I have INTEL 845 GVSR motherboard and intel 2.4 GHz processor. and 512 MB 333 MHz RAM. My motherboard support RAM upto speed 333 MHz and I want to install a 400 MHz 512 MB RAM with it(because 333 MHz RAMs are not easily available in market nowadays). Will my motherboard support 400 MHz RAM? Do two RAMs of different speeds not work? What should I do. Go to www.crucial.com and input your motherboard info and find out RATHER than guess.

Go to www.crucal.com and nput your motherboard nfo and fnd out rather than guess.

That mobo is the same one I had that came with my old Dell Dimension 2400.

I had one stick of 512mb PC3200 and one of 256mb PC2700 in the computer (I purchased the 3200 without realizing it wasn't 2700 because some mook had been shuffling thru the RAM sticks for sale on the shelves of Office Max and I picked up the wrong one and didn't know it until after I got home)

I plugged it in and it worked just fine but I noticed the faster stick clocked down to par with the slow stick. This meant I had 768mb of RAM, but they were only clocking at like 266 mhz or somewhere in that region

This didn't really degrade the computer's performace at all; it got better by far since it just got 512 more megs of RAM.. but if they would have both clocked at the intended speed it would have been better

I hope this helps you, like I said I had the same motherboard, and the PC3200 worked for me.. You could see if Newegg or Fry's has anything around that kind.
