Hello everyone!
My PC setup looks like this:
i5 4690k @4.5ghz, stable at 100% with no issues, it handles up to 60%.
GTX 1070, 16gb RAM, 1.6mhz clock.
I use the Gigabyte Z87X-OC Force motherboard.
The system runs very smoothly, but I’m still puzzled by a minor issue that keeps appearing.
I’ve set the overclock to 4.5ghz, but HWmonitor shows values between 4.466ghz and 4.566ghz under heavy load.
Could this indicate a problem with the overclock? Am I actually losing performance because of these small changes?
Even when I turn off all power-saving features, the fluctuation remains.
Please advise and thank you!
your multiplier remains consistent; it's just the bus speed that fluctuates slightly. Therefore, in an ideal scenario your 4.5Ghz should be around 45 x 100, but in reality it varies between 45 x 101.46 and 45 x 99.24, which is completely normal.
Download cpuz and observe the bottom left corner of the window—you'll notice the bus speed shifting. I currently have an i7 2600k running at its default speed, and both the multiplier and bus speed are changing continuously. The multiplier reaches a peak of 38 and drops to 16, while the bus speed stays near 100.9, fluctuating between 99.8 and 101.46.
100C are brave individuals.
Have you experimented with adjusting the clock speed, such as 43x? Does it remain stable at 4300 or does it fluctuate significantly?
Have you modified any other settings? If not, consider resetting the BIOS to default and retrying the overclock.
MeanMachine41 :
If the temperatures are between 60-65C under load, you're safe and those small frequency changes are normal too.
Could you explain what might be causing the jump of 100 MHz? I've never seen it before, so I might need to understand better.
Thank you for the update. I experimented with settings 4.2, 4.3, and 4.4. Resetting to the default and starting fresh still results in the same fluctuations. On my end, I clarified that at 100% it meant 100% XD. It works very well, with no errors or blue screens. I’m curious if this might be affecting performance. Thanks all!

Download the cpuz and observe the bottom left corner of the window—you'll notice the bus speed shifting. I'm using an i7 2600k at work right now, running at its default speed. The multiplier and bus speed are constantly changing. The multiplier reaches a peak of 38 and drops to 16, while the bus speed stays near 100.9, fluctuating between 99.8 and 101.46.
I wasn't aware of this bus behavior before. Thanks a lot for your time and understanding.
Best regards
