[ardour-users] [Fwd: Re: Is 64 bit dual core supported and stable yet?]

[George Chan]

I was just about to go out and buy a dual core AMD processor &
motherboard, but after reading this email (see below), I'm going to go
with a dual CPU single core Opteron with an ASUS K8N-DL motherboard.
Tyan motherboards are nice, buy way too expensive for me.

If future dual core AMD CPUs remain in a 940 pin configuration, I can
always upgrade to a Dual CPU Dual Core system.  That may not happen
though.  I recently read that the next generation of Dual Core AMD CPUs
will have a different pin configuration.

If there was no design fault in AMD's dual core offerings, I would like
to have gone with a Dual CPU Dual Core setup.... buying a dual cpu
motherboard with one dual core cpu to start with, then adding a second
cpu when I had some extra cash.

Hope this is helpful.


George

this is caused by a design fault in AMD's dual core offerings. they have
already made it clear that future designs will rectify the problem.
there is a slowly evolving discussion on jackit-devel to try and decide
what to do about it.
