It is a single-rank model.
You're seeing two kits available (4x8GB). It's recommended to use 2 units of dual-ranked RAM or 4 units of single-ranked RAM in your system. Are you looking for the specific DRAM type or SRAM type? You might want to consider a 2x16GB kit if needed.
CPU-Z will tell you for sure but I'm 100% sure they'll be single rank. Dual rank 8GB modules haven't existed for a very long time (last one I got was in 2015). Even 16GB modules have moved towards single rank for some time. OP is running 4x8GB so that is as good as it gets already.
Are you confirming the 4x8GB setup? Using 2x8GB might slightly reduce performance, though it shouldn’t be an issue if storage isn’t an obstacle.
If the kits function properly, you can smoothly run XMP/DOCP without issues, and there have been no problems encountered so far, irrespective of the configuration level. However, most 8GB kits are typically single-rank; I believe there were some early DDR4 8GB dual-rank options, and certain ECC server-grade models can also support dual-rank at 8GB. Unless this RAM is from a different era, you should have four single-rank modules.
