OWC 32GB DDR3L ECC UDIMM kit

This kit provides 32GB of DDR3L memory in four 8GB unbuffered ECC UDIMMs. It is intended for desktop workstations, servers and NAS systems that require error-correcting memory at 1.35V. The modules run at 1333MHz with CL9 latency and conform to JEDEC PC3L-10600 specifications.

Straightforward DIMM installation

Each module uses the standard 240-pin DDR3 form factor and fits into any compatible UDIMM slot. No heat spreader is present, so clearance is minimal. The main risk is mixing ECC unbuffered DIMMs with non-ECC or registered memory, which will prevent the system from posting.

Verify platform compatibility first

Confirm that the motherboard or server board explicitly supports DDR3L 1.35V ECC unbuffered UDIMMs and can address 32GB across four slots. Check the vendor’s qualified vendor list for the exact part number 1E3T32R8032S. Ensure the BIOS is current enough to recognise the 2Rx8 organisation.

Questions about this item

How can I confirm the kit is running at the correct 1333 MT/s speed and CL9 latency after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 1333 MHz with CAS latency set to 9; CPU-Z or a similar utility will also show DDR3L-1333 CL9 on each 8 GB module.

What exactly ships in the box and is anything else required to use the memory?

The package contains four black 240-pin DDR3L UDIMMs, each 8 GB, for a total of 32 GB; no heat spreaders, cables or additional parts are included and nothing else is needed if the motherboard has four compatible slots.

Should I choose this 32 GB quad-channel kit or a different capacity for my workstation?

Select this 32 GB (4 × 8 GB) kit when your board supports four unbuffered ECC DDR3L modules at 1.35 V; choose a smaller kit only if you have fewer slots or a lower maximum capacity limit.
