•LRDIMM (Load Reduced DIMM, for X8DTU-6F+-LR and 8XDTU-6TF+-LR Only)

•LRDIMM DDR3 ECC 1066 MHz memory with support of up 288 GB in 18 slots

Warning: For your system memory to work properly, be sure to use the correct BIOS ROM for your system. For the X8DTU+-6F+, use the X8DTU+-6F+ BIOS. For the X8DTU+-6F+-LR, use the X8DTU+-6F+- LR BIOS. For the X8DTU+-6TF+, use the X8DTU+-6TF+ BIOS. For the X8DTU+-6TF+-LR, use the X8DTU+-6TF+-LR BIOS. To flash the BIOS, refer to http://www.supermicro.com/products/motherboard/QPI/5500/ X8DTN_.cfm?IPMI=Y.

•UDIMM

Unbuffered ECC/Non-ECC DDR3 1333/1066/800 MHz memory of up to 48 GB memory.
