Exact-match DDR5 kit

This 64 GB kit contains four 16 GB DDR5-5600 modules built to the PC5-44800 standard. Each stick is a 288-pin unbuffered UDIMM rated at CL46 and 1.10 V with a 1Rx8 organisation. The memory is validated for the ASRock B650M-C motherboard so the controller recognises the full capacity at its rated speed.

Sustained-load behaviour

Major OEM chips from Samsung, Micron or Hynix are tested for stability at the specified frequency, timing and voltage. The fixed 1Rx8 rank structure and standard JEDEC timings allow the memory controller to maintain the rated data rate during extended workloads without downclocking or error correction overhead.

Thermals and power

Modules operate at the nominal 1.10 V without a heat spreader, relying on the board's airflow for cooling. The low voltage and unbuffered design keep power draw modest and acoustic impact negligible in a typical desktop chassis. No active cooling or extra clearance is required.

Questions about this item

Does the 1.1 V, CL46 kit run quietly and cool under continuous load?

The modules operate at 1.1 V with no heat spreader, so they rely on case airflow; power draw at DDR5-5600 is modest and they produce no fan noise themselves.

What motherboard slot and chipset must I already have for this 288-pin DDR5-5600 kit?

You need a board with 288-pin DDR5 UDIMM slots — the kit is validated for the ASRock B650M-C motherboard running DDR5-5600.

Can I mix these 1Rx8 non-ECC UDIMMs with other DDR5 DIMMs on the same board?

Mixing ranks, voltages or timings can prevent the board from training at 5600 MT/s; for guaranteed stability populate all four slots with this matched 64 GB kit.
