Hi, not sure if the speaker is correctly connected, I only think it
is!
The ram is Corsair Dominator TWIN2x4096-8500C5DF G.
You know, I think that's exactly the same RAM and board that I saw the
same problem with. Borrow another stick of less fancy DDR2 to test. Use
DDR2-800 or 667 because the boards often don't boot with 533 or 400.

Flashing the BIOS with the latest update did make the board work fine
with the Dominator sticks. Obviously you can't do this unless you have
it booting first.

Just checked the speaker connections and the red wire is on +5v and
the black wire is on Ground, if that is correct?
Yeah, you can wire it backwards and it still works too.



So... if the speaker is connected between +5v and ground, where does the
sound input come from?

Just checked in three Asus manuals and all indicate +5v and "speaker
out". Many cases have a "4 pin" connector then not much can go wrong,
but some have two individual connectors.

ok, just swapped acrros the black wire from ground to 'speaker', but
stil no post/beeps.
Do you think then its the ram now, at too high a voltage, ie nit needs
2.1v against others at 1.8v?

Thanks

That could be a problem - (effectively) unlimited 5v across the speaker
may have caused damage. You try a 1.5 battery across the speaker leads
to check it make a noise (use a couple of paperclips as pins!) :-)

The m/b manual and memory specs should identify if the memory voltage is
a problem.

I tend to keep a few old video cards for times like this - ISA, PCI and
AGP - though getting an integrated board and then adding a card is
simpler (if you don't want a cutting edge system).
