Oh sorry. I wrote a wrong things last time !
config "Bank interleaving" and "Node interleaving" are
Bank Interleaving can be enabled, just Node interleaving should be
The northbridge configuration says node interleaving is enabled though.
again the BIOS - the "Node interleaving" was at 'Auto', grr.
After setting it to disabled it works now!

According to Tyan's manual the settings are 'Disabled'/'Enabled',
Disabled as default. But in the real BIOS it is 'Auto'/'Disabled' and
'Auto' by Tyan.
So I recommend all owners of the Thunder K8W to verify the settings.
Or maybe you only have DIMMs in the slots of one CPU.
that the BIOS then sets the interleaving mode, although it's pointless.
It wouldn't make a difference in that case.
I have 4 Corsair 512MB DDR400
modules, connected 2 to each CPU.
Anyways, the performance difference is not that big so
worry too much about it.
Let's see now ...
Thanks for your help,
