RAM MHz decision

[nw-woman]

My Pavilion p6213w x64 has 6.00 GB physical memory (RAM) and I want to add 2GB, which it does support.

It's supports 8GB on 64-bit 240 pin... so I want 2 GB DDR2 Dimms, non-eec mem unbuffered.  

However, it also suppoprts PC2-5300 (667 MHZ) or PC2-6400  (800Mhz) .

I do not know how to make a decision as to which MHz to buy.

Can someone tell me?  I called a support shop.  They would not say.  Told me I had to book a repair time to bring it in.  I want to pop it in myself.

OK.. I found an executable that I ran on my desktop which told me my memory configuration without need to open it up.  Should anyone else be reading this... I have 4 slots all of which are filled .. 2048 and 1024 MB in slot 1, 2 and repeated in 3, 4. And they are 800 MHz...

The following link shows specs of your computer

It clearly says currently it has total 6GB 800MHz and you can see from a program which shows configutaion is for your machine  2 + 2 + 1 + 1.

It supports 8GB max (each slot supports only 2GB) therefore you can buy 2 x 2GB DDR2 800MHz RAM and replace them on slots 3 and 4.
