|OK, I did some digging & it appears that the memory setting is probably the major thing that's holding you back, plus you haven't mentioned anything about changing any voltages? The voltage settings aren't listed clearly. Here's what I've found:|
1.8V Dual Over Voltage = RAM voltage
1.5V Over Voltage = PCIe voltage
VTT_CPU Over Voltage = CPU voltage
1.25V Over Voltage = northbridge chipset voltage
The only ones you should need to play with are the RAM voltage & CPU voltage. Do you know what your RAM voltage is supposed to be? The JEDEC standard sets the default voltage for DDR2-800 at 1.8v. However, the majority of RAM manufacturer's do not conform to the standard. Find out what your RAM voltage is supposed to be & change the 1.8V setting from AUTO to the closest setting available.
Do the same with your CPU voltage setting. I believe the default for your CPU is 1.24v? Go to the Hardware Monitor menu & see what the VCORE Voltage is listed as. Assuming it is 1.24v (or thereabouts), change the VTT_CPU setting from AUTO to 1.3v.
Also, as long as you choose one of the standard CPU frequencies (200, 266, 333, 400), the PCIe will run at it's default speed of 100MHz.
After doing the above, try the following as an experiment:
Under Advanced > JumperFree Config:
AI Overclocking = Manual
CPU Freq = 333
DRAM Freq = 667
Under Advanced > CPU Config:
CPU ratio = 8
CE1 support = disabled
Max CPUID Value = disabled
Vanderpool Tech = disabled
CPU TM = enabled
Execute Disable Bit = enabled
Intel SpeedStep = disabled
Make sure to "Exit & Save Changes".
If the above settings work (& I did my math correctly), the CPU will run at 2.67GHz with the FSB at 1333MHz & I *think* the RAM speed will be approx 417MHz (DDR834).
Remember, this is just an experiement. Use CPUZ to confirm the settings.
