Overclocking g3258 on MSI H81M-P33
Overclocking g3258 on MSI H81M-P33
Hello, everyone.
I came across a review about the g3258 overclocking and decided to give it a shot. I was trying to build the most affordable gaming PC possible, and I had some leftover components from my previous setup. I installed an MSI H81M-P33 board and a g3258 CPU, along with the newest BIOS version 1.7.
At first, I struggled to overclock because I didn’t know how to use the plus key on the CPU rate. The Intel Extreme Tuning Utility didn’t unlock my CPU for me either, which wasn’t too surprising. Still, when the CPU speed exceeded 3.7k Hz, my system would either fail to boot or show a BSOD.
I’m really curious about why this happened. My old PSU might be the issue, but I also think there could be a problem with my RAM. I’m eager to learn and would appreciate any advice. Thank you.
DDR Double Data Rate 667MHz is the actual frequency the memory operates at. Unless you're trying to overclock it, it shouldn't be an issue.
Power supply isn't a brand I'm familiar with, likely not ideal.
Are you adjusting any settings besides the clock speed?
As the clock increases, voltage input to the CPU and core voltage (up to about 1.3 volts) must also rise.
Using the standard cooler could cause the CPU to overheat as well.

The most recent BIOS version for that board (version 1.7) prevents the CPU multiplier from being unlocked within the BIOS settings.

Are you adjusting any settings other than the clock speed? As the clock goes up, both CPU voltage and core voltage should increase accordingly—up to about 1.3 volts.
If you're using the original cooler, the CPU might also overheat.
I only change the CPU ratio and ring ratio to the same value; should I adjust the ring ratio as well? Concerning voltage, no—I haven't changed it. So should I raise both CPU and core voltages to around 1.3V? That would be helpful, I was unsure what setting to use.
I don't think the cooler is the problem because I can boot at 3.8kHz, but then it fails the IntelBurnTest (it crashes with a BSOD during testing); however, the temperature stays below 68°C, which seems acceptable.

You just installed the newest BIOS for that board (version 1.7), but it doesn't enable CPU multiplier unlock in BIOS?
No, the BIOS does support overclocking. The Intel Extreme Tuning Utility that came with the board doesn't.
If the BIOS now supports OC'ing, you're still using the software app for this purpose. They often don't perform well. You should do your OC'ing directly in the BIOS. For now, keep all other settings at their default values and observe how far you can go with just the multiplier. Perform tests with Intel Burn Test between increases to ensure stability.
In fact, raising CPU voltages does seem to help. I haven’t completed all the tests yet, but I’m able to boot at 4 GHz now. Thanks for your advice.
Although I couldn't achieve better than 4.0 GHz due to excessive temperature, raising the core voltage to 1.280 V and the ring voltage to approximately 1.190 V still assisted in stabilizing the system at that frequency. I adjusted the CPU voltage input to 1.9 V, which appears to be the highest setting available for my board.
