I still have to watch people with <~$100 air coolers get better results than me frown.gif

So - nobody has any comments re: SVID and leaving it on/off?

Also, what the hell is is IACore? XTU can tell you it's TDP usage (which for me under load is usually ~10W less than Total CPU TDP and HWMonitor shows it's volts as 1.31v which don't change during idle/load?

Well then that's very sad to hear. skull.gif

I'm now trying 4.4GHz and I'm already on 1.35v

Should I adjust to 1.8something? It's on auto but Hwinfo reports 1.80.

Try 1.9. I think I replied to this before (not sure though).

Did you pass x264 before crashing?

My H100 is mounted as outtake to suck air out of the case from the top of the case.

Upping it to 1.36 I can run xtu for 1 hour, 3 cinebench, and 3 x264 with temp being in mid 90c but I just say F it and let it run to see if I crash or not in that hour. Lately it been around 40 degree F here in NYC not sure what it will translate to in Celsius. Idle I am around 35-38 at 4.6 and gaming I will be in mid 60c max. I would like to test longer but the heat is what worry me and I might be bored but not bored enough to sit in one spot for 12 hours biggrin.gif
I have the setting saved in my profile and can get them once I get off work. For what I do 4.6 "seem" stable to me but just not sure so my safety oc is 4.5.

40F is pretty cold ambient (is that 40F in the house or outside though?) So you see a big temp variance from x264 to gaming, a 30C+ change. That's interesting. Which games?

Mid 90C, so that's 95C? If you're peaking at 90C you can still safely test x264, just eyeball the first pass, come back for the third pass, then the 6th and after that I doubt temps will ever get higher than the peak you got there.

I'm trying 1.36v and 1.9v for 4.4GHz now, thats almost +0.1v for extra 100MHz!

And just to think I still have to raise memory and uncore... I wasn't even hoping for a good chip, a normal one would be nice, but this one is underdog frown.gif

EDIT: 1h OCCT completed without errors, finally!

This is how hot cinebench get at 4.6. All fan set on high inluding cpu fan


Right now outside is 9c according to Bing weather app and inside the house is around 25c .

In term of games, it mostly WoW, D3 and LOL. When it get intense like raiding or a mtch my cpu only uses about 20% or under but temp will spike to mid 60c

You need to keep the VCCIN at least 0.500V-0.550V above the VCore. So right now, it is quite a bit below.

What's your Uncore speed and volts?

This guide has been helpful so far, but this is all extremely confusing for a first time overclocker. As of right now all I have done is change the Core Voltage to 1.235 and the multiplier to 43. It boots up and is Prime stable for an hour. Is there anything else I should change? I don't get the whole Uncore thing. I'm using a Maximus VI Gene and an i5 4670K, so I think Uncore is translated to CUP Cache in the bios. However, I don't really see any way to change the multiplier for it, although the voltage option is there. Can anyone with the Asus rog bios help me out?

Yes it could. Did you run a few passes of memtest to make sure your RAM OC is stable?

As Wiz mentioned earlier, there shouldn't ever be a need to have vring higher than vcore. The point that the guides make is to not raise uncore multi higher than core, not the voltage, thus making the question about raising vring higher than vcore kind of redundant, although if you ever get to a point hat you do take it higher there's something not right with your OC.
Are you leaving uncore dropped when OC'ing core?
Are you adjusting VRIN as well or just vcore? Have a go testing with x264 instead, it might give you a better idea of what's working or not when you make changes in BIOS.

That was actually a very good question. i don't think we had a good discussion yet about uncore voltage and why it should be set the way we setting it. For me I just know setting uncore volt at the same as vcore or higher bsod or my computer won't post. I am open to this discussion and I am interested in what other are doing to uncore. This is one part of haswell that I think really is new and hasn't been touch on much.

BTW my setting for 4.6 is vccin 1.85, vcore 1.36, memory at 1866 dram volt at 1.65 and ring volt at 1.17 with uncore at 42. So Cyro999 you were correct about my setting. But I did play with it as high as 2.0 and work my way down. I had it that low because I am under the impression that VCCIN also add a little bitt o heat and I am trying to find the lowest volt I can run and maintain some stability.

I want to work on the heat issue and then I really would like to do some serious stress test at 4.6. Maybe beat Dark to stable 4.6 tongue.gif or blow up the chip trying. If one thing I am sure about this chip, it is hot hot hot. devil.gif

Edit with pic on how hot it get just standing around WoW doing nothing

I just ran the windows memory diagnostic. First time I ever get this bsod code, and I was running a virtual machine which uses quite a lot of ram. I'm still not sure, 3b code isn't very well documented, but I'm going to bump memory voltage by 0.025.

You might want to try a better memory test than the windows one.
