Haswell Overclocking Guide [With Statistics] - Page 214

I decided to give overclocking my 4770K a go, and from the stats in the first page, it seems I got an awful chip.

1.2V stock Vcore, and it seems to need 1.9V VRIN

You're probably just not good with OCing yet.. it's pretty hard to get everything down right and i'm still learning day by day 3 months later.

Add VRIN LLC (max or 1 level down from max) and try 1.25vcore 1.75vrin, manually set uncore to 34x (not 35x because it turbo's), as a stability tweak you can try using +0.05 or +0.1 on digital io instead of auto. See what multi you can get from a profile like that to start off

I get terrible, really terrible results if i set VRIN that high for lower vcores. My 1.76vrin OC that'll pass all of my testing indefinately will fail with 1.8vrin and need like 0.02-0.04vcore more with 1.9, assuming LLC. Without LLC, it'll bounce around a lot and change so much that you can't really optimize it

I might have to try the digital io myself and see how much more I can push them 780s ill be getting.

I'm at 4.5ghz stable with a 1.9vrrin, 1.27? Vcore, and 1.19 uncore set at 42x.

I say I've got at least a good little overclocker, just haven't gotten it to 4.6 stable.

I wouldn't mind running 4.7 daily once I get my chip delidded and set on a custom loop.

Guys, in terms of real world usage how much performance increase would i actually notice going from 4400 to 4500/4600?

I know it's hard to say exactly but do an estimate, and in fps during games, any?

PS, is this true?

Disable CPU Enhanced Halt (C1E), EIST (SpeedStep) & Cool'n'Quiet in BIOS

CPU Enhanced Halt (C1E) & EIST decrease overclocking reliability, create DPC latency spikes and hiccups in some circonstances.

Gigabyte motherboards note
Depending on your model & BIOS, Intersil power controllers may be defaulted to intermediate hardware power management, creating high DPC latency under some circonstances. Only way I found to fix that was to install Gigabyte Dynamic Energy Saver, turn it On then Off. Now optimal performance, minimal power management are set (even if you reinstall Windows). You can uninstall DES or disable the associated service after this is done. This may apply to other mobo manufacturers using similar PWM controllers and softwares.

Disable High Precision Event Timer (HPET) in BIOS

Are these tweaks still valid, i remember them having positive impact on my amd but that's a complete different architecture and all.

I was using Aida64's stress test. It's just failed about 5 hours into it too doh.gif.

I guess I'll need to go back and adjust some things- (maybe up the Vring?)

From the spreadsheet on the first page, the vast majority of 4770Ks are clocked 4.5GHz or higher, and only about a third of all the entries have a VID of 1.35V or above.

It could be that I just haven't got the correct settings dialled in yet, but my 4770K does look subpar right now.

I've been following Sin's overclocking guide for Gigabyte motherboards. The LLC is set to extreme, but I'll give the other settings you posted a go.



Thanks to everyone for helping!

Don't use windows on balanced, atleast i had this problem.



Edit, not allowing to throttle only solved it partially, i still seem to have insane amount of page faults, why is this? Is it because of a bad overclock?

Uninstalled Intel Rapid Storage, much better. But still high..

Page faults are not a problem normal puter usage if you dont have enough RAM and the system has to use the page file.

Well pagefault's affect the dpc latency, and i'm not sure how much is normal but im sure 8GB should be enough.
I'm curious if someone else could do me a favour and try to see what they get, that way i would know if it's a problem on my end only.

There is 1 for 4.3ghz.

There are 3 for 4.4ghz.

There are 4 for 4.5ghz.

There are 2 for 4.6ghz.

There are 4 for 4.7ghz.

There are 3 for 4.8ghz.

There is 1 for 5.1ghz.

 

Keep in mind I only started picture verification halfway into the thread.

So there are 8 that are 4.5ghz or under but there are 10 that are above 4.5ghz.

And my guess has always been, average is 4.5/4.6ghz.

 

I've had to deny a few overclocks simply because they didn't include picture of Vcore, etc. but if I count those I'm not sure what the end would look like.

 

EDIT:
If we go by median overclock that would be 4.6ghz on the dot, I just realized. 1 for the highest and lowest, 3 for second highest and lowest, then 4, at middle 2.

If you also look at median results on my chart regardless of picture verification, that would be the 33rd result, and that also is 4.6ghz.

Most page faults aren't the page file and memory running out nowadays. There's a method called "memory mapped files" programs can use. Windows will mirror the contents of a file into the program's memory. It will only make a note of that, not load anything from disk. It will use page faults to load snippets of the file into RAM the first time they get accessed. The page faults are nothing bad, it's just the name of the processor feature being used.

Basically none. You might see the difference in benchmarks and some very CPU intensive tasks, but for normal use the CPU is hardly ever the limiting factor and that small a difference will be meaningless.
