Golden 4790k?

Heya,

I think I might have one of those "Golden" 4790k's, When I switched to Intel again not long ago coming from a AMD 8350, and previously a C2Q Q9450 I did a lot of research of overclocking this new chip.

I've seen a lot of people reaching 4.8Ghz with around 1.3v give or take.

However, I was able to clock mine straight to 4.8Ghz with 1.225v and was quite suprised to find it was stable with everything I thrown at it, mix memory overclocking and it needed one notch increase.

So I've tried 4.9Ghz @ 1.248v for the past few hours today running RealBench and again it seems rock solid, as well playing GTA V

I wonder if I'll hit a voltage wall trying for 5Ghz?

Who knows!

Haha! Thanks man!

Been busy preparing to relocate after taking a new career, I still lurk around for quick news but should hopefully more often soon! Certainly not forgetting OC3D Crew :D

Guessing that not all chips can achieve this?... not that into overclocking :p

Not that I've seen, I've seen some other low voltage high overclocks on this chip but not many, most (Correct me if I'm wrong) require around 1.3v to achieve 4.8Ghz.

Okay cool cool... just a tip though, to not get the mods on your ass... use the multi quote next time and combine both posts into 1, rather than doing double post :)

Great to see you back dude, and that is a epic overclock you have there.

Thanks!

I tried 5Ghz but as predicted I hit the voltage wall.

It took 1.3v to get to desktop and lasted half way trough Cinebench, then crash.


I will give 1.35v a try, but then I have to weigh up the pro's and cons. To be fair, 100Mhz and substantial increase in voltage & heat isn't warrant enough to leave it like that for 24/7

However, having the Maximus VII Formula board there's a mammoth of options I heavily don't understand that could aid me to get a stable 5Ghz with less volts needed, but will need to research that.

For example, I know that Input Voltage can be adjusted, but I've yet to have a play with this.

I'll keep you all updated.

This is all turning very interesting dude, even for someone who knows nothing about overclocking... well some small stuff. But yet, very interesting! :)

I'm subbed! :)
 
with all this Auto oc and "boost this for you to make life easier" and all sorts of other noob friendly stuff they add to a bios these days, I have to run OCCT and watch the voltage readings..
Quite often the board bumps up voltages some where which causes it to go way above what you manually set the things at.
and then you have to go back and tweak the crap out of everything to get it to actually use the voltages you THINK you had it set at..

I dont mean to be a naysayer here. But its not like the good old lga 775 days of I will set this here. and change this multi to that and change this frequency here and then change this ratio to that.. and then the computer just blindly does what you told it to which would let you know if you did something wrong pretty instantly by not being able to boot..

these days with overclocking apparantly becoming things that and one can do the motherboard will usually try to cover for you and up this here and tweek this there.

so please for your own peace of mind check what the voltages at the cpu under load.
and the higher the load the better imo.
I happily open occt for the nice layout for the voltages then run IBT.

i know people say "trust what the bios says over what an app says"
but the truth is under load the voltages do change and this is really just so new users get to over clock a reasonably stable system with ease..

i wish that what i set in the bios was actually what i got, but its not. and you have to set more than 1 parameter for voltages to get the load voltage to be the max voltage you wanted. and then what you thought was max voltage is usually considerably lower than that.
And as a result the clock speeds drop a bit.
 
Exactly, and to be fair, I've never ever bothered with Auto.

Sometimes it can work well, most of the time it does not and will over-volt. However it has come along way since the LGA 775 day's (Especially LLC, I remember LLC had no adjustment on my Striker II Extreme and would overvolt like crazy)

I usually always set most if not all voltages manually to their stock value, or what is needed to run at my particular configuration. I believe this is good practice to knowing what voltages should be at, rather than leaving it on Auto and leaving you to figure out for example if the Chipset should be running at that particular voltage or not...

Also, it's good to note that even the BIOS/UEFI Readings for the voltages aren't entirely accurate either. Hence why using a multi-meter on the designated points on the motherboard (If they have this) is always good.

Thing is, the last Intel chip I had was the Q9450 based on LGA775, then I went to AMD 8350 (Clocked @ 5Ghz), and thus in the meantime Intel had changed a lot of how things worked in terms of overclocking, ie no FSB as such, Uncore voltage, Input Voltage, etc etc.

When I first booted this machine and headed off into the UEFI I was just taken back at all these settings I had no idea about! Yeah I knew the basics of overclocking Devil's Canyon / Haswell as research before I bought the hardware, so I'm having to learn a lot again.

But sure is good fun!
 
its things like llc and so on you have to watch out for. "things that try to handle v drop etc"
you have to check what its actually doing under heavy load compared to what you THINK it should be doing due to what you set it at..
I guess not all boards are created equal but from what i have seen they all pump out more than you think they will with the manual settings you used under heavy load.

Try 1.295 in BIOS for a 24/7 stable 4.7 GHz.... Also, unlike the earlier incarnations of i7, Devil's Canyon seems to have little correlation to batch numbers, although, there is a LARGE number of nice ones coming from the Vietnam plant, just not mine.

I think 4.8 @1.325 (not tested much, still needs tuned, as I've been focusing on 24/7 stability under all load conditions on every increment below 1.3V for now).

I'm settling on 4.6 GHz @ 1.245Vcore / 4.3 GHz @ 1.200Vuncore for 24/7 use.

Just because I can boot winblowz and validate 5.0 GHz @ 1.425V doesn't mean I'll use it.

I'm a bit more anal about verifying an overclock than a lot of people, as I do more than just gaming. My order is as follows:

Intel Processor Diagnostic Tool.
Intel XTU
Aida64
X.264
ROG Realbench
OCCT
Prime95 Blend
Intel Burn Test
Two weeks of normal use with SETI@Home in the background (KWSN Lunatics AVX enhanced client).

Only then do I call it stable, and if I 0x124 or 0x101, I bump the Vcore up in 5mv increments, and reset the two week normal use timer.

Oh, and out of the box, it would be good to set Vrin to 1.900V just for good measure on Devil's Canyon for any real overclocking.

Read his first post, then you will see he can do 4.8 whit 1.22 ish volt. He is only trying to find out the 5Ghz mark. Just to have some fun, he has a very lovely chip.

Stupendous?... You need 1.4 volts for 4.8GHz?... When and what is the danger in terms of voltage to the CPU then?...
Click to expand...

More voltage you need to pump through the CPU the more of a chance you reduce the lifetime of the CPU. More volts is obviously more heat, too. Really isnt advised to put so many volts through especially 1.4V. This is why TTL did a guide on how to fully optimise your overclock and achieve the best, with the least amount of volts.

I guess the only time you would use such a high value is benchmarking, but for everyday use, the fewer the better.

1.22volts for 4.8 is damn good in my eyes.
