CPU: i5-4670K
GPU: Gigabyte GTX 1060 3GB
OS: Windows 10 64-bit
RAM: 8GB DDR3 1600MHZ
MOBO: MSI H81M-E33 (MS-7817)

At first, I purchased the H81M-E33 with overclocking in mind and always pay close attention to my parts. However, it turns out this specific motherboard isn’t designed for overclocking, which is what they claim. Despite that, I quickly realized I couldn’t overclock my CPU. I ended up installing an aftermarket cooler to try and achieve the desired boost.

The issue became clear: even though I searched thoroughly and found no signs of overclocking capability on this board (except when paired with the G3258), I still hoped for success. After adjusting the BIOS settings, I managed to push the CPU to 4Ghz, but it only changed the CPU ratio—not the actual clock speed. I was thrilled because it helped me stress-test and kept temperatures below 70°C consistently.

But now I’m frustrated. After all the work on the motherboard, I turned it off for a break and came back the next day. Unfortunately, the PC wouldn’t overclock again. I can still adjust the CPU ratio as before, but even at a lower clock speed (like 3.3Ghz), it remains stuck at stock performance. When I check the CPU Ratio multiplier, it shows whatever number I entered during the previous boot—whether 33, 36, 40, or 42.

So, why can’t I overclock now if I managed to do so yesterday?

Note: Before attempting overclocking, I followed several recommendations from other boards (like removing the CMOS battery for a few minutes, updating BIOS to version 6.7, changing settings to 'Optimized Defaults' and restarting). I also initially underclocked the CPU to see if it would affect the ratio—though it did change.

There is a locked BIOS overclocking technique you could attempt. You can find more details here: https://www.techpowerup.com/forums/threa...cs.235975/ The adjustments required may also be found in Windows settings.
