MSI H81m-E34 + Pentium G3258 Locked CPU Ratio

[LilRexHD]

I've been trying to overclock my Pentium since I got it a few weeks ago and no luck, can anyone link me to a tutorial on how to do it? My problem is the CPU ratio won't move from auto, if I click on it nothing happens, If I highlight it and use + and - nothing happens... Need help ASAP

You need the most modern version of BIOS for that motherboard and if you are running Windows 10, there is an issue if you do not have the correct build.

There are also reports that MSI has recently changed BIOS on that board (and maybe others) so that overclocking no longer works. If so you may need to try an older BIOS.

It certainly used to work.

I'm on windows 7 I knew about the windows 10 thing, could the problem be my PSU? It's only 300w but I don't have anything extra installed in the PC it's just the processor, ram, and hdd, also could you link me to something that shows me how to install an older bios?

No, it's not the PSU. 300W is plenty for a G3258 and a GTX 750ti.

Let's check. What version of BIOS do you have now?

I had the latest version but recently I downgraded to I think version H.4 (that's what it's called on the website) and it unlocked the multipliers, I'm currently clocked at 4.2 Ghz, but is can you give me some tips on voltage? I had it set to 4.4 at 1.285 volts and it wasn't fully stable, it would run for long periods of time then crash, I have the ring voltage on adaptive, could that be the problem or do you think that's all my board can handle?

Good to know the old BIOS works. Thanks for sharing that.

I have two G3258s that we use at school for teaching basic overclocking. One runs at 4.2Ghz at 1.310v and the other runs at 4.5Ghz at 1.355V. That's the best speed and lowest stable voltage we have managed to get.

Neither of them are especially good chips, the first is far below average, and the second is about average.

Every chip is an individual. I'd want to know what voltage IS stable first, before I started tuning.

Our procedure is to start with brute force and ignorance, setting the multiplier and then the voltage to get it stable, and only afterwards fiddling and tuning to bring the voltage down.

So my problem was most likely not enough voltage? The temps only peaked at 70 during a burn test with AIDA 64 and under idle/basic task loads it was only around 55, and also on a cheaper motherboard like mine could that be the problem? Because I know some cheaper motherboards have problems keeping voltage canstant

 

[DonkeyOatie]

Yes. Stable voltages can be an issue with cheap motherboards and PSUs, but 1.300V is completely safe, and I'd try up to nearly 1.4V (temporarily). Temperatures need to be 80C or less.
