Server-Ready ECC RDIMM

This 16 GB DDR4 registered DIMM operates at 2933 MHz with CL21 latency and 1.20 V. It uses a 2Rx8 organisation and major-brand chips to deliver error-correcting stability for supported server and workstation platforms. The module is a direct replacement for the IBM-Lenovo 4ZC7A62799 part number.

Compatibility-Critical Upgrade

It suits administrators expanding memory in qualified IBM-Lenovo systems that require ECC RDIMM modules at this speed and rank configuration. Builders needing unbuffered UDIMMs, different capacities, higher frequencies or non-ECC memory should look elsewhere because this module will not function in those roles.

Verified Module Only

The package contains the single tested 288-pin DIMM with no extra cables, brackets or software utilities. Quality-assurance screening and lifetime warranty coverage are supplied by the manufacturer, but they do not alter the hardware specification or installation requirements of the module itself.

Questions about this item

Does my server need DDR4 288-pin RDIMM slots to use this 16GB 2933MHz ECC module?

Yes, this is a DDR4 288-pin registered DIMM; your motherboard must support DDR4 RDIMM slots and ECC memory for it to function correctly.

Can I mix this 2Rx8 CL21 1.2V stick with existing 1Rx8 DDR4 RDIMMs in the same channel?

Mixing ranks is possible if the platform supports it, but all modules will run at the lowest common speed and highest CAS latency; check your system's qualified vendor list for validated 2Rx8 configurations.

How do I confirm the module is running at 2933MHz with ECC active after installation?

Enter the BIOS or UEFI and verify the memory frequency shows 2933 MT/s, the voltage reads 1.20V, and ECC status reports as enabled or active for the installed 16GB DIMM.
