Hi guys, I've been trying to overclockers my cpu for the last couple of days but I'm struggling quite a bit. I'm new to this sort of thing.
I bought the above setup about 3 years ago and managed to clock the cpu to 3.6 without adjusting the voltage. I can't remember exactly how I did that.
But now I'm trying to overclockers it to about 4.0 before I upgrade my gpu and ram. But each time I restart PC after setting it in the bios and running prime95 and coretemp, it tells me that my cpu is still at 3.6... it doesn't seem to be changing it at all.
Ive tried upping the Vcore also... nothing seems to be sticking when I run the stress tests, but when I go back in to bios it's shows that I have changed the clock to 4.0... Any ideas?

Just to clarify have you set the cpu clock ratio to 40 ?

Yes.

I'm guessing you don't get an overclocking failed message when you save and restart as you haven't mentioned it.

Can't tell you why it's happening, only what I'd do (someone else may have a better clue). I would load up the Default BIOS settings, save and exit, and then attempt to set your 4.0GHz OC again. If you want to try leaving Vcore on auto, then go up in stages, 3.7GHz, 3.8GHz...

I've already reset to default settings and tried it that way. stil doing same ****e though. Ill try the last thing you said.

Alright. Then next step would be clearing the CMOS. This is from your motherboard manual:



To be thorough you'd have to try all three if necessary, otherwise it can't be eliminated as the issue.

Question: do you have any overclocking software from Gigabyte within Windows? Like EasyTune 6? If so, uninstall that.

Now that you mention it, I did have some Gigabyte software at some point. I think I used it to try to OC my GPU, but the voltage is locked on it.
I may have messed about with the CPU on it also.
But I'm pretty sure that was before I had my SSD, I've had a clean install of windows since then. No sign of any Gigabyte software.

Ok... I just noticed something really strange.

I just loaded default setting again. So it should be back on 3.4 and it's showing as tha in bios, but it's STILL showing in cpu-z as 3.6
Something is jamming it at that speed or what???

Ok i just did mine and mine is showing 4ghz

Try this before clearing the cmos, set the cpu clock back to 34 then go into advanced cpu core features. Set the intel turbo boost to 40 for all 4 cores , save and reboot.

Ok, just tried that. Still showing as 3.6
I also tried with the Turbo Boost Technology on both Auto and Enabled.
 
Surely there is something causing it to be stuck at 3.60Ghz?
I remember trying to OC the CPU 3 years ago after putting this rig together. I didn't play about with the voltage as I was a bit nervous doing it for the first time unsupervised, But I'm sure I managed to get it up to an unstable 4.2, then knocked it down to a stable 4.0. If i'm remembering correctly.
The CPU was changing as it was supposed to according to the monitoring program. But for some reason it's just not doing it now...

Ok.... so I cmos'd the mobo and then loaded default settings in bios and changed the clock speed to 40 and the intel turbo boost to 40 on all 4 cores.

The VCore is still on auto.
I'll be happy with a steady 4.20Ghz speed unless a little higher is easily achievable without making it burn out? Will I need to change the voltage for that?
I'm stressing the CPU at the moment and the temps have gone to 62-68degrees and its been running for about 10 mins now on full load. How much is too much on the temp?

I don't know about Prime. Cinebench max temp of 70C is a good marker for me. There are a few things that will make it run about 5 degrees hotter than that (H.264 encoding etc), and 75C is about what you want as max for regular use.

Every chip differs so you'll have to find out if you'll need more Vcore or not. If you do, adjust Vcore in +0.025 increments. Cinebench is a fast bench so it's useful for a preliminary feel of an overclock. i.e. If it keeps passing Cinebench, keep increasing the overclock. Once it fails, dial it back 0.1GHz, and test with other stuff. Prime if you want. Asus Realbench is good.

Ok, so I've left the Vcore at auto (don't know if that's a good thing or a bad thing)
I've just set the cpu to 4.40Ghz and it ran Cinebench with no problems. However, when I ran Prime95 the temps rapidly went up to 80degrees within 15 seconds so I stopped it.

I'll try it at 4.20Ghz and maybe stop being greedy ;)
 
Just tried it at 4.20Ghz, only for about 15 mins as I want to go to bed soon... but the temps hit a max of 75 degrees.
Is that too high?

If I start playing around with the VCore, is it possible to reduce the temps while still running at 4.2Ghz?

Auto volts will often pump way more voltage than necessary :)

I've been messing around with the voltage since my last post.
Tried 4.2Ghz with 1.1V and pc crashed after 2 mins in to stress test.

I've now got it running at 4.2Ghz with 1.125V. Max temp is 71 degrees after a 30 minute Prime95 max load stress test, but it's averaging about 68 degrees.
The cores are idling between 25-30 degrees.

Are those temps high enough? Or would you stretch for 4.4Ghz?

What temp you getting with Cinebench? You can't find a regular voltage/temp based on Prime. Too hot (depending on which test). It's an exception. That's why I don't bother with it. Cinebench/Asus Realbench/H.264 encoding, those will tell you how hot at max your CPU will be gaming etc.

Wouldn't that depend on what type of games you play?

I just ran it with Cinebench and got max temps of 50 degrees.
