Q9450 Overclocking Tips and OC Results

Sure, in this case pure Ghz sounds plausible but I am targeting specifically gamers who blindly wants bragging right. There are cases that the game actually runs slower by having FASTER Ghz by "studdering" due to unsync mem to fsb, GPU bottlenecking, and other areas of the peripherals bottlenecking. I called it "choking" and redoing tasks -- overall making everything just slower.

What you describe does happen if the CPU is too fast, but not with single video cards, only SLI'd or Crossfired cards. It happens because of the way multiple video cards display their images, called AFR, or Alternate Frame Rendering. Later on in this thread, it's explained why it happens. Just so you know, though, quite a few people don't notice microstuttering (what you're describing), unless it's extremely bad, while other people say they notice it much, much sooner.

edit: I forgot something here. AFR (SLI or Crossfire) always has some microstutter, but having a CPU that's too fast for your video cards just makes the problem worse.

Not everyone uses their computer for games.

True, but then you're missing the point of the characterization...

My Q9450 tops out at 3.56GHz @ 1.275v, I can't get 3.6GHz stable with 1.35v, and anything beyond 1.3v makes my temps start to skyrocket. Most Q9450 overclocks I've seen were not stable beyond about 445MHz fsb, or they required crazy amounts of voltage.

Xpose, if you have a setting in your BIOS called "Load Line Calibration", set it to Enabled (vdroop control). Then lower your vcore more, you should be able to get 3.5GHz stable on 1.3v or less.

I got a 3.592GHz overclock with about 1.3v (I enabled some "Performance Boost" stuffz in my BIOS, but I can run it at lower voltage) with FSB 449. For some reason it can do 3.592GHz but 3.6GHz is impossible
