PCPartPicker list shows item details for memory products. G.Skill Ripjaws V 32 GB (2 x 16 GB) DDR4-3600 CL16 memory is priced at $129.99 on Newegg, with shipping and taxes included. Total reflects current offers. This configuration fits well with Ryzen processors, though specs may vary for other chipsets like R5000.
Short version, there is no practical performance difference between them. The loading on the IMC will be the same assuming they're modern modules. If you go 2x16 you'll leave the door open to adding more ram in future should it be needed.
Various factors play a role based on the modules used. If the 8 GB DIMMs are single rank and the 16 GB DIMMs are dual rank, their electrical behavior is nearly identical. They will perform exactly as the product specifications state. Adding two 16 GB modules offers a more affordable option for future upgrades.
Both kits should work similarly because Ryzen CPUs only support two memory channels, so adding four sticks won’t boost bandwidth much (unless you upgrade later). With two 16GB sticks, you’ll still have flexibility for future upgrades. A 3200 CL16/14 or a 3600 CL16 should suffice, though a 3600 CL18 offers comparable latency to a 3200 CL16. Regarding currency, it seems you’re referring to USD.
Checking for single or dual rank is straightforward with these parts. Here are the modules you mentioned: 1. Corsair Vengeance LPX Black DDR4 3600MHz 2x16GB (CMK32GX4M2Z3600C18) 2. Corsair Vengeance LPX Black DDR4 3600MHz 2x8GB (CMK16GX4M2Z3600C18) Remember, being in Sweden limits the usefulness of online links, but the part numbers should help.
Recently available 8GB modules are all single-rank configurations. Dual-rank options existed only in the early DDR4 era. All 16GB modules are dual-rank as well. The key factor isn't the module count but how the rank is loaded. As mentioned before, loading behavior remains similar according to IMC observations.
