Actually, the high speed digital testers employed by the memory manufacturers FULLY test memory modules over their rated speed and voltage ranges. Usually any problems that occur after the module leaves the factory are due to handling, installation or motherboard related issues (timing, voltage, noise, etc.) Memory chips themselves are 100% parametrically tested after they are packaged since the manufacturer is in the business of selling specified, functional chips. At any rate... if anyone is interested in FULLY testing your system memory, you can get a great FREE memory test program at: http://www.teresaudio.com/memtest86/ It will exercise all your memory, CPU cache memory, etc. If there's a memory bug, it will almost certainly find it. An invaluable tool for evaluating your hardware setup.
