192GB DDR5 ECC RDIMM kit for Supermicro H13SSL-N

This 12-module kit delivers 192GB of DDR5-4800 registered ECC memory built to the exact rank, voltage and timing the H13SSL-N memory controller expects. Each 16GB RDIMM is a single-rank 1Rx8 part operating at 1.1V with CL40 latency. The 288-pin registered form factor matches the board's slot requirements so the full capacity is recognised at rated speed.

Sustained-load behaviour

Registered buffering offloads the memory controller, allowing all twelve slots to remain fully populated at the rated 4800 MT/s without downclocking. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous server workloads. The 1.1V operating voltage keeps power draw consistent across the full kit under prolonged utilisation.

DDR5-4800 PC5-38400 interface limits

The DDR5-4800 standard caps transfer rate at 4800 MT/s and bandwidth at PC5-38400, so this kit cannot exceed those figures regardless of motherboard capabilities. CL40 latency is fixed by the module's SPD profile. Population rules, maximum supported capacity per slot and required DIMM installation order are defined by the Supermicro H13SSL-N manual and must be followed for stable operation.

Questions about this item

How much heat and power draw should I expect from this 192GB DDR5 4800 kit running continuously at 1.1V?

At 1.1V the 12 modules draw minimal power, keeping sustained heat low even with all 288-pin slots populated on the Supermicro H13SSL-N.

What motherboard and CPU combination is required for this 12x16GB DDR5 RDIMM kit to function?

A Supermicro H13SSL-N motherboard with a compatible DDR5 server processor is required; the board must support registered ECC RDIMMs at 4800 MT/s.

Can I mix these CL40 1Rx8 DDR5 modules with older DDR5 sticks I already have in the H13SSL-N?

Mixing ranks or timings is not recommended; the board's memory controller expects identical 1Rx8 CL40 modules across all populated channels for stable operation.
