Im thinking about upgrading, and Im wondering is there any advantage
to going with a server board instead of a standard board, or are there
more limitations. I know I will be giving up sli but I have
determined that the gains of sli is not worth the cost at all. Im
hoping that if I do go to a server board that I will have a much more
stable computer.
Server boards:
1) One, two, four CPU sockets. Eight sockets with extender assembly.
2) Large form factor, 12" x 13", needs a special computer case for
the largest of them. Even at 12" x 10.5", could be difficult to
fit in an existing computer case.
3) Generally no provision for overclocking.
4) Likely to have working ECC/chipkill for memory. So ECC DIMMs
can be used. Some desktops support ECC, and some don't. And
some desktop BIOS don't configure the ECC correctly, when
ECC DIMMs are installed.
5) Memory subsystem could be registered memory or FBDIMMs.
Server owners care less about the bandwidth they get, as for
some server tasks, the amount of memory is more important.
Having 64GB of memory, may be more important than having a
smaller faster memory subsystem, that is swapping to disk all
the time. Registered memory or FBDIMMs, may lose out when
compared to desktop memory configurations, on bandwidth.
6) Server boards have enhanced I/O systems. They have PCI, PCI-X,
PCI Express, or even slots for custom I/O types. If you need to
get a 400MB/sec disk subsystem connected, then a server board
should have the slots. Desktop systems in the past, have been
dismal in that area, but with the introduction of PCI Express,
and SLI boards, you can stick high bandwidth I/O into a desktop
board. Just not fill the computer with high bandwidth controllers,
like you can on a server.
A desktop board does not have to be unstable.
And server boards are not always stable.
One Photoshop user in the Tyan group, was recently complaining about
problems with his expensive Tyan board. So server boards are not
guaranteed to be trouble free. They may need more attention from the
owner, in setting them up. There may be fewer other users, to help
with technical issues. And if you visit forums.2cpu.com, there
are more horror stories over there, of products that did not live up
to their billing.
If you had described the applications you had planned on using,
then that may help focus the feedback you get on your idea.
