Speed 4800MHz

  • 64 GB capacity supports large workloads
  • DDR5 4800 speed matches server memory controller
  • CL40 CAS latency at rated 1.1 V
  • 2Rx4 registered ECC corrects single-bit errors
  • 288-pin RDIMM fits Supermicro H13SRH motherboard

Targeted Server Upgrade

This 64GB DDR5-4800 ECC registered DIMM is built for the Supermicro H13SRH motherboard. It delivers the exact rank, voltage and timing the board's memory controller expects so the full capacity is recognised at rated speed.

Pre-Installation Checks

Verify your system manual for supported capacities, approved population order and installation steps before ordering. The board requires 288-pin registered DIMMs; unbuffered or SODIMM modules will not fit or function.

Replaces Slower Or Smaller DDR5

The jump is worth it when your current DDR5 modules run below 4800MT/s or total capacity limits your workload. Registered ECC architecture keeps every slot stable at full population while correcting single-bit errors on the fly.

Questions about this item

Does the kit include only the 64GB DDR5 4800 CL40 ECC RDIMM module or are cables or brackets also supplied?

The package contains the single 64GB DDR5 4800MHz PC5-38400 2Rx4 1.1V CL40 288-pin ECC Registered RDIMM and nothing else.

Should I choose this 64GB 2Rx4 CL40 RDIMM or a different capacity or rank for the Supermicro H13SRH?

This exact 64GB 2Rx4 CL40 Registered ECC DDR5 RDIMM matches the Supermicro H13SRH memory controller requirements for full-capacity recognition at rated speed.

What does the 4800MHz PC5-38400 rating mean once the module is installed in the H13SRH?

The module will run at DDR5 4800 with CL40 latency and 1.1V, delivering the bandwidth and error-correction the board expects when fully populated.
