Question: why is not northbridge functionality is not a part of the

route.

Is that why dual socket AMD motherboards suck?

At least for CoreDuo. The reason I'm asking is that the son of a gun is
hotter
than cpu anyway. Are there dual socket CoreDuo mobos?The Xeon 51xx series are essentially dual socket capable Core2 Duos.

I haven't seen any. Dual socket is only a Xeon thing?
I assume having northbridge for dual or a quad machine separate from
cpu would
make sense, but for CoreDuo??? It's not like there is a lot of memory
types to
support these days.I've benchmarked dual core Opterons vs. Xeon 51xxs, and it's only in
*really* memory intensive codes that the Opterons onboard memory controller
shows up. This in stark contrast to pre-Core Xeons, where the memory
performance was truly hideous.

I'm not so much concerned with performance as with correctness.
(I put much more faith in the Intel QA department)
Oh, and I can fry eggs on my G965 northbridge. Dunno if it's the memory
controller or the graphics. Won't be surprised if X3000 generates a lot
of heat
and P965s run much cooler. Anyone with P/Q965/963 care to comment
about northbridge temperatures?
