Changing CPU speed is causing me a lot of trouble!
Hi Folks,
I just completed my new rig and thought you might have some tips on overclocking.
Asus P8Z77-V
8 gig Corsair vengeance 1600mhz
i5-3570K
I’m facing some problems (probably) with power-saving settings. I attempted the auto overclock tuner, but after rebooting, the post screen always displays the default CPU speed without showing the new frequency. I also went into BIOS (a bit reluctantly), set the CPU ratio to manual and entered 44, then adjusted BLCK to 100, but the frequency in Windows 7 (64bit) keeps fluctuating wildly.
I’m reviewing details with 'cpuz' and 'real temp', but it doesn’t stay at a consistent 4.4MHz. I disabled what I thought were power-saving features in BIOS, but they’re still changing.
I also tried setting the vcore voltage to 1.25, but the PC would keep shutting down and restarting repeatedly until it seemed like the right voltage was applied. This constant cycling makes me anxious—especially since this is my first experience with the new BIOS. I just need a stable overclock for testing under stress.
Any advice would be greatly appreciated.
P.S. Is it okay to overclock the CPU while keeping RAM at 1600?
In ai tweaker, there are settings for long duration power limits, long duration maintained, etc. Put those up. None of the power saving options impact this, so you should enable speedstep and c states if they were disabled. You can adjust the RAM speed as desired—it doesn't significantly change performance.
Even though the vcore was altered, cpuz now claims the vcore is 0.92v. It seems like power-saving mode is working. Do you agree? For it to continue changing. Also, I adjusted the BCLK to 100 and now the ASUS software is reverting it back to 102. Why does the motherboard keep resetting its settings? Shouldn’t 100 x 44 justify a rollback? The core speed and multiplier are fluctuating—x16 then x41, etc. If someone could share the UEFI settings, I’d be willing to experiment. I’m uncertain what to do. This new BIOS is quite unfamiliar, and it took me a while to figure out how to enter the settings. I was expecting a drop-down menu of frequencies.
You're referring to going down to 1.6ghz. It doesn't really impact performance, right? Unless you're already at maximum capacity and it starts dropping, then that becomes a concern. You can try setting the power settings to minimum 100% in Windows to keep clocks stable. The OC software might interfere with the BIOS, but it's better to avoid using or uninstalling it altogether.

You really should read more guides before overclocking. All your points are normal. You shouldn’t rely on auto-overclocking either; manufacturers often overvolt CPUs at any clock speed.
Don't worry.
When the CPU has little load, speedstep or EIST lowers the multiplier to 16.
That's typical. It conserves energy without impacting performance.
If you force the CPU to maximum capacity, such as with prime95, it will stabilize at 41, your overclock setting.
I appreciate all the responses you received. Thank you very much for taking the time to reply. My main goal is simply to overclock and maintain consistent performance. The problem I face is that when others adjust their settings using this motherboard, I often overlook details like mine (unstable frequency changes). Shouldn’t adjusting similar BIOS settings give me a comparable outcome?
I know each CPU behaves differently, so the final overclock results will vary... but I’m specifically interested in stable frequency adjustments.
I understand that each processor is unique, and the overclocking results will differ. However, I’m curious about setting frequencies manually and seeing if similar issues arise with other users using identical hardware.
I’ve learned that OC settings aren’t displayed on the chip itself—so a 3.5MHz chip won’t show the overclock value (only AMD seems to do this). I just need a reliable overclock.
Someone mentioned using Windows 7 to preserve settings, but I tried it and don’t understand what they meant.
I tend to enjoy seeing the actual OC numbers, knowing it confirms the overclock. With AMD, the overclock appears when you right-click ‘my computer’ in Windows 7. With Intel, it doesn’t seem the same. All these changing frequencies might not be significant for professionals, but for someone like me, I’m unsure whether a game running at 4.4GHz is actually faster than a lower frequency (as it keeps shifting). There’s no clear way to know your gaming speed just by playing.
Very frustrated!!
In reply to GEOFELT,... welcome and thanks for your helpful suggestions. The issue I face is that I set the CPU to 4.4, but in Win 7 the utilities display 4.1. It seems like the motherboard is altering things. When trying to copy settings from sites like YouTube, I create a list of the settings they provide, but some are missing, leading me to believe my BIOS version differs from theirs. This isn't resolving the problem.
In simple terms... people with the same setup don’t complain about roaming CPU speeds because they just want to set a speed and keep it steady until they change it. It’s normal for these boards to restart after a reboot or BIOS update, sometimes pausing briefly before resuming—this can be confusing but usually harmless. Just relax and put this worry aside.
