Hey Thugs, I've gotten lots of good information from this thread. I think you've got an amazing overclock. You've done all the testing for us and found whats stable whats not, whats fast and whats slow.
I too have the Asus 845d but I think I made a mistake getting the 1.8 over the 1.6 I dunno why the 1.8 would react so much differently to overclocking, but it just doesn't seem to take it well.
I was get an annoying little random beep when I got up to 133mhz fsb (2.4ghz) I'm guessing its my power. The 1.8 wouldn't boot windows without atleast 1.7 Vcore, and even then it wasn't perfectly stable. Hopefully the Enermax 550 will get rid of that beep and maybe pull a little more out of this 1.8. My goal was 150 but after seeing this 1.6 at 170+ air cooled, maybe I should ditch this stubborn 1.8 and look for a lucky 1.6. My heats not too bad at 2.4 it was running at 30C idle and 37C under load (pretty hot day). If this 1.8 continues to be this way after the PSU upgrade and the 1.7V wire mod. Then its time to buy a 1.6.
Goodluck to you all with your overclocking, let us know your secrets
