Hey,
I'm having some problems with overclocking my processor

I can't pass 1600MHz FSB. Even though I put 1601MHz, afte rhte reboot I wll get a Long beep & in LCD poster show "CODE INIT"

I tried putting 1650MHz FSB, 1680LHZ FSB etc, but no luck.
My BIOS is 12.02.

Thanks you for your help

It sounds like you need to manually increase the core voltage, FSB (VTT) voltage, northbridge (SPP) voltage, and also make sure the multiplier is still at x9.5.

More later.

No use, I tried that.
& of course Ratio at 9.5

What voltages did you try?

 

[LahiruRD]

Around 1.57 for SB Core, 1.45 for NB Core but I didn't change FSB core

 

[TwoCables]

Was the FSB voltage on Auto? What was the setting for the CPU core voltage?

 

[LahiruRD]

Vcore is at 1.22 & i will see the default FSB voltage

As an experiment, try some more vcore until CPU-Z reads approximately 1.25V, and then see if you can get any more speed out of it.

 

[LahiruRD]

CPU-Z reads it at 1.25V (yes it shows a bit more than the value in BIOS)

I ran this processor at 4.1GHz on a ASUS P5K (Vcore was around 1.35V or something similar)

Oh, then it will probably need a similar voltage.

It's not working even though I put the vcore to around 1.35v.

There's something else.

Did it say 1.35V in CPU-Z? If not, then try that and see what happens.

Finally now my processor runs at 4GHz

Settings are
CPU Vcore ! 1.28V
CPU PLL V : 1.54V
CPU VTT V : 1.32V
Memory V : 1.60V
NB Core V : 1.42V
SB Core V : 1.50V
