On Fri, Jan 27, 2006 at 11:03:10PM +0100 I heard the voice of lars.tunkrans@bredband.net, and lo! it spake thus: > > Correct, Opteron uses socket 940 to be able to use registred ECC > Ram. Whilst modern Athlon 64 uses socket 939 to cut the cost of > the motherboard components and to use unregistred non-ECC RAM. Opteron 1xx uses Socket 939, and A64 supports ECC RAM. As far as I've been able to tell, the primary difference is that the 940 motherboards tend to support registered memory while the 939's generally dont, and the 2xx and up Opterons have the extra HT links for multi-package systems. And perhaps some of the Opterons have more cache, I'm not sure. The difference became awful awful blurry when Socket 939 and dual-core A64's came around. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
