I was wondering if anyone could give me a step by step answer on how to overclock my Intel Q9550 from 2.83ghz to 3.4ghz. I have an Asus P5Q-E MB, 4gb ddr2 1066 g-skill ram, and a 750 watt psu. I just put the Freezer 7 Pro heatsink on it and it runs around 55degrees underload at most thnx.
I have a similar system OC'd to 3.2 Ghz without a raise in temps under load or idle.
Find a Core 2 Quad guide to OC'ing for newbs their out there.That combination will do it no problem .Try OCCT for testing OC ,dont use PC probe use core temps ,or real temps . Don't overvolt or overheat .When you think your ready to OC don't ,Study your bios and your hardware well ,be sure of your settings "notes help " concentrate extreme focus on task and then you will be ready grasshopper to OC . toasting to Jobu might help too.

Next stop should be a guide for your particular motherboard. Google is your friend.
Go through the guides. Then go into the BIOS and change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in step with it. If you are at stock speed (333 MHz X 8.5), your memory clock should be at 667 MHz.
Download CPU-Z to check your FSB:RAM ratio.
Warning - confusion factor between what the BIOS calls things and what CPUZ calls things. What the BIOS calls "memory frequency" is actually the memory clock. What CPUZ calls "memory frequency" is half the memory clock - DDR2 RAM, remember? It transfers two chunks of data each bus cycle. What you want in CPUZ is a 1:1 FSB:RAM ratio.
Overclocking memory doesn't accomplish much besides limiting your CPU overclock where the real speed comes from.
