Question 16gb ram modules registered in BIOS as 8gb ?

[Winther1]

I have an Intel NUC8I7BEH3 and recently wanted to upgrade it from 16 to 32gb ram.
I was running the Corsair Vengeance modules and went for the same brand

Somehow Geekbench 5 can see the 32gb DDR4 ram:

But not the System Information or BIOS (which I have upgraded to the latest version). Any idea what I can do?

Did you clear CMOS after the bios update? That should fix it if you haven't done it yet.

On the NUC the battery is located on the underside of the motherboard so I have to remove it from the chassis. Can it be cleared without taking out the battery?

Can it be cleared without taking out the battery?

Can you show screenshots from CPU-Z - memory and spd sections,
Task Manager - Performance/memory section?

Thanks for the replies.
Just like Geekbench, CPU-Z sees the 32gb memory just fine, so I guess we can exclude any module or slot/installation faults:

Slot 1 and 2 exactly the same

However, task manager only sees 16gb. The main reason I upgraded was for Premier Pro and Photoshop - I wonder if they are using the added ram or only sees 16. I'm really confused!

Try booting with single 16GB module installed.
Try it in both slots.

Check msconfig/boot/advanced. Maximum memory checkbox should be unchecked.

Thank you for the last tip! I took out one of the modules and booted up the NUC. Took longer to start up so something was going on. As I entered the bios, it registered one module as 16gb so progress!
I put in the second module and 32gb registered

I can only think that taking out one module reset someting in the bios - in any case, thanks for the help!!!!
