PC Peripherals Hynix Ram Speed confusion

[Dare Devil]

I have a PC with the following config.

Intel P4 3.0 Ghz HT
Intel 915 GAV MOBO
512 MB DDR (400MHz)
80GB HDD
CD Writter
DVD Drive
TV Tuner Card
Internal Modem
Web Cam
800 watts Speakers
15" CRT Monitor
422 watts zebronics SMPS
500 VA UPS.

I have Hynix 512MB DDR(400Mhz).But Everest Home Edition shows like the following
Module size: 512MB
Memory Type: DDRSDRAM
Memory Speed: PC3200(200).
It shows me the memory speed is 200Mhz.But in BIOS setup the system Memory speed is 400Mhz.Please explain the confusion about my RAM speed.

Thats correct.
DDR400 is also called PC3200.
Also it detects as 200 MHz as 200x2 = 400,sint it ?
even if you check in CPU-z,speed is shows like that only.
As the RAM you are using is DDR ,Double Data Rate.
