Capacity and compatibility

This is a single 32GB DDR5 desktop memory module rated at 5600MHz with CAS latency 40 and a standard 1.1V operating voltage. It is built as an unbuffered non-ECC DIMM using major-brand DRAM ICs and is validated as a direct replacement for Kingston part KCP556UD8-32.

Installation notes

The module uses the standard 288-pin DDR5 DIMM form factor and installs like any desktop memory stick by aligning the key notch and pressing firmly until the retention clips engage. Common issues arise when the motherboard BIOS has not been updated for 5600MHz operation or when the system requires a different rank configuration or ECC support.

Who this suits

Ideal for users upgrading a desktop that specifically calls for a 32GB 2Rx8 DDR5-5600 non-ECC module and wants a tested Kingston-compatible alternative. Not suitable for laptops, servers needing registered or ECC memory, or platforms limited to lower DDR5 speeds or different pin layouts.

Questions about this item

Will this 32GB DDR5 5600MHz module fit my desktop motherboard?

The module uses the standard 288-pin DIMM form factor for DDR5. Check your motherboard manual to confirm it supports DDR5 memory and the 5600MHz speed at 1.1V.

Is this RAM compatible with the Kingston KCP556UD8-32 I want to replace?

Yes, this A-Tech module is specified as a compatible replacement for the Kingston KCP556UD8-32, matching the 32GB capacity, DDR5 5600MHz speed, 2Rx8 rank, CL40 latency and 1.1V voltage.

Do I need to change any BIOS settings to run this memory at 5600MHz?

Most modern DDR5 motherboards will automatically configure the correct 5600MHz frequency and CL40 timings at 1.1V. If the system boots at a lower speed, enable the XMP or EXPO profile in BIOS to reach the rated 5600MHz.
