Doesn't work on Gigabyte motherboards.

It's unfortunate that if I use LLC, I cannot use EIST or C1 states, therefore decreasing the longevity of my chip.

You just need to use more offset voltage then to combat vdroop. Keep adding in increments of +2 until it becomes close to stable then start using increments of +1. You shouldn't have to worries about the voltage required for 4.5 GHz as it's not high enough to cause problem.

I'll just stick with LLC for now, thanks. It takes 0.030 V more than LLC to get it stable. Not worth it imo.

Another alternative is you could just raise the core and enable EIST or one of the other power saving modes and you will rarely hit the higher Vcore as the power savings state will lower the core voltage when not under load .

The guide does cover all possible issues for BSOD 124. It also covers the LLC issue if you were to actually read through the entire thing. The only thing you have tried is messing with the C3/C6 states.

Since you don't like to read and find things that could be the fault of this for yourself I'll point them out for you.

PLL.
VCCIO.
LLC.

LLC is covered at the bottom of the guide, if you think that is the problem.

Here, basically it's saying LLC may end up lowering your voltage too low, in which case you will need to have a different LLC setting.

You should enable C1E and Speedstep and see if that helps, as it doesn't effect overclocking or stability under load, so there is no reason to disable them. If you use offset votltage in combination with C1E and Speedstep it will allow the voltage to drop along with the multiplier when it's at idle, however some have found that using offset can cause idle random bsods because of the low votlage and how quickly it rises when it's under load. The simple solution to that would be to reduce the LLC setting a litle to maintain a higher idle votlage, but will require you to increase the vcore a little.
Here is an example of how LLC can affect idle voltage:
This is using High LLC (50%) and an offset of + 0.150:
Idle Voltage

Load Voltage (fluctuates between 1.472 and 1.480):

This is Ultra High LLC (75%) and an offset of + 0.110:
Idle Voltage
wCVF2.jpg
Load Voltage (fluctuates between 1.464/1.472/1.480/1.484):
dvjUw.jpg
As you can see the idle voltage when using a 'lesser' llc control allows us to increase the vcore so that the idle voltage is not 'too' low. When using ultra high llc, we use less voltage but get similar or the same load voltage but the idle voltage is much less. That could be what the problem was, im not sure. By the way, I have said this countless times, the bsod code list is not 100% accurate, 101 could be even qpi/vtt.
Hope that it helps you thumb.gif

Just out of curiosity, when LCC is off what offset do you need to get the peak load voltage that you want? And then while stressing, what VID do you see?

If you actually read what Piegoodman was saying you would have noticed that he can't enable LLC while using offset mode. This is the same for me so I know what he means.
