I hear ya. I have pretty much combed the net for tweaks and ideas and used them to death. What I have found is what works for one doesn't always for the other. I will tell you from the contest I improved my Superpi by 20 seconds at the bot which netted me a 7 min 2 sec run. ALMOST SUB-7!!!!
You are one of the greats at this bench and it was a privilege to go neck to neck with ya if you want to call it that. I was just interested in what tweaks you might have used to see if I have tried them as most of the info out there are for 775's which are a different story. What I found that works best for me is of course a fast overclock on my CPU, high MHz on my RAM with tight timings with of course tight sub-timings. I have many of more runs on this bench and I mean many of more before I consider myself good at it. This bench was once one of my not-liked benches but has become my favorite since I've had my i7 platform.
