Does this look good?

I've never overclocked anything before, this is my first PC.
Has an Asus Z97-A, Noctua NH-U14S, 4690k.

This is pretty much what I followed to get what I did, didn't change anything in my BIOS that wasn't changed in this video http://youtu.be/QBfXruwe8w4
Tried the adaptive voltage afterwards and my PC couldn't get into Windows so I just left it on manual.

Synced all cores, x46, 1.275v, think that's about all I really did.

Just want some reassurance that everything I did looks good and that there aren't any other settings that need adjusting, didn't really know all of what I should have shown in the pics.

4.6 GHz is good. Voltage is not bad. Temps OK. Check. wink.gif

You are fine.

Extra info which can be completely ignored in the context of your question:

Did you search for the lowest stable voltage? When running a constant voltage I like to find the lowest stable voltage and run about 0.01 V above that. Your load temps are fine so this isn't needed but if you are going to fine tune it that is where I would start.

Does the guide have you turn off C-states or SpeedStep? SpeedStep does have a (very small) performance penalty if you leave it on but it saves power and should increase longevity. C1-E seems to cause very little or no performance hit for me so I like to leave it on.

I notice your uncore is still at 3.9, I am not sure how much performance you would gain by you could attempt 4.0-4.2 GHz on your uncore. Maybe don't bother as tweaking everything can become a never ending cycle if you get too into it. smile.gif

I'm at this now: http://imgur.com/a/Xz9UG

I posted this same thing on the LinusTechTips forums and was told my Vcorerefin voltage was too high, but I have no clue how to fix that.
They also said I should enable the XMP profile, so I did, and 4.6ghz became unstable, never lasting more than a few minutes.
Maybe if I knew what I was doing better, I could have maintained 4.6ghz with the XMP profile enabled.


Since your questions still all apply to my 4.5ghz OC, no, I haven't fine tuned the voltage to as low as possible yet.

The guide does not tell me to disable anything, essentially set everything in the BIOS to default and only change the multiplier, core voltage, and to sync all cores. I believe those are the only 3 settings it tells you to change, it mentions enabling the XMP profile, but says it can cause some headaches, which is why I originally left it alone. So besides those things, and my custom fan curve, everything in the BIOS is default/auto.

I can try adjusting the uncore, and if it fails I can always revert. It mentioned a 1:1 ratio is ideal, but didn't touch much on it.

Thanks for the reply, I was thinking nobody was going to help me here. Suppose I could have made a better topic title.

Do you know what kind of RAM you have? XMP is simply a shortcut but if you know what it said on the box it is much easier to suggest possible settings.

The 1:1 ratio for uncore might be ideal but it isn't necessary and you are very unlikely to get the uncore to 4.5 GHz, at least at reasonable voltages. It is better to clock the core higher than worry about its ratio to the uncore.

Your VCOREREFIN is a bit higher than I would think necessary but not very dangerously so. If you look below where you set the CPU voltage there are a lot of other voltages you can tweak. Simply set the one that currently reports almost 2V to 1.8 - 1.9V. I believe 1.98V is supposed to be the absolute max you should use according to Intel. You can also play with the RAM voltages there, up to 1.65V might help your XMP mode be stable.

It is probably good that you didn't change those power settings I mentioned, I think leaving them at default settings is probably best unless you are going for those last few points in a benchmark.

This thread really is quite good: haswell-overclocking-guide-with-statistics, it maybe more in-depth than you want though.

My RAM is "AX3U1600W4G9-DB"
http://www.adata.com/index.php?action=product_orderinfo&cid=5&piid=206

I cannot find the Vcorerefin, the highest voltage I could find was 1.776, the VCCIN/CPU Input Voltage in the BIOS.
I seriously question if my mobo even has an option for it, it's an Asus Z97-A, there is nothing called Vcorerefin or anything with a voltage that is displayed over 1.776.

I'll be sure to check out that thread.
post #6 of 13
I would think XMP would work with that memory, nothing too hard for the Haswell IMC. Try setting the DRAM voltage from 1.5 V to 1.6 V after setting XMP. If that doesn't help try turning up VCCSA to 1.02 V (or less as needed).

