Need some help OC'ing P5Q3 Deluxe / Q9550 / DDR3 1333

post #1 of 6
Thread Starter 
Hello,

Like the title says, i need some help with settings for a stable oc in my p5q3 deluxe. I tried to find some posts on my settings (p5q3, q9550, ddr3 1333), but i was unable to find any.

Can someone help me out with this?

Thanks a bunch.

Compliments.

Just start raising the FSB in steps of 5 or so until it is unstable. When it is, start upping the voltage a little and see if you regain stability.

Don't copy settings, it might not work.

Thanks

How do i see an unstable system? I wanted to push RAM a little bit too, how do i do that?

There are two kinds of instability:

The kind where windows will boot, but crash after a while (could be minutes, could be weeks) because its still unstable.

The kind where its so unstable windows wont start.

Most people up the fsb until it reaches the stage where windows wont boot, then back off about 5 or 10mhz. Then test for stability using a program like Prime95 or Intel burntest and run them for many hours. This is why overclocking is so time consuming. If you have reached a speed you are happy with, then run AT LEAST 8 hours of prime 95 and throw in 20 passes of intel burn test for good measure. If it fails either of these, then back off some more.

Once you have found how fast you can go stability on stock voltage, then it is time to start increasing it and pushing further.

Your ram will be overclocked anyway, as on computers with a FSB like yours, when that is raised, it increases the memory speed. Don't let it get too high, your ram could possibly be a limiting factor in an overclock. You can change the memory speed in the bios too, it gives you a list of speeds to choose from, and the speeds on the list change with fsb too.

So, what's the best way to stress test an overclock?

So far, after messing up with cpu and dram voltage, i got it to work ok, i tested it with Prime95, but i dont know if im using it right.

Config at the moment:

Running @ 4.05Ghz
Cpu Ratio: 8.5
FSB: 475
FSB strap to northbridge: 400
Dram freq.: 1425
FSB : Dram ratio: 3:5
Cpu voltage: 1.38750
Dram voltage: 1.68

Working temperatures:
idle: 25-27 ºC
Load: 63ºC

I think im going to clock down the FSB to 450, and the voltage to 1.31, let's see how this goes.

Comments and help is most appreciated! Bring it on!

Hello there..

I have a similar setup of Q9550 and Asus P5QC (supports both DDR2 and DDR3 memory but it's very similar to your P5Q3)..

Here are my 3.8 - 3.9GHz (450 - 460MHz FSB) stable settings:

Here are settings that need to be applied (leave all other settings at AUTO) :

Ai Overclock Tuner = MANUAL
CPU Ratio = 8.5x
FSB = 450MHz
STRAP= 400
DRAM freq = 1200MHz
DRAM Timings = 8-8-8-24 and the rest on AUTO

Vcore=1.xxV (what your CPU needs for 3.8GHz my is OK with 1.30V,add more voltage if it's unstable)
vPLL= 1.54V
CPU GTL = 0.63x
vFSB = 1.30V
vNB = 1.36V
vRAM = 1.66V
vSB = 1.10V
PCIE/SATA voltage = 1.50V

Load Line Calibration = ENABLED
CPU Spread Spectrum = DISABLED
PCIE Spread Spectrum = DISABLED
CPU Skew = AUTO
NB Skew = AUTO
Performance Mode

Keep your Vcore,vNB and vFSB under 1.40V for 24/7 operation..

Keep your core temperatures under 75C at all time!!


P.S.: That motherboard like many P5Q series mobos (except for P5Q Premium,Deluxe and P5Q-E) is not able to run FSB higher than 460MHz with a C2Quad processor due lack of advanced CPU GTL voltage option in BIOS..

For any other info regarding your setup check out Asus P5Q Pro TURBO/Pro/TURBO owners club here @ OCN (the link is in my sig)..


CHEERS..
