[Ahmed1997]

sup quays??
i want to overclock my cpu from 2.83to 3.40
i need the best bios option especially the cpu and ram vcore
and i would to know witch option should change??
and what about the pcie??
my motherboard: gigabyte ep45-ds4p
i have : 8gb ram 4 peices

Older CPUs are OCd only by altering the BUS. So, the first option in BIOS is to desable "Spread spectrum" so it wont affect the other components. RAM speed is going to be affectet alltough... so, you need to play with the ram ratio aswell (lower it). Then start increasing the bus, i say untill you get 3,2 GHz, run stress tests, monitor temps etc, then rais a bit more to 3,3 - 3,4. Dont alter the core voltage, i think you are fine with default.

are you sure the default cpu vcore will enough for 3.40??
the default is 2.162 ??

i think yes, just try it. Set by step increase the BUS and make stress tests. My old Core2Duo didnt need any voltage increase from 2,66 to 3,2 GHz.

ok thx,what about ram vcore and pcie????

Spread spectrum - disable it
Vcore = dont ouch it
PCI-e = dont touch it
RAM- if you have RAM that is able to OC well, then you need to check the frequency to. But first change your BUS, go to RAm and try to keep it @ arround the default speed (if you MB can keep you ram @ the default speed even wehn you change the BUS then you dont need to do that)

Any one have an i dea???
