i was soo mad when i woke up this morning to see that this pos i've built can even sustain 2.4ghz speeds at 255fsb for 3 hours in p95 that i decided i would post all of my info for the pros..
ok i've been at this for 3 weeks, 3 different boards (abit,asus, now dfi ), 2 different cpus (pIIII and now x2 3800) and 3 types of ram. all i have to show for that stuff is a bunch of oc settings, none of which can sustatin p95 for more than 4 hours on both cores.....very sad...considering i feel i have some of the best equipment... I've gotten very nice OC's but nothing close to what i feel i should be getting or close to what other ppl are getting and obviously nothing stable.
btw; i do all of my oc'ing in the bios, should i be using something like A64 (just for speed in testing, i know bios #'s are better)?
(attached are 3 screen shots from a64 tweaker, and cpu-z )
soooo..
ram= geil one s 2x 512mb (GOS1GB3200DC) (PC3200 DDR 400 CAS 1.5-2-2-5

255fsb / 9.5 multi (i know it devides) / 1.525 * 110% vcore, 1.7v chipset / 2.8v ram / 480w cool max silent PSU (i measure the 12v at one of the connectors, always 12.25-12.05v with anything i throw at it)
heat is not an issue, except the system temp somes times goes to 60c... cpu always < 56c usually 53c load or less

thanks guys! maybe this can be a good weekened after all
