GTX 970 unstable with 32GB RAM, BIOS Problem?

Everything was fine until I upgraded my RAM to 32GB from 16GB, initially I thought it was a faulty RAM but after performing a test with Windows Memory Diagnostic Tool and Memtest86, both software came back with no faulty RAM report.

After searching the internet for answers, I found this forum - forums.geforce.com/.../

Test I've conducted:

• 32GB (4x8GB Kingston dual channel) RAM runs with no problem or error for hours when I swapped my GTX970 for a GTX745.
• 16GB (2x8GB Kingston dual channel) runs with no problem on GTX970, I swapped the RAM twice to make sure it is not because of a faulty RAM.
• 16GB (2x8GB Kingston and 4x4GB Samsung dual channel) runs with no problem on GTX745
• Windows Freezes and hanged after 10+ minutes when I have 32GB (4x8Gb Kingston) and GTX970 running.
• Not overheating because I have a table fan blowing at my CPU
• Not RAM slot issue because my old 4GB RAM works fine

I've concluded that my Asus GTX970 is not compatible with 32GB RAM, my windows will freeze and restart, I believe this is a driver issue. I hope Nvidia can look into it. Maybe an Asus card thing?
