Question on pc3200 speeds

[Hiero]

Hey guys,

I was just woundering why when i have a look at what my 512mb of ram it says under SPD in CPU-Z the "Max Bandwidth is PC3200 (200mhz)" when PC3200 ram is ment to be 400mhz ? why is this and is that what it should be?

PC Specs:

AMD 3500+
Asus A8V Deluxe
512mb Ram 400mhz
Radeon 9550 256mb

Im not sure if this is where im ment to post so sorry if it isnt.

Thanks guys Hiero.

Hello and welcome to Techspot.

Nothing to worry about.

An fsb of 200mhz is 400mhz effective.

So, your ram is running at the correct speed.

pc3200=DDR 400mhz=fsb of 200mhz=400mhz effective.

pc2700=DDR 333mhz=fsb 0f 166mhz=333mhz effective.

pc2100=DDR 266mhz=fsb of 133mhz=266mhz effective.

Regards Howard :wave: :wave:

that's because dual-cycle ram runs twice per cycle. 200mhz ram x 2 = 400mhz
