Hey Guys - First Time Poster

post #1 of 7
Thread Starter 
Hello everyone,

I've just recently started to become extremely interested in overclocking/performance boosting/modding etc and have a quick question regarding CPU overclocking. I have no experience besides very general knowledge from forum browsing and decided to do a simple overclock.

My overclock is stable? at 4.2Ghz with a Vcore of 1.24V and idle temperatures of around 37C (65C at load).


My question is what steps or programs do I follow in order to get the best possible voltage with full stability? Obviously with no experience I didn't do any testing so I'm sure I could get lower then 1.24V and most likely an even higher clock. I'm only saying its stable because I ran Prime95 for 30 minutes or so and had no problems.


Just added my own RIG for system specs.


Thanks in advance for any tips/help as I won't be back until tomorrow.

Hello and welcome to the forums smile.gif I would advise you to get a thread title that is fitting to your problem next time.

What I usually do is run Prime95 with Small FFT's for 6hours+. This usually gives a pretty good indication if it's stable or not.
I would also try your most demanding games for several hours straight and see that you get no crashes there either.
Remember to keep temperatures in check too, 70c is about max safe, but it's no worries if it goes up towards 80c really. With my setup I have around 78c on 100% load.

If I where you I would crank up that volt to around 1.35-1.37v and see how far you can go! I bet you can get somewhere between 4.4-4.7ghz depending on how good your cpu is.

What I use personally when testing if overclock is stable is as mentioned Prime95, my most demanding games, core temp and cpu-z.

Have fun overclocking smile.gif

Thank you very much for your reply. You are right, I should have used a more accurate thread title. =]

Great advice regarding the coretemp and CPU-Z program.

Even thought I didn't really mention this in the initial thread, if I want to keep my OC at 4.2Ghz (really have no need or desire to go higher) how do I get the best Vcore at that frequency? Do I just continuously lower the voltage by .005 and do a 6 hour+ Prime95 test each time I lower it until it reaches the point of freeze up?

Thanks again


I7 3930k 3.2(3.8)ghz Turbo is what I'm using.

Yeah its pretty much a trial and error thing to do it right.

My pleasure!

I would advice you to turn of turbo when overclocking if you have not done that already. Turbo can truly mess with overclocks.
What I would do to test quickly so you don't have to do 6hour runs all the time, is to just lower the vcore bigger steps and load up a game and play for a couple of minutes. Lower until you see it crashes almost immediately, and then start raising the vcore slowly up from that, still testing with a hard running game. Much much quicker to find the lowest vcore you can do then smile.gif
Then when you think you have found the stable vcore you do the prime95 tests.

Awesome guys, thanks.

Didn't actually know that turbo messed with OC's. Just looked into it and can see the problems associated with it being left on, gonna have to redo everything because i'm almost positive the 4.2ghz was being read while turbo was affecting it (BIOS shows 3.855ghz or so where as RealTemp and similar programs read 4.2ghz). Yayyyy for experimentation.

Also remember if you want the full power all the time, disable Intel Speedstep, C1E etc (You can search for down throttling cpu settings or something similar). It's usually under CPU settings in the bios. As downclocking can also make the system unstable, but can work too.
I like to have the power 100% all the time, but that's just me smile.gif
