Unable to use RAM slots C1 et C2 on TRX40 Creator

[dwardanderson]

After upgrading my BIOS to 1.70 half my memory does not show on the Bios screen. Corsair Vengeance DDR4-3200 installed in D2, C2, A2 & B2 under Bios 1.5 now show only in D2 & B2 in Bios 1.7.
Reseated the Memory, cleared the CMOS, reset the Motherboard. No change/improvement.

Why did you upgrade the bios? Can you downgrade and does everything work as before when you do?
