ok i have an MSI pm8m2-v mobo and i have 2 gb of ram on it only it doesnt run at the speed it supposed to....when i run cpu z it says my computer is running it at 200 mhz instead of 400 mhz....my memory is capable of 400 mhz so why isnt it running at that speed... and when i go into the bios i dont see anything about settig the memory frequency....does this mean i have to overclock my memory timings to get the correct speed?

MOBO Specs:

? Intel? P4/Prescott(LGA775) 800/533 FSB CPU Support
? VIA P4M800/VT8237 Chipset
? 2x 266/333/400 MHz DDR up to 2GB
? 1x AGP 4/8X AGP Slot
? 2x PCI Slot
? 2x ATA 66/100/133 IDE Controller
? Realtek ALC655 6 Channel Audio
? S3 Unichrome Pro Graphic Controller Share up to 64MB
? VIA VT6103 10/100 Ethernet Controller
? 1x Floppy Port / 1x Serial Port / 8x USB 2.0 Ports

If not then do this, then your speeds will increase a little and the specs that you will be looking for will either be near or spot on to what you are looking for.
Go here for the MSI web site:

Please post back if you have any more problems or questions.

You have Dual Chanel RAM on a Dual Chanel M'Board. If the RAM is fitted to the correct Sockets each stick will run at 200 MHZ so when you add 1 Stick @ 200 and the second Stick @ 200 MHZ this gives you a 400 MHZ RAM Speed addressing the CPU. It is the Speed of the CPU not the actual RAM here that is what you are looking at.

It is the CPU which uses the 400 MHZ not the actual RAM.

But if you have the RAM incorrectly fitted you will be running in Single Chanel Mode at 200 MHZ. Generally there are different color RAM Sockets and you need to fit the RAM to sockets 1 & 3 not 1 & 2 or 1 & 4. If you have 1 lot of 2 Sticks of the same type and size in the second RAM Bank these will also allow the M'Board to run in Dual Chanel Mode but if you add only 1 Stick or different size sticks in the other RAM Sockets the M'Board will only run in Single Chanel mode reducing the maximum performance of the system.

hmmm ok well i know my ram is fitted correctly because both of my sticks show up in the bios....ok now for the next question....why is my FSB set to only 200 mhz in the bios when my mobo supports 800 mhz as well as the processor i am using which is a P4 3.0 prescott....and i cant change my fsb settings in my bios so what can i do to change this....btw thanks for the last answer....helped a bunch

You can have 2 sticks of RAM but not in the correct sockets so it runs as Single Chanel not Dual Chanel.

As for the M'Board supporting 800 MHZ this is because it supports different CPU's with different FSB's.

The Speed of the CPU or the FSB of the CPU is listed on the Intel CPU Technical Specification Sheet here
