I've been working the HTT up in 5mhz intervals with the ram at stock timings of 3 4 4 8 @ 2.8V and finding the exact vcore I need for a stable system at each setting. I got to 225x12 (2.7ghz) with the vcore at 1.7V and the system stable but when I tried 230x12 it wouldn't even pass OCCT. So I dropped the multi to 11 and worked up to 235x11 (2.59ghz) with no problem but when I tried 240x11 (2.64ghz) even at a vcore of 1.7V the compter wont boot into windows. Once again I dropped the multi to 10 (2.4ghz) - can't get into windows. Then 9 (2.16ghz) - can't get into windows. Then set the ram on the 2/3 divider - still no luck. I'm stumped but think either the CPU is just not up to it or I need a better PSU. I currently have an X-Pro 460W. Any ideas?
