I'm not good with computer hardware so need to seek help here with regards to which type of RAM to ask for if I want to buy one
The details from CPUZ are as below
DDR2 RAM. Your motherboard support dual channel RAM, so if you game or do anything intensive, you can make good use of it.

By the way, if you are using a 32-bit operating system, there's no point installing more than 4GB of RAM since you won't be able to utilize the extra amount of RAM installed.
To check...
Right click on Computer (in Start menu) and select Properties. Or go to Start > Control Panel and double click on System.
okay thanks for the useful website!
