When starting up my new PC the POST screen shows my memory running at 200 MHZ,the processor is a XP 2500 Athlon which is shown correctly,the FSB should be 333 MHZ,the RAM is DDR 400 PC3200,there are no jumper settings on the motherboard for speeds,do I need to do a manual setting in the BIOS to reflect these components,the install book say leave default ( motherboard ECS N2U400-A )
any help,

with most boards theres normally a jumper to select fsb speeds tho it could be a bios setting (i'm not sure with that board). 200mhz is usually default. consult the manaul. yu will need to set it to suit the cpu.

Thanks Tweak'e,
There is a setting in the BIOS ( advanced chipset features) which has the FSB as a number ( not default or optimal ) I can try and adjust it to 333 MHZ.it looks like you can set FSB speed and RAM speed and the it works out and gives a " resulting frequency " further down the same page.

Go into your BIOS, Click on "advanced cipset features" and there is a listing for "FSB Frequency" which you can change to 166.

whats your problem?

are you wanting to slow the ram down to match your fsb,or are you thinking at 200mhz its displayed incorrectly?

Your clock speed for the AMD 2500 should be set to 166Mhz Not 200Mhz as this creats a FSB or 400Mhz and the 2500 is only a 333Mhz FSB CPU. Having the setting at 300 is overclocking the cpu and may result in damaging it if you don't have adequit cooling inplace.

Bah screwed up :D the 300 should say 200 Do'h

The cpu speed is reported correcty thus it isnt overclocked,the 200mhz just means his ram is running at 2x200mhz,hence ddr400.

I cant see what teh problem is.

thank you all for your input I have set FSB to 166 from 100,the result is still 200 MHZ on the startup POST but from your input I am happy to leave it as is.
