32GB DDR4 2666 ECC VLP DIMM

This single 32GB DDR4 2666 CL19 ECC unbuffered VLP DIMM operates at 1.2V using a 2Rx8 layout on a 288-pin module. It is built for select workstations, servers and NAS systems that require error-correcting memory in a very low profile form factor.

Check DDR4 2666 ECC unbuffered support

Verify that your motherboard accepts DDR4 2666 ECC unbuffered DIMMs and has a free 288-pin slot. Confirm the platform works with 1.2V modules and can run at CL19 timings. OWC recommends matching capacity, speed and manufacturer across all installed DIMMs for optimal performance.

Thermals noise and power draw

The module runs at the standard 1.2V without a heat spreader, relying on case airflow for cooling. No LEDs or active cooling are present, so the DIMM adds no audible noise. Power draw stays within JEDEC limits for DDR4 2666 operation under normal workloads.

Questions about this item

Will this 32 GB DDR4 2666 CL19 ECC unbuffered VLP DIMM fit my workstation that requires 288-pin modules?

Yes, the module uses the standard 288-pin DDR4 form factor and runs at 1.2 V, so it will physically install in any desktop or workstation slot that accepts DDR4 2666 ECC unbuffered memory.

Can I mix this stick with existing non-ECC RAM in my server?

Mixing ECC and non-ECC modules is not recommended; the system will typically disable ECC or refuse to boot, so populate all slots with identical ECC unbuffered DIMMs for reliable operation.

Does the very-low-profile height clear large CPU coolers in a 1U NAS chassis?

The VLP (very low profile) design is shorter than standard DIMMs, making it compatible with tight clearance environments such as 1U rackmount NAS or server enclosures.
