512GB DDR5 ECC RDIMM kit for Supermicro servers

This kit provides 512GB of DDR5 registered ECC memory across four 128GB modules built for Supermicro B13DEE motherboards. It targets administrators who need maximum registered capacity in a single validated package for database, virtualisation or AI workloads.

1.10V 288-pin registered modules without heat

Each 4Rx4 module runs at 1.10V and uses a standard 288-pin DDR5 RDIMM form factor. The absence of heat spreaders means airflow across the motherboard must be sufficient to keep the DRAM within thermal limits under sustained load.

Verify B13DEE memory population rules

Confirm the motherboard firmware revision lists 5600MT/s operation with four 4Rx4 DIMMs populated. Check the platform documentation for any slot-filling sequence or maximum rank-per-channel limits that could prevent the full 512GB from being recognised.

Questions about this item

What DDR5 speed and CAS latency does this 512GB kit run at?

The kit operates at DDR5 5600 with a CAS latency of CL46, delivering PC5-44800 bandwidth across the four modules.

What physical slot and form factor do these modules require?

Each 128GB module is a 288-pin DDR5 RDIMM; the motherboard must provide four registered DIMM slots that accept 4Rx4 ECC modules.

How are the modules installed and which step is often missed?

Power down the server, open the chassis, align each module's notch with the 288-pin slot, press firmly until the retention clips click, then verify in BIOS that all four ranks are detected at 5600 MT/s.
