first your board has this
C.P.R.(CPU Parameter Recall)
When the system hangs due to overclocking failure, there is no need to open the case to clear CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again.
As for your list of 6 items - jesus it all wrong, did you even read oc101
1- Set cpu speed to manual, Set Vcore set to Manual
ok this is the setup for a non oc'd system (not too sure about the use of the words "cpu speed to manual" it that what the option says in bios? try to use the same terminology. I have your bios manual in front of me and this option is not immediatly apparent to me.)

2-Set cpu Frequency Multiple (mhz) to 266/44
That is too high a jump for your first step. And i assume that the 44 is you pci/agp speed - which should never ever exceed 33mhz. But acording to the manual you pci/agp settings dont even go that high so lord knows what your talking about here
What you needed to change was the setting called CPU External Frequency in the section of bios called JumperFree Config (page4-19 in the manual). Increase this slowly at a rate of about 3-5mhz each time.
3-Set memory frequency to 400mhz from auto
Fine, you dont want to oc you ram
4-Set cpu vcore to 1.5000V
Well you set this to auto in step one???
You only increase this is you cant boot stably with your increased CPU External Frequency (see step 2 above)
5-Set DDR Voltage Adjustment to 2.7V from auto
Fine, you shouldn't need to increase the vdimm if your not ocing your ram. May be need to do this later for stablilty issues as we increase CPU External Frequency (see step 2 above)
6-Then went to chip config under advanced and set the graphics aperture to 256MB from 128 MB
What, why. Did you see this discussed in oc101
