Hi everyone, I have an issue since some years that I have never succeeded to understand on what it depends I have a computer assembled by me with these features:
Processor: Intel i73770
Motherboard: asus P8z77-v deluxe
Ram: 32 GB, corsair CMz32GX3M4X1866C10
GPU: Gainward geforce 680
When I have assembled this pc for some months both windows and ubuntu they was reading 32 GB of ram fully. After some months suddenly it reads 16 GB of ram, from bios also if the rams are 1866 mhz I can take them only maximum to 1600 mhz. I can't understand why I have this issue and how to solve it. I attach to this conversation some screen of cpuz and windows properties.
Thank you for helping

1| Have you made sure your BIOS is up to date?
2| Your ram is running at 1333MHz as opposed to your kit being rated to run at 1866MHz.
3| You seem to be on Windows 10, did you experience this issue with Microsoft's Windows 7 or 8/8.1?
4| Remove your CMOS battery for at least 15 minutes before replacing it and reseat your ram sticks before powering up your system.
5| You may also want to run only two sticks of ram at a time to see if the slots on your motherboard are the culprit or if the rams failed on you.
