Asus P5E3 Premium Wi-fi-AP

You shold set the NB voltage manually. When you want to run your memory (2x1Gb) at 1800Mhz it needs about 1.6 - 1.65v. I run mine at 1780Mhz with 1.65v stable.

Isn't 1,65v on the NB a bit high?

I think it is for 2x1GB at 1800...

Was messing around today, and atm have a 450 FSB with 4x1GB of mem running 1800Mhz 8-7-6-18 1N with 1.80V on the memory and 1.45V on the NB
Haven't tested full stability yet and may still need small adjustments, but just passed 5 loops of the IntelBurnTest by AgentGOD


[edit]
I've also noticed that the minimum values in the BIOS are just like the Auto setting.
Setting 1.10V for FSB, 1.25V for NB. does not fix the values, they will still change/increase as you overclock (checked with a multimeter)

I have my system running now at 400fsb 333NB strap (8 multiplier) which put my memory at 1601MHz. I jumped it up to 425 and the memory went to 1700MHz. I will post my setting a little later as I want to ask the question about the fsb/dram ratio, it is set to 1:2 per CPU-Z. How does one go about changing this? As I increase the FSB I do not want to overclock the memory to far.

The BIOS does not show the ratio, instead it gives DDR3 speeds. In the AI Tweaker section, depending on the FSB Strap setting in the BIOS, you will have different memory speeds to choose from under the setting "DRAM Frequency"
