RAM

Similar to the CPU and motherboard, when purchasing memory modules for a server it is smart to buy server grade products, which offer enhanced scalability, stability, and error checking. For this reason we decided to use ECC registered memory. Error-correcting code memory (ECC) utilizes parity checking to check for and correct data errors. Registered memory allows the system to place less load on the memory controller and enables the system to handle greater amounts of RAM. Since the servers we are building will be responsible for serving multiple virtual computers we need as much RAM as possible in order to run as many virtual machines as possible. The larger computer server will support 12 x 4 gigabyte ECC registered DDR3 DIMMs for a total of 48 gigabytes of memory. The smaller server also has parity checking memory and will use 6 x 4 gigabyte ECC DDR3 DIMMs.

Video Demonstration

In this video we demonstrate how to properly seat memory sticks on the motherboard. You must orient the notch on the memory stick and apply firm pressure on either end of the stick until the memory latches in place. For this server, we installed a total of forty eight gigabytes of ECC registered DDR3 memory.

In this video, we connect all of the cabling. Power cables are connected to the motherboard and power and data cables are connected to the SATA hard drives and the CD/DVD drive. A power cable is connected and then daisy chained to all of the server case fans, and the power and reset switches and led light cables are properly connected to the correct motherboard pins.
