If I don't need for 0.5V lower Uncore voltage than ram voltage rule on haswell,
there is no need for me to put 1.15V to uncore.

thanks anyway smile.gif

Ah okay, well I've never heard of that rule, IF it helps I run my Uncore at 1.2V (Adaptive) and my RAM at 1.6V (at 2400), since I got my system 3 years ago.

It's from @Sin0822's OC guide, God bless him.
The GIGABYTE Z97X Overclocking Guide

The photos / screenshots in that guide do not appear any more. I had it saved on my computer.

That's a different table. The one I'm asking about says VRIN Override should be at least 0.8v delta over VCORE. I know for a fact that's preposterous, which led me to call the table into question right away. Then I looked at some other values and even if they are safe, they're irrelevant, like 1.45v max VCORE on air; you'd hit thermal limits before you could ever get to an OC that would legitimately require 1.45v, even if you had delidded. Hell, I'm delidded on custom liquid and pushing a 1.404v OC has me hitting 80C under load. I know every chip is different but no amount of good fortune is getting you to 1.45v OC on air, unless you're holding back on the clock just to prove a point, which means you wouldn't have needed (or utilized) 1.45v. But if people must include that value in charts, I suppose it's like saying that leaving all the lights and faucets in your house on 24/7 is "safe." Sure, be my guest. But the 0.8v minimum delta is just plain erroneous.

I'm just wondering where that exact table came from. It has the look of a real table, but it's clearly a sloppy imposter and should not be disseminated. This is the sort of thing that causes confusion.

You're right, my bad. My Google-foo has not led me to the origin of the table.

Lol, I didn't pay attention to actual values in this table biggrin.gif, Dear table, you are not getting me to run 2.1v VRIN for just 1.3V core votlage, just no tongue.gif
I am running haswell for 3 years+ now and gained some good understanding fo what is really safe for it and what is "safe" and what is not for long term use.
(my everyday usage, probably my 1 month of use equals to at least 2 or 3 months of use for most users)

I degraded a 4690K running 1.8v VRIN, 1.26Xv (can't remember last digit) @ 4.4ghz, 35X uncore 1.05V and everything else auto 1.5V XMP Ram
It was set borderline stable, 1 notch lower voltage, it would 0x124.

took exactly a year, a full year without single BSOD, started to bsod 0x124, once a day. Fixed it with 1.9V Vrin and 1.125v uncore @ 35X, used it 4 more months that way.
so degradation happens but not a big deal, it took 1 whole year of heavy gaming (long periods) to de-stablize a borderline overclock.

I bet I can degrade a chip @ 1.35v in less than a year if it is set borderline stable tongue.gif just by using it biggrin.gif

That 4690K died afterwards so data ends here, not because of overclock or anything related to voltage, it is a long story rolleyes.gif
Total lifespan was 2 years, exactly.

My uncore is at 1.08(4Ghz) and my rams at 1,64.
No problems and runs stable.
