Strange issue with new build

[jasonf12014]

Hi

I've just build a new PC using an MSI B450 tomahawk, Ryzen 2600 cpu and 16gb Team Group Vulcan t-force memory. System boots but bios only reports 8gb, windows says 16gb 7.95gb usable. The memory is in slots a2 and b2 which is the recommeded ones. Just as a test I tried the memory in a1 and a2, bios saw 16gb but complained it wasn't optimal configuration. I've updated to latest bios, 7C02v13 same issue.

Any help would be appreciated

What about B1 & B2?

It's possible one of the B slots are faulty?

Good call try b1 b2 to rule out a faulty slot.

Don't mean to sound insulting but you did check it was pushed all the way in?

Also try one stick of RAM at a time in all slots.
