Exact-fit server upgrade

This 1TB kit contains eight 128GB DDR5 registered ECC RDIMMs built for the Supermicro H14SST-GE motherboard. Each module runs at 6400 MT/s with CL52 latency at 1.1V in a 2Rx4 configuration. The registered design lets the board run every slot fully populated at rated capacity.

DDR5 registered DIMM limits

Registered DDR5 RDIMMs buffer address and command signals so the memory controller can drive a full complement of modules without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption. The 288-pin form factor fits only DDR5 RDIMM slots, not UDIMM or SODIMM sockets.

2Rx4 rank architecture

The dual-rank by four organisation determines how the memory controller interleaves accesses across all eight modules. Population rules in the board manual dictate which slots must be filled first to enable full 1TB operation at 6400 MT/s.

Questions about this item

Should I choose the 8 x 128 GB kit or a different capacity for my Supermicro H14SST-GE?

This kit provides exactly 1 TB in eight 128 GB modules, matching the board's 288-pin RDIMM slots and 2Rx4 rank layout so the memory controller recognises full capacity at rated speed.

What does the 6400 MHz rating mean once the modules are installed in the server?

The DDR5 6400 (PC5-51200) modules run at 6400 MT/s with CL52 latency at 1.1 V, delivering the bandwidth and timing the motherboard's memory controller expects when fully populated.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered (buffered) 288-pin RDIMM interface offloads the memory controller, allowing all eight slots to run fully populated at 6400 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
