Hi John, I have a working hypothesis for you: if the memory isn't from the same manufacturer/batch, and you're having problems with it, you should send it back and get memory that is. Here's why... Last year I bought a DELL 530 Precision Workstation (I know, I know... but it's a Brute of a machine to do my 3D work on... and Max doesn't run on a Mac) and bought the memory from an East-Coast place. I specifically asked for all the memory (2Gigs of RAMBUS) from the same manufacturer, from the same batch. They moaned about the impossibility of this from a fulfillment/distribution stand point, blah blah blah, and sent me two sticks from from the same batch, and two miss-matched sticks. When I called, they said give it a try-if it didn't work, they'd make good on it. For the next two weeks I routinely tortured all the RAM-I was working on a rather large architectural project and watched Max fill, unload, fill, unload-rinse and repeat ad nauseum, during a very intense period of rendering. When the memory filled up, oft-times it crashed. Hard, nasty crashes that brought the whole house down, corrupted files, the whole ball of wax. I finally gave up, called the east coast place, sent it back. They sent me 4 new sticks-what I'd originally asked for - and I haven't had the problem since. It has been nearly a year now. Send it back and ask for the same RAM from the same manufacturer (at least) and preferably the same batch. I'm telling ya... Good luck, John B.
