AMD Athlon II x4 645 Overclocking Help

post #1 of 26
Thread Starter 
Hi

My freind has tried to Overclock his CPU from 3.1Ghz to 3.2Ghz by Raising the CPU Frequency after he had raised the Frequency and he pressed confirm the Computer Froze ?

I thought that it might be the Voltage so he restarted his Computer and raised the Voltage to 1.5V and then raised the CPU Frequency from 200 to 201 and his Multiplier is 15.5 but it still Froze ?

Any Ideas why ?

There's much much more to OC'ing than simply increasing the frequency and voltage. I just did my first OC today and it's apparently stable, take a look.

tell him to up the [HT REF] from 200 to 207, thats all to get from 3.1ghz to 3.2ghz, the computer froze, probably because he did something else. An increase from 200 from 207 should not make the computer freeze at all, such a small overclock. 100mhz.

Post some BIOS photos, so that we can help out more.

, oh well... probably wont be able to overclock at all.

Disable Cool'n'Quit, and C1E and any CPU SPECTRUM options.

Put the CHIPSET VOLTAGE, from 1.1v (stock) to 1.2v to see if it helps.

But if it freezes from upping the HT ref from 200 to 201, then he's out of luck.

I dont think he raised the HT he raised the CPU Frequency

So he calculated this

200 x 15.5 = 3.1Ghz

So he then did this

210 x 15.5 = 3.2Ghz

He did this in Asrock OC Tuner or something

Obviously, something is wrong if he can't overclock that chip by .1Ghz. Post the system specs so we can help.

Most people can OC that chip to 3.3Ghz on stock cooler.
