I never stated it wouldn't work, and I personally have not, but have read posts about haswell chips dying above 1.35. Ill try and find the links.

There are lost of people running 1.4 or higher vcore for alot longer than we have look it up

You said "for everyday use the chip will die faster"... These are the claims I wish would stop. How do you know this? No one knows. If you show a story of someone I am all ears, but until then, according to Sin's guide, his numbers say I am perfectly within limits.

And yes, I am on a full custom loop and my cpu is de-lid. Have a 60mm 420 and a 480, both in push pull cooling the cpu and gpu only. Max core temp spiked to 80 C last night - run an avx miner all night with the gpu miner (both cpu and gpu at 100%).

Again, no offense to the OP, but in my experience VCCIN has has little to no effect on my stability. I'm sure it has something to do with the fact it has to be within a range at some point. I have found, really, the only voltage that matters most is VCORE. For example:

Right now I'm stable at 48x, uncore at Auto (40x), Auto uncore voltage, VCCIN is at 1.9, VCORE at 1.475. I can change that VCCIN to 2.0, 2.1, 2.2, 2.3, It will literally have zero effect on anything INCLUDING temperature. My max core temperatures will not change. Now, keeping the same settings but change VCORE to, say, 1.400, I will get a BSOD of 124.

For stability I use my CPU miner with the GPU miner, as well as BF4. Occasionally I will use XTU or AIDA64. And before you say it, no, I will not use the X264 benchmark. Reason? If I am not gaming on my pc, I'm mining. Not going to sit there and let it run for days not doing anything productive.

Edit: I'm fully willing to try anything so if you have a suggestion, I'm all ears. But as for stability, I'll decide that. Also keep in mind, like I said, my pc pretty much runs full blast all the time. The only game I play is BF4.

Ok, was trying to get my stable overclock of 4.5GHz to 4.6-4.7 today. At 4.5GHz with 1.275v I upped the voltage to 1.3v for 4.6 BSOD at first pass x264 Wen't back and added 1.35v same thing happend went to 1.385v still no luck finally just to see if I could even get it to run with more voltage I put it to 1.45 and still BSOD. uncore is at 45 with 1.3v downclocked my ram to 1333. Can someone help me at least get to 4.6? 1.45v is the most I feel comfortable with.

I would bet you won't be able to run that UNCORE that high. I'd set it to 39x and try the CORE at 46x, 1.3 VCORE.

I'm running 1.42 vcore for my 4.6 overclock. Been so for a month with no ill effects. I also bought the Intel tuning plan, so I don't really care what happens tongue.gif If I'm lucky, it'll die and Intel will send me a better chip.

Vccin influenced my OC as you can see by my posts, on my 4.4 when I changed vccin as you advised I bsod like 5 mins into a stress test, same as not happened so far at higher settings, so its not that linear imo. I could be wrong tho

Thought it was worth a try. I've never run anything less than 1.8. If that VCORE is what it takes for stability, you may just have to back off to 43X if temps are still too high.

Awesome to see you're mining like I am, using CPU. I assume you're using MinerD? Are you getting 24/7 stability out of it? If so, what are your BIOS settings currently?

Thanks.
