NEMIX RAM 32GB DDR4 2666 UDIMM

This module is a 32GB DDR4 2666 PC4-21300 CL19 1.2V 288-pin non-ECC unbuffered UDIMM. It is built for desktop PCs and QNAP NAS units that accept standard desktop memory. The single-stick design fills one slot with the full 32GB capacity. Major OEM Samsung, Micron or Hynix chips are used for reliability.

Suits DDR4 desktops and QNAP NAS needing 32GB per

Ideal for users upgrading a desktop or compatible QNAP NAS where the motherboard supports 32GB density DDR4 2666 UDIMM modules. Systems limited to lower maximum density per slot, or those requiring ECC or registered memory, should look at a different specification. Laptop SO-DIMM platforms cannot use this form factor.

32GB single-module density is the deciding spec

The 32GB capacity on one 288-pin UDIMM decides compatibility. Verify that your board or NAS officially supports 32GB DDR4 2666 non-ECC unbuffered modules before purchase. Speed, voltage and latency are standard DDR4 2666 values, but density is the constraint that determines fit.

Questions about this item

Will this 32 GB DDR4 2666 CL19 module work in my QNAP NAS that specifies RAM-32GDR4S0-UD-2666?

Yes, the supplier title confirms direct compatibility with that QNAP part number.

Does my motherboard need to support non-ECC unbuffered UDIMMs for this stick to function?

The module is a non-ECC unbuffered 288-pin UDIMM, so the board must accept that exact type.

Can I run this memory at its rated 2666 speed without changing any BIOS voltage settings?

It operates at the standard 1.2 V JEDEC voltage, so no manual voltage adjustment is required.
