Interesting... I'm in the process of ordering a pair of R905's to run Eucalyptus for a cloud-computing lab for the CC Department here at Rutgers. I'm ordering them with Four Quad Core Opteron 2.2GHz (total of 16 cores) but "only"[*] 16 GB of RAM (8 x 2GB sticks) with the intention of adding Crucial (or other reputable 3rd-party) RAM after the project gets started and we can gauge how much RAM we "really" want to put on it. The theory is that adding processor chips is tricky but adding RAM DIMMs is easy.
That's the theory, anyway. Ski's experience gives me reason to question that theory. Anybody got a better theory, before we go and spend the money? BTW: On the "customization" page for the R905, Dell has the warning "Memory configurations with greater than 4 DIMMs per processor cause memory to clock down to 533 MHz" (It's normally rated at 667 MHz). I don't know if this relates to Ski's problem, but it caught my eye anyway... Enjoy! Rick [*] How many people remember when 16 KB of RAM was a lot?!
