Why You Need a Memory Tester

If you are using a motherboard to test memory you know that it can take hours or even days. Conflicts between the memory and the motherboard can make it appear that the memory is faulty, yet the memory may work just fine in another computer. Worse, the memory sockets on PC motherboards are not meant for repeated insertion/removal of modules and will quickly break! The RAMCHECK LX memory tester will test and identify your memory module in just seconds. It uses rugged sockets made specifically for high-volume memory testing that will last for thousands of cycles. You won't have to wade through a lengthy set-up process.
