24GB ToTal Memory 3 pieces of 8gb DDR3 ECC REGISTER PC10600 240 PIN DIMM Lifetime exchange or repair warranty against manufacturing defects. Manufactured by Computer Memory Solutions Compatible with: Dell PowerEdge T710 Max Memory 48GB ECC UDIMM 192GB Reg ECC RDIMM Sockets12 OR 18 NOTE We offers "K3" kit part numbers for Triple Channel mode. OUR DDR3-1333 modules automatically clock down to 1066MHz and 800MHz depending on which Intel Xeon model and the number of modules installed. Due to chipset limitations, OUR DDR3 Quad Rank memory will operate at 1066MHz in the first Triple Channel bank. Adding Quad Rank modules in the second Triple Channel bank will operate at 800MHz. This system supports either Registered ECC or Unbuffered ECC memory. Mixing Registered ECC and Unbuffered ECC modules is not supported within this system. 4GB DDR3-1333 Reg ECC modules come in two versions: 313/4G using x4 and 3138/4G using x8 DRAM. The two parts may be installed in the same system but not within the same memory bank. Use like modules for dual and triple channel operation.
