Can I get to 4.0GHz on a 965 BE?

post #1 of 36
Thread Starter 
I can do 3.6GHz just fine but I have never went over because I don't know anything about increasing voltage. How do you tell if a CPU is unstable or not and you need to increase voltage?

Also, what will it say on Prime95 if the CPU becomes unstable? How long should I test the CPU before I know I am ready to overclock farther?

I really want to only go up to 4.0.

You will know you need to increase voltage when you recieve a BSOD when stress testing.

Isn't it kind of bad to get a BSOD? Will it harm any components?

Also, what is the max safe voltage I can get to and what interval should I increase voltage by?

Do you know if you have the c2 or c3? I'm sure the C3 ones can hit 4GHz easily.

As long as you dont go over 1.6v or 1.55v as most say, you will be fine. You should try LinX for 5 runs, max memory usage and it will be a quick easy way to tell if you're stable or not.

And be sure to have your temps below 55c.

Happy Overclocking!

It's not bad if you keep BSOD, only your hard drive might get messed up.

I have herd that 4 hours is the norm for prime but I use Intel Burn Test I have been told that it is much better.

I have my CPU at 1.488 Volts.I have been told not do go over 1.50 volts so start with small increases in voltages.

Follow this guide, it's pretty helpful for new amd overclockers

http://www.overclock.net/amd-general...ing-guide.html

You may not be able to hit 4ghz with a phenom II but the C3s are a lot more likely to hit 4ghz. Prime is not very specific on what need to be done to achieve stability. It takes some time and patience to get to your desired overclock.

Just remember, when raising the fsb, you may need to increase the dram voltage to get your system stable. Feel free to pm me if you need any help.

Edit: You should run prime95 for at least 8hrs.

BSoD will not harm your components. The BSoD in itself is just an error from one or more components in an overclocked system being unstable.

There's more to just upping voltage though for a successful overclock.

Check around, there's bound to be some guides somewhere on here.

Good luck.

How do I check whether my chip is C3 or not?

Cpu-z will tell you under the revision section. If you recently bought it, it's gonna be a c3.
