XMP Not Working After Upgrading From 16GB to 32GB
So I recently upgraded my rig from 16GB DDR4 (2x8GB) to 32GB DDR4 (4x8GB).
I am using Corsair Dominator Platinum DDR4 ram which OC's to 3000 Mhz. My motherboard is the ASUS Prime Z720-A.
When I had the original setup of 16GB, just two sticks of 8GB each, I could use XMP on my motherboard and everything went perfectly. However, after adding two more sticks of 8GB (4x8GB), now XMP is causing post failures and my motherboard is having to start in safe mode. If I turn XMP off, everything runs fine, but my ram is only running at 2133MHz.
Any thoughts on what could be the issue?
