New to Overclocking. Need questions answered ! :)

post #1 of 4
Thread Starter 
I'm using a program to overclock my AMD Phenom II X4 955 Black Edition Stock @ 3.2Ghz. I have the CPU multiplier all the way to 16x, then as I increase my core clock ever so slowly ( 5Mhz at a time) Once I reach 225 Mhz, and I pass it, even by 1Mhz, system restarts.

The only way I can think to explain this is that I need to add Voltage. I need some backup on this since I'm still kinda new.. If it is the voltage, how much voltage should I add? Current Voltage is 1.3500

Using the AsRock Extreme Tuning Utility that came with my Motherboard.

Thanks in advance biggrin.gif

Use bios, software overclocking has never been the best choice.

As long as it stays under 55c or so, you should be good up to 1.5v...

You also need to stress test once you do an oc to make sure it's stable at that frequency, use Prime95, or Intel Burn test for this.

Alright thanks. I also recently got liquid cooling so right now its at a steady 28C at 0-5% CPU usage though.

stick to using the multi for an oc. leave the FSB alone. change your multi to 18x that will give you 3.8ghz and should be stable on stock volts (1.35) if neccesary, a bump to 1.375 may be needed. Or you can jump straight to 4ghz on a 20 multi at 1.45/1.475 volts. With a liquid cooling system, you'll still see quite cool temps.


But using the FSB to OC when you have an unlocked multi is stupid and can take longer.


So to reiterate, remove your FSB OC. The reason it would be restarting is because you've also OCed your NB and ram. Your system is unstable at stock volts.


And you dont need to stress test for that long. Minimum recommended is 1 hour. A good time is about 4 hours, or you can do 20 passes on High with Intel Burn test.
