Any suggestions?
Those are your problems right there.

To leave those settings on auto is to ask for an unstable system.

Every CPU has a sweet spot and you have to set VTT to 1.20 and those two settings to their standart (0.760), then you will have to find on each one the sweet spot like -1 on CPU Ref and +1 on MCH Ref for example. You can only raise vtt from 1.2 after setting those.

Find a template that suits core duo and start from there.

To find out MCH Ref is easy, set it and Memtest #7 and #8.
