I've purchased the CPU only a week ago along with a M5A99X R2.0 and Noctua NH-D14. I believe the CPU may have become faulty after what I believe to be a mild overclock. I had successfully overclocked it to a very stable 4.2 ghz @ 1.344v with all power saving features off, LLC to extreme, CPU/NB LLC to extreme, and both current capabilities set to 120%. I decided to overclock the CPU/NB frequency and set it to 2.4 ghz along with the HTT set to 2.4 ghz. Offset voltage was increased to 1.1875 and 1.223 respectively. Stability tests began and the system was very stable. I upped the CPU/NB frequency to 2.6 ghz and the HTT to 2.6 ghz (the maximum value) and the system would not load windows (it did post however). I reset the computer intending to up the voltages but ever since the reset the computer will not post. In fact, no signal was sent to the monitor. I reset the CMOS with the power supply off and waited 10 seconds. The bios displayed the big logo prompting me to hit F2 or DEL to enter bios. The computer does not react (usb devices are on initiated after 20 seconds), the logo disappears (text prompt does not) and for some reason the motherboard increases the speed of the PWM CPU fans incrementally the longer I leave it running. If I reset the computer at this stage the screen simply remains blank or no signal is sent at all. I have tried numerous times to reset the bios and I get the same result every time. I have reseated the cpu as well. There is no fried component smell nor are there any visible charred remains of a component. Has anyone any ideas as to what is going on and perhaps a resolution? Was I handed the runt of the CPU litter?
