Installing more RAM on my PC

As I am increasingly getting Windows “low virtual memory” warnings, I have been advised to install more memory on my PC – a Dell Dimension C521.

A system scan by Crucial.com reveals that I have 1GB of RAM installed and three empty slots. They recommend installing up to three extra 1GB in matched pairs and offer to sell me “guaranteed compatible” RAM for £14.39 per GB.

Presumably adding 3GB will be beneficial? However, Crucial’s advice includes two things I don’t understand.

1. It says “Your PC can handle 4096 MB”. I get confused over MB and GB. Can I have a total of 4GB RAM on my PC?

2. In saying each memory slot can take 1GB, it says “Not to exceed manufacturer supported memory”. I don’t understand that.

Also, you will probably have realised that my knowledge is limited, albeit I am fairly intelligent (!). Is it easy for someone inexperienced to install extra RAM?

Any advice will be greatly appreciated.

Q2. Can the speeds in a matched pair be mixed? In other words, if the existing stick is 5300, is it OK to install a 6400 alongside it.

A. NO, they will be two odd ones. A matched pair means just that - matched, the same, not different.


Q3. If the existing stick is 5300 and I install another 5300 as its pair, must the second pair also be 5300 - or can it be 6400? Would I get better speeds if I made the second pair 6400?

A. You can have two 5300 sticks and two 6400 sticks. The 6400 sticks will run at the speed of the slower 5300 sticks. Just make sure you put them in the correct slots to make pairs (slots are colour coded so you don't get mixed up)

You could install the 2nd pair as 6400 but no point as the comp will run at the lower speed of 5300. So might as well put in 5300. Alternatively buy 4x1g 6400.

"I was hoping to find a way to ascertain the speed of the existing RAM without having to open the case. Because of my setup, it is awkward to access it."..

You are going have to open it up to put Ram in !
