Server Memory Module

This 32GB DDR4 ECC RDIMM is built for Supermicro servers and workstations that require registered memory with error correction. It delivers 3200MHz speed at CL22 latency and operates at the standard 1.2V voltage for stable enterprise workloads.

Suited For And Limits

This module suits administrators upgrading Supermicro platforms validated for the MEM-DR432L-HL02-ER32 part number. Buyers needing unbuffered UDIMMs, non-ECC memory, or capacities other than 32GB per module should look at different products.

Deciding Specification

The registered ECC RDIMM form factor with 2Rx4 organisation and Supermicro certification is the single specification that determines whether this part will function in your qualified system configuration.

Questions about this item

What speed does the DDR4 3200 interface actually run at in a typical server?

The module is rated for DDR4 3200 (PC4-25600). In practice it will operate at the highest speed the CPU and motherboard support, up to 3200 MT/s.

What physical slot and clearance does this 288-pin RDIMM require?

It fits a standard DDR4 288-pin RDIMM slot. The registered design adds a buffer chip, so verify the motherboard supports registered DIMMs and that heatsink clearance is adequate.

How is the module installed and what step is often missed?

Power down the server, open the chassis, align the notch with the slot key, press firmly until both latches click. The step often missed is confirming the system detects the full 32 GB and ECC mode in BIOS before closing the case.
