4.7ghz

30 minutes initial stabilization check--usually within the first 10 minutes I can tell if I have enough VCore.
Appreciate the advice--your original post was incredibly helpful. I came from my last OC during the days of a Pentium IV. Since then I've just put it off due to family and my gaming system wasn't really mine. So again, thank you and everyone else for the amazing information.

So, back on topic. VCCIN is at 2.0. VCore is at 1.385. Multiplier 47. Current export of 31 minutes 49s of OCCT is included, lots of graphics and all the goodies.

I've uploaded the useful images I believe.

Still want to break that 48 to 50 multiplier range. I have some CLU on the way and will be de-lidding my processor once it arrives in the next week or so, this should give me an additional 15C headroom. Running a x264 benchmark next, though I believe my everyday use would be good test.

Giving up on 4.8ghz, not comfortable with 1.45 + vcore on air.

Here's my 4.5 Mr First Post. I'm too lazy to run prime and IBT again (stable with both but both take too long to run) so here's an x264 quickie.

Im having the input voltage already at 1.95 when the bsod happend. So doubt I will see any changes with 2.0 there. Its just RNG luck, will go back to play gw2 for my RNG luck to get my legendary instead tongue.gif

I know that 1.95v to 2.0v sounds like a small increase, but it can really end up making a world of difference in the stability of your system. Even going from 1.95v to 1.97v could mean the difference between unstable and stable....thumb.gif

1.079v for your VRing? Where are you getting this reading from, and what multiplier are you using for your Ring/cache/uncore (whatever your board is calling it)? That is awfully low....thinking.gif

Say what?

I was perusing the sensors and noticed CPU Cache as a voltage so I'm assuming that is it no? It's currently .01 higher than what was set in the BIOS.

Latest and greatest OC HWiNFO.

Core Multiplier: 49
Core BLCK: 100
VCore: 1.39
Uncore Multi: 35
Uncore Voltage: 1.055
Vrin (I believe this is VCCIN): 2.0
LLC: LB (Will verify this in a second).

Currently this is unstressed and untested, will be doing testing here in a bit.

Stable settings for my 4700 mhz:

Core Multiplier: 47
Core BLCK: 100
VCore: 1.38
Uncore Multi: 35
Uncore Voltage: ASUS Auto, forgot to log it.
Vrin: 2.0
LLC: LB

Nothing too dramatic or extreme on the stress tests, just OCCT for an hour and 30 runs of x264 overnight.

Okay, will try that tomorrow then, is a 2.0 considered safe? (2.2 was unseen territory).

Hey now - let's not go calling your CPU any names ok haha.
1. Did you raise your Input voltage to scale properly with your Vcore? I think you could probably still gun for 4.7, if you're comfortable handling 1.36vcore.
I'm just making a rough guess, of course, if your chip scales like mine (albiet +0.1v). Your VRIN at 1.36 would probably be more like 2.05, or 2.1 though. Confirm this by watching the BSOD codes of course though.

2. You should consider running the looped bat file instead. This will use the more stressful part of the x264 bench for as many loops as you direct it to. Start with 5 loops (55m-1hr). And then if you can pass that look to 20 loops or overnight (40+)...though 20 loops is already alot haha.

3. For the higher overclocks, I think you will want to manually set that LLC setting. I'm downloading the manual right now to see what the other options are, but you'll want to ensure your VRIN is staying at where you set it especially for the higher overclocks which need more VRIN.
Looking at your 4.5Ghz data, it goes as low as 1.74 and then as high as 1.792. So there is some droop occurring - on AUTO anyway.
*Ok almost forgot DarkWizzie also has an MSI board haha. Seeing as how he described the 100% behavior in the first post, you will definitely want to set LLC to 100%.

I've back read a few 1000 posts and been following along on this thread. First thanks Darkwizzie for starting it especially the idea of keeping the data in one spreadsheet one can download.

One of the more interesting points I see emphasized here is the relation of Vccin with Vcore. While I read elsewhere the usual "keep Vccin +.4-.5 above Vcore", this thread suggests an even tighter sensitivity between the two. I took the data spreadsheet from the first post and decided to plot Vccin to CPU VID. While Vccin was only provided from some of the lines, I think there is enough to draw some conclusions.

From a linear relationship point of view, the data would suggest CPU VID + .6v is the sweet spot for Vccin.

Trying to apply a polynomial relationship, it might hint that even more is to be added above 1.325 Vcore, ramping even higher with larger Vcore. But I think the data above 1.4 Vcore is a bit questionable given the lack of data points.

Tried input all the way to 2.2, I still get 101 BSOD within minutes of running x264

Dear sir or ma'am, I think I have what is called a POS CPU

Yes at idle the vring (cache voltage) is what I posted. But it will increase to some extent, depending on how hard the cpu is being stressed. I've seen it go to 1.080 at that setting but not much more. I have it set manually, but only slightly above the "Auto" setting of 1.05v....1.055/1.060, basically about the same.

Currently I'm running x39 uncore.

Don't know what boards you guys are running, and I don't know anything about the settings on non-Gigabyte boards , but I'm very familiar with my UD5H board settings.

Right now I'm back to running 4.9 stress tests to try and get a better handle on those settings, but otherwise I can get it rock solid at 4.8 with the settings I posted.
