You can drop South Bridge back to stock voltages.. increasing it makes absolutely no differences.
Enable Loadline Calibration as this helps with vDroop.
Set DDR2 REF Voltage to nominal (the middle setting).
Disable both Spread Spectrums because they cause instability at high frequencies.
You're not overclocking your CPU? the voltage is set unnecassarily high.

So you don't think I need to touch any of the memory timings or voltages? bar those mentioned in your first post above?

Thanks for your input so far by the way...

What's the max voltage your RAM can take according to spec? make sure you're not undervolting or overvolting your RAM.

Mem timings apart from the ones you set can be left on Auto.
if 4-4-4-12 doesn't post, try 5-5-5-15 and then Memtest, if that post's ok try 5-5-5-12.

You might be better off enabling Transaction Booster and setting it to 0, also set Ai ClockTwister to Strong.
If you find that this works, try putting Transaction Booster on 1 afterwards.
Some people say that Transaction Booster doesn't work properly, but it works fine for me and increased my mem read speeds a little.

If increasing the latency helps you to post, you can probably try to drop the North Bridge volts a little, but that's only worth doing if you are worried about temps! if your NB is staying below 58-60c then you should be fine.

Refer to my post earlier regarding my listed BIOS settings if you are puzzled with setting up voltages.

2.0V is the max according to spec, so I set it to 1.9V to cover the overvolting...

4-4-4-12 is what my mem is supposed to be set at for 800mhz, its the Low Latency stuff...

I'll give all your help a try later and report back, for now you have been very helpful. Its much appreciated!!

Well after your help, I have managed the following so far:



Using the following settings in the Bios:





I shall continue to see how much further I can take it tomorrow!!

Well, as per my post above I am now stumped. Next level is 460FSB from 450FSB. I can't seem to get any higher FSB right now. Any suggestions?

After reading TouGe post earlier I just tried changing Dram static rd: disabled and Trans booster: enabled with a relax lvl: 0 and 1 but it hung on Det Dram. I also tried changing FSB Strap: Auto from 400mhz. I am thinking my memory keeps holding the CPU back but am not sure what to try next???
