I was attemping to unlock the 4th core on my amd x3 455 utilizing an msi 870-g45 motherboard. After first try I found that it is unstable I attempted marginally increasing power to the CPU. I increased it originally to 1.35 volts as well as it appeared a bit more secure so I attempted 1.43ish. I as well increased the cpu-nb voltage to 1.4.The PC no longer posts I have make an effort for resetting the cmos both along with jumpers as well as by pulling the battery. The problem is, is there a way to solve this.
