32 GB DDR3L ECC Registered DIMM

This 32 GB DDR3L 1066 PC3L-8500 CL7 4Rx4 240-pin 1.35 V ECC Registered DIMM is a server-grade memory module built for workstations, servers, NAS systems and routers. It conforms to JEDEC and RoHS standards and is tested to meet or exceed OEM specifications. The registered design with ECC provides error correction and signal buffering required by compatible platforms.

Suits registered-ECC platforms only

This module is intended for systems that specifically support DDR3L ECC Registered memory at 1066 MHz with a 4Rx4 organisation. It will not operate in computers that require unbuffered non-ECC DDR3L or DDR3, nor in platforms that cannot address 4Rx4 registered DIMMs. Buyers whose hardware calls for unbuffered memory, different speeds, other voltages or alternative rank configurations should select a different part.

4Rx4 registered organisation

The 4Rx4 rank configuration is the critical attribute that determines compatibility. Only motherboards and memory controllers qualified for 4Rx4 DDR3L Registered ECC at 1.35 V can use this 32 GB DIMM. Verify the platform documentation for this exact organisation before purchasing.

Questions about this item

How much capacity does the 32GB module add to a server?

The single module provides 32GB of DDR3L ECC registered memory, expanding total system capacity by that amount when installed in a compatible slot.

What does the PC3L-8500 1066MHz rating limit in practice?

PC3L-8500 1066MHz CL7 sets the maximum data rate at 1066 MT/s with CAS latency 7; the memory controller will not run this module faster than that specification.

Will the 240-pin DIMM fit my workstation board?

The module uses the standard 240-pin DDR3L RDIMM form factor, so it fits any DDR3L registered DIMM slot that accepts 4Rx4 modules at 1.35V.
