Upgrading Ram A6040n

Microsoft Windows 8.1 (32-bit)

From help that I got in another thread on this site, I figured out that I can upgrade the processor in this computer to an Intel E6700.  But, I have now decided that I want to upgrade the RAM, too.  I'm not sure if I should now be putting a different kind of RAM in the computer (than what's in there already) because I will have a totally different processor.  


based on the label on the RAM in my computer, I have:

Hynix 1GB PC2-4200U-444-12


From reading the owner's manual of the motherboard, I notice that I should only install non-ECC RAM.  

But, the manual also says that the motherboard can support DDR2 667 MHz Ram.  But, I am not sure if that works with the better processor that I plan to install.  If I would like, can I stick with the current RAM type?  Can I/ do I have to switch to the better RAM?

The Intel 945 chipset your PC has, can can run the memory at 667 MHz, so you would definitely want to replace and upgrade the memory to PC2-5300 (667 Mhz) to have the memory run at the fastest possible speed it can.


The PC2-4200 memory slows the whole works down to 533 MHz, even with the Core 2 Duo E6320 processor you have in there now.
