I have built my new gaming PC a few months back. I struggled a bit with trouble shooting blue screens. I finally resolved them by removing 2 of the 4 gigs of ram I have and I loosened up the timings a bit. It has been stable for a couple months. I tried tinkering a bit with suttle overclocking, I even tried Gigabytes over clocking software. I did not get very far without lock ups or booting problems. I have spent countless hours reading thru forums about overclocking, and I can tell you my head hurts. I am wondering if I can get a fresh simple start here? I am not looking to get crazy, I just want to get a better bang for my buck. I know I have the hardware, I just don’t seem to grasp all these voltage settings and which ones to really start with? The only benchmarking utility I have is 3Dmark06. That at least gives me some idea if I am heading in the right direction. Like I mentioned, I am currently only using (2) 1 gig sticks of ram. I do have 2 more of the same, but I don’t really think I need them, at least at the moment. Can anyone help me out as to where to start? I don’t need to do this over night, but perhaps you can look at my current specs and bios settings and suggest some simple changes I should start with first? I do have CPU-Z and Core Temp utilities installed for monitoring. Thanks in advanced,

I use the DS4 version, not DQ6, but the options look identical.

For 3.2ghz overclocking:
In the MB Intelligent Tweaker screen, set:
Robus graphics booster: standard
CPU clock ratio: 8x
cpu host clock control: enable
cpu host clock frequency: 400
PCI Express frequency: 100
C.I.A.2: disable
Performance Enhance: standard
System memory multiplier: [2.00D]
Dram Timing Selectable: Manual
Standard Timing control:
6
6
6
18
System voltage control: manual
DDR2
Overvoltage: +0.2 to +0.4 (depends on your memory's rated voltage.
Overvoltage starts with 1.8volts base. If ram is rated to run at
2.0volts, it's 1.8+0.2=2.0volts. If ram is rated to run at 2.2 volts,
it's 1.8+0.4=2.2volts.) Running at higher voltage increases stability,
but also increase heat. Running at voltage higher that memory's rated
voltage can damage it.
Loadline Calibration: Enable
CPU Voltage
Control: 1.4 to 1.5, higher voltage increases stability, but produce
more heat. Try 1.4 first, if unstable, try 1.45, if still unstable, try
1.5. Do not go over 1.5.

Leave everything else at default.

If
your system is stress tested stable, you can choose to tightening ram
timing(Standard Timing Control) for a small performance increase.
6/6/6/18 is high, the lower those numbers, the faster it runs.

Those settings are for 3.2ghz on Q6600. If your system stress tested stable, set CPU Clock Ratio to 9x for 3.6ghz.

That's about it. Assuming the 2 boards are the same, of course. Good luck. :p

Your appreciated response suggest a jump from stock settings right to 3.2. That will be great if it works fine right off the bat. I guess I will implement these changes and see what happens. If it doesnt work, I will go back to stock for now.
Do you have a recomendation for any free/downloadable stress tests?

Run Prime95 for cpu stress:

Keep an eye on temperature:
http://www.alcpu.com/CoreTemp/
Cpuz to check current clocks/specs:
http://www.cpuid.com/cpuz.php

You can set multiplier to 7x for 2.8ghz

Thanks alot, wish me luck hahaha

I have made the folling changes below, and I am running @ 3.2 at these setting with no real noticable heat issues. I will download and run a stress test later, but initially, my 3D Mark 06 went from 12451 to 14422 (still with only 2 gig of ram installed. Thanks for the help
