CPLB: Nice to see that you could hit 350MHz too.
Set the LDT divider to 2 or 1 and see if you can get higher. You also have to set chitset voltage to the max (which is 1.325V if I am correct). With a LDT of 4 I cannot boot 350*4.
elfy_008: Overclocking is not that hard on K8. Lower the LDT multiplier, so that FSB * LDT <= 1000MHz. Then raise the FSB in 5MHz steps and run Orthos for half an hour or SuperPi 32M on each core. If it doesn't fail, raise the FSB another 5MHz (all in the bios) and run those applications again. If they produce an error, you have to either lower your overclock again or increase VCore by a little step. Use CoreTemp or any other app of your choice to monitor temp. +0.15V should be no problem in case you have decent cooling. At a certain point you will have to raise chipset voltage too. When you think you have overclocked enough, run Orthos for 15-24 hours. When it runs that long without an error, test 3D applications. If they are also stable, your overclock was successful. If not, lower FSB again and run the tests again until it is stable.
If you want to test the max FSB of the board, set the LDT to 2 or 1, set chipset voltage to the maximum (1.325V), FID (CPU multiplier) to 4 and raise FSB until you cannot boot any more. If the board fails to boot, switch the PSU off, press the power button to get rid of power left in caps, set the CMOS jumper below the PCI slots to the other position, wait 5 secs and set it back again. Then you can power on again. Before you start messing with the bios settings, better save your current (working) config in one of the 50 profiles, so in case you have to do a CMOS clear, you have your old setting back in no time.
