So I have a Lenovo Ideacentre k300 that has been upgraded with a radeon HD 7500 GPU, 8 GB of ddr3 1066 ram, and now I want to overclock the CPU. Problem: CPUID finds the Mainboard manufacturer as LENOVO, and the model as "to be filed by O.E.M." The BIOS has no settings useful for overclocking, and I was wondering if there were any software tools at my disposal. Any help would be useful. http://imgur.com/a/iM3gm
