  • 64 GB kit delivers full capacity at rated speed because the 2Rx4 registered ECC modules match the memory controller exactly
  • DDR5 6400 CL52 at 1.1 V provides enterprise stability with on-the-fly error correction for uninterrupted operation
  • 288-pin RDIMM form factor fits the Supermicro X14SRG-TF motherboard precisely without UDIMM or SODIMM mismatch
  • Registered architecture offloads the controller so every slot runs fully populated at full capacity
  • Lifetime replacement warranty and US-based technical support back the upgrade for long-term reliability

Server-grade DDR5 ECC RDIMM kit

This 64GB kit delivers two 32GB registered DDR5 modules rated at 6400 MT/s with CL52 latency and 1.1V operation. The 2Rx4 organisation and ECC support match the Supermicro X14SRG-TF memory controller requirements for full-capacity recognition at rated speed.

Replaces slower or smaller DDR5 RDIMMs

Upgrading from lower-frequency DDR5 or smaller-capacity registered modules is worthwhile when workloads demand the full 64GB at 6400 MT/s with error correction. The exact rank, voltage and timing spec avoids down-clocking or population-rule conflicts on the target board.

Handles memory-intensive server workloads

The registered architecture offloads the controller so every slot runs fully populated at 6400 MT/s, while ECC corrects single-bit errors before they reach production. Capacity is fixed at 64GB; systems needing more memory must use a motherboard that supports larger DIMM counts or higher-density modules.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro X14SRG-TF motherboard slots?

Yes, the kit uses the 288-pin Registered DDR5 RDIMM form factor that the X14SRG-TF requires, not UDIMM or SODIMM.

What is the correct order to populate the two 32 GB sticks on this board?

Consult the motherboard manual for the approved DIMM population sequence; the kit must be installed in the slots specified for a 2Rx4 Registered ECC configuration.

Does the lack of a heat spreader affect long-term reliability under full load?

The modules are built with major OEM Samsung, Micron or Hynix chips rated for 1.10 V operation at DDR5-6400 CL52, and the Registered ECC design maintains stability without a spreader.
