The LGA 1155 is maxes-out at 32GB with pricey 4x8GB kits; though the prices for 4x8GB have come down to ~$300. However, if you want and really need >32GB then you have (2) choices: 1. SB-E/LGA 2011 X79 64GB or 2. older i7-9XX (Xeon)/LGA 1366 X58 48GB; Xeon 256GB.
Q - What's the purpose of the build?
With all that RAM my assumption is Rendering, RAM Drive, Larger data, 'Server', etc... In some instances e.g. Server, Data, and in many cases Rendering you might want a Xeon based system.
