I have the same CPU running at 3.33 with bus speed 476, rated FSB at 1908, core voltage at 1.41250. I had to unlink the memory as it wouldn’t take the speed. Suggest you get the CPU cranked up and stable before you try to work the memory.
This motherboard only lets me raise vtt by .5 So 1.35, 1.40, 1.45. At 1.40 and FSB of about 1900 it locks up while trying to load windows. 1 out of 20/30 tries will get me to windows but will freeze up seconds later.
I think you need to determine if it’s a CPU or memory limitation that’s stopping your progress. I would crank up a memory divider trying to keep memory at stock speeds. If you’re BIOS allows you do unlink the memory from the CPU even better. Maybe one of the OC pros will have some ideas for you.
I can't imagine it being memory. Is it possible that it's my motherboard? Strange thing I noticed the other day.. if I run that AI Boost from Asus, it has a bar which shows your current speed.. 2.33 would be green, 2.88 is almost red and 3.2 would be red all the way. Anyone else with Asus.. is that a common thing where it would seem as 3.2 would be max in that program ?
