How do I find out what kind of memory I need?

Like the title says, I want to upgrade my RAM but I'm not sure which variety I would need to buy to do so. I've checked the crucial website however, the make of my computer is not listed there. I'm kind of stuck so if anyone would be so kind as to instruct me how to find out I would be most greatful.

If you download this free programme click here. It will tell you what type of memory you have in your machine now. If you then click on the motherboard tab, it will tell you the make and model of the motherboard.

post the details here, so someone can advise you on what you can use.

Okay, thats the dealio for my whole computer. Right now I'm interested in the memory upgrade.
But, over the summer i'm looking to do some further upgrades. Bigger hard drive, etc. I was hoping someone might be able to tell me how strong a position I am in to do that with my current set up. Many thanks.

Can I ask why you want to upgrade your RAM.

I've been running a P4 2.4MHZ with 512MB RAM for around three years now. I don't play games or do video processing - and it does everything I ask of it.

Have you got a seperate graphics card, or an integrated graphics controller. If it's integrated, a better upgrade may be a graphics card - this will be faster, and free up some RAM from the integrated graphics back to the system.

has brought up some good points and worth thinking about.

back to the memory. Unortunatley cpu-z has not brought up what I had expected. It tells us that you have 512Mb of ddr ram, the speed of the ram should be under the spd tab on cpu-z.

it lists the motherboard as SIS 650, this is the graphics chipset. It says it is a NEC computer, but they are lots of models of these omputers and unless you know the make and model?

Try running the free version of SIW click here. This is a far more intensive programme and hopefully should tell us what you have. Thats if you still wish to check on the ram.

That program has done the trick pretty much I think.

So, is upgrading the RAM the best way to go,to keep myself ahead of the game anyway? As I don't really want this one dying on me and not really being much good to me in a couple of years. So, am I doing the right thing or is there something else I should be doing?


Again, thank you for all the help guys.

Currently you appear have two RAM slots, with a 256MB module in each - so to upgrade you will need to get, say two 512MB modules and sell of the 256MB ones.
