How to overclock a AMD athlon II x2 240 series

post #1 of 5
Thread Starter 
I am new to the whole overclocking thing and I am wondering what would be the best way to overclock my cpu. I heard that that the Athlon II x2 240 is a good cpu to overclock. Any ones help would be greatly appreciated.

First don't overclock using software. Do it via BIOS. Secondly it's not a BE chip so you won't have the multiplier to play around with.

Second, do you have an aftermarket HSF? I highly suggest one if you're going to go anywhere beyond a "mild" overclock.

Third, basically all you need to do is raise the FSB frequency. So when you startup press the button to enter BIOS (usually one of: Del, F1, F2, Esc, Ins, or some weird combination like Ctrl+Alt+Esc). Once you're in there should be something that says something along the lines of "Jumper Free Config", get in there and raise your FSB (should be at 200 stock). How much to raise it by? I don't know but right off the bat I'd be comfortable with going up to 215. Test that in your OS to make sure it's stable.

One more thing, it's ideal to try and keep your memory divider (RAM:FSB Ratio) at 1:1.

Also it's best to consult a guide on OC'ing. Even I consult guides when attempting extreme OC's and make sure I'm not doing any harm to my system. However I do know enough to do a mild OC (it just takes practise).

What you mean by HSF?

HSF = Heat Sink Fan

They come in 2 flavours basically. Stock OEM coolers ie: http://techreport.com/r.x/2009_4_14_...tock01-600.jpg

or "Aftermarket" like Cooler Master, Scythe, Zalman, Arctic Cooling, Noctua etc. (ie. This beastly Noctua D14 or this Ninja3)

If you're not looking to spend that much I highly recommend the CoolerMaster Hyper 212+ it's a pretty good cooler for what you're paying for. Otherwise my other favourite right now is the Scythe Ninja3 in a 2 fan push-pull config (one fan pushing air into the cooler and the other fan pulling it out and exhausting it to wherever).

Also, it might be worth it to take a look at this thread to see what the 240 is capable of achieving (YMMV although I'd probably say it's probably not a good idea to go past 3.4 Ghz) http://www.overclock.net/amd-cpus/56...-x2-240-a.html

Don't try to go up that high though, and it's probably best not to mess with voltages when you're a newbie to OC'ing because it can really damage your expensive parts (ie. DFI mobo's which are like "yeah we'll totally let you run your mobo at crazy voltages that will instantly set fire to your $2000 worth of parts"....)
