  • 128 GB total capacity from four 32 GB modules enables dense server memory configurations
  • DDR5 6400 speed with CL52 latency delivers rated throughput for Supermicro X14SRG-TF
  • Registered ECC architecture with 2Rx4 organization maintains stability across all populated slots
  • 1 V operation matches the motherboard's voltage requirement for correct initialization
  • 288-pin RDIMM form factor fits the board's memory slots without adapter or modification

Exact-match upgrade

This 128 GB kit contains four 32 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. It is built for the Supermicro X14SRG-TF motherboard and delivers the precise rank, voltage and timing that board's memory controller expects.

Registered ECC architecture

Registered buffering offloads the memory controller so all slots can run fully populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. The 288-pin RDIMM form factor matches the board's required slot type; it will not fit UDIMM or SODIMM sockets.

128 GB total capacity

Four dual-rank 2Rx4 modules provide 128 GB of registered ECC memory for multi-socket server workloads. The kit runs at DDR5-6400 (PC5-51200) with CL52 timings at 1.1 V. Builds needing more memory than four slots provide or a different DIMM type cannot use this kit.

Questions about this item

What sustained-throughput limit appears first when all four 32 GB modules run at DDR5-6400 continuously?

The memory controller on the Supermicro X14SRG-TF sets the practical ceiling; the kit is rated for PC5-51200 bandwidth at CL52, so the controller’s maximum supported data rate becomes the limiting factor under sustained load.

How much heat and power does the 128 GB kit produce when the server runs 24/7 at 1.1 V?

Each RDIMM operates at 1.1 V without a heat spreader; registered buffering reduces electrical load on the controller, so total power draw and thermals stay within standard DDR5 RDIMM limits for a fully populated 288-pin configuration.

Which motherboard feature must already be present for this 2Rx4 ECC RDIMM kit to function?

The Supermicro X14SRG-TF must provide 288-pin DDR5 RDIMM slots that support registered ECC memory and the specific population rules for four 32 GB 2Rx4 modules at 6400 MT/s.
