Capacity and fit

This 32 GB DDR5 DIMM runs at 5200 MHz with CAS latency 42 and 1.10 V. It is an unbuffered non‑ECC module built with major‑brand DRAM ICs and carries the PC5‑41600 designation.

Connector and daily handling

The module uses the standard 288‑pin DDR5 DIMM edge connector and has no heat spreader. Its green and black PCB fits directly into any desktop DDR5 slot and the low 1.10 V operating voltage keeps power draw minimal during everyday workloads.

Pre‑order checklist

Verify that your motherboard supports DDR5 memory at 5200 MHz and accepts unbuffered non‑ECC DIMMs. Check the manual for the correct slot population order and confirm the board can run at the module’s 1.10 V default voltage.

Questions about this item

Does the DDR5 5200 PC5-41600 module run at its rated speed on a standard 1.10V platform?

Yes, the module is tested at 5200 MT/s and operates at the DDR5 standard voltage of 1.10V, so it will run at its rated frequency on any compatible desktop platform without manual voltage changes.

Will the 288-pin DIMM fit in a standard desktop motherboard slot without a heat spreader?

The module uses the standard 288-pin DDR5 DIMM form factor and has no heat spreader, so it fits any desktop DDR5 slot and clears most CPU coolers that might overhang the memory banks.

What is the correct way to seat this unbuffered 2Rx8 module, and what step do builders often miss?

Align the notch with the slot key, press down firmly until both retention clips click shut, then verify the module is fully seated by checking that no gold contacts are visible; the step often missed is applying even pressure on both ends simultaneously so the clips engage together.
