Can't overclock Pentium G3258 past 3.7 GHz

It is so hard to overclock my Pentium for some reason. I set Vcore to 1.3 volts on a very light 3.8 GHz overclock in the bios and I see that the computer freezes every time to an error called WHEA_UNCORRECTABLE_ERROR. Went in the event viewer and I found out that it was an error of the CPU that happened when the frequency was changed through overclocking (error 5). So, yes, that means an unstable CPU for sure.

My system includes a Gigabyte z97x Gaming 5 motherboard, Adata XPG V1 8GB RAM 1600 MHz (tuned it down to 1333 MHz too), Pentium g3258, and a Corsair H80i (just bought that because I wanted to overclock). A Crucial MX100 SSD too. No GPU just yet. My PSU might be a bad one for overclocking, but without a GPU, an EVGA NEX750B shouldn't be that bad right???

Any ways, using software has just been a nightmare with Gigabyte's Auto Tune software which when I set to 4 GHZ overclock via performance boost, just ended up in a terribly unstable system (the CPU was apparently set to lower than 1.15 volts) and was almost impossible to reverse the effects because the overclock was on the OS. I did later set voltage to 1.33 volts to get it more stable, but it still crashed so I turned optimized defaults and that completely messed up the software (now it won't even overclock manually to my command).

I've run 4.2 GHz stable from Gigabyte Easy Tune at 1.3 volts, but that's only works when the computer is on the OS already. Always crashes during boot. Now the software doesn't work at all. Crashes on battlefield 4 as well at 4.2 GHz (yes, I have no GPU, but I'm testing). I'm also a noob when it comes to overclocking.

My last resort and most reliable way to overclock was the BIOS, but even then the CPU is so unstable (and I'm setting Vcore to over 1.3 volts!!).


Is there any way to solve these problems??? Any other settings I could change??? Or did I just get unlucky in the CPU lottery... :(

No, that CPU shouldn't probably ever need more than 1.3v for any overclock although some say up to 1.4v is ok:

I'd start over using this guide:

http://www.ukgamingcomputers.co.uk/overclocking-pentium-g3258-on-h81-b75-h87-h97-chipsets-a-60.html

Methods should be similar or even easier on Z97 chipsets. The key is to take your time starting at stock settings and use baby steps. Increase multiplier until it becomes unstable, bump voltage slightly, retest, repeat until stability can't be maintained, you reach your desired OC or the thermal limit can't be maintained.
Using the F ^%$^ing utility is what screwed things up. We tell people and we tell people not to use automatic utilities, but do they listen? Sigh. Just kidding.

Anyhow, not your fault, your didn't know right? Here's what I'd do. IF the OS isn't that old and you won't lose much, back up all your necessaries and reinstall the OS because you are unlikely to ever track down and remove all of the settings from the utility even if you uninstall it. You can try just uninstalling it but it may or may not be effective.

Next, use the BIOS only, and make sure you have the latest BIOS installed. In fact, you might just try that first. Don't trust the automatic BIOS update utility either. Do it manually. Almost every time those are used they do NOT update to the most recent version.

If you don't have the most recent BIOS, version F5, that's your trouble. You must have this version to properly support overclocking with the G3258 on that board.

These problems all happened WAAAY before I installed the utility. I installed the utility thinking it would help...but I was a bit stupid doing so. And I do have the latest BIOS.I flashed it right after I got the motherboard. I in fact started off doing some light overclocks off the stock cooler for a while and that worked for a very little while...maybe 2 or 3 days and then it started crashing. Then about 3 weeks later I tried the utility.

I think that is really the most help I can get. For now, thermal limits shouldn't be a problem with a Pentium until stuff goes beyond the 70 limit. Highest I have ever gotten was 64 degrees but that was some sort of a serious outlier. But thanks for getting me to the path I have to try on.
 
No problem. I could probably talk you through it, but it would be easier and better for you to do it yourself using the guide as you'll also learn something in the process, plus, you can make adjustments and such without having to wait for me to reply.

Oh hey after 3-4 months of a struggle I found out the problem that for some reason was hidden everywhere. My CPU Uncore Ratio was set to Auto to be set by the BIOS so I decided to leave it at 3.5 GHz and now I can run my Pentium at 4.4 GHz. Finally. Dk why I never knew this.

Just to bump this thread and confirm that I had exact same issue, couldn't get it past 3,8ghz with even borderline voltages. CPU Uncore Ratio was set to auto. Once I set that to 3,5ghz, was able to go to 4,4 area like most g3258 users.

Thanks for the solution!
