My System Specs

As in 22k in Windows to 30k in LinuxVM? If so, that is a 180 from my previous experience with vbox. Sounds like somewhere between then and now they finally managed to figure out the "symmetric" part of smp. Thanks for the info!

The Intel D5400XS (the one I have) and ASUS Z7S-WS are the two boards comprising the Skulltrail platform, and they are a bit unique compared to other dual-S771 boards insomuch as they boast traditional S775 overclocking features in BIOS. So there's no need to mod the CPUs or sockets directly in order to achieve higher fsb speeds (yes, remember fsb?). Unfortunately, the server-class chipset and its reliance on fbdimms restrict the platform's fsb ceiling quite a bit, and not a lot of people are able to OC it much higher than 420 fsb, so there's only so much opportunity for OC'ing Xeons and very limited opportunity for 1600fsb Xeons. That's why the unlocked QX9775's are a better fit for the platform if overclocking is your goal.
Think you can overclock? Then show us what you got!
