A 64 GB registered 288-pin DIMM running at 2933 MT/s for server memory upgrades

  • 64 GB capacity supports large datasets and virtual machines
  • Registered design improves signal integrity for server stability
  • 2933 MT/s bus speed delivers high throughput for demanding workloads
  • 288-pin DIMM form factor fits standard server memory slots
  • 2Rx4 organisation optimises rank density for maximum module capacity

64GB Registered PC4-2933 DIMM

This 64GB registered DIMM provides high-capacity memory for servers and workstations that require error-correcting stability. It operates at a 2933 MT/s bus speed using a 288-pin form factor.

Suited for ECC memory expansion.

This module suits administrators upgrading registered memory configurations in compatible 288-pin slots. Builders needing non-ECC unbuffered memory for desktop or consumer laptops should look at a different product class.

2Rx4 organisation for high-density registered slots

The dual-rank by four organisation packs 64GB into a single module for dense registered DIMM slots. Systems limited to single-rank modules or a lower maximum rank count per channel cannot use this part.

Questions about this item

How is the 288-pin DIMM installed, and what step do people get wrong?

Align the notch on the 288-pin edge connector with the slot key, press straight down until both retention clips click, and verify the module sits evenly; the step often missed is failing to open both clips fully before insertion.

What maintenance or replacement will the 64GB registered module need later?

No routine maintenance is required; if the system begins reporting corrected ECC errors or fails to POST, replace the module — otherwise it runs for the life of the platform.

What limit appears first on the 2933 MT/s registered DIMM under sustained load?

The JEDEC-rated 2933 MT/s data rate is the ceiling; sustained workloads cannot exceed this speed without platform overclocking support, which registered DIMMs typically do not allow.