The statement on LinusTechTips that has you worried about VCOREREFIN:

"VCOREREFIN @ 1.92 is a tad too high (assuming that is really VCCIN/VRIN within the BIOS). Get it under 1.9, and you sir, have a damn fine OC."

Makes me think you shouldn't worry about VCOREREFIN at all; it isn't VCCIN/VRIN as we already know your VCCIN is 1.776 V. My VCOREREFIN is 1.936 and I have never seen anyone say it should be less. It is VCCIN that should be at or below 1.9 so 1.776 is not bad at all.

EDIT: I would also revisit your overclock after you disable the iGPU, my i7-3770K overclocks better with the iGPU disabled. It isn't a major difference but the iGPU adds heat and uses power, both of which can hurt overclocking.

Well that's good to know then.
I'll try to shoot for 4.6ghz+ again when my Gigabyte 970 gets here... which I'll also have to overclock, but that should be a lot simpler.

If I can't get my OC any further, at least I know I have a stable 4.5ghz and none of the things in HWinfo are crazy, the Vcorerefin was all I was really concerned about, and if that's fine and everything else is normal too I'm happy.

Thanks for all the help.

I'm glad I read that Haswell Overclocking guide, my Vcore voltages were maxed during idle, didn't even know that was a problem... apparently an effective way to pointlessly shorten my CPU lifespan.
Suppose that's what the Adaptive voltage would have solved that Linus said to do if it actually even allowed me to get into Windows with it enabled.

What's odd is in the "Official" Devils Canyon Owners Club overclocking guide, its power saving section makes no mention of C-States, C7 which I currently have enabled and seems to be working.
It mentions the use of EIST, C1E... wait... double checking it does mention C3/C6, apparently these can all be used in combination... thinking.gif
So I have like 500 options and combinations to save power? Nothing can be simple can it?

I'm just going to continue with C7 enabled and hope that's best, HWinfo reports the 4 Vcores with 0.000v while I'm idle now, which were 1.220v previously idle. Damn that would have sucked to have not figured out for a long time...
post #9 of 13
Constant voltage It isn't a big deal actually, especially at the relatively low voltages you are at. Your constant voltage will not damage the CPU any time soon, this is for decades type longevity not a few years. It is more of a theoretical worry than an actual one. If you were near 1.35 V or even higher it would be a bigger deal. If you are worried about this effect make sure to find your minimum stable voltages, high voltages will do more damage when under load.

The C-states are simply more levels of lower power when idle, more parts of the CPU turn off at higher numbers. C1E helps even when it is only a bit idle while C7 lowers power even more if you are pretty much completely idle. You might as well turn them all on unless one causes instability. Higher C-states can cause stability issues when overclocked, especially when using adaptive voltages. It also takes longer for the CPU to wake up out of higher C-states, it isn't very long but there is a measurable performance impact, maybe not noticeable but it is measurable. wink.gif

Thanks for all the help, I think I'm finally 100% satisfied with where my CPU is at.

Since you've been so helpful with overclocking my CPU, any advice or helpful guides like that Haswell one you have for overclocking a GPU?
From what I understand, it should be significantly easier.

My Gigabyte 970 G1 should be here tomorrow.

My exact plan is to first install the drivers, run the Unigine Heaven Benchmark and see if things are stable.
With the settings from this overclock: http://www.guru3d.com/articles_pages/gigabyte_geforce_gtx_970_g1_gaming_review,26.html
I will instantly set my settings to 50% of the increases they made over the default settings, they increased their core clock by 150mhz, so I will start with an increase of 75mhz.
I'll continue slowly increasing all the settings they've increased with MSI Afterburner, attempting to match their overclock, running the Unigine Heaven benchmark after every change.
That's about it, that seem right?

Also, will the GPU be similar with voltage, will I need to screw with it somehow so it isn't taking maximum voltage even while idle?

If you can help, thanks, I know this isn't technically the place for GPU overclocking discussion, so if I need further help I'll make a topic about this in the proper section.
