First time overclock

hi so i have a AMD FX6300 and an ASROCK 990FX EXTREME 3 mobo i know how to get to the bios but what would be a safe overclock with a stock fan going to get an after market one soon and would it be worth it to overclock it at this stage.

Don't overclock with the stock heatsink/fan.  The stock AMD hs/f is terrible, and can barely cool CPUs at stock speeds.

Not worth it on stock, you'll have a bad time.  Put a CM hyper 212 evo on there and then go at it.

according to Core Temp im running at MIN 11 degrees and MAX 21 degrees

Don't use a stock cooler for overclocking. Especially an AMD stock cooler 0.0

I mean, you could probably hit....4.1ghz on all cores more consistently than with turbo...at stock volts... but I doubt you could push it further

What are you using to monitor, because a lot of the time AMD's core temperature monitor is not good at lower temps, and is not a good judge for them.
