Something is wrong here..

Is Hwinfo the latest version?

Their latest revision change log said it fixed some Asus issues.\

 

 

About Vrin:

If you doubt the data I have simply test it yourself. That way you get the answers you seek.

otl - If you're talking about bus speed here you should be able to lock it to 100mhz in BIOS.

I find this VCCIN thing weird i am running it at 1.75v and Vcore 1.24 for 4.5GHz i bumped it up to 1.95v / vcore 1.3v could not get more 100MHz out of the CPU in fact i will reduce VCCCIN even more to see the impact on temps

As far as testing goes i can't speak for others but i fully test to within .005v VRIN and .005vcore all the way when O/C'ing, sometimes less.

I've set LLC so it doesn't move under load/idle from what I set it to. But basically what I meant by "what does it cover" was that it's meant to cover all volts going to the CPU AFAIK. So vcore would be one, what would the others be then..? If you disable iGPU does that lower the "requirement" etc. It's like this magical volt that nobody knows much about and it's range is huge.

Too much can definitely cause instability. Questions i'd be asking are what setting is vdroop on, would +.06v on the core be enough for that chip getting to the next multi (what was x44 stable at?) / (Wiz- are you not around about here with yours?) and if you used x264, how far were you getting with it? I'd be surprised if it needed a jump of .2vrin at that vcore going by what i've needed myself. Wiz - what did you jump up from when you ran 2.0vrin?

This is all assuming uncore and ram were taken out of the equation.

I see what you're getting at. Vcore and Vring are the main two. High chance you'll get to a stage when you've increased either/both of these to a certain amount and won't be able to achieve stability due to vrin choking things. The higher you take core/uncore the more vrin you need, in some instances. Was going to say all instances but i think that would only apply if you had your core stable at the minimum vrin needed for that multi/vcore which not everybody has/does.

I've not really moved vring too much so not sure how much of an impact it has on vrin. For me when my core was running on optimum vcore and vrin i had to increase vrin by .025v when i started moving vring up from 1.15v. I've not adjusted it since and i'm now at 1.22vring so guesing core has a bigger impact than uncore on vrin.

With SA/IOD/IOA i'm not sure how much of an effect they have on vrin. I've only moved SA/IOD up to a max of +.1v/.15v and can't remember needing to change vrin at all to accommodate the increase. At one point i had +.15v on all three but couldn't stabilise at all, with an increase in vrin making no difference, ended up dropping IOA and all was good.

Not really found out much more than that myself, also still learning!

(EDIT - finding out SA/IOD etc can also cause instability if not dialled in right and just stetting them for .1v etc may not be what's needed. The higher i've been taking uncore the more i've had to spend time with these to get them spot on, and that's not necessarily increasing them!)

I've no idea what difference disabling the iGPU makes but i've had mine disabled from day 1.

It provides Vcore, Vring, VCCSA, VCCIOA, and VCCIOD.

Do most ppl run manual or adaptive for everday stable?

I run adaptive so there isnt 1.3V running when Im just browsing or idle.

Same, i'll be changing to adaptive for 24/7 once i'm done with the O/C.
