openCore 0.6.8 on macPro6,1 with 128Gb RAM —> 96Gb available RAM

so ive been running OpenCore 0.6.8 with macOS 13.2 which showed my full 128Gb of physical RAM — tonight i upgraded to macOS 13.5 and applied the OpenCore 0.6.8 post-install root patch, and i got my dual monitors back, and graphics acceleration, and the process went remarkably smoothly — a testament to how well made OpenCore is — however, it no longer shows my full 128Gb of physical RAM 😳 it shows 96Gb installed, and System Report indicates that 'Your Mac contains 4 memory slots — 3 memory slots in use, 1 available [slot 2].

it is possible that a memory DIMM became dislodged or defective due to heat? however i did not physically move or disturb my machine, and this showed up right at reboot. im about to boot off an older installer (Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave) just to see if it reports the full 128Gb RAM.
