32 GB DDR4 2933 Registered ECC Module

This 32 GB DDR4 2933 module uses a 288-pin form factor and operates at 1.20 V. It is built with ECC and registered buffering for data integrity in server workloads. The CAS latency is CL21 with 21-21-21 timings. The dual-rank 2Rx4 organisation suits high-density configurations.

Practical Limits of DDR4 2933 Registered ECC

The module runs at the DDR4 2933 (PC4 23400) data rate with fixed CL21 timings. Registered buffering adds one clock cycle of address/command delay versus unbuffered DIMMs. ECC function requires a memory controller that supports error-correcting code on every transaction. Dual-rank 2Rx4 density may restrict the number of DIMMs per channel on some platforms.

Check Platform Requirements Before Ordering

Verify that your server motherboard and CPU memory controller accept DDR4 2933 registered ECC DIMMs. Confirm the maximum supported capacity per slot and the total number of ranks allowed per channel. Ensure the BIOS can initialise 2Rx4 modules at the rated speed and voltage. Registered ECC modules will not function in consumer desktop boards that lack ECC and registered support.

Questions about this item

Should I pick a single 32GB module or multiple smaller sticks?

This is a single 32GB DDR4 2933 module; add identical sticks to fill your server's channels and reach the total capacity you need.

What does the 2933 speed rating deliver in my server?

It runs at 2933 MT/s with CL21 timing at 1.20V, giving the rated bandwidth when the platform supports DDR4 2933.

How does the registered ECC design affect compatibility?

The 2Rx4 registered ECC module requires a server board that supports registered DDR4 memory; it will not work in standard desktop chipsets.
