So since a couple of months I'm the proud owner of a AMD Phenom II X4 980 Black Edition which runs on 3.7 Ghz. Now I've asked this before on this forum at what speed this cpu could run on a stock AMD CPU Cooler and they told me 4 Ghz. Now I was wondering if someone could tell me how I shall o/c it. Would it be enough/work if I changed the multiplier instead of 18.5 to 20x and leave it at that or do I need to increase the voltage aswell?!?
Just try 20x @ 200Mhz (4.0Ghz) with stock voltage first.
This can not hurt (unless something was bad to begin with).
I think stock Vcore is like 1.36v on that processor.
You could try like 1.375v if stock doesn't hold 4.0Ghz stable.
Consider your max stressed temps before increasing the voltage more at that point.

When overclocking, you want to leave as little things left on auto as possible, because the bios will overcompensate far too much and give too much voltage, way more than is needed. Absolutely no way you need 1.47vcore for 3.7. I'd bet anything it's on auto. Switch the voltage for the vcore to manual and maybe start with 1.4v for 4GHz, and keep your temps monitored, with HWMonitor, or AMD Overdrive. Use P95, or IBT for testing heat and stability, and rinse and repeat if you need more volts, up by like 0.01v each time until stable (if your not at 1.4) Ensure your cooling policy is on active, and if you have any bios setting for min fan speed, turn it up a bit.
1.475v at stock...?
That can't be right...
How hot is that sucker during a stress test?
1.475v?? o_O whoa dude, you're nearing the limit there...
