  • 32 GB capacity from four 8 GB modules
  • ECC protection detects and corrects memory errors
  • DDR4 2666 CL19 speed with 1.2 V operation

OWC 32 GB DDR4 ECC kit

This OWC kit provides 32 GB of DDR4 ECC memory in four 8 GB UDIMM modules. It runs at 2666 MHz with CL19 latency and operates at the standard 1.2 V. The modules are unbuffered, single-rank 1Rx8 parts with 288-pin connectors. They are validated for Dell PowerEdge R240, T140 and T40 systems.

Suited for ECC-capable servers

The kit targets administrators upgrading PowerEdge R240, T140 or T40 platforms that require ECC UDIMM memory. It also works in other desktops, workstations or NAS units that accept DDR4 2666 ECC unbuffered DIMMs. Builders needing registered DIMMs, higher frequencies, larger capacities per module or non-ECC memory should look at different products.

2666 MHz DDR4 ECC speed

The decisive specification is the 2666 MHz DDR4 ECC unbuffered rating. Your system must support DDR4 ECC UDIMMs at this speed; the modules will down-clock to 2400 MHz or 2133 MHz if the platform requires it, but they will not function in boards that only accept registered memory or non-ECC memory.

Perguntas sobre este artigo

Will the CL19 latency limit throughput on a Dell PowerEdge R240 running 24/7?

The modules run at DDR4 2666 with CL19 timing; latency is fixed by the JEDEC specification and does not change under sustained load.

How much heat and power do the 1.2 V unbuffered ECC DIMMs produce during all-day operation?

Each 8 GB stick operates at 1.2 V without a heat spreader; total kit power stays within standard DDR4 limits for unbuffered ECC UDIMMs.

Must the server already have four free 288-pin DDR4 slots to install this 4 x 8 GB kit?

Yes, the upgrade requires four available 288-pin DDR4 UDIMM slots; the kit is validated for PowerEdge R240, T140 and T40 platforms.
