If you wanna stick with RedHat, download a newish kernel source and compile it with HyperThreading options. __________________ Ma homeboy is Jesus himself.

Most distributions these days will detect a hyper-threaded CPU and install the correct kernel automatically. __________________ Registered Linux user #270181 TechieMoe's Tech Rants

Thanks for the reply!

Which Fedora Core do you recommend for my server?
