Should be fine... Most motherboards can overclock this dual core easily as its power requirements are very low. You'll need at least 320MHz system bus to reach 4GHz using the CPU highest multiplier 12.5x, which should be easy on most motherboards. You might need to bump the Vcore a bit to reach 4GHz stable though.. depends on your luck. If you got a golden chip which can reach 4GHz on stock Vcore then you're very lucky.

Take the overclock one step a time .. Test with wPrime or Prime95 for stability, if not increase voltage bit by bit until stable.

The RAM voltage increase option is for overclocking the RAM. Increase this a bit if running the RAM at (much) higher than its rated opertaing clock speeds.

Can... just use Memtest to check RAM stability if running above its rated operating frequency..

That one is for pushing the FSB (to very high, usually above 400MHz). Do not touch that one until you have reached a FSB "wall".

Try to maintain PCI Express frequency at 100MHz. Otherwise PCIe devices might not respond properly to higher frequencies and timings.

Why don't you inquire these stuff at the overclocking section? Moving this thread there...

@uzary... You have to tell us...

#1. System bus or FSB frequency, and CPU multipliers used..

#2. Memory multiplier used, as well as current memory frequency... voltage used for RAM

Under AI Tweaker Menu

Set FSB Frequency to 333MHz
Set CPU multiplier to 9
Set PCIE Frequency to 100
Set FSB Strap to Northbridge to 333mhz
Set DRAM frequency to 400mhz

also...

Set C1E Support to Disabled
Set Max CPUID to Disabled
Set Intel Speedstep to Disabled


Run CPU-Z to check the CPU frequency, also check the memory frequency..

You should get around 3GHz (equivalent to a QX6850)... Run and see if its stable (test with Memtest86, wPrime, Prime95 or Orthos).. If stable then slowly raise the CPU multiplier one step at a time, and re-run the stability tests. If not stabil then raise the Vcore a bit... Your target will be 3.33GHz first (10.0 x 333MHz), then try to reach 3.67GHz (11.0 x 333MHz). Any higher than that then you have to start raising the FSB beyond 333MHz...
