Welcome to the new thread! It has been updated to reflect the latest findings. If you have already reported your unlock in the original thread, DO NOT repost! You are already included! Feel free to comment or ask quick questions about your or other's unlock. We do encourage brief discussion, since it often provides more information. Please comment or make inquiries. However, please do not use this thread if you are having major difficulties with your unlock. Please start a new thread for that.

READ THIS FIRST! And make sure to use our template to report results ↓scroll down↓
Before you attempt to unlock your CPU by setting ACC (Advanced Clock Calibration) to "Auto," please make sure you go through this checklist:
1. Turn off Cool N Quiet
Re-enable later if you want
2. Boost your vcore by ~.05V.
You should have at least 1.35V going to the CPU initially. I personally prefer 1.4V with a good cooler. Most boards have an "add voltage option" e.g. +0.05V, +0.075V, and an "adjust voltage" option, e.g. set voltage to 1.35V, 1.375V, 1.40V, etc. Use the "add voltage option"! Doing so will allow you to more easily enable CnQ later, since this option often adds the "plus volts" to every clocked-down mode in CnQ.
3. Do not touch your CPU's multiplier or try to OC your system!
Make sure you set up your system stable and 100% functional before attempting to unlock! Eliminate all other variables! Are your RAM timings right? Is the system Prime/OCCT/any other stress test stable in the first place?
4. Your CPU temperature reporting will become screwy after the unlock (-256C). This is normal.
Most BIOS HWMonitor functions still work - use those. Depending on your mobo, programs like SiSoftware Sandra or Everest might work.
5. Do not use the stock heatsink. Do not use the stock heatsink. Do not use the stock heatsink. Do not use the stock heatsink.
Yes, we know there are exceptions, but a good cooler is a sound investment. The stock HSF that comes with the lower-end Phenoms/Semprons is NOT a good cooler and can make an otherwise 100% successful unlock unstable or even fail under load. Furthermore, the inability to monitor temps while at load in Windows means you have no idea what your load temps are when unlocked. You want a large "safety net" in this regard. A list of quality heatsinks can be found below. Head on over to the "Hot Deals" and "For Sale/Trade" forums for help getting a deal. Trust us, it's worth it. For a more detailed mathematical explaination on why you need a good HSF, click here.
6. Most boards have multiple ACC settings.
If "auto" doesn't work, try others.
7. Make sure your motherboard has adequate voltage regulation.
Test this with OCCT. When it completes its run, look at the graphs for the variation in the voltage of the processor at full load. If it doesn't vary much, then you're good. But if it does, that's a sign of poor voltage regulation. Another sign is having a lot of vdroop. The higher the power phase on your mobo, the better. If in doubt, stick to name brand motherboards like Asus and Gigabyte. Look for 8-phase power designs, or higher. Also look for cooling on the mosfets. A lot of cheaper boards do not come with heatsinks on the mosfets. When mosfets overheat, they still "work" but provide unstable voltage to the CPU, causing instability (and even death). With a little 80W dual core, it's not an issue, but for your shiny new unlocked and overclocked quad-core monster, it will make a difference! Several options are available out there, but we recommend cheap, simple BGA heatsinks.
8. Make sure you have a quality power supply.
This may seem like a no-brainer, but bad power is bad power.
9. If all else fails...
These desperate measures might help:
Underclock the CPU
Disconnect all case fans from the motherboard
Disable hibernation in Windows
Raise/lower the Northbridge clock and/or HT clock
Bump your north bridge voltage slightly
Re-seat your HSF
Re-seat the motherboard power connectors
10. Be prepared for the reality that you are not guaranteed an unlockable CPU no matter what motherboard, bios or CPU stepping you have.
But we like those odds, don't we

Once you have completed the necessary tasks, please fill out this template for reporting your unlock pass/fail.
Please report STABLE successes only. If you are still stability testing, don't report until you know for sure. Even if your processor failed, we still want to hear about it!
Those who omit mandatory information will not be included in the database!
*Note: Henceforth, dual cores that only unlock to triple cores will be considered "successes." It is such a low percentage of processors that pass with three cores and fail with four that it is not worth the time or effort to distinguish them.
