Why DDR4 RAM is so expensive?

DDR4 RAM is expensive because most manufacturers have shifted production to DDR5, reducing DDR4 supply, while securing limited DDR4 allocations mainly for servers and enterprise systems instead of desktop PCs; combined with ongoing demand, past production cuts, and distributor markups, this keeps prices high.

What is the speed and CAS latency of this DDR4 memory module?

The speed of this DDR4 memory module is 2666 MHz and it has a CAS latency of CL19.

What is the capacity of the Kingston memory module?

The capacity of the Kingston memory module is 32GB.
