Help me get a better oc from my 3000+

[spacegrass]

I have recently installed a 7600gt sli setup into my rig, and Ive been trying to overclock my cpu so that games run smoother.

At the moment the core speed is 2ghz which is only a little above stock, Ive tried pushing it slightly further by upping the clock speed in bios but the computer wont boot...Im not sure ive done this right.

Anyway, heres my readout in cpuz;

Ive read here people decrease the multiplier, but since you multiply the multiplier with the htt to get your core speed surely this results in a lower overclock?

Im using a ram divider of 333 mhz, my pci-e clock is set to 33mhz and this is my readout in cpuz

core speed 2208mhz
multiplier x9
htt 245mhz

Im now going to raise the clock to 250 and set the ht multiplier to 3, does it sound like im making proper progress so far?

im not going to alter any other ram settings so im not going to change the voltage for that.

my cpu voltage is 1.47, idle temp is 32 degrees

this may be rushing into it a little bit but these are the settings for my 2.8GHz 3000,

FSB - 311
CPU Multi - 9
HTT - 3x
Memory Frequency - DDR266 133MHz
CPU volts - 1.62V
RAM volts - 2.8V
Chipset volts - 1.6V

Effective CPU speed - 2799MHz
Effective RAM speed - 207Mhz

correct me if im wrong but the guy above says you should use a htt of 2?

ok your wrong he said 4 lol, doesnt make that much difference mine is lower cos i have a higher FSB.

ok im confused, what did he mean when he said this then

"When (if) you get to 267 then you will need to lower the divider another notch."
