Need help with overclocking CPU....

I am having trouble overclocking my CPU on another computer. Here are my system specs for the pc:

Motherboard: Socket 939 Biostar NF4ST-A9 with Phoniex Bios (updated)
CPU: Amd Athlon 64 x2 (dual core) 3800+ with AC Freezer 64 Pro PWN
Memory: Kingston 512mb x2 PC3200
Graphics card: Nvidia Geforce 7900 GS 256mb with AC Accelero S1 with extra fan
Power Supply: 300W

In the bios settings I just change the CPU speed to 220mhz (2.2ghz). I do not change anything else. First two tries, boots and loads into windows and then I get a blue screen. Third try, the computer doesn't boot up and then consequently I had to reset the CMOS. I am not sure what I am doing wrong whether I need to change other settings in the bios ( memory speed, memory timings , voltage). Or there is something wrong with my system specs.

I know from looking around the web this proccesor is very good at overclocking and easy to overclock without too many adjustments to the bios. e.g http://www.pcper.com/article.php?aid=192&type=expert&pid=3

I appreciate any help anybody can give.
 
My guess is your memory. If its a 1:1, your memory's going to be running at 440. Generic DDR RAM doesn't always clock that well.
 
It's been a year since I was on the AMD side of things, but off the top of my head:

1. Make sure you are adjusting your HTT multiplier to correspond with your overclock. You don't want your HTT speed to be over 1,000mhz. So assuming you want to run at 220mhz FSB, you need to change your HTT multiplier to 4x (4x220mhz = 880mhz HTT). You ahouls have an HTT setting in your BIOS to adjust this, it will either be labeled 'HTT Multiplier' with values like 1x, 2x, 3x, 4x, 5x or it will be labeled 'HTT speed' and will say 200mhz, 400mhz, 600mhz, 800mhz, 1000mhz.

2. You may need to bump your CPU core voltage a notch or two to attain stability. You may also need to adjust your memory voltage and/or chipset voltage.

3. Make sure you're not running your memory at out of spec speed by raising the FSB.
