16GB DDR4 ECC UDIMM for server upgrades

This 16GB DDR4 2400MHz ECC UDIMM module provides error-correcting memory for compatible server and workstation systems. It operates at 1.20V with CL17 latency using a 2Rx8 rank configuration. The unbuffered design fits standard 288-pin DIMM slots in supported platforms.

Replaces IBM-Lenovo 01KN325 and 01KN327 modules

This module serves as a compatible replacement for IBM-Lenovo part numbers 01KN325, 01KN327, 4X70G88326, 4X70G88334 and 4X70P26063. The upgrade is worthwhile when your system requires ECC UDIMM memory and has available DDR4 slots supporting 2400MHz operation. Verify your platform specifications before installation.

Sustained workload stability with ECC protection

Under continuous operation the ECC function detects and corrects single-bit errors to maintain data integrity during extended server tasks. Major brand chips and quality assurance testing support reliable performance at the rated 2400MHz speed. The 1.20V standard voltage helps maintain consistent thermal behaviour during prolonged use.

Questions about this item

Does this 288-pin DDR4 DIMM fit a standard server motherboard slot?

Yes, the 288-pin DDR4 UDIMM form factor matches the standard unbuffered DIMM slot used in compatible servers and workstations.

What is the correct way to seat this 1.20V ECC module so the error-correction works?

Align the notch with the slot key, press straight down until both retention clips click, and verify the system BIOS reports ECC active after boot.

When should I expect to replace this 16GB 2Rx8 module in a 24/7 server?

DDR4 ECC UDIMMs typically run for years; plan replacement only if memory diagnostics report correctable errors rising or the system fails POST.
