Exact-Match Server Upgrade

This 192GB kit contains six 32GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.10V operation. It is built as a direct replacement for the Supermicro H13SVW-NT-OS1 motherboard, matching the registered ECC 2Rx8 layout that the platform expects for full-capacity recognition.

Sustained Enterprise Stability

Registered buffering reduces electrical load on the memory controller, allowing all slots to remain populated at rated speed during continuous workloads. On-die ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise halt production systems.

DDR5 Platform Constraints

The 288-pin RDIMM form factor is mandatory for this motherboard; UDIMM or SODIMM modules will not seat or function. Population rules defined by the board firmware dictate which slots must be filled first, so the manual must be consulted before installation to avoid a no-post condition.

Questions about this item

How much heat and power will the six 32 GB DDR5-4800 modules generate when the server runs continuously?

Each module operates at 1.1 V with a CL40 2Rx8 layout; the registered design shifts electrical load off the memory controller, so the kit runs within standard DDR5 thermal limits for fully populated channels.

What motherboard and firmware must already be present for this 192 GB kit to function?

The kit is validated for the Supermicro H13SVW-NT-OS1 motherboard; the board must support 288-pin registered DDR5 DIMMs and its BIOS must recognise 2Rx8 32 GB density modules at 4800 MT/s.

Will these DDR5-4800 RDIMMs run at rated speed if I keep older DDR5 modules of a different speed in the remaining slots?

The memory controller will negotiate a single common frequency; mixing speeds forces all populated channels to the lowest supported rate, so the 4800 MT/s modules would down-clock to match the slower DIMMs.
