Kingston Value Series 32GB 5600MHz CL46 DDR5 RAM (KVR56U46BD8-32)

the Kingston KVR56U46BD8-32 is a 32GB DDR5 desktop memory module from the ValueRAM series. While it looks similar to the 16GB model, the "D8" in the part number indicates it is a Dual Rank module, providing higher density.

Key Differences from the 16GB Model

• Rank: This 32GB module is Dual Rank (2Rx8), whereas the 16GB version is Single Rank (1Rx8).

• Component Count: It uses 16 memory chips (8 on each side of the PCB) to achieve the 32GB capacity.

• Compatibility: Because it is Dual Rank,it is slightly more taxing on the CPU's memory controller.If you are using four of these sticks (128GB total),your motherboard may automatically drop the speed below 5600MT/s to maintain stability—this is a standard limitation of the DDR5 platform,not the RAM itself.
