Does reducing the CPU voltage increase responsiveness?

After failing to OC my FX6300 I decided to use the 'Fail-Safe' pre-configuration in the BIOS. I also reduced the core voltage down to 1.15V and it seems like the PC is more responsive now.

Is this true in any way? If not, what could be happening in my case?

Hello... Scientifically you have reduced heat and current flow to the CPU... while doing the same JOB...and Yes...MB defaults CPU voltages are too high (safe setting) for Todays typical Semi-conductor Quality material we are seeing in CPU products... Some people get the "Golden ticket" in the materials... and that your CPU was made from... Experiment in the BIO's and manually find the "minimum" voltage needed, if ya like too B )

Hi,
If the PC is actually more responsiveness this suggest that:

1) the BIOS on boot detected an issue and set to defaults (unlikely as it should tell you), or

2) system is slightly unstable with the OC. Not enough to crash, but possibly enough to corrupt some data etc

Other:
Voltage dropping?
If your overclock was unstable, then dropping voltage would likely not help. We usually RAISE the voltage to help stabilize a frequency that is high enough that the leakage needs to be compensated for.

Since you did TWO things at the same time, I'd say it's simply a result of you setting the "fail safe" (default) settings.

Other:
If you want to overclock, then go ahead but this time read a guide or two if you have not and run tests like Prime95 whilst monitoring the temperatures to ensure stability.

HANDBRAKE would be more realistic to a common worst-place scenario. You could start converting a video while monitoring in Task Manager (make sure CPU->performance is near 100%) then monitor the core temps in the program "core temp".

I believe that over 70degC for that CPU is considered overheating. If it does you could look for a better cooler. If you have stock then a Cryorig H7 would be better (setup a proper fan profile with motherboard software regardless of cooler... unless it's a liquid cooler with its own control).
