: Hi, I had an AMD K6-2 500Mhz CPU, and I wonder what should I do to overclock it to 550 or 600, do I have to turn the 2.2v to something else? and do I have to turn the X5 to X5.5 or X6.0? Because last time, when I overclock to 525, it works, and when I tried to overclock it to 550, I turn the jumper but somehow it didn't work, all black(I didn't turn the SW for it, and I wonder if I have to turn the SW to do the thing.)
: thank you.

Speed you can get depends on Front Side Bus (memory) speed, memory rating and quality, CPU multipliers available, Power Supply quality, voltage regulator capacity, CPU cooling and MORE.

You may find some variability between "identical" boards - some may do better than others, but generally, you need FSB speed of 100 MHz and multiplier of 5.5 to get 550. Most Socket 7 and SS7 boards have multipliers up to 5.5x maximum. Get higher speed with higher FSB speed. AMD trained the high speed K6-2/K6-3 series to recognize multiplier of 2x as 6x so you can get 600 MHz by using 2x and FSB 100 MHz. You also MUST have memory rated for the speed (good quality PC100 minimum). Power supply and regulators must provide the power and the voltage regulation. Check the mainboard maker's specs - sometimes more recent revs have necessary features that earlier ones don't have such as voltage settings, voltage regulator quality and multipliers. Power supply should be AMD approved - drill down and find AMD power supply requirements at:
http://www.amd.com

Actual, measured core voltage may be lower or higher than the settimg; check actual core voltage with a good digital multimeter. Figure out where from the mainboard manual and chip pinouts. Some FSB speeds are stable with some CPUs, unstable with others

Search the internet for "overclock" and "overclocker"; there are a lot of people into overclocking - and they share info that can help just get the thing going at all.

Good Luck,
Henry
