Workstation MB ?

[littlewit]

I need lots or Ram (Need to setup a Ramdisk to do stat analysis in real-time) . Looks like X99 based MB max out at 128GB, what are my other options. I looked at Server MB but they don't have other items I want like M.2 or multiple PCI-3 slots ?

Also any recommendation on a Ramdisk software for Windows 10 ?

Thanks
