4790k Overclocking (help)

[Gavin Gilchrist]

hello  there im currently in the process of trying to get the most out of my i7 4790k i cant tell if i just got a bad pick or its another component that is causing instability making it bluescreens i am able to run more than stable at 4.6ghz @1.275v with no problems i tried to push it up to 4.7ghz @ 1.285v and after 10-12 mins on aida is blue screened the tempatures were max at 69c-70c as i am using a dark rock pro 3 so i know that was not the problem i know it was not my psu as i have a corsair rm650x  is it possible that its my mobo (asus z87-a) stopping me from achieving higher results ive looked at other people results and they can push alot less volts into there cpu without any problems and still get higher clock speeds should i just go to 1.3v and try get to most out of that or should i just stick with what i got 

 

thank you

I'd say 4.6 - 4.7 is bloody good 

 

I get 4.4 with my 212 evo

I'd just stay there. I don't think it's worth it for the performance you get out of an extra .1 at those temps.
But, I also don't have the money to drop on more parts, so there is that, too.

Don't be too afraid to push it a little . You can probably run that processor at 90C and it wouldn't skip at beat. Just push it a bit. I wouldn't recommend running it at more than 80C for your final overclock though.

i was running that on my old cooler but choose to get an upgrade what Voltage are u running at to get those speed

my line is about 85c and i was only ast 80% cpu fan at 70c but its going above that 1.3 volts i dont feel safe going above it as people say not to

yeah I can hit 4.8ghz on a 1.310v overclock but if I were you I would try going to 1.29 volts and if it doesn't go any higher then don't try anything higher

There are two 4790Ks in our house, one gets to 4.8 GHz at 1.3 v the other requires 1.32 volts to be stable at the same clock.

 

IMO 4.6-4.8 GHz at anything below 1.3 v is a pretty decent (but not spectacular) chip.

ok thx i tried getting 4.7ghz @1.295v but got a blue screen so im not feeling to excited atm

Try 1.3.  Personally I don't think 1.32 is all that bad, I just wouldn't run it 24/7.

[Advic3]

I got 4.6 @ 1.35

[jjohnthedon1]

I get 4.7 at 1.287

[Advic3]

I just got 4.6 @ 1.29

[Gavin Gilchrist]

right emmm soooo i can push 4.6@1.275V but bluescreen after 3 mins soon as i try 4.7@ 1.3v the error i always revive is whea_uncorrectable_error any idea on why this is happening because im assuming its wanting more power

It is wanting lower temperatures most likely, it scales much better with lower temps.

The relationship between clock speed and voltage is exponentially growing. 

 

Up the voltage until it's stable or the temperatures are too high. If you can't get it stable, then the silicon lottery is not in your favor. If the temperatures are too high, then you need better cooling and you still might not get it.

 still not stable at 4.7ghz @1.312v and thats maxing out my cooler and temps at 75c so i guess im just not getting it
