  • 128 GB capacity with 2 x 64 GB modules for maximum server density
  • DDR5 4800 speed rated at PC5-38400 for high bandwidth throughput
  • Registered ECC RDIMM design corrects single-bit errors and stabilises fully populated slots
  • 1 V operation at CL40 latency matches the motherboard memory controller exactly
  • 288-pin 2Rx4 form factor verified for Supermicro H13SSL-N compatibility

Exact-match server upgrade

This 128GB kit delivers two 64GB DDR5 registered ECC RDIMMs built for the Supermicro H13SSL-N motherboard. The modules run at 4800 MT/s with CL40 timing at 1.1V, matching the exact rank, voltage and timing the memory controller expects for full-capacity recognition.

DDR5 registered ECC limits

Registered architecture buffers address and command signals so every slot can be populated at full capacity without overloading the controller. ECC corrects single-bit errors on the fly, preventing silent data corruption that would otherwise crash production workloads. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function.

Replaces partial or mismatched kits

Upgrading from a smaller capacity kit or mixed-rank modules removes population-rule conflicts and restores full-channel bandwidth. The jump is worth it when your workload needs the full 128GB at rated speed and you cannot tolerate unplanned reboots caused by uncorrectable memory errors.

Questions about this item

Should I buy the 128 GB kit or a different capacity?

This exact-match kit provides 128 GB as two 64 GB modules, matching the Supermicro H13SSL-N memory-population rules for full-capacity recognition at rated speed.

What does the DDR5-4800 rating mean once the modules are installed in my server?

The memory controller will run each module at 4800 MT/s with CL40 latency and 1.10 V, delivering the full PC5-38400 bandwidth the board expects.

How does the 288-pin RDIMM interface limit what I can do with this memory?

The registered 288-pin RDIMM form factor is required by the H13SSL-N; it offloads the controller so every slot runs fully populated at full capacity with ECC protection.
