A:Answer The RAM installed is 2×8GB modules of DDR5-5600. The brand of RAM is Samsung, and the RAM model number is M425R1GB4PB0-CWMOL.
There is only 1×M.2 2280 Gen 4 SSD slot running on x4 channels. The installed brand of SSD installed is Sandisk, which is a 512GB module with the model number SDEPNSJ-5126-1006. Some people have mentioned that their machine has a Samsung M.2 card.
If Upgrading:
Be sure to note that the RAM modules supported are 2×8GB DDR5-5600, 2×16GB DDR5-5600, and 2×32GB DDR5-4800. If you upgrade to the max capacity, you will not be able to use the Overclocked RAM speeds, and the motherboard officially supports DDR5-4800 up to 64GB total or DDR5-5600 [Overclocked] up to 32GB total.
Be sure to note that the maximum supported SSD drive capacity is 4TB, and it must be Gen 4 or earlier, this will support a Gen 5 module, but it will perform at Gen 4 speeds. Do not use a SSD with a heatsink, as it will not fit properly, and will not be cooled properly.
I hope you find this information useful. I do not work for Best Buy and am not associated with them at all. It took trial and error along with research to find the information pertaining to the RAM speeds supported by the motherboard.
