Need some help overclocking

wtf?

got me i figured my internet crapped out. both my broswers sure did. couldn't get them to work on this web site at all. well i guess it's working now. doesn't make much sence since i should have posted something , even blank, with my name on it. not just completely empty.

anyways with that said on with the question. i have a 2500+ and i was running toast on it today at 175*12.5=2186. i had a vcore @ 1.868 and it was stable for 4 hours. i had a table fan blowing into the case to keep it cool. kept it at 55c-56c w/stock. still working on getting an aftermarket hsf for the cpu. i lowered the vcore afterwards to 1.772, which is what it is at now but when i try running toast again it rebooted. i also have prime95 and have yet to try it but it was stable for the hour i had it running at 2800+ speed with the vcore@ 1.772. i know that 3000+ runs fine with a vcore @1.66, atleast i think i know and was wondering if there was something i had to do to get it stable on toast at a lower vcore. or could it just be that my board is a rev 1 and it was never ment to do this kind of speed( i picked it up a week after it was released).

thanks for the help and wish i knew how this post was posted without what i had typed in.

You are simply reaching the limits of your stock heatsink. It has nothing to do with the motherboard. When you need to put in large amounts of increased voltage for small returns in clock speed, it means that you will soon to be reaching diminishing reutrns, which means you're going to either need to run with a high core voltage, or upgrade your cooling. When you get a better HSF, you will encounter this phenomenon again, but at far higher speeds.
