Core i5 2500K Questions-Weird BUS Speeds  

post #1 of 13
Thread Starter 
Hey guys, I was looking around some of my specs yesterday (mostly processor related) and I removed those Gigabyte software based overclocking tools and programs since I would only want to overclock through the BIOS, and I was also seeing how turbo boost works, and that seems to be working fine but my question is, my BUS speed is lower than it should be. I have two pictures attached of the idle speeds and full load speeds, and the BUS speed is usually at 99.8, thus reducing my CPU clock speed. How can I make it stay at a perfect 100? Sometimes when idling it goes down to 94.4 for a little bit but then goes back up. Any suggestions? Thank you! thumb.gif

I don't know about the 94.4, but 99.8MHz is perfectly normal. Mine is at that too. 00.2 MHz is really not going to do anything.

Just for the sake of it tongue.gif Couldn't use the validate button because I apparently haven't updated CPU-Z

While doing this, my Bus Speed dropped to 74.4MHz a split second, and the core speed went to 9999.8MHz biggrin.gif

Samething happens with my i7 2700K. Kinda annoying because a 45x clock doesn't give a solid 4500Mhz, but I just increased the bus speed a tiny amount to make it 100.

Do you have Spread Spectrum enabled in the BIOS? Because that can cause it to fluctuate slightly.

Not sure, where can I find that? What section in the BIOS?

Automatic settings will do that too, my FSB is set on auto and sits at 200.2 but when I set it to manual it stays exactly 200
