64GB DDR3-1333 ECC registered kit

This 64GB kit contains four 16GB DDR3-1333 ECC registered DIMMs built for Supermicro H8DGU-LN4F+ H8QG6+-F H8QG6-F H8QG7+-LN4F servers. It runs at 1.5V with CL9 9-9-9 timing and uses 2Rx4 organisation on 240-pin modules.

What the kit changes

Adding four matched modules lets the supported Supermicro boards reach their registered ECC RDIMM ceiling of 1TB, far above the 128GB UDIMM limit. The registered buffer reduces electrical load on the memory controller so all sockets stay stable at 1333MHz.

Before ordering

Verify your motherboard is one of the four listed Supermicro models and that the CPU configuration populates the correct socket count. This kit will not fit boards that require unbuffered UDIMMs or a different DDR generation.

Questions about this item

Will the 240-pin DDR3-1333 registered DIMMs need replacement if the server motherboard is upgraded later?

These modules only fit 240-pin DDR3 slots, so a platform change to a different memory generation will require new memory.

What limit appears first when all 64 GB run continuously at 1333 MHz in the Supermicro H8DGU-LN4F+?

The kit provides 64 GB across four 16 GB ranks; the board’s registered DIMM ceiling is 1 TB, so capacity headroom remains very large.

How much heat and power do the 1.5 V CL9 sticks produce during all-day operation?

Each module runs at the standard 1.5 V DDR3 voltage with CL9 timing; registered buffering adds minimal overhead, so thermal output stays within normal DDR3 limits.
