hi i just got my new CPU cooler and started to overclock, but im new at overclocking so i would like some help =)

my motherbord is P6T

[idata]

Ok what may i help you with?

[idata]

what should i change?

so far i only changed the "bus speed" to 160 or BLCK i think its called cant remember

tryed to follow a guide i found but it was for another motherbord so didnt help so much

as in if you know my motherbord i would love some more help there =) got many things i can change but only about 2 or 3 of them were in the guide i found -_-

should i change the Volt (i thing its called) or? =)

also here is my spec

edit again, i tryed with the bus speed at 175 seemed oke but then my wow and firefox crashed at the same time and wouldnt start again

then i got wow up again 5-10 mins later my computer crashed and rebooted no blue screen or anything just reboot

could that be my HDD or RAM?, as my HDD was around 55C at some point

hi

i think you should clear your cmos and start again

and when your at factory settings change the core ratio thats one of the main parts to overclocking

but dont over do it itz best to do small changes and check for stability using a sofware called prime95.

after making changes in cell menu people normally run prime95 for like 6 to 9 hours to make sure it is stable. and if it crashes clear cmos and start again.

and another thing be sure to have a good cpu cooler the original factory one aint cut out to take the heat from a overclocked cpu.

stay away from voltage for now just a hint.

i hope i helped

good day sir

oke thx and i do have a much better cooler then the standard cooler

[idata]

what cooler do you have as you can reach 4.0ghz if you have a good one usually go for 200 blc feq and a ratio of like 20 for the multiplier try a voltage of 1.36825 or around there!

[idata]

the voltage is what you realy need to watch out for thats why when you set the voltage go for 1.368 or higher when reaching 4ghz my core i7 870 is at 4.04ghz and has a voltage of 1.375 so you have to mess around with it first!

oke

my cooler is Noctua NH-D14
