What's up all. I have a RE3 Extreme with 12gb of memory but the bios is only seeing 8gb. CPU-Z also detects 12gb.
Thoughts or ideas?
Try 1.66v in bios for your ram and 1.35v for your QPI/VTT. Try running a lower frequency or looser timings on your ram with 12gb's.
If above doesn't work, check to see if your heatsink is on too tight. Check mobo socket for any bent pins. Make sure your board isn't bending or being warped by your heatsink.
