What is a Memory Module Tester ?Memory module testers are very specialized test equipment used to test and verify memory modules typically in SIMM or DIMM configuration. It detects functional failure on memory modules before they are installed into the computer system.
Memory module testers can be broadly categorized into two types :
Memory testers are classified into several categories
Mid-range memory testers typically priced under $100,000, are commonly found in the SIMM module manufacturing assembly houses. These testers are built to support mass volume memory module testing. They are also used for detecting assembly faults caused by mis-soldering and cross-cell contamination after chips are assembled onto PCB or SIMM cards. These memory testers are usually docked onto an automatic handling system for high volume production testing, thus eliminating manual intervention by an operator.
Low-end memory testers are usually relatively low cost ranging from $1000 - $3000. Their main features are portability, ease of use and relatively small size. They are typically used by the service industry especially by computer service technicians, RMA departments, memory reseller/brokers/ and wholesalers for verifying and testing memory modules that fails in PC system or before going into PC. Quality and features of this range of memory testers varies greatly depending on the manufacturer. A good memory tester is built with features comparable with high-end ATE and medium range memory tester. The key is to provide a simple to use tester at an affordable price that is still effective in capturing most memory faults and failures.
Memory diagnostic software are very low cost tools used to check for memory failures on a PC typically priced from $ 9.95 to $200. It is usually in the form of a self-bootable software program on a floppy disk. The diagnostic tools provide memory test patterns which are able to test memory starting from the base memory to extended memory. The main disadvantage of software diagnostic program is when your PC refuses to boot-up due to memory failure or a faulty motherboard, then the software diagnostic is rendered useless.
