Kit Composition

This kit contains two 8 GB DDR4 UDIMM modules for a total of 16 GB. It is built for desktop systems that accept 288-pin unbuffered memory running at 1.20 V. The green circuit boards carry no LEDs.

What the Pair Changes

Populating two slots in matched capacity lets the memory controller run in dual-channel mode, doubling the data path compared with a single module. The CL15 timing at 2133 MHz is the only speed grade supplied; no XMP profiles or higher frequencies are included.

DDR4 Bus Limits

The DDR4 interface tops out at the PC4-17000 data rate, so bandwidth cannot exceed what the 2133 MT/s clock provides. Systems that require ECC, registered modules or voltages other than 1.20 V will not work with this kit.

Questions about this item

Will these two 8 GB modules work together as a 16 GB kit in my desktop?

Yes, the pack contains two matched 8 GB DDR4 UDIMMs designed to run together at 2133 MHz with CL15 timing.

My motherboard has 288-pin DDR4 slots — is the physical fit guaranteed?

Each stick is a standard 288-pin unbuffered DDR4 DIMM, so it will seat in any desktop DDR4 slot.

Do I need to change any BIOS voltage settings for these sticks?

The modules operate at the standard 1.20 V, so no manual voltage adjustment is required.
