I and many other MSI K8N Neo4 Platinum SLI users are experiencing a FSB bug (or HTT bug) that prevents overclocks higher than 220MHz on POST with the Winchester core.
All others, NewCastle and Clawhammer, are Overclocking just fine.
It appears to be a BIOS issue, as you can overclock while within Windows XP to higher levels, you just can't reboot at those levels.
Please warn your users that may be thinking about a Winchester core and the MSI board to either purchase a NewCastle or wait for the BIOS update.
Hurry up MSI!
