Nehalem EP Workstation Review (Not a Mac) but Non-ECC memory worked fine...

Interesting notes on RAM...

With Samsung's recently announced 16 GB DDR3 R-DIMMs, you can pack a humongous 192 GB RAM in this box. Given the pricing of the parts, this could mean that you can start thinking about having a super computer on your desktop, instead of usual off-loading demanding tasks - large servers or supercomputers. The test configuration was equipped with twelve 4 GB ECC R-DIMMs, also from Samsung, for a total of "only" 48 GB memory - still the largest memory PC to ever enter my lab.

Now, I was curious whether Super Micro will block me from running the standard Core i7 DDR3 DIMMs, like the fast DDR3-2000 3-channel kit from Kingston. After all, these are very fast modules - CL8 at DDR3-2000 being achievable on ASUS Rampage Extreme with the newest BIOS - but they are the unbuffered, non-ECC desktop kind. So, I replaced the entire DRAM with six HyperX modules, one per each CPU's memory channel. Guess what, they worked! At only DDR3-1333 speed though, as the BIOS option for "Forced DDR3-1600" didn't seem to take effect.

We already know non-ecc memory works in the Mac Pros. You even posted in the thread where WonderSausage posted his finding
