Exact-fit server upgrade

This 128GB kit delivers two 64GB DDR5 6400 registered ECC RDIMMs built to the Supermicro X14SRG-TF motherboard's exact specifications. The modules run at CL52 with a 1.10V operating voltage and a 4Rx4 rank structure so the memory controller recognises the full capacity at rated speed.

DDR5-6400 registered limits

Registered buffering lets every slot run fully populated without overloading the controller, while on-die ECC corrects single-bit errors before they reach production workloads. The 288-pin DDR5 interface tops out at 6400 MT/s (PC5-51200), so throughput is capped by the platform's maximum supported data rate.

No spreader, standard mounting

Bare modules without heat spreaders fit tight DIMM spacing on dense server boards and rely on chassis airflow for cooling. The 288-pin RDIMM keying prevents accidental insertion of UDIMM or SODIMM parts, and the two-module kit matches the board's dual-channel population rules for immediate recognition.

Questions about this item

Should I choose this 128GB 2x64GB kit or a different capacity for my Supermicro X14SRG-TF?

This kit provides 128GB total across two 64GB RDIMMs, matching the exact rank, voltage, and timing the board's memory controller expects for full-capacity recognition at rated speed.

What does the 6400MHz speed mean once installed in the server?

The modules run at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, delivering the rated data rate the motherboard supports when populated per its memory-population rules.

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

The 288-pin Registered DIMM form factor is required by the X14SRG-TF; registered architecture offloads the memory controller for full-slot operation, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
