the simplest thing to do is look in your motherboard manual if you have it to find the memory that your system uses. Then enter the details in froogle etc to see who is doing it the cheapest. Crucial normally give the right info but are one of the dearest. You can get a 5% discount from them by entering using click here and using the code shown when you buy.
Thats why it was nearly 3 times more expensive to buy mine on crucials site. Thus I went to click here and got the exact same ram from the same people at nearly 1/3 the price. £10 more for guaranteed compatibility. 2/3 more no thanks. Will take my chances and likely still come out saving.
