I'm running 3 sticks on digitus 10 port https://www.digitus.info/en/products/computer-accessories-and-components/computer-accessories/usb-hubs/da-70229/   ... running fine at 832 MHz ( 4.7 MHs, HW around 1%)

Hub has room to accomodate 6 sticks but you would need to underclock them as the power supply is only 5V 4A.
