"Proper" Method to OC Mobile Barton?

Got a new mobile 2600 and want to OC. What do you do first, try to max FSB or multiplier? Or do you have to move both around until you get stable? What to leave RAM timings at while you're playing to get stable? got some pc-3500.
 
I would say find your limit on the cpu first, ie increase the multiplier and keep fsb low (below 170ish), those chips in theory are default at 133fsb. Once you have the limit of the chip, then raise the fsb and lower the divider trying to find a good fsb, that your memory will run and keeping the core near that max you found.
 
^^^ not the best way to go

my way: pc3500 can go 215fsb
lower ur mult to something low like 10
up ur fsb SLOWLY to 215
up voltages if necessary
after u reach 215 fsb start upping mult by 0.5
up voltages again if necessary

stop when u reach 1.85 Volts on Air
or 2.1volts on prommie
 
Just my $.02 here...

I would do the opposite of the above. That way you can determine what the maximum limit is of your CPU, and move forward from there. If you crank the FSB, and it won't POST, you might blame the CPU when something else could be the issue.

Go as high as you can with the clock, at a voltage/temperature that isn't insane, then bump the FSB until it won't go any further. Test for stability at each bump. See, I think some people don't test it enough, and get pissed when their machine crashes, and blame Windows. Stability testing is the most important part of overclocking.
 
I always find the max FSB first, then bump the multi until it won't go any more. Add a little V, and try for some more. On air I stop at 1.85, and 1.95 on water. The chip in my sig will run at 2500, but the drop in the FSB actually makes the system slower.
