256GB DDR4 2933 ECC RDIMM kit

This kit provides 256GB of DDR4 2933 registered ECC memory across eight 32GB modules. It is built for servers and workstations that require error-correcting registered DIMMs for data integrity and high-capacity workloads. The single-rank x4 organisation supports dense memory configurations on compatible platforms. Desktop and laptop systems cannot use these modules.

Registered ECC with major-brand chips

Each module uses major-brand DRAM chips and operates at the standard DDR4 voltage of 1.20V. Registered buffering reduces electrical load on the memory controller, while on-board ECC detects and corrects single-bit errors to protect critical data. The CL21 latency rating is specified for the 2933 MT/s speed grade.

Verify DDR4 RDIMM support and population rules

Check your system manual to confirm it accepts DDR4 288-pin registered ECC DIMMs and supports 32GB single-rank x4 modules at 2933 MT/s. Some platforms limit total capacity per channel or require specific slot-filling sequences for large kits. Ensure the BIOS is current before installation.

Questions about this item

Will the 288-pin DDR4 modules need any firmware updates or thermal-pad replacements during their service life?

No firmware updates or thermal-pad replacements are required; the modules have no heat spreader and run at standard 1.20 V, so they operate maintenance-free once installed.

What electrical or thermal limit appears first when the 1Rx4 registered DIMMs run at 2933 MHz continuously?

The 1.20 V DDR4 standard voltage is the primary electrical ceiling; sustained loads stay within this spec, and the registered buffer helps keep signal integrity within JEDEC limits.

How much heat and noise do the eight 32 GB sticks generate when the server runs all day?

With no heat spreaders and a low 1.20 V operating voltage, the modules add minimal heat to the chassis airflow and produce zero acoustic noise themselves.
