Could this support 128 GB of RAM or more?

Yes, but the Mother Board has six channel memory with 12 DIMM slots. So 8GB x 12 DIMM = 96GB and 16GB x 12 DIMM = 192GB. I'm using a Corsair Vengeance 12 DIMM 192GB Kit for 3200 MHz speed. Be sure to reference supported memory on ASUS website because these large capacity DIMM Sets must be perfectly timed and Matched by Corsair. Enjoy. It's a great board.

Hello, Thank you for contacting us in regards to your question. This board is not an E-ATX. It is considered a 14''x 14'' EEB/ATX Form Factor. Thank you and have a nice day! Newegg Support

Does this support enough RAM to run Chrome?

depends on how much ram you have, if you have less then 1tb of ram then no you cannot run chrome. And that can only run one tab For every tab it is a terribyte of ram.
