  • 288-pin RDIMM form factor ensures correct physical and electrical fit in every supported slot

512GB DDR5 RDIMM kit for Supermicro X14SRG-TF

This 512GB kit contains four 128GB DDR5 6400 Registered ECC RDIMMs built for the Supermicro X14SRG-TF motherboard. Each module runs at 1.1V with CL52 latency and a 4Rx4 organisation. The registered design lets every slot stay populated at full speed.

Suited for servers needing maximum registered ECC

Administrators expanding a Supermicro X14SRG-TF to its full 512GB limit will match the board's exact voltage, rank and timing requirements. Builders using consumer boards, laptops or workstations that accept only unbuffered UDIMMs or SODIMMs cannot use these registered modules.

Handles full 512GB population at DDR5 6400

Four 4Rx4 RDIMMs fill every slot while the registered buffer offloads the memory controller and ECC corrects single-bit errors in flight. Systems that require lower-voltage 1.1V operation stay within spec. Boards limited to fewer slots or lower maximum capacity will not accommodate the full kit.

Questions about this item

Do I need a Supermicro X14SRG-TF motherboard with DDR5 288-pin RDIMM slots to install this 512GB kit?

Yes, the kit is built for the Supermicro X14SRG-TF motherboard and requires its 288-pin DDR5 RDIMM slots; it will not fit UDIMM or SODIMM sockets.

If I keep some older DDR5 RDIMMs in the same server, will this 4Rx4 CL52 1.1V kit run alongside them?

Mixing ranks, latencies or voltages can force the memory controller to down-clock all modules; the board manual should be checked for approved population rules before combining kits.

How can I confirm the system sees all 512GB at DDR5 6400 CL52 after installation?

Enter the BIOS or run a hardware inventory tool such as dmidecode; it should report four 128GB RDIMMs at 6400 MT/s, CL52, 1.1V with ECC registered active.
