Rank 2Rx8

  • 32 GB capacity handles large server workloads
  • DDR5 4800 MT/s speed increases data throughput
  • CL40 latency reduces memory access delay
  • ECC support detects and corrects data errors
  • 10 V operation lowers power consumption

Server DDR5 ECC SODIMM

This 32 GB DDR5 module runs at 4800 MT/s with CL40 timings and on-module ECC. It uses a 262-pin SO-DIMM form factor and operates at 1.10 V. The dual-rank 2Rx8 layout is unbuffered and includes an Intel XMP 2.0 profile for automatic configuration.

Upgrade from slower DDR5 or non-ECC SODIMMs

The jump is worthwhile when data integrity matters and the platform supports DDR5-4800 ECC memory. Systems limited to lower speeds or lacking ECC capability will not benefit from the error-correction feature. Buyers who need registered DIMMs or capacities beyond 32 GB per slot should look elsewhere.

DDR5 SO-DIMM electrical and physical limits

The 262-pin connector and 1.10 V signalling define the mechanical and electrical envelope. Unbuffered operation means the memory controller drives every device directly, which can limit the maximum number of modules per channel. Platforms without DDR5 SO-DIMM slots or ECC support in the BIOS cannot use this module.

Questions about this item

Does this 262-pin DDR5 SO-DIMM fit a standard notebook memory slot?

Yes, the 262-pin DDR5 SO-DIMM form factor matches the standard DDR5 SO-DIMM slot found in compatible notebooks and embedded boards.

What BIOS setting is needed to run this module at its rated 4800 MT/s CL40?

Enable the Intel XMP 2.0 profile in the BIOS; the module stores the 4800 MT/s, CL40-39-39, 1.10 V profile there. Without XMP enabled, the system will fall back to a lower JEDEC speed.

Will the dual-rank 2Rx8 organisation affect future upgrades?

Each module presents two ranks to the memory controller. Populate remaining slots with identical 2Rx8 modules to keep rank count per channel balanced and avoid exceeding the platform's maximum ranks per channel.
