Well thanks to some help from A.N. Other on another thread have actually managed to overclock my Athlon 64 3700+ to a decent level-well decent for me. Have got it running at 2808.7MHz with HTT at 255MHz and an 11 Multiplier and still got the memory running at 200MHz with timmings of 1T 2-3-3-6 all on stock voltages and temps at 44 cpu,32 sys and 44 pwm. So far it has passed Memtest and Prime 95 has been running without fault for 3 hours so far. So do you guys think thats a reasonable overclock-do you think i would be pushing it to go higher? Thanks again to A.N. Other cause I coudln't get anywhere following any the other guides.
