Now, this is MY checklist. It is not required to overclock....many people have good luck with their method of just picking the FSB they want and going for it. I find this method works for me, and I believe it yields more stable overclocks, although it is incredibly time consuming. Nothing good comes easy though.



BREAK-IN PERIOD
  • Leaving all settings at default in BIOS, let the system idle for 8-12 hours. During this time you can use the internet or listen to some music a little, but no heavy stress on the system (no iTunes!! lol)
  • Turn the system off for 4-8 hours to let it cool
  • Run the system at 50% load for 24 hours. I use folding@home, setting the CPU useage to 50% for each console for this. I tis important to stress each core of a dual core CPU the same. While simply running one Stress Prime test only stresses the CPU 50%, it is strassing a single core 100%.
  • Turn the system off for 4-8 hours, letting it cool completely
  • Run the system at 50% load for 2 days
  • Turn the system off for 8 hours to cool.
  • Run the system at 100% load for 8 hours. Make a note of the vCore reading while under load, remember, all BIOS settings should be at default. You will need this reading for the next stage.
  • Turn system off for 8 hours.
  • Run system at 100% for another 8 hours, then run it at 50% load for 4 more hours.
  • Turn off system for 8 hours.
  • Run system at 50% load for 4 hours.
  • Run system at 100% load for 12 hours.
  • Turn system off for 8 hours.
  • Run system at 100% load for 2 days.
  • Turn system off for 8 hours.

This concludes the break-in period for all the system componants and also helps start the curing process for the Arctic Silver 5 thermal compound.

STAGE 1 - BASELINE VOLTAGE TEST
  • Take the reading you took of the Vcore used under 100% load and go into the BIOS.
  • Change the Vcore setting from AUTO to 3 steps under that reading. For example if your reading showed 1.28v under load, and your motherboard offers you the option of 1.28, 1.275, 1.25, 1.245, and 1.2375 as vCore options, you should set the vCore to 1.245, the 3rd choice lower than your reading.
  • Run 2 instances of Stress Prime 2004 for 12 hours.
  • If it passes 12 hours, go into BIOS and lower the vCore setting one more notch.
  • Retest for 12 hours with dual Stress Prime runs.
  • If it passes, go into BIOS and lower the vCore another notch, test with dual Stress Prime runs.
  • Continue this until it fails a 12 hour dual Stress Prime test. I usually recomend turning the system off for 8 hours after every 3rd test to let it cool.
  • When it fails a test, go into the BIOS and set the vCore at the last setting that passed 12 hours of dual Stress Prime tests. This is your baseline voltage.
  • Go into BIOS and take the chipset voltages off AUTO and set them to their lowest settings, then run dual Stress Prime tests for 12 hours.
  • If it passes, move on to Stage 2. If not, increase the northbridge 1 step and retest. Change only one setting at a time, and continue until it passes a 12 hour dual Stress Prime test.

STAGE 2 - CPU OVERCLOCKING
  • Go into BIOS and set your RAM speed to it's stock setting. This will lock it from increasing with your FSB and causing possible instabability.
  • Set RAM timings to their stock settings, do not leave them on AUTO.
  • Set your RAM voltage to it's stock setting, do not leave on AUTO.
  • Lock your PCIe bus at 100, and your PCI at 33.
  • Increase your FSB 5Mhz.
  • Exit and save changes, boot into Windows.
  • Test system with dual Stress Prime 2004 runs for 12 hours.
  • If it passes, enter BIOS and increase FSB another 5Mhz.
  • Test system with dual Stress Prime runs for 12 hours.
  • Continue this, turning it off for 4-8 hours between every 3rd test, until it fails a test session.
  • If it fails a test, go into BIOS and increase the vCore 1 step, then re-test.
  • Continue until you reach your maximum temperature or maximum safe* voltage.
  • If you are at your maximum vCore or CPU temp and fail a test session, you can go into BIOS and bump the northbridge voltage and re-test at that FSB again.
  • If higher northbridge voltage allows you to pass the previously failed test session, increase your FSB and test. Note, you may need to look into active cooling for the northbridge if you need to increase the northbridge again.
  • You have now found your highest, stable CPU overclock.

STAGE 3 RAM SETTINGS
This stage greatly depends on what RAM you are using. If your RAMs stock frequency is lower then your highest stable FSB, for instance DDR2553 with a 300FSB, then you will need to follow section A. If your RAM is faster than your final stable FSB, then follow step B

STEP A (RAM slower than FSB)
  • Increase your RAM frequency 1 step over it's stock setting, do not adjust RAM timings or voltage. If you can select any frequency you want, set it 10Mhz higher.
  • Run a dual Stress Prime test for 12 hours.
  • If it passes, increase the RAM frequency 1 more step (or 10Mhz), and re-test. If it fails, increase the RAM voltage 1 step and re-test.
  • Continue making only one change at a time until you reach a 1:1 ratio on your RAM and FSB, for example, 300FSB would match RAM running at 600Mhz, or until you are at the maximum safe* voltage.
  • Once you have found your highest frequency, adjust your timings down 1 step each, testing each change. For instance if your stock timings are 4-4-4-12, set them to 3-4-4-12 and test.
  • If it passes, set them to 3-3-4-12 and retest.
  • Continue until a test fails. The last settings that passed are your tightest timings at 1:1. The best performance setting.

STEP B (RAM faster than FSB)
  • Set your RAM frequency to match your FSB. No need to test this change.
  • Adjust your timings down 1 step each, testing each change. For instance if your stock timings are 4-4-4-12, set them to 3-4-4-12 and run dual Stress Prime tests.
  • If it passes, set them to 3-3-4-12 and retest. If it fails, increase the RAM voltage 1 step and re-test.
  • Continue until you are at the maximum safe* voltage. The last settings that passed 12 hours of Stress Prime are the tightest timings.

Now, your system should be at it's maximum performance settings.


* Safe is a word that has different meanings depending on your point of veiw and expectations for your system.

wow that was quite a reading, i'll give it a try and see what i can get. do i still need to do the break in part when i've already used the cpu for a while?

I told you it was time consuming, I've had my E6700 for about a month now and I am still at the Baseline Voltage stage.

If the CPU is not brand new, then the break in stage can be skipped as that is merely to ease the new CPU into operation.

Fat fingers. Missed the 8 I lowered it to *8*
