SKU CH-401H-HSQRN MPN 4ZC7A08708-AX

16 GB DDR4-2933 ECC RDIMM server memory with 1.2 V operation and 288-pin design

  • 16 GB capacity handles heavy workloads
  • ECC RDIMM protects data integrity in servers
  • 2933 MT/s DDR4 speed accelerates applications
  • 2 V operation reduces power draw
  • 288-pin DDR4 form factor fits standard slots

Axiom 16GB DDR4-2933 ECC RDIMM

This Axiom 4ZC7A08708-AX module provides 16GB of DDR4 server memory. It operates at 2933MT/s with a PC4-23466 speed rating and CL21 latency. The 288-pin RDIMM runs at 1.2V and includes ECC for data integrity. It is built for compatible Lenovo server platforms requiring registered memory.

Suited for registered ECC DDR4 slots

This module fits servers that require 288-pin DDR4 RDIMMs with ECC support. It is not for systems limited to UDIMM or non-ECC memory. Buyers needing different capacities, speeds or form factors such as LRDIMM should look elsewhere. Systems locked to lower voltages or proprietary memory will not accept this part.

2933MT/s registered ECC speed

The decisive specification is the 2933MT/s data rate combined with ECC RDIMM registration. The motherboard and CPU memory controller must support this exact speed and registered topology. Verify the platform qualified vendor list for 4ZC7A08708-AX compatibility before purchase. Mismatched speed or module type will prevent boot or reduce stability.

Questions about this item

Does this 288-pin DDR4 RDIMM need a motherboard slot that accepts registered ECC memory?

Yes, the module is an ECC RDIMM, so the system must support registered error-correcting DDR4 memory in a 288-pin slot.

Can this CL21 1.2 V module share a channel with existing DDR4 RDIMMs that have different timings?

The DIMM runs at 2933 MT/s with CL21 at 1.2 V; the memory controller will negotiate a common speed and timing for all modules in the channel.

How can I confirm the DIMM is detected at 2933 MT/s with ECC active after installation?

Check the BIOS memory information or run a hardware utility — it should report 16 GB, 2933 MT/s, PC4-23466 and ECC enabled.
