Can I use 2 sets of the x2 32GB (x4 32 GB total) to get to 128GB? I built a PC years ago, but I am not a computer expert; I just know enough to be dangerous :)

As long as the CPU and motherboard can support 128gb, yes, you can use two sets of two. Memory specifications for CPU and Motherboard can usually be found in the technical specifications section for the corresponding product on NewEgg. If the information is not listed, it can be found on the manufacturer’s website.

Can I use 2 sets of the x2 32GB (x4 32 GB total) to get to 128GB? Not a computer expert, but I know enough to be dangerous :)

Yes, as long as your motherboard and CPU can recognize that amount of RAM. I have 4, 32 GB sticks of this RAM in my rig and everything checks out (MSI MPG Z690 with i7-12700K).

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.
