Why DDR5 RAM is so expensive now?

DDR5 Memory is pricey due to the surging demand from AI server farms and data centers, which has caused a global memory shortage. This has led memory manufacturers to prioritize more profitable server-grade memory like HBM (high-Bandwidth Memory) over consumer-grade DDR5, drastically reducing supply for consumers while simultaneously causing the prices for both DDR5 and DDR4 to increase.

What is the CAS latency and voltage of this DDR5 RAM?

The CAS latency of this DDR5 RAM is CL42, and it operates at a voltage of 1.35V.

What is the capacity and configuration of the CORSAIR Vengeance RGB memory?
