I'm currently running a Duron 1100, OC'd to 1250 by 7.5*166 to match my PC2700 RAM, using MSI 6712 mobo. I want a faster chip but can't afford XP2500 or better I've heard that the 1600 and 1800 Durons can be OCd to 2000 and 2250 respectively just by running them on 166 instead of 133 FSB, turning them into cache crippled Athlons. Also heard that the 1600 is happier than the 1800 for this. Does anyone have any information on this? I know they have to be FSB clocked due to AMD locking the multiplier now Also would I be better off with the stock XP2500 instead of the Duron due to the cache level? £30 odd better off? I usually run p2p network 24/7, use PC also for email, web browsing and some gaming (but not much).
