  • 256GB total capacity from eight 32GB modules enables large-scale workloads
  • DDR5 5600 speed with CL46 latency delivers rated throughput for Supermicro H13SSW
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • 1V operation at 2Rx8 rank matches the motherboard's exact voltage and timing requirements
  • 288-pin RDIMM form factor ensures physical and electrical compatibility with the target server board

Exact-match upgrade for Supermicro H13SSW

This 256GB kit contains eight 32GB DDR5 5600MHz RDIMMs built to the board's required 2Rx8 registered ECC specification. Each module runs at 1.1V with CL46 timing so the memory controller recognises the full capacity at rated speed without manual tuning.

Sustained-load behaviour

Registered buffering reduces electrical load on the controller allowing all eight slots to stay populated at 5600MHz during continuous workloads. ECC corrects single-bit errors on the fly preventing silent data corruption that would otherwise force unplanned reboots in production environments.

DDR5 RDIMM practical limits

The 288-pin RDIMM form factor fits only motherboards wired for registered DDR5; it will not seat in UDIMM or SODIMM slots. Population order and maximum supported capacity are defined by the H13SSW manual so verify the approved configuration before installation.

Questions about this item

Does the 1.1V registered DDR5 kit generate noticeably more heat when all eight slots are populated continuously?

The modules run at the standard DDR5 voltage of 1.10V with a registered buffer that reduces electrical load on the memory controller, so thermal output stays within normal server DIMM limits even with the full 256GB kit installed.

What must the motherboard provide for this 288-pin RDIMM kit to function?

The board needs eight DDR5 RDIMM slots wired for registered ECC memory, a memory controller that accepts 2Rx8 organization at 5600MT/s, and a BIOS that supports the 1.1V operating voltage and CL46 timing.

Will the CL46 5600MHz registered ECC modules run correctly beside any older DDR5 DIMMs I keep in the same chassis?

Mixing DIMMs with different speeds, ranks, or timings forces the memory controller to downclock all modules to the lowest common settings, so the kit will only run at its rated 5600MHz CL46 when all eight slots use identical modules.
