BiOS & CPU-Z recognize 16 GB of RAM but Windows only sees 8 GB

Windows 10 Home 64-bit i7-7700k, not overclocked

Windows recognized all 4 slots before upgrading the CPU (6700k to 7700k). Everything worked. After the new install, BiOS and CPU-Z both recognize 16 GB of RAM. Windows only sees 8 GB now.

Slots are still being recognized. Swapped spots and each stick was picked up.

Windows recognize both sets independently, & in different slots.

Made sure that there was no RAM cap (Unchecked, at 0 in MSCONFIG).

BiOS is up to date.

Loosening CPU did not help.
