Problems when adjusting BIOS settings for higher clock speeds
Problems when adjusting BIOS settings for higher clock speeds
I’m facing some challenges when overclocking my PC via the BIOS on my motherboard. Often, I can’t reach 144+ frames even at low settings in certain games. When I enable the "EZ Tuning/Overclock" option, my frame rates jump significantly—sometimes doubling or more—but then the system crashes after a short time or freezes completely.
I’m trying to figure out what might be going wrong. Here are the details:
My PC specs: i7-7700k, ASUS Z270 motherboard, GTX 1070 GPU, two DDR4-3000 RAM sticks.
With overclocking: stable but very low frame rates.
Without overclocking: crashes in games after 300+ frames.
The single click overclock in easy tune isn't reliable. This is likely causing your system to crash. Your temperatures might also be too high since it's drawing more voltage than needed.
Overclocking the 7700k remains straightforward. I suggest keeping the v-core below 1.35 volts and maintaining average CPU temperatures under 80°C. Restart your BIOS to factory settings, adjust the frequency multiplier to 48, which will set a 4.8ghz clock speed. Then switch the v-core to 1.3 volts and restart.
Download the hardware specifications and run Cinebench R15. If crashes occur, revert the BIOS settings and adjust the voltage to 1.31. If stability returns, monitor temperatures closely—anything above 80°C during load is a concern.
Auto tuning OC profiles aren't always reliable. You might need to boost the Vcore for stability. I favor manual overclocking over auto because it helps you understand what settings work best. Before adjusting the Vcore, it's wise to learn about overclocking properly. Avoid exceeding voltage limits for each processor and keep temperatures under control with live monitoring. Not every PSU can handle overclocking, so choose a good unit.
The auto tuning OC profiles aren't reliable. You might need to raise the Vcore for stability. Manual overclocking is usually better, helping you understand what settings work. Before changing the Vcore, study overclocking thoroughly. Avoid exceeding voltage limits and keep temperatures in check. Not every PSU supports overclocking—choose a good one.
Also, is there a more straightforward method to improve its performance? I’ve been using BIOS overclocking for a while now, but it’s starting to crash lately and I can’t rely on BIOS anymore.
The single click overclock in easy tune isn't reliable, which is causing your system to crash. Your temperatures are likely even higher than expected because it's drawing more voltage than needed.
Adjusting the 7700k is straightforward. Follow my guideline: maintain the v-core below 1.35 volts and aim for average CPU temps under 80°C. Restart your BIOS to factory settings, then set the frequency multiplier to 48 for a 4.8ghz clock speed. Next, lower the v-core to 1.3 volts and restart.
Run Cinebench R15 to check stability. If crashes occur, return to BIOS and adjust the voltage to 1.31. Monitor temperatures closely. Ensure average CPU temps stay below 80°C during load; exceeding this may harm the CPU over time.
If you reach 5ghz at 1.33 volts, it works. For more tips, check this video: https://www.youtube.com/watch?v=Qcta3RStYSM
That's really useful to know, thank you! Your concerns about the CPU are valid—running through the BIOS setup for an extended period and experiencing bluescreening could indicate a hardware issue. It's wise to investigate further.
