if this has already been posted please point me to it 
basically, ive got the rig in my sig (catchy, no?) up and running again, and im having problems ocing the FSB/Base clock/reference clock/whatever its called nowadays.
as im sure all of you know, the base speed is 200mhz, and on my old board it would top out at 240 mhz before artifacts would appear on the screen (igp left at stock speeds). wondering if this may be one of them stability holes, i carried on, but it wouldnt boot at anything past 250, at which the screen was almost completely unreadable. At the time, i merely accepted this fact, and carried on working around this, but most other boards would easily be capable of 270+mhz
then i accidentally killed it when the power tripped during a bios flash. fast forward 3 weeks, and im now trying out the RMA replacement. Has exactly the same symptoms as the old at the same speeds, but with a new twist. once i go over 230mhz, the system will be perfectly stable, untill i stress the IGP (still at stock), and then the system will crash anywhere between 30secs-10mins. atm everythings hunky dory @ 225, but i could really use with more, as the ram will only run at 1066mhz (bios bug), and a fsb of 250mhz will bump this back up to 1333. i cant update the bios, as i will lose my core unlocking goodness.
so, if i go discrete (which i eventually will), will i see any better results?
Note, upping the voltage on the nb only has the effect of <70.C temps on the nb when IGP is stressed. Also, bios update only solves ram speed issue, doesnt affact overclocking in the slightest...
