32 GB DDR4-2133 kit for desktop builds

This SK hynix kit delivers 32 GB total capacity across four 8 GB unbuffered DIMMs running at DDR4-2133 with CL15 latency at 1.20 V. It suits mainstream desktop systems that need a straightforward memory upgrade without ECC or registered features. The 288-pin form factor fits standard desktop motherboard slots.

Check motherboard DDR4 support and slot count

Verify that the board accepts DDR4 memory and has four available DIMM slots before ordering. Confirm the maximum supported speed and whether the BIOS can run modules at 2133 MT/s with CL15 timings. The kit requires a platform that operates at the standard 1.20 V voltage for DDR4.

Standard voltage keeps thermals and power modest

At 1.20 V the modules draw minimal power and generate little heat during typical workloads. Passive cooling from case airflow is usually sufficient; no active fan on the memory is required. Acoustic impact is negligible because the sticks have no moving parts.

Questions about this item

Does the HMA41GU6AFR8N-TF kit ship as four 8 GB modules or do I need to add more DIMMs to reach 32 GB?

The kit contains four 8 GB DIMMs, giving a total of 32 GB with no extra modules required.

The listing shows DDR4-2133 CL15 — is that the only speed and latency combination available for this MPN?

This MPN is specified at DDR4-2133 with a CAS latency of 15 and 1.20 V operation.

My motherboard has four 288-pin slots; will the PC4-17000 rating run at the advertised 2133 MT/s without manual tuning?

The modules are rated for PC4-17000 at 2133 MT/s and will operate at that speed when the platform supports the JEDEC profile.
