i recently bought 512mb pc3200ddrram 400mhz(geil)which is in ok and works but when i checked it out in aida32 it says the ram speed is only 200mhz :?: my board ga-7vt600 1394 supports 400 mhz :?: am i just thick or is this incorrect thanks in advance for any feedback :P

This is probably correct - DDR = double data rate. I.e. it actually runs at 200MHz, but because it transfers data at double the rate of single data rate (SDR) RAM it runs at the speed equivalent to 400MHz SDR - hence it is marketed as 400MHz. The same is true of other DDR memories - 333MHz DDR actually runs at 166MHz and 266MHz DDR at 133MHz.

i.e. nothing is wrong :) Somewhere in aida it should tell you the EFFECTIVE data rate, which is 400MHz.
