Are you sure though that your 2100 is running at 166? This is definitely not normal, I am pretty sure there were no 2100's released that ran at 166.
More likely you're running the 2100 at 133/266, which means that if you upgrade to a barton mobile, you need to make sure that your motherboard can handle the 166/333 frequency most bartons run at (a few run at 200/400). You'll also have to upgrade your ram.
I'm sorry, I'm a moron... My chip is an AMD 2700+, not a 2100+. ...This is why I call myself "MEGANOOB".
I checked all my system settings after doing a little more research here at OCForums only to find I quoted the wrong specs for my setup.
After reading some articles I got brave enough to OC some settings in my bios, and manged to come up with approxamatly a 2324 MHz rating for my 2700+, and the temp stayed around 45 deg. C.
Here are the changes I made:
V Core: 1.65 to 1.75
Multiplier: 13 x 166 = approx. 2158 MHz
to: 14 x 166 = approx. 2324 MHz
I tried to set the FSB to 200 with several very low mulitplier settings but the system crashed every time. Is this because my RAM is DDR333?
Do I need DDR400 to set the FSB to 200?
The system profiler that came with the MB says the chip is capable of 3000 MHz. It would be awesome if I could reach that because it is around 900 MHz faster than default settings. I'm not sure if this is possible but I would like to try with some educated guesswork.
Thanks again for the help,
MEGANOOB
