ECC RAM not required?
And, based on the height of the CPU fans, I imagine it's not going to be a 1U rack .
The Supermicro H8QGI-F motherboard can use standard DDR3 memory and slower ECC memory. Limit with standard memory is 256GB, Registered ECC takes the system up to 1024GB. http://www.supermicr...6x0/H8QGi-F.cfm
Folding could work well with 4 1GB sticks per CPU. My 16 sticks of 2GB memory arrived today. I will also be using this computer for some other computational research, so I needed some more memory. Memory could easily be the most expensive part of high end systems.
And as the Cooler Master Hyper 212 EVO
is a big cooler. Definitely it will never fit into a 1U chassis. Even 5U would be tight. This will be a naked motherboard with all the hardware mounted on two stacked aspen wooden boards. Power supply, and SSD drive will be on the lower level along with the mass of cables. The motherboard will be mounted on the upper aspen board with cables between the two levels via routed cable slots. I will be finishing the boards and installing all the parts this weekend.
A keyboard and monitor will only be used during initial installation of Linux. After that, I will use secure shell connections to the system. As of today, I have 5 Operton 6176 processors, 16 sticks of 2GB memory, 850 watt power supply and the Kingston 120GB SSD. Only waiting on the CPU coolers for parts. Like I said, this will be a fun build.
I will also be installing a customized BIOS to enable overclocking this system. The limit is likely around 20% overclock from 2.3 GHz to around 2.76 GHz. No idea yet where the actual overclock will work out. My guess it will be near June 30 before this system starts processing work units. I will need to let the system stabilize and baseline itself before the overclocking starts.
