Take note that when shopping for RAM, the types of specs listed above will most likely be listed with the product. But when looking for information on what type of memory is compatible with your computer, it may only list the Pins, Frequency, or the PCXXXX number. If that’s the case, use what they list as your primary focus when choosing new memory. If there’s another specification that your manufacturer lists that has not shown up in this guide, use that as well. Choosing the right memory for your computer is a bit of a heavy task. It’s important to conduct some research as well as it is to ask questions. Ultimately, just make sure you search for memory that will work within your computer’s limits and your quest will become much easier.
When buying a new computer, it is always an investment. As such, replacing RAM should be approached in the same manner. If you go with a cheap, unknown brand to replace your memory, it may be a costly mistake. RAM is a key component of your computer's hardware. If it fails, so will your machine. In turn, I suggest brands like OCZ, Kingston and Corsair. Don’t penny pinch!
