Axiom F1F33AA-AX 32 GB DDR3 1866 MHz ECC LRDIMM 240-pin 1.50 V

SKU CH-GHRG-7RE8T

32 GB DDR3 LRDIMM module runs at 1866 MHz with ECC for server stability

  • 32 GB capacity supports heavy workloads
  • 1866 MHz DDR3 speed enables fast data throughput
  • ECC protection detects and corrects memory errors
  • LRDIMM design reduces electrical load on the bus
  • 50 V operation lowers power consumption

32 GB DDR3 LRDIMM for servers

This 32 GB DDR3 LRDIMM operates at 1866 MHz with a PC3-14900 rating. The module uses a 240-pin form factor and runs at 1.50 V. ECC capability detects and corrects data errors for improved system reliability. The load-reduced design lowers electrical load on the memory bus.

Sustained throughput with reduced bus load

The LRDIMM architecture buffers address and command signals to reduce electrical load on the memory controller. This allows higher densities to run at 1866 MHz without degrading signal integrity under continuous workloads. ECC operation adds a small latency overhead while protecting data during long compute runs. The 1.50 V supply keeps power draw predictable during extended use.

Upgrades registered DDR3 configurations

This module replaces standard registered DIMMs when the platform supports LRDIMM topology and 32 GB density per slot. The jump is worthwhile when the memory controller qualifies LRDIMM at 1866 MHz and the application benefits from the larger per-slot capacity. Systems limited to registered DIMM electrical loading cannot use this module.

Questions about this item

How much heat and power should I expect from this 32 GB DDR3-1866 LRDIMM running continuously at 1.50 V?

The module is rated for 1.50 V operation at 1866 MHz; DDR3 LRDIMM designs typically run cooler than standard RDIMMs at the same voltage because the load-reduced buffer cuts electrical load on the memory bus.

What must my system already provide for this 240-pin DDR3 LRDIMM to function?

A DDR3 memory controller that supports 240-pin LRDIMM modules, ECC capability, and a 1.50 V DIMM slot are required for the module to be recognised and operate at 1866 MHz.

Can I add this PC3-14900 stick to a server that currently uses slower DDR3 ECC DIMMs?

The module will down-clock to the speed of the slowest installed DDR3 ECC DIMM, but all slots must accept 240-pin LRDIMMs at 1.50 V for the system to post successfully.
