I had strange problems with some memory chips that only Newer's Guage Pro Memory test would find. Newer's test writes a pattern out to all free memory, then reads it back in. It stress' the system memory throughput overall as opposed to most memory tests which are designed to test chips. -- -- Mr. PopMan - [EMAIL PROTECTED] - "Does anybody want to play a game of pinball?"
