I am using everest 4.60, i have a pretty good 24/7 overclock, i ran super pi 32m windows memtest, running prime 95. I found out why this board wont go over 550, read a review on i4memory on this board, but a very good reviewer, he had same problem 550fsb, 1 mgz over no boot, he said you have to play with the cpu gtl voltages and the board will do 585-590, see on anadtech i read those voltages were for quads, thats why i never touched them, now im going to play with them see how high i can go. I like 1202 bios, it definitly seems a faster boot, ok will post my setting, i have no photoshop so i cant post all cpuz and all that stuff, but will copy and paste the bios settings.
