  • 2V operation reduces power draw and heat

Module details

This SK hynix desktop module delivers 8 GB of DDR4 memory at a tested 3 200 MT/s rate. The stick uses an unbuffered 288-pin DIMM layout and runs at the standard 1.2 V. A CL22 latency figure is reported for the tested frequency. The green PCB carries a single-rank 1Rx16 chip arrangement.

Who it fits

System builders upgrading or repairing a DDR4 platform that accepts 3 200 MT/s unbuffered DIMMs will find this module compatible. Users requiring ECC error correction, registered buffering, a heat spreader or RGB lighting should select a different part. Laptop or small-form-factor boards needing SO-DIMM modules cannot use this full-size stick.

Deciding spec

The single-rank 1Rx16 organisation is the critical specification that determines whether the memory controller can address the full 8 GB capacity on this module. Some consumer chipsets limit the number of ranks per channel, so verifying 1Rx16 support avoids a no-post or reduced-capacity outcome.

Questions about this item

What motherboard slot and voltage must my system provide for this DDR4 3200 DIMM to work?

The module needs a standard 288-pin DDR4 DIMM slot and runs at 1.2 V.

If I keep my older DDR4 memory installed, will this module still operate at its rated speed?

The system will run all modules at the slowest common speed; this stick is rated for 3200 MHz CL22, so it will match whatever lower speed the older kit requires.

How can I confirm the module is running at its specified 3200 MHz and CL22 timing after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; they will report the current frequency as 3200 MT/s and the CAS latency as 22.
