View Full Version : Can someone give me a quick overclocking rundown?

I've got an Abit KA7, and within it resides an Athlon 950 Classic.
Where do I start? I don't think I should up the actual clock speed (In SoftMenu III, you can change the actual clock speed in 50MHz incriments, from 500MHz up to 1GHz, or enter a user defined clock speed).
Should I up the core voltage by .5 volts, and test stability?
What about the other voltage setting, and the FSB DIP switches?
Also, is 36-38*C a normal temp for my CPU?

U could try to up the fsb in the bios in small increments and see how far it works for you. But normally a GFD would be the better choice. This will allow you to change the multiplier and the Vcore. Mine lets you change multiplier up to 10.5 and Vcore up to 2.05.
But be careful when upping Vcore, that suckers get HOT. Look for good cooling. Either Alpha or Global Win VOS 32 which is what I use. I never used the Dips, -no need.
I/O voltage may grant you some stability when overclocking your Ram, but mine doesn´t like more than 3.4. If u use PC 133 you might want to run it at the FSB+PCI setting
Hope that helps...
Feel free to ask if you need further input!

Ok, before I changed any settings from default, my idle temps were at 36-38C. I changed the Core Voltage from 1.80 to 1.85, and I got 15MHz, but my CPU temp went up to 40C. Under load, it goes up between 3 and 4C.
Right now, I'm at 1.85 core, 9.5 multiplier, 107/33MHz FSB, and my speed is 1.02Ghz. My temp is at 41C idle, 45C under load (I let Prime 95 run for about 15 minutes to test load temps).
Do these temps match up with my setup (shown in sig)? It's an Athlon Classic, so it uses .25 micron architecture, not the most heat efficient by far, but still... these temps seem rather high. (BTW, my thermistor is right next to the CPU die, between the CPU PCB and HSF.)
What are safe temps for my CPU? AMD says the CPU will keel over at 60C, so perhaps 50C would be an ideal compromize of heat for speed?
