A:Answer If your looking to run higher than 3000mhz this PC isn’t for you. The motherboard on this rig is a Asus Tuff B365M-Plus and will run 4x16 RAM sticks, however because it’s only a dual channel(four RAM slots) it is recommended you go with 2x32 sticks of RAM. Also, this motherboard only supports 2666mhz sticks.
If your looking to do some minor gaming without streaming NOT in 4K, this rig will work fine. Also, 64 RAM sticks is overkill for a entry level rig like this.
Spend that money on a more complete rig.
