Server DDR4 module for certified Supermicro systems

The Supermicro MEM-DR412L-SL01-ER32 is a 128GB DDR4 3200 ECC registered DIMM built for Supermicro UP and DP server platforms. It targets administrators expanding memory in listed SSG-520P, SSG-540P, SSG-620P or SSG-640P chassis where vendor qualification is required.

Registered ECC with 3DS stacking

The single specification that decides fit is the registered ECC 3DS RDIMM interface combined with the exact Samsung M393AAG40M32-CAE part number. Only systems validated for this module’s rank structure and SPD profile will initialise it correctly.

128GB per slot at 3200 MT/s

Each module delivers 128GB at DDR4 3200 (PC4-25600) CL22 1.20V, using 2Rx4 3DS organisation. Capacity scales with the number of populated slots on the qualified platform; headroom ends when the server’s maximum DIMM count or memory-controller limit is reached.

Questions about this item

What does the 3200 MT/s speed mean once the module is installed in a server?

The module runs at 3200 MT/s when the memory controller and BIOS support that data rate; otherwise it operates at the highest speed the platform allows.

How does the PC4-25600 designation limit real-world bandwidth?

PC4-25600 is the JEDEC name for DDR4-3200; peak bandwidth per module reaches 25600 MB/s only when the controller runs the full data rate on a populated channel.

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

It fits a standard 288-pin DDR4 DIMM socket; the registered design adds a buffer chip, so verify the motherboard supports registered ECC modules before installation.
