Thinking this is my last look (who knows) with DDR2. A few beers on a Monday evening and time to see what these little DDR2 800 sticks can do.
Playing around with the Maximus Formula, Rampage BIOS 0219 (03\05\08)
2.4VDIMM, CAS 5 5 5 15.
It will go further. I now have a corrupt BIOS issue to deal with. Time to get this fixed and back into it
