1TB DDR5-4800 ECC RDIMM kit for Supermicro servers
This registered DDR5 memory kit delivers 1TB total capacity across eight 128GB modules. It is built for Supermicro SuperWorkstation SYS-751A-I and X13DAI-T platforms that require ECC RDIMM memory. The modules operate at 4800 MT/s with CL40 latency at 1.1V.
Eight-module kit simplifies full population
The package provides eight matched 128GB RDIMMs in a single kit, removing the need to source individual sticks and reducing the risk of mixing revisions. Each module uses a 4Rx4 organisation with Samsung, Micron or Hynix die and no heat spreader, matching the density and electrical profile the validated platforms expect.
4Rx4 rank layout dictates slot population rules
The 4Rx4 configuration means each DIMM presents four ranks to the memory controller, so the maximum supported rank count per channel determines how many slots can be filled. Builders must verify the platform’s rank-per-channel limit before installing all eight modules.

Questions sur cet article
Will the 128 GB DDR5 RDIMM modules need periodic replacement or maintenance after installation?
No scheduled maintenance is required; the registered ECC DDR5 modules run at 1.10 V and are built for continuous server operation.
What is the first limit reached when the 8-module kit runs at DDR5 4800 CL40 under sustained load?
The CAS latency of CL40 at 4800 MT/s sets the timing boundary before bandwidth or thermal limits appear.
How much noise or extra heat do the 288-pin registered DIMMs add when the workstation runs all day?
The modules have no heat spreader and operate at the standard 1.10 V, so they add negligible heat and no audible noise beyond normal chassis airflow.
