128 GB DDR5 5600 ECC RDIMM for SuperMicro B13DEE

This registered DIMM delivers 128 GB of DDR5 5600 memory with ECC and a CL46 latency. It is built for the SuperMicro B13DEE motherboard in server and workstation deployments. The single-module kit suits administrators expanding capacity in compatible platforms.

Thermals noise and power at 1.1 V

Operating at 1.10 V, the module runs within standard DDR5 server power limits without a heat spreader. Registered buffering reduces electrical load on the memory controller during sustained workloads. Passive cooling in a chassis with adequate airflow keeps temperatures stable.

4Rx4 organisation decides fit

The 4Rx4 rank configuration determines whether the motherboard can address the full 128 GB in a single slot. Systems limited to lower rank counts will not recognise the module. Verify the B13DEE memory population rules before purchase.

Questions about this item

How do I install the 288-pin DDR5 RDIMM in the SuperMicro B13DEE, and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 128GB module is detected at 5600 MT/s with ECC active.

What maintenance or replacement will this 4Rx4 registered ECC module need over its service life?

No scheduled maintenance is required; the module has no heat spreader, so keep server airflow clean, and rely on ECC to correct single-bit errors — replace only if the system logs uncorrectable errors or the module fails POST.

What limit appears first when this 1.1V CL46 kit runs sustained workloads on the B13DEE?

The CAS latency of CL46 at 5600 MT/s sets the timing ceiling, while the 1.1V operating voltage and 4Rx4 density constrain thermal headroom before any frequency throttling occurs.
