Help with OC

[A Silver]

I know the answer is probably yes but i have a hyper 212 evo and i tried overclocking my i7 4790k to 4.5ghz but every so often i would get a bsod and sometimes it wouldn't even boot. If i added another fan to my cpu cooler would it make the OC more stable or am i better off getting an AIO even though it costs more than i am willing so spend at the moment.

Well the lower the temps the better electrical conductivity there is. What voltage are you using?

I didn't change it so stock voltage

Adding another fan won't help much, you'd most likely need a better cooler all together.

Or you could have bad silicon lottery and 4.5 is your max.

 

You'd most likely need to up the voltage too, normally can't push too far on stock voltages.

Cooling VRMS can make an OC more stable. 

 

The CPU being at 50C or 80C won't make any difference (as long as you're in acceptable margins). 

 

Obviously, if you are making up the temperature difference by decreasing voltage, then yes - but that's a double edged sword.

What's stock voltage? On most CPU's it is pretty hard to hit 4.5 GHz @ stock but considering the boost clock of the 4790K is 4.4 GHz... That's not on all cores though.

defo on an 8350, my VRMS heat up greatly when overclocked. I really need to try get a fan on mine.

[OwensWorld]

It will depend if temperatures get too high, if you have any thermal throttle feature enabled on your mobo. If temperature becomes to high your mobo will want to reduce CPU voltage which effects all other components, The fan you have right now is good but water cooling can make a difference.

what PSU do you have? 

 

Sounds like you need to bump the voltage (monitor temps) to get it more stable. It also sounds like you might actually have a power delivery issue. 

[Ryujin2003]

Unless your system is crashing specifically due to CPU temps, I would say you probably need to work on some voltages. You can only get so high on stock voltage before your system becomes unstable. Have you tested on Prime95 to see if your CPU stops working properly? Once you get a rounding error, you know you need to adjust your clock and/or voltage.

 

Again, I'm definitely not an expert on OC. I mean, I've been stuck at 4.5 for a while, haven't got 4.6 solid on my CPU yet. However, I do know that the information you provided isn't enough to determine either way (heat vs voltage issue). You BSOD, what is the BSOD dump file? Check event viewer and see what the issue is. Test on Prime95 and monitor temps. etc... This information will help in providing information. But if you are at stock voltage, you probably aren't exceeding heat issues with your heatsink, so I'm guessing voltage, but again. Not an expert.

 

Provide some additional information please.

The temps did stay below 90 during a stress test so it does seem like it was a voltage issue. When i try again ill bump the voltage up.

Just bump it up slightly and try to see if you can get 4.6 or even stay stable at 4.5. If it doesn't, you've reached the limit of the silicon lottery and there's nothing you can really do about that unfortunately.

I was planning on overclocking my CPU but after doing a 10 minute prime95 stress test i don't know if i should overclock. Should i hold off overclocking until i get an extra fan for my cpu cooler or is it safe? It peaked at 92C but then went down to 70C after that and it stays around 40C when idle (or as idle as you can get with windows 10)

 

 

[bgibbz]

yes those are easily safe. As long as you are below 85-90 you should be good.

 

 

edit- read the wrong coloumn. Those are right at the high end. it should be good during everyday use but you should upgrade the cooler.

[paddy-stone]

what's your vcore? but yes those are safe temps, the CPU doesn't even thermal throttle until 100c, but I suspect that prime95 might be the problem here and showing too high temps. Try a newer version of prime95 or even better get AIDA64 and test with that.

Be weary of doing Prime95 on a Haswell based processor, I was informed not too long ago that it can give you unrealistic temperatures because of how the program stresses the chip. In other words it doesn't do a very efficient job and can give wildly high temps. I'd get your hands on Aida64 if you can, it's free for the first 30 days and does a much better job.

 

To your overall question as to whether or not to overclock your CPU, I've found it's pretty pointless overall. I own that processor and it's a beast just at stock, and none of my games are really CPU bound so to overclock it is just stressing the chip for little to no gains in what I'm doing with it. Of course your mileage may vary and your needs different then mine, but it's a ballin' chip even at stock.

What benchmark should i run on Aida64 as there are lots of different ones

Run a system stability test and just have the CPU box checked, that way it'll just stress that one chip. I usually leave mine for 6-12 hours to ensure stability, but it's up to you. Later I'd do a whole system test just to make sure your rig is solid.

I am trying to overclock my i7 4790k but i have no idea what to change the voltage to or how. I have an MSI 795 Gaming 5 motherboard and there are a lot of voltage options in the BIOS and the core voltage is greyed out and i can't adjust it. Any help is welcome.

Did you mean MSI Z97 Gaming 5?

 

You really should take the time to learn the basics of overclocking before jumping into having someone tell you what to change otherwise if problems arise from your overclock, you'll have no idea how to address them.  Not to mention that you don't want to assume that the person that's helping you knows what the hell it is that they're talking about.  There are tons of "how to's" on YouTube and you may even find something specific to MSI BIOS configurations.

 

Also, run through your manual in order to become familiar with your BIOS layout and what each setting does.  Tie that in with the basic information you learn through your basic overclocking research and you'll have more than enough to get started.

 

If the motherboard I listed is correct, I have attached your manual in PDF format.  Also, here's a basic overclocking video from JayzTwoCents.  There are tons of them out there.

In AIDA64, run CPU, FPU and cache checked, otherwise you are going to get unrealistically low temps.

 

RealBench 2.44 is a good test to run as well.
