768GB DDR5 ECC RDIMM Kit for Supermicro H14DST-FL

This 12-module kit delivers 768GB of DDR5 4800 registered ECC memory built for the Supermicro H14DST-FL motherboard. Each 64GB DIMM runs at 1.1V with CL40 latency and a 2Rx4 organisation. It targets administrators who need maximum capacity across every slot without mixing ranks or speeds.

288-Pin Registered Form Factor and 1.1V Operation

The RDIMM register buffers address and command signals so the memory controller stays stable when all 12 slots are populated. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads. The 1.1V DDR5 voltage matches the board's native rail so no manual voltage tuning is required.

12 Pre-Matched 64GB Modules in a Single Kit

All 12 DIMMs ship together from the same production lot so rank, timing and voltage are identical across the kit. This eliminates the trial-and-error of mixing separate packs and lets the board train at full speed immediately. Buyers who need a different total capacity or a UDIMM form factor should look elsewhere.

Questions about this item

What DDR5 speed and CAS latency does this 768GB kit run at?

The kit operates at DDR5 4800 (PC5-38400) with CL40 latency and 1.10V voltage.

What form factor and pin count must the Supermicro H14DST-FL slots accept?

288-pin DDR5 RDIMM modules are required; the board uses registered ECC RDIMM slots, not UDIMM or SODIMM.

How do I install the 12 modules in the correct population order?

Follow the motherboard manual for the approved DIMM sequence; the kit is spec-matched to the board's population rules.
