  • 192 GB total capacity from two 96 GB modules for maximum memory density
  • DDR5 4800 speed with CL40 latency matches the server's rated timing
  • 1 V registered ECC RDIMM design offloads the memory controller and corrects single-bit errors
  • 2Rx4 dual-rank organisation enables full-capacity population across all supported slots
  • Validated compatibility with the Supermicro H13SVW-NT-OS2 motherboard for guaranteed recognition

Targeted server upgrade

This 192GB kit delivers two 96GB DDR5 RDIMMs built for the Supermicro H13SVW-NT-OS2 motherboard. Each module runs at 4800 MT/s with CL40 latency at 1.10V. Registered ECC circuitry and 2Rx4 organisation satisfy the board's population rules for full-capacity operation.

Thermals noise and power

Bare modules without heat spreaders rely on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller while ECC corrects single-bit errors in flight. The 1.10V operating voltage keeps per-module power draw low in densely populated configurations.

When the jump pays off

Systems running at lower capacity or speed that hit memory bottlenecks in virtualisation or database workloads benefit from the 192GB ceiling. Buyers who need more than two DIMM slots or a different form factor cannot use this kit.

Questions about this item

How do I install these 288-pin RDIMM modules in my Supermicro H13SVW-NT-OS2 motherboard, and what step is commonly missed?

Power off the server, open the chassis, locate the DDR5 slots, and align each module's notch with the slot key before pressing firmly until both clips lock. The step often missed is checking the motherboard manual for the exact DIMM population order required for 2Rx4 registered memory to initialise at 4800 MT/s.

What maintenance or replacement will this 192GB kit need over its service life?

No routine maintenance is required for these registered ECC DDR5 modules. They have no heat spreaders or moving parts. Replacement is only necessary if a module fails, which is covered by the manufacturer's lifetime replacement warranty.

What limit appears first when this memory runs at sustained load in a fully populated configuration?

The registered buffer and ECC logic add a small latency overhead, so the CL40 timing at 1.10V is the primary limit you will observe under continuous heavy workloads rather than thermal throttling, since the modules operate without heat spreaders at standard DDR5 voltage.
