Green 288-pin DDR4 UDIMM module with black chips

Axiom

Axiom 4ZC7A08696-AX 8GB DDR4-2666 ECC UDIMM server RAM

SKU CH-6AWD-A8M25 MPN 4ZC7A08696-AX

8GB DDR4-2666 ECC UDIMM server memory runs at 2666 MHz with 1.20 V operation

  • 8 GB DDR4 capacity expands server memory headroom
  • 2666 MHz DDR4-2666 speed processes data faster
  • ECC error correction protects data integrity in critical workloads
  • 20 V low-voltage operation reduces power draw per module
  • 288-pin UDIMM form factor fits standard unbuffered server slots

Axiom 8GB DDR4-2666 ECC UDIMM

This 8 GB DDR4 module adds ECC error correction to compatible Lenovo server platforms. The unbuffered 288-pin UDIMM format fits standard DDR4 slots in supported systems. It targets administrators who need reliable memory for multi-application workloads.

TruDDR4 2666 MHz at 1.20 V

Rated at 2666 MHz with PC4-21300 bandwidth, the stick operates at 1.20 V for efficient power draw. The TruDDR4 designation indicates Lenovo-qualified validation for consistent signal integrity. ECC circuitry detects and corrects single-bit errors during daily operation.

Upgrade from non-ECC or lower-speed DDR4

Replacing non-ECC UDIMMs adds data-integrity protection for critical services. Moving up from slower DDR4 frequencies increases throughput for concurrent tasks. The jump is worthwhile when the platform supports 2666 MHz ECC unbuffered memory and the workload demands error correction.

Questions about this item

What speed does the DDR4-2666 interface actually run at?

The module operates at 2666 MHz, matching the PC4-21300 data rate.

Will the 288-pin UDIMM fit my server's memory slots?

It requires a standard 288-pin DDR4 UDIMM slot with 1.20 V support.

How do I install this ECC UDIMM and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify the new capacity in the BIOS or OS.
