Axiom A7187321-AX 32 GB DDR3 1866 MHz 240-pin LRDIMM memory card

SKU CH-RWBF-90QS5 MPN A7187321-AX

32 GB DDR3 LRDIMM running at 1866 MHz with a 240-pin interface and 1.50 V operation

  • 32 GB capacity supports memory-intensive workloads
  • 1866 MHz DDR3 speed enables responsive data handling
  • LRDIMM architecture reduces electrical load for stable operation
  • 240-pin DDR3 interface ensures broad server compatibility
  • 50 V operating voltage matches standard DDR3 power requirements

Axiom 32 GB DDR3-1866 LRDIMM

The Axiom A7187321-AX is a 32 GB DDR3 SDRAM module built to the DDR3-1866/PC3-14900 standard. It operates at 1866 MHz with a 1.50 V supply and uses a 240-pin LRDIMM form factor. This memory card targets servers and workstations that require high-density registered memory.

Suited for DDR3 platforms needing maximum capacity

Systems designed for DDR3 LRDIMM modules running at 1866 MHz can use this part to reach 32 GB in a single socket. Buyers whose motherboards accept only UDIMM or RDIMM formats cannot install this LRDIMM unit. Builders working with newer memory architectures should look elsewhere.

240-pin LRDIMM interface

The 240-pin LRDIMM interface is the single specification that decides fitment; the module will only function in slots wired for load-reduced DDR3 memory. Verify that your platform supports LRDIMM operation before purchase.

Questions about this item

Will the 240-pin LRDIMM module fit my server's DDR3 slots?

The module uses the standard 240-pin DDR3 LRDIMM form factor; it fits any slot wired for that pin count and module height.

What is the correct way to seat this 32 GB LRDIMM so it posts on first boot?

Align the key notch with the slot ridge, press straight down until both side clips click, and verify the module sits evenly with no gap.

How do I know when this DDR3-1866 stick should be replaced?

Replace it if memtest86 reports uncorrectable errors, the system fails to train at 1866 MHz, or the module shows physical damage.
