128 GB DDR4 ECC RDIMM for servers

This NEMIX RAM module delivers 128 GB of registered DDR4 memory at 3200 MT/s. It uses a 4Rx4 organisation with ECC and operates at 1.20 V. The 288-pin RDIMM form factor fits compatible server and workstation motherboards that support registered ECC DIMMs.

Registered DDR4 tops out at 3200 MT/s and 1.2 V

The DDR4 standard caps registered DIMM speed at 3200 MT/s with a nominal 1.2 V supply. Higher frequencies or lower voltages are not defined for this generation. Systems that require faster memory must move to a newer platform that supports DDR5.

4Rx4 rank layout decides motherboard compatibility

The 4Rx4 rank configuration determines whether the memory controller can address the full 128 GB capacity. Some server boards limit the number of ranks per channel or do not support 4Rx4 modules. Verify the motherboard's qualified vendor list before purchase.

Questions about this item

Should I pick the 128GB single module or look for multiple smaller sticks?

This listing is a single 128GB 288-pin DDR4 RDIMM; choose it when your server board has a free slot and supports 4Rx4 registered ECC modules.

What does the DDR4 3200 PC4-25600 rating deliver once installed?

The module runs at 3200 MT/s with CL22 latency at 1.20V, giving the rated PC4-25600 bandwidth when the platform enables that speed.

How does the registered ECC RDIMM interface affect compatibility and capacity limits?

The 4Rx4 registered ECC design requires a server or workstation motherboard that supports registered DDR4 DIMMs; it will not work in standard desktop boards.
