The box works as it should with 16GB if I disable node interleave in
BIOS. The machine was also unstable with RedHat EL WS 3.0r4 (which is
supported according to Tyan) so this is probably a problem with the
BIOS not being 100% compatible with the memory sticks. Having 4+2 sticks
installed disabled memory interleaving so that is why I thought the
problem was associated with memory size.
This Tyan nForce Pro board does not feel mature at present so don't buy
it unless you like to fiddle with settings and numerous BIOS upgrades.
Some BIOS versions will for example NOT boot from a PCI express RAID
card! There is a fan site with more info and help at www.k8we.com.
Personally I'm waiting for the Supermicro OEM boards until I try this
