like it, and even
then, it's unlikely that it'd smoke out.

If so, would
using both at the same time degrade the performance of the faster RAM?


I vaguely recall that they'd run at the slower speed. .

You know about spam, so learn how to search usenet. Your behaviour
doesn't seem logical. What kind of justification do you have?!
