I have an AMD FX 8320 at 4Ghz on stock voltages with 20x multiplier on an ASRock Fatality 990 FX Killer Motherboard and Hyper 212 Cooler. My load temp is 68c. I want to OC it further. How far can I take it with my cooler ? How far in stock voltage itself ? Can I take to 4.4 Ghz ? If yes what voltage increase ? Also is increasing multiplier enough or change FSB but changing FSB caused me some trouble. And when increasing multiplier with all power savings off my maximum cpu speed while gaming in Task Manager is 3.96 Ghz and with power savings on I get only 3.92 Ghz. Why would is it not attaining complete 4 Ghz ? Also on keeping power savings settings off CPU speed would always be 3.96 itself regardless of what is running. But on keeping them on my CPU speed shuffles like usual at stock speeds. I want it to reduce and increase when required and is there any problem in keeping power savings settings on when Overclocking. I have a GTX 760 and 650 watts PSU. Sorry for the long post and Thanks.
