512 GB DDR5 6400 kit of four 128 GB registered ECC RDIMMs at 1.1 V CL52 for Supermicro X14SRA-T
Size 512GB 4X128GB
This 512 GB kit contains four 128 GB DDR5 6400 RDIMMs built to the board's required 4Rx4 registered ECC specification at 1.1 V CL52. It targets administrators expanding memory capacity on a validated Supermicro X14SRA-T platform.
Swapping mixed-capacity or lower-speed modules for this matched quad-rank set lets every slot run at the rated 6400 MT/s without down-clocking. The jump is worth it when your workloads need the full 512 GB address space and registered ECC stability at the board's native data rate.
Consult the motherboard manual for approved slot order, maximum supported capacity per channel, and any BIOS revision required for 4Rx4 modules at this density. Confirm the chassis has 288-pin RDIMM slots and that the memory controller supports the 1.1 V operating voltage before ordering.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Yes, the 288-pin Registered DDR5 form factor matches the X14SRA-T DIMM slots exactly; the kit is spec-matched to the board's population rules.
Follow the motherboard manual's approved DIMM population order; the common mistake is filling slots sequentially instead of the prescribed channel sequence.
ECC corrects single-bit errors on the fly; persistent multi-bit errors or POST memory failures indicate a module that should be swapped under lifetime replacement.
