My old P4 I got in 2004 overclocks very well, too. I set it like that soon after I got it and it runs solid as a rock like that to this day. One of the most stable systems I've ever had. 2.8GHz Northwood with HT o/c 3.5GHz Abit AI7 motherboard. Ah, Abit, how I miss thee.... 2GB DDR400 Geil RAM as 4 x 512MB AGP graphics card: whatever I feel like plugging in today. lol Tell you what though. Solid as it is at 3.5GHz, try for 3.6GHz and the system turns to jelly. Just won't do it stably, no matter what.
