OC 6600K

[Simpsj17]

Right now I have my OC set to 1.350V at 4.6 Ghz. When I look at my CPU voltage it only shows 1.14V at 100% load. Does this mean I have more headroom to OC with. I thought about going for 5.0. thoughts?

It means you're having some serious Vdroop

Assuming this is at manual voltage, what stress test are you using?

Also be sure to set your LLC to a reasonable level like 5 out of 10.

wow lucky. I got my 6600k at 4.2 with 1.3V

For manual voltage and stress testing using something like realbench or Adia 64, see if the voltages are still lower than the set amount if so then check the LLC to see if it's very low if so that can cause as mention vDroop but that seems like a lot.

I tried going up but it just crashed and wouldn't even boot the bios, but it pass all the stress test at 4.6 and it gets to about 60 C and stays there for over an hour. I'm thinking its best to stay at 4.6. thoughts?

What voltage are you at right now, I wouldn't push it past 1.35V in most situations even with liquid or large air coolers.

im at 1.35 with LLC at 5 but my voltage doesn't go over 1.14 mabey it is reading the SA?

Might be an error with the software readings then it should go up to the set amount on manual mode without question even with V droop it should not be that large of a difference. Maybe try resetting the CMOS to see if that kicks it back up and going, I remember encounter something similar where there were no changes in the voltages from stock when I was overclocking a system for a friend of mine.

I think that your right when i looked at the UEFI it showed Vcore of 1.360. The software I am using to monitor is NZXT cam due to all my cooling being NZXT products.

Use CPU Z to see what you get that is usually the one I trust the most but I've also had it give errors before so it's not uncommon.

sure enough, as soon as I load up CPU-Z low and behold Vcore is 1.368. Thanks for the help! Hopefully NZXT will fix this.

Ok so it was just a software issue, I would suggest to low it a bit though as if your doing an everyday overclock a good rule of thumb is around 1.35V with good cooling.

I dropped the frequency to 4.5 and got it stable at 1.320 max vcore versus the 1.368 max vcore. Any idea as to why it was able to drop so much vcore from a .1 difference in ring ratio. Or is this a silicon lottery situation?
