I've underclocked this little bitch to like 60% of what it used to be. the geforce4 440 Go piece of shit is now 100MHZ core and 300mhz memory. Down from like, i dont know, but i turned it down alot. I have cooling settings set on silent- instead of using fans, it just slows down everything once it reaches high temps, so it can never use its full power. AND ITS STILL OVERHEATING. This is a toshiba satellite pentium 4 2.53 ghz piece of crap old shit. I cant play worms fucking armageddon without it overheating and shutting off.
