Capacity & Fit

This 96GB kit supplies two 48GB DDR5 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSL-NT memory controller expects. The modules are recognised at full capacity and run at their rated 6400 speed without manual tuning.

Upgrade Path

It replaces slower DDR5 or partially populated configurations that leave slots empty or force the controller to down-clock. The jump is worth it when your workload needs the full 96GB at CL52 1.1V across every populated channel for maximum throughput.

Sustained Operation

Registered buffering offloads the memory controller so all slots stay stable at full population during continuous operation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots that would otherwise halt production workloads.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SSL-NT motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the H13SSL-NT requires; it is not a UDIMM or SODIMM and matches the board's physical slot keying.

What population order should I follow when installing both 48 GB modules on the H13SSL-NT?

Consult the motherboard manual for the approved DIMM population sequence; server boards often require specific slots to be filled first for full 96 GB recognition at DDR5-6400.

Do these modules need active cooling or heat-spreader maintenance over time?

The modules ship without heat spreaders and run at 1.1 V; ensure adequate chassis airflow per the server vendor's guidelines, but no spreader cleaning or thermal-pad replacement is required.
