DDR2 ram help........?

hi there. i have bought a 2GB ram stick from cex online, and it stated that it was DDR2 @400MHz. however it does not work in my computer and after running CPUZ, it said the ram was 200MHz. also, i had tried to put it into a DDR computer and it would not fit, the groove in the middle was just slightly off.

after re searching i could not find such a DDR2 PC3200 ram... however i have found some links of amazon

http://www.amazon.com/ACP-EP-Memory-400MHZ-PC2-320...

http://www.amazon.com/Kingston-Memory-240-pin-PC2-...

http://www.amazon.com/Kingston-ValueRAM-240-pin-PC...

CPUZ stated it was CP2-3200, where it was stated it was PC3200 when i bought it. does such a DDR2 ram exist ? can someone please help, thank you.

    What you have is a 400 MHz, DDR2 (PC2-3200) memory module. That's the slowest DDR2 module made, and was never very popular, since the plain old DDR (PC-3200) memory performed just as fast, and was cheaper.

    As for the 200 vs 400 question, DDR stands for Double Data Rate, so it doubles the clock speed (200 to 400 MHz). CPU-Z is reporting that correctly.

    Sounds like your computer just doesn't like memory that slow - or can't handle the 2GB module (some motherboards could only take 1 GB sticks)

    the RAM will fit in the other computer, you just need to turn it around. The groove was slightly off because you had it backwards. Chances are it was running at 200mhz because either A: Your motherboard only supported up to 200, or B: You had another stick in there that was 200mhz, in which case they will both run at the slower speed or C: you need to go into your BIOS and up the maximum speed.

    ddr 2 ram does exist but you need to look inside the computer itself to see weather the motherboard supports it just open its case and look next to the RAM bay it should say ddr ii (ddr2) or ddr i (ddr 1) that gives you an insight as to what your looking for there is a difference between the RAM types:

    DDR 1 RAM looks like this

    DDR 2 RAM looks like this

    if the RAM is runing at 200 MHZ its most likely ddr 1 or ddr RAM not DRR 2
