Awesome, great information! I'll consider this as well as I keep looking. Thanks!

jonathanm and snuffy1pro: Thank you both!!

This question is about ram compatibility. This is my first build (ever) and I am trying to follow the techspot article closely with the exception of RAM due to its price (components listed at the end) and because it seems that ECC ram is better for scientific computing. The computer will primarily be used for machine learning for academic research, some deep learning, and various other tasks (browsing, writing, etc.). As a newbie, I'm finding RAM compatibility to be incredibly confusing. The Xeon spec list says that the total possible is 384 gb, accepting types ddr3 800/1066/1333/1600. The motherboard spec list says there are 8x240 pin DDR3 DIMM slots accepting up to 256GB DDR3 R/LR DIMM or 64 GB unbuffered UDIMM. There is a memory QVL which gives a small list of "approved" types of DDR3 (mostly Kingston brand). My question is: Will any ECC registered 240 pin DDR3 work in this set up? I see lots of good deals on ebay, but I hesitate pulling the trigger because I am unsure about compatibility. I am looking for 64 gb or 128 gb kits. Thank you!
