Chipzilla has announced that it will ship its i7-3960X Extreme Edition and i7-3930K processor in January after fixing a bug which affected the CPU's hardware accelerated virtualisation support.
While C1 CPUs are only running the software-accelerated only mode, the C2 now properly supports hardware acceleration on a hosted OS, Intel said. C2 removes the VT-d bug in C1 CPUs, Intel says.
However Intel does not think that there will be any "change to customer platforms designed to Intel guidelines." If a customer wants to enable Intel VT-d, it suggests "regression testing is recommended to ensure their board is properly enabled."
Regression testing is very important because there is nothing worse than having a server which was once Henry the VIII in a past life, when the software is pure Anne Boleyn. Regression testing remains you can rule out karma for a server misbehaving.
Intel said that customers who prefer their own BIOS will have to install the latest microcode update to support the C2 stepping.
