ECC not supported
The installed DDR3 DIMM should support the Serial Presence Detect (SPD) data structure. This
allows the BIOS to read and configure the memory controller for optimal performance. If non-
SPD memory is used, the BIOS will attempt to configure the memory settings, but
performance and reliability may be impacted.

Unscrew memory protection bracket from the chassis side wall by unscrewing the two
screws on the memory hold down bracket (see figure 25)
2.
