Hi Guys.
I have motherboard Gigabyte 970a-UD3 and cpu AMD Athlon II X4 645.
My problem is that in the BIOS the cpu clock ratio is at 15.50. I can go only down but not above.
minimum 4.00 maximum 15.50
Any solution for this ?
Thank you and sorry for my english :)

The clock speed of a CPU is determined by the base clock x the multiplier. Since your multi is locked, you have to increase the base clock. But be aware that other stuff runs off the base clock speed as well. RAM, H-T buss, etc. I doubt you'll get much more than a couple hundred Mhz more than stock with the Athlon II X4. Most weren't great OC'ers. You will need more than the stock cooler to get very far anyway. Google "overclocking the athlon ii x4 645"for more tips.
