Vcore

Once you have reached a stable clock with OCCT or Prime can you then back the vcore off if you are only gaming, seeing as there is no way you would be 100% full load in games.
If so how much can you back off, to keep a stable gaming system.

If you've got it stable by increasing Vcore notch by notch until you passed OCCT or prime, then I recommend you don't decrease vcore. But, you might as well try it, and if you get bsods or restart, you will know why.

Bear in mind that vCore too low can manifest itself in other circumstances than 100% load. I would never back off personally.

my experience is that even though i passed orthos i still had to slightly increase my voltages as i was still getting lock ups in games! so i would not personally decrease them.

Surely, this is the whole point of stability testing? I can boot into Windows and run SuperPi at 4.5GHz with an E8400, but it won't run 30 seconds of Prime or F@H, so it's not really stable.

The first time you've just finished a level of a game that doesn't allow you to save in-level and it crashes and you have to do it all again, that's when you realise how important stability testing is.

Backing off the VCore on a stable sytem is a recipe for unhappiness.

Well maybe so, maybe not, but I need quite high volts in bios 1.44375 to run OCCT stable for the full hour, which equated to 1.36v underload because of Vdroop.
Last night I dropped the vcore in bios to 1.4250 (1.34v load) (OCCT 4m 17s) and fired up fear and it worked flawlessly for over 3 hours.
So its a tricky one as the rig seemed fine, so people should try it out as you might be putting more volts than you need for gaming.
I dont think gaming use 100% of all four cores all the time, as it is mostly GPU.
Its a risky one to try, but gaming is not that important to me, so if I have to restart a level so be it, well apart from online GTR2

Yes, but as WJA96 said, the whole point of stability testing is to find your system stable. If you lower voltage, you know it will not be stable. I may that mistake believ me, I lowereed volts a bit, and it played all my games flawlessly. But, I was defragging my hard drive the next day and it blue screened when it was defragging the windows directory. I had to reinstall the disk image, because it windows refused to boot.

What I'm saying is, if you want to risk it, go for it. But don't cry when it'll bsod when you perform an important action on your pc.
