32GB DDR3L ECC Kit for Workstations

This kit supplies 32 GB of DDR3L memory across eight 4 GB unbuffered UDIMMs. Each module runs at 1866 MT/s with CL13 latency at 1.35 V and includes ECC error correction. The set is built for desktop workstations, servers and NAS systems that require registered-style reliability without registered buffering.

Dual-Channel 240-Pin Upgrade for Compatible

The modules use the standard 240-pin DDR3L form factor and are organised as a dual-channel kit. They fit motherboards that accept unbuffered ECC UDIMMs at the 1.35 V JEDEC voltage. No heat spreaders are fitted, so clearance inside tight chassis or beside large CPU coolers is maximised.

Replaces Lower-Capacity or Non-ECC DDR3L Sets

Moving from a smaller non-ECC kit to this 32 GB ECC configuration adds both capacity and single-bit error correction for data-critical workloads. The jump is worth it when the platform supports unbuffered ECC and the application benefits from the extra headroom and integrity checking.

Questions about this item

Will this kit work in a system that requires DDR3L 1866 with CL13 timing?

Yes, the kit is specified as DDR3L 1866 PC3L-14900 with CAS latency 13, matching those exact requirements.

Can I use these modules in a motherboard that only has four DIMM slots?

The kit contains eight 4 GB modules, so a board with only four slots cannot accommodate the full 32 GB at once.

Is the memory compatible with a workstation that needs ECC unbuffered DIMMs?

The modules are ECC unbuffered UDIMMs, which is the standard type used in many workstations and servers.
