Hey everyone, longgggg time lurker here, I never post! Just wanted to start by saying thanks to Jor3lBR and nugzo, your BIOS settings have helped me alot.

The Q9650 and UD3P truly were made for each other. I'm at 4.25GHz stable, but I'm pretty sure I could run this baby at 4.4 or 4.5 24/7 stable if I had better watercooling. I just have a crappy rad (MCR220). I should've gotten the Thermochill or Faser '3 fan' rad Oh well.

No success running 509+ FSB at a lower multi Best I got at a lower multi was 508x8.5, but I think I like 473x9 better. Let's me run my Dominator's at SIGNIFICANTLY better timings.

I'm Prime95, OCCT, and Orthos Stable...but I fail IBT instantly, IBT gets my CPU wayyyy too hot (75C+). I doubt anything I'll ever run will get my CPU that hot so I'm ok with failing that.

Also, thanks to EVERYONE in this thread because it wasn't just nugzo and Jor3lBR that helped me, it was comments posted by many different people in this thread and in nugzo's other UD3 thread.

Good luck to everyone and I hope you can acheive a good stable clock like I have, it's a good feeling!
