As map9966 says check the link, allthough it's not working for me now i would guess your problem is that you are currently running on PC2100 RAM sticks which has a default bus speed of 133MHz and may not perform well in dual channel. it could also be that you are running a processor (CPU) with a lower bus frequency. example: Intel Celeron 2,6GHz with 400MHz Bus frequency wouldn't run at top speed because of the difference in the FSB and memory bandwidth.
Note: DDR in dual channel is not indicated as 800MHz anywhere; however in dual channel (with PC3200) both memory modules run at 200MHz each which results in a "dual channel" = 400MHz.
I think you might be mixing up the FSB on the processor with the RAM frequency:
CPU - FSB on this board is 800MHz (P4 exists in 400, 533 and 800MHz)
Memory on this board is 200MHz per channel (400MHz in dual) (PC3200)

Check your manual and find the QVL list. Memory tested to work in your board is listed there. I found a link that shows your board. Click the Download on the left & check your manual.
You Max speed is 400Mhz memory as you will see at the link.

Please vote...

How to add memory? what is the proper memory?

Here is the stats on your bored

Memory Memory Type dtrquestion.gif SDRAM Max Supported RAM dtrquestion.gif 1.5 GB

your bored takes sdram and is only upgradable to 1.5gigs total

To upgrade your bored. you will see on you bord some long slender black sockets. that should already have a stick of ram in it. You will see on the end of each one like a pin that holds it in place. Just push them down, and it should open them up. You can pull the old one out and put a new one in. Or just simply push a new stick down into it, tell those little pins snap back into place holding the stick of ram. They will only go in one way so don't force them.

if this was helpful and answered your question please mark it fixya and rate me as well as recommend me.

It means the most your motherboard will support per slot is a 256 RAM. Also, on older systems, some RAMs are not compatible with others.
