I have an AMD A8-7600 APU. Why does my pc freeze up completely after i overclock it to 3.5 periodically? it was alot more frequent when i first started overclocking. Then i revert back to stock for a couple of days after it happens, but now it runs pretty good this is the third day at 1866 Mhz memory. i was overclocking the ddr3 to either 2400 or 2133 mhz when i first started but i just don`t know how to put in the numbers higher in manual on my ASUS A88x-plus bios Ai tweaker when i enter it. It automatically reverts back to 3.5 i can`t get to 3.8 is there a link anyone has that i could learn more about this?thank you for listening. Tim W.
