  • 512 GB kit delivers maximum capacity for Supermicro H14SST-G
  • Registered ECC architecture prevents data corruption under full load
  • DDR5 4800 speed matches the motherboard's rated specification
  • 1 V operation reduces power draw per module
  • 8 × 64 GB layout populates every slot at full density

Exact-match 512 GB server kit

This 512 GB kit contains eight 64 GB DDR5 ECC registered DIMMs built for the Supermicro H14SST-G motherboard. The modules run at 4800 MHz with CL40 latency at 1.1 V and present a 2Rx4 rank layout that the board's memory controller expects.

Sustained-load behaviour

Registered buffering offloads the memory controller so all slots stay stable when fully populated at rated speed. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous production workloads.

Upgrade scope and limits

The kit replaces any smaller-capacity or slower DDR5 RDIMM set that fits the same 288-pin registered slots. It is not for systems that require unbuffered UDIMMs, SODIMM form factors, or a different DDR generation.

Questions about this item

How much power does the 1.1V DDR5 kit draw when the server runs continuously?

The modules operate at 1.1V and use DDR5's on-die power management to reduce idle draw, so sustained load stays within the board's standard DIMM power budget.

What must the Supermicro H14SST-G motherboard already support for this 512GB kit to function?

The board needs eight 288-pin DDR5 RDIMM slots, a memory controller that accepts 2Rx4 registered ECC at 4800 MT/s, and BIOS support for 64 GB per DIMM.

Will the CL40 4800 MT/s modules run reliably alongside slower DDR5 DIMMs I keep in other slots?

All populated slots run at the lowest common speed and latency; mixing slower DDR5 forces the kit down to that slower rate and may violate the board's population rules.
