ram speed

[gecko]

i picked up some kingston ram the other day from the local computer store, and the guy told me it was 400MHz but when i open up CPU-Z and click on the 'memory' tab it says under 'timings':
frequency 199.9 MHz
FSB: DRAM 1:1
CAS# Latency 2.0 clocks
RAS# to CAS# Delay 4 clocks
RAS# Precharge 4 clocks

the ram is 512MBytes and i have two of them running in dual channel mode.
if it makes any differance im using an ASUS p4p800se mobo and a P4 3.4Ghz northwood.

frequency would be the only thing im worried about, the other stuff is good but i dont get why its 199.9mhz

Nothing ever runs exactly on the speed its labelled as, mines running 200.7 right now.

so is the guy who sold it to me wrong: its not 400MHz but actually 200MHz?

 

[Cromewell]

Its DDR so it effectivly runs at 400MHz. It's like your CPU, it's FSB is 200MHz Quad Pumped to 800MHz.
