At least this was the same behavior when I had the old P8Z68-V. I'm sure though that 1.5V and the direct setting of DDR3-1600MHz worked with that old board and it doesn't with this new board. But it is really weird since when it is set to Auto the computer can boot without problems. Should I make my own thread about it?
Yeah might be a good idea to create your own thread.
Thank you for contributing to the thread and welcome to the club. I will update the spreadsheet in a moment,

Are you going straight to 5ghz or from a stable multiplier? if so, I will highly recommend that you try for a lower overclock first. Have a little read on my Sandy Bridge guide (link is in my sig).

Regarding Offset and LLC again. Say you need negative offset, how will High LLC and Ultra High LLC affect the voltages then? If I understand correctly, it would be better to use UH LLC for negative offset because it subtracts less voltage from VID thus higher idle voltage to avoid lockups? This is as opposed to using High LLC as a better choice for positive offset.
I also want to confirm that if offset voltage is changed, as long as the multiplier is fixed at a certain value the VID at load will not change, am I right?
I think I must've mentioned to you before that you should be setting the timings, voltage and frequency manually if XMP doesn't work.
Higher the LLC the more it compensates the voltage under load
not idle, therefore the lower the LLC the more voltage you will need to compensate it under load, this in turn increase the idle voltage aswell. Either way, negative or positive, I think the less you use LLC the more voltage you will need and that affects both idle and load voltage. Offset works off the VID and I believe the VID changes according to the multiplier.

Once it does this, it won't boot into Windows. I have to turn it off again and turn it back on to get it working. I've tried many different settings but haven't really been able to pin point the issue. I am also getting random BSODs in games or stopped working errors.
Today though... it just would not come on. I had to reset the BIOS and after I returned everything to stock I tried to go into windows and got a x007 BSOD.
Any thoughts on what might be wrong? My specs are in my sig.
Make sure all mother drivers are up to date. Is it a fresh OS install?
Thanks bud, I'll add you in a moment.
