OC 4790k

[ShepyT]

Hey guys just had a question for you all.

 

So I recently completed my first build and am trying to overclock my 4790k.  The issue is even at 41 for the multiplier it will run 81C under Prime95 stress tests which is not what I expected.  My cpu cooler is a Corsair H55 is that the issue?  Not adequate enough cooling?

DONT use prime95 !!!!!!!

 

Use aida64

 

As for the other part of the Q: What voltage are you running at?

Unless you are running at a fixed voltage*

Then P95 can be used as a regular stress test

That's not what people told me before. They said prime95 can cause damage to the 4790K's chipset

Heard these rumors too!

Not sure how far its true but i prefer the safe side of life.

Safe side is nice indeed. Specially when it comes to these expensive web-browsing things we have

Prime 95 increases the CPU's voltage to make sure its stable

however

on a fixed voltage that number cannot be changed.

thats why the stress test is so "intensive"

[Murdoch]

Yeah, I wouldn't use Prime 95. It made my 4790k get super hot too. The sort of hot, that simply doesn't happen in any other "full load" testing.

When I tested my overclock with prime95, the CPU wouldn't even go 100% load and on the voltage I had it set at. I then posted that here and people "shouted" at me to not use prime95 on my chipset because it can cause damage.

 

Just following the masses' opinion

Prime95 tends to make stuff a bit hot, at least for me too..  80c in prime would equal 60c in aida64.

the reason people say this is because Haswell doesn't like voltage compared to past generations, yes its a given it could potentially damage it, because of the voltage spike but the odds of that aren't extremely likely. 

Its a really common misconception, Prime95 is the worst case for workload. 

Its not that its meant to max out CPU usage 100% the real reason for P95 is for research and it doesn't want it crashing.

Its like folding but different. Either way Aida 64's the best bet for stress testing unless you really want to help Prime

I see, thanks for the explanation!

[ShepyT]

Thanks for all the feedback guys I will stress test with Aida64!

Just my two cents, but use Intel xtu. It's free forever, comes with three different stress tests, and has the best monitoring suite on the market.

And crashes a Gigabyte board if you try and use some of the controls. I'm stuck in adaptive voltage because of the XTU.

You should never use it or any other software suite to change bios settings. Lots of issues ensue (non standard sockets like gigabyte's and Asus have really really don't like being touched by xtu.) Just my two cents.

If you use it as a stress tester and monitor only then it works flawlessly.

That's why Iike Aida64, all it does it test for stability and provide information on what happening while it tests. No risk.

There is no risk for xtu if you use it for the exact same purpose as you do for aida64. I don't see how that argument is valid.

That's because there is no argument, simply offering a different preference. And a bit of a warning to anyone who uses XTU.

Hmm the warning itself is perfectly valid.

[CapricaBuccaneers]

What kind of issues are we talking about here?

I exclusively use XTU for my CPU benchmark and stress test, and I don't recall having any issues with my Asus M7G motherboard.

I have to assume it's bios related - the early revisions on my particular board weren't great in general.

With Gigabyte if you manually enter a voltage it places the voltage in static. I wanted adaptive voltage after I had found my optimal overclock. Totally ruined one of my bios and has me permanently stuck in adaptive voltage. Gigabyte motherboards are shit, my audio chip doesn't work properly ether.

Using XTU to change bios settings (AKA multiplier, bus speed, voltage) can cause major issues with non-msi and asrock mobo.
