I have a Crosshair V Formula and the first CPU I Used was the new FX 4170 4.2 Mhz. using the stock cooler, GPU is a XFX Random 5770, Power Corsair TX850, Seagate 1TB Hard Drive. RAM 2x2GB OZC Flex II air cooled. Windows 7 Ultimate 64bit. The system is installed in a NZXT Phantom 410 Case. I used the Asus AI Suite II’s Turbo V Evo just to see what kind of numbers it would pull. It jumped to 4.63 MHz and Wow, was it fast. I was very pleased, but when I tried to undo things and return to 4.2 MHz, I was unable too. I tried over and over, and even called the Asus Tech crew for help. I was told to clear the cash, but that didn’t work. After about four days the system seemed to be getting hot. At first the CPU stayed around 41.6 C and never went over 51.6 C, but it began spiking for no resin. The CPU Temp would just start climbing for no apparent reason. I would hear the fans start to rev up, and when I checked the CPU Temp would be over 54.4 C and climbing. Most of the time it would get to around 143 F and then start dropping all the way down to 41.6 C. Then it went up to 62.7 C and shut down. Then it was fine for a day. The next time it got hot it again went into thermal protect. After the second time it shut down, I pulled the CPU and put in my Phenom II 555 Black. It’s rated at a much lower wattage, but as soon as I turned it on it was also overclocked, 3.52 MHz but it’s at least staying cool (40 C) Can anyone help me reset the board so it will stop overclocking my CPU’s along with any thoughts about the FX overheating problem.
