64GB DDR5 4800 ECC RDIMM

This 64GB DDR5 4800 ECC RDIMM module is built for servers and workstations that require registered, error-correcting memory. It operates at 4800MHz with a CAS latency of 40 and runs at the standard 1.10V voltage. The module uses Micron chipset components in a 2Rx4 configuration.

DDR5 4800 registered interface limits

The DDR5 4800 standard delivers 38400 MB/s bandwidth per module through the 288-pin RDIMM interface. Registered buffering adds a clock cycle of latency to stabilise heavy loads across multiple slots. ECC function corrects single-bit errors but requires platform support to activate. Speed is fixed at 4800MHz without overclocking headroom on this module.

Check motherboard DDR5 RDIMM support

Verify that your motherboard accepts 288-pin DDR5 RDIMM modules and supports 64GB single-module capacity. Confirm the CPU and chipset enable ECC and registered memory operation. Consult the system manual for correct slot population rules and maximum total memory per channel. Ensure BIOS is updated for DDR5 4800 compatibility.

Questions about this item

Should I choose the single 64GB module or a different capacity?

This listing is for one 64GB module; select the quantity needed to reach your server's total memory target.

What does the 4800MHz speed mean for my server's actual throughput?

The DDR5-4800 rating delivers up to 38400 MB/s peak bandwidth per module when the platform runs at the rated data rate.

How does the 288-pin RDIMM interface limit compatibility?

The 288-pin DDR5 RDIMM form factor fits only DDR5 server and workstation boards that support registered ECC memory.
