OC Q9550 on Asus P5Q-E

[hymerschmidt]

Hello,
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.

What exactly is keeping you from going higher? Stability tests failing or auto-restarting? Provide more details please.

Only the ones who have Q9550+P5Q-E, know how to OC AND willing to guide you through step to step. Hence, there is 99.999999% of the chance that you won't get any help of the kind.

Probability(step-to-step help) = Probability(have Q9550+P5Q-E) * Probability(know how to OC) * Probability(willing to give step-to-step help)

Probability(have Q9550+P5Q-E) = 10% = 0.1, expect much less!
Probability(know how to OC) = 50% = 0.5, expect much less!
Probability(willing to give step-to-step help) = 1% = 0.01, expect much less!

=>Probability(step-to-step help) = 0.1*0.5*0.01 = 0.0005 = 0.05%

Those are some bad odds LOL

try google dude , those odds really suck lol.


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.

Adjust fsb to 400 mhz, there you go all set.

Come on guys, give him a break.

hymer, there's a lot of guides out there. There's general guides and guides specific to certain motherboard/CPU combinations.

This should be your first stop. (General guide)
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1
http://www.tomshardware.com/forum/240001-29-howto-overclock-quads-duals-guide

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.

The ACF7P is, by today's standards, a barely average cooler. Here are three under
$50 heatsinks that are pretty popular:
COOLER MASTER Hyper 212 Plus

Sunbeam

Xigmatec Dark Knight

They all require a somewhat different approach to applying thermal compound.
Suggestions for applying thermal compound:

And they are pretty large, so they might not fit inside your case.

Watch your voltage and temperatures. Intel's recommended maximum voltage for a Q9550 is 1.3625 volts. Max temperature is 74.1 C. I recommend keeping the load temps under 70 C.

Remember, these are guides, not cookbooks. YMMV.
