Will this work in my desktop?

It fits boards with DDR5 DIMM slots and standard desktop CPUs. Check your motherboard's qualified memory list and maximum capacity before buying.

Is CL46 a problem for gaming?

It costs some frame rate versus low-latency kits, but at 5600MHz the gap is modest. Most games are limited by the GPU, not by this latency.

Yes, if your board has four slots and supports 128GB. Matching the same kit keeps speeds and timings consistent.

No. It runs at DDR5-5600 through the standard JEDEC profile, so it should reach full speed without BIOS tuning.

It works on both. AMD's sweet spot is often 6000MHz, so expect slightly lower bandwidth than a 6000 kit on AM5.

Two 32GB DDR5 DIMMs. No heatsinks or extra accessories are included.
