Hi, I bought 512MB DDR400 PC3200 Ram, I have been told to run it 400 does anyone know how I do this?

Thanks

Hey. The motherboard should detect it automatically at that speed, if the processor your using is meant to be run at a core FSB (front side bus) of 200.

If not, (this is overclocking), go into your BIOS (press delete during the disk detection at startup), go into the section for FSB ratio (or something similar) and check to see what it`s set to.

Need more help, let us know!

The FSB (front side bus) of your processor has to be 400Mhz (200Mhz double pumped if AMD Barton core) or more for PC3200 memory to run at 400Mhz.

To check this, download a program called CPU-Z which can be found here , and run it. It will tell you all about your memory, motherboard and processor.

Heres a screenie of what you should be looking for, my memory is PC2700 (333mhz) thats why it says 166Mhz because you have to times it by 2 (hence DDR- Double Date Rate). So if your memorys running at 400mhz it will read at 200 on the CPU-Z memory screen.

Hi, Thanks for your help.

I downloaded the prog and it says Bus Speed 332.7 MHz.
On the Memory page it says Frequency 199.6 MHz

I've never done this before but I can't see 400 MHz anywhere, what do U need to change.

Cheers

Well im afraid the highest your memory will run at is 333Mhz, unless you get into overclocking :(.
 
Hi,

Ok thanks, Just that's what Micro Direct told me to run it as, as they sell it as DDR400, would it make much difference to the performance anyway?

You wont really notice the difference between a computer running at 400Mhz FSB and 333Mhz. Certainly its there, but nothing to write home about ;).
 
Could have sworn that both the 3000+ and the 3200+ were 400MHz.

There are a few versions of each chip so i guess thats one of the more uncommone ones...
 
I thought the 3200+ was the only XP to have a FSB of 200MHz default. Ah well....
