8GB DDR4 2933 ECC Registered Module

This 8GB DDR4 module runs at 2933 MT/s with CL21 timings and 1.20V voltage. It uses a 288-pin registered design with ECC for error correction. The single-rank 1Rx8 organisation suits server platforms that require registered memory.

Suited for servers needing registered ECC DIMMs

The module fits systems that specifically call for registered DDR4 with ECC. It is not for desktops or workstations that only accept unbuffered non-ECC memory. Buyers who need higher capacities per slot or lower latencies should look at other configurations.

Verify motherboard supports registered ECC DDR4

Check that your server board lists registered ECC DDR4 2933 support in its qualified vendor list. Confirm the number of available 288-pin slots and the maximum memory per channel. Ensure the system BIOS is current for full compatibility.

Questions about this item

Does my server need a 288-pin DDR4 slot that supports registered ECC modules?

Yes, this 8 GB stick is a 288-pin DDR4 2933 registered ECC DIMM, so the motherboard must accept registered ECC memory in a standard DDR4 slot.

Can I mix this CL21 2933 MT/s module with slower DDR4 ECC registered DIMMs already in the system?

The server will run all installed modules at the speed and timings of the slowest DIMM, so this stick will downclock to match your existing memory.

How do I confirm the module is running at 2933 MT/s with CL21 timings after installation?

Check the BIOS memory information or a tool such as dmidecode; it should report DDR4-2933, PC4-23400, CAS latency 21 and registered ECC operation.
