Re: Z420 RAM upgrade compatibility and performance concerns

AESystems, thanks for testing the 16GB RDIMM sticks in the Z420. Just to clarify, were you able to exceed the motherboards 64GB limitation too?

I'd like to pack my Z420 (running linux) with 125GB of RAM (and maybe an 8TB seagate Hard drive, which doesn't appear to be explicitly supported either). If you've had luck with 64+GB of RAM, I'll oder the parts to upgrade my system and report back.

Also, to head off the question "why do you need so much RAM?", I'll mention that I run high-reslution simulations of fluid flow, which utilize all the RAM I can pack into my computer. Being RAM-limited is no fun, either you have to work remotely on a supercomputer or process datasets in small chunks. I routinely have to restart my computer after I accidentally overload my RAM and my computer starts thrashing.
