how do I change RAM frequency?

Okay this might sound like a strange question but normally its a simple measure of putting in a new RAM chip when you want to add RAm to your desktop. strangely my new CPU ahs run into some preoblems with adding the RAM.

when I built my PC is january I wanted it to have 2 GB of DDR 2 RAM. however something is dodgy- when I put in two RAM chips into my motherboard it crashses every time without fail I ahve checked the slot configuration for the RAM and it's in the right position. however wen I put in one rAM chip it works fine.

A friend suggested I check my RAM frequency and how many channnels, but I have no idea how to change/chekc this. My motherboard manual is not helpful at all either. any ideas anyone?

by the way, the RAM chips are perfectly fine. I checked them out on someone elses CPU and they work alright. might be a problem with the motherboard, but I somehow doubt so.

for your info:
motherboard: MSI K9N NEO V3
ram: 2 kingston HYPERX DDR2 !gb

 

They may well be fine but sounds like either they are not really compatible with the motherboard or each other. Whether or no they work in another pc is meaningless. What matters is if they are listed at the mobo makers site or ram makers site as compatible specifically for your board.

 

the exact model? let me check.

is 'Kingston HyperX accelerate Gaming' the model you're looking for? on the packaging
it just says kingston DDR2-800 1.0GB HYPERX
on the plastic packaging it reads:

KHX6400D2LL/1G
1GB MEMORY MODULE 1GB PC2-6400 CL4 240in DIMM

and no, I do not have any other RAM chips in the CPU except the single stick of kingston atm.

by the way the compatibility report for the MSI motherboard cna be found here :
http://global.msi.com.tw/uploads/test_report/TR10_1244.pdf

the closest I cna find to mine is this one: KHX6400D2LLK2/2GN and this one KHX6400D2/1G which are found in the ddr2 800 and ddr2 667 sections respectively.

 

your ram is meant to run at a default of 2.0v, you can enter the bios by pressing the delete key on startup.

here's a link to your ram specs: http://www.directron.com/khx6400d2ll1g.html
motherboard manual which details the bios: http://global.msi.com.tw/index.php?func=downloadfile&dno=5570&type=manual

 

alright so I'm guessing its 'adjust memory speed' to 2.0v? what if thisn field is greyed out? its greyed out at 1.9v and I can't change it.
