Exact-Match DDR5 Kit for Supermicro H14SSL-NT

This 192GB kit contains two 96GB DDR5 4800 RDIMMs built to the board's exact rank, voltage and timing requirements. Registered ECC modules offload the memory controller so every slot runs fully populated at rated speed. Designed for server administrators who need guaranteed compatibility and silent data correction.

DDR5 4800 Registered ECC Limits

The DDR5 4800 standard caps transfer rate at 4800 MT/s and the registered buffer adds one cycle of latency per command. CL40 timing at 1.1V is the JEDEC baseline, so overclocking headroom is minimal. Systems that require higher bandwidth or lower latency must choose a faster-rated module.

192GB Capacity and Population Rules

Two 96GB 2Rx4 DIMMs fill two slots and deliver 192GB of error-correcting capacity for virtualization, databases or large datasets. Adding more modules depends on the motherboard's qualified vendor list and population order, which are not covered by this kit. Buyers needing more than 192GB or a different rank configuration must verify support with the system manual.

Questions about this item

Should I pick the 2 x 96 GB kit or a single 192 GB module for my Supermicro H14SSL-NT?

The kit is sold as two 96 GB modules. The board uses 288-pin DDR5 RDIMM slots and its population rules expect matched pairs, so the 2 x 96 GB kit is the correct choice for full capacity and proper channel interleaving.

What does DDR5 4800 CL40 mean for real-world throughput on this server?

The modules run at 4800 MT/s with a CAS latency of 40 cycles. In a registered ECC configuration the memory controller drives every slot at that rated speed, delivering the full PC5-38400 bandwidth while ECC corrects single-bit errors on the fly.

How does the 288-pin RDIMM interface limit what I can install?

The Supermicro H14SSL-NT only accepts 288-pin DDR5 RDIMMs. UDIMMs, SODIMMs or any other form factor will not fit, and the registered buffer is required for the board to run all slots fully populated at 4800 MT/s.
