16 GB DDR4 RDIMM for servers

This 16 GB DDR4 module runs at 2933 MHz with CL21 latency and 1.20 V operation. It is a registered DIMM with ECC parity, built for Intel Xeon platforms that require error-correcting memory. The single 1Rx4 rank plugs into any standard 288-pin DDR4 server slot.

Sustained throughput with register buffering

The on-module register chip directs every command and controls data flow, preventing signal loading during continuous read-write cycles. ECC parity detects and corrects single-bit errors before they corrupt workloads, keeping databases and virtualisation hosts stable over long periods. All components pass 100 % module-level testing to mission-critical server standards.

288-pin form factor fits OEM chassis

The standard DIMM height clears typical server heatsinks and airflow ducts without special clearance planning. Registered signalling reduces electrical load on the memory controller, allowing higher population densities across all channels. Compatibility with OEM servers and OEM warranties means the module can be added to supported systems without voiding existing coverage.

Perguntas sobre este artigo

Does the 1.20 V DDR4 2933 registered module add noticeable heat or fan noise when running continuously in a server?

The module operates at the standard 1.20 V DDR4 voltage, so its thermal contribution is comparable to other DDR4 RDIMMs and does not require extra cooling beyond normal server airflow.

What must the system already provide for this 288-pin DDR4 2933 ECC registered DIMM to function?

A server motherboard with DDR4 RDIMM slots, a memory controller that supports ECC and registered modules, and a CPU or chipset qualified for DDR4 2933 operation.

Can this CL21 2933 MHz registered stick share channels with older DDR4 registered modules at a lower common speed?

Mixed-speed DDR4 RDIMMs will usually run at the lowest installed frequency, but stability depends on the platform's memory controller and BIOS; verify with the server vendor's qualified-vendor list.
