How could I know PC3200 DDR400 RAM frequency

Specs: Windows xp, ram
I have recently bought a new 512mb RAM with specifications DDR1 400MHz to add it to my old RAM. But it did not suite to my system. My old RAM shows figures of PC 3200 DDR400 RAM. I don't know what is the problem. Should I get my new RAM replaced or please suggest me the frequency of the RAM that I should take......

PC3200 aka DDR400 runs at 200MHz frequency, although the effective speed is 400MHz due to DDR technology.

We need to know the make/model of your motherboard.

so, does it mean that the effective speed of my new RAM i.e, ddr1 of 400mhz is going to be 800mhz due to ddr technology? Does it mean that I should get ddr1 RAM of 200mhz frequency. Is pc3200 ddr400 RAM a ddr1 ram or ddr2 ram? Please let me know sir. Awaiting reply. Thanks in advance.

Go to http://www.crucial.com

They have a "SCAN MY SYSTEM" button, this should inform you of the correct memory to purchase.

"does it mean that the effective speed of my new RAM i.e, ddr1 of 400mhz is going to be 800mhz due to ddr technology?"

NO! DDR400 runs at 200MHz frequency. But because of DDR technology, the speed is "effectively" doubled. If you want to call it 400MHz, that's fine, but you need to understand that the actual frequency is 200MHz.

In the following chart, frequency is called bus speed, hopefully it will help your understanding of the different types of DDR-SDRAM:

"Does it mean that I should get ddr1 RAM of 200mhz frequency"

You already have DDR1 RAM that runs at 200MHz frequency.

"Is pc3200 ddr400 RAM a ddr1 ram or ddr2 ram?"

The number 1 generally isn't used for the 1st generation of DDR-SDRAM, therefore DDR400 is DDR1. If it was DDR2, it would be called DDR2-400.

Going back to my 1st response: We need to know the make/model of your motherboard.
