Is 4ghz possible on a 740BE?

post #1 of 32
Thread Starter 
I'm new to overclocking and am looking for some guidance. I would like to push my 740 as high as I can safely, but do not really know how to do so. I am aware that since I have a BE chip I can simply raise the multi, but my question is what about voltage, ram/ram timings, and anything else that I might be missing. When/how do I change them if need be? Here is the links to my mobo, ram, and cpu. Sorry for all the noob questions, and I really appreciate your help.

Probably, I have mine at 3.6GHz unlocked at 1.45v

Depends on the chip, though

The rest of the stuff doesn't matter much, play around with the FSB and multipliers until you get it stable. vCore max is 1.55v probably. You can try cranking up the CPU-northbridge too.

You could try looking up some review's of the chip? it would give you a rough idea of a "Safe-Overclock" for your type of cpu is

Hope this help's (Google is your best friend )

Its a c2 revision, so 3.7-3.8 most likely, maybe 4.0ghz but with really high voltage.

On custom water, it might be possible. On the h50 you've got, not likely.

I'm hoping to get 4.0ghz out of my ol' 720, but I kind of doubt it. It needs ~1.5v on air for 3.6ghz when unlocked to a quad.

this pretty much sums up the cpu pretty good. I honestly doubt u will even get 3.8 to be honest... It's still a good cpu though. Especially if it unlocks since it's a great value.

Should I leave my voltage on auto, or should I mess with it when I start my oc? I'm guessing 1.5v is the highest it can go before I have to start worrying about frying something.

Safe max volts would be 1.55v, but you won't have to worry about something frying at those volts, you just have to worry about the temps at those volts. Keep your temps below 60c at full load and you should be fine. You won't start frying things until you hit 1.6-1.7v, on air cooling and units like your h50 that is.
