32GB DDR3L ECC Kit for Workstations

This kit supplies 32GB of DDR3L 1600 memory in eight 4GB unbuffered UDIMMs. Each module runs at 1.35V with CL11 timing and includes ECC error correction. The 240-pin form factor fits desktop, workstation and server boards that accept DDR3L ECC unbuffered memory.

Suited for ECC-Capable Systems Only

The modules require a platform that supports DDR3L ECC unbuffered UDIMMs; standard desktop boards limited to non-ECC memory cannot use this kit. Builders expanding a compatible workstation, server or NAS will gain the full 32GB capacity across eight slots.

Deciding Specification: ECC Unbuffered DDR3L

The single detail that determines fit is the ECC unbuffered DDR3L designation at 1.35V. If the target system calls for registered, non-ECC or a different voltage, these modules will not function.

Questions about this item

Will this 240-pin DDR3L kit fit my desktop motherboard?

The kit uses 240-pin DDR3L UDIMMs at 1.35 V. Your motherboard must support DDR3L unbuffered ECC memory and have eight available slots.

Does the CL11 latency at 1600 MHz affect real-world responsiveness?

CL11 at 1600 MHz is the standard JEDEC timing for DDR3L-1600; it delivers the rated bandwidth for workstations and NAS workloads.

Can I mix these ECC modules with non-ECC sticks already installed?

Mixing ECC and non-ECC DIMMs is not supported; the system will disable ECC or fail to boot. Use identical modules across all populated slots.
