Without a doubt, compatibility is the most important factor in buying a memory upgrade for your laptop or computer. Your RAM must be compatible with your system — or your system just won't work. With so many variations in memory, it's important to understand just exactly what will work — and what won't — in your system. Using the Memory Advisor or Scanner on Crucial.com is the best way to ensure compatibility. 100% guaranteed. Or your money back.
