If the mobo is made for 4200 ddr2 533mhz ram would a 5400 ddr2 667Mhz work? Only reason i'm asking cuz i've found ram that is cheaper for the 5400 ddr2. Would it just slow the 5400 ddr2 to a 4200ddr2 cuz im ok with that.

i plane on taking my old ram out because it's 3200 ddr2 and i know my mobo supports upto 4200ddr2.
so by taking out my old ram and putting the 5400 ddr2 will it run at 4200 ddr2 or not work at all?

It's OCZ which i think is a pretty good company.
Memory Size: 2 x 1024MB
Memory Speed: 667MHz PC5400
Memory CAS Latency: 5-5-5-15
Memory Type: Dual Channel DDR2
Pins: 240
My mobo says DDR2 533MHz wid 240 pins. I'm not sure about the CAS Latency.

Cas Latency - CL2 or CL3 are the main things that will affect your ability to put faster ram into your machine. RAM will scale back to a slower speed if the motherboard only supports the slower speed. Just make sure the CL spec is fine with your motherboard and that the ram is of reputable brand. Kingston and Amicroe are top notch and my suggestions for achieving this.
Without seeing a pdf on your mainboard specs those figures should be fine. The ram would run at 533mhz instead of 667mhz, thats what is meant by scaling back - it drops speed to the maximum allowable by the motherboard. If you want to double check I suggest trying to find a memory compatability guide on your motherboard manufacturers website. Also as long as your cas latency timing is set to auto in your bios you shouldn't experience any problems.

It will work in the motherboard. Most likely it will slow it down to the 533Mhz speed, if you are lucky it will go ahead and run it at the 667Mhz speed. Either way, it is okay to buy it.

Go to wherever the mobo is being sold, such as the website, and look and see whether that RAM is compatible with the motherboard. It varies from board to board so that is the only thing anyone can tell you with the info you gave. Just check the motherboard specs and youll know.

Yes, in general, it's possible to use RAM faster than your computer supports, as long as nothing else about the RAM is different (for example, voltage or buffering).
If you're worried, then check your motherboard manual.
