hey guys, just built my first almost-new rig the other day (opty 146, epox 9npa+, x1800xl, 2*512mb twinmos bh.5 3500, hyper 580W psu)
As soon as i got it (i know i shouldn't) but i whacked the fsb to 280mhz (1.55vcore running the ram on a 166 divider at 2-2-2-7 with 3.2v). It worked perfectly fine, prime95 stable for 8hrs+. (cpu at 43 degrees)
I ran super pi and got 1mb - 29s and 2mb - 1m 7s. Are these good scores?
I don't know where to go from here though. I tried booting at 3ghz (with divider now on 133 and very slack timmings) and I got into windows. Prime95 failed pretty quickly though and superpi wouldn't finish.
I want to try increasing the vcore but don't know what my limits should be. I'm not really intrested in benching, just want the get the highest clocks i can get my pc to for 24hr everyday safe stable use.
Thanks for any help.
P.S. can harddrives cause stability issues? And yeah i dont recomend the epox to anyone looking for an overclocking 939 board.
-The chipset cooler is very loud.
-Installing a gt or xl will render one of the p-ata slots inaccesible.
-The cmos jumper and battery are also directly below the pci-express slot so the jumper cant be reset without taking the gfx card out first.
-The motherboard undervolts the cpu when under load. ie set to 1.55 in bios but when running prime95 it undervollts to about 1.49?!?!
Sorry for the long post. Any help appreciated

1.59vcore and 45 degrees load. Had to put mem on a 133 divider though. Well at least i know what my opty is capable of. Currently priming (25mins and counting)
