Do Xeons overclock at all?

Xeon's generally go in workstation and server class machiens which people want to run in specs. The overclocking features of Xeon systems are probably few and far between, particularly on a big name OEM system like an HP.

Xeons are limited to 533MHz FSB because of signaling with dual (or Quad) support? Any word as to faster FSB for Xeons? How hindered is a Xeon by the FSB compared to a P4 with 800MHz FSB?

You just need the right motherboard, search the cpu/overclocking forum as their is a thread their

800 MHz fsb Xeons will be released in 5 days. These new Xeons will come with 64-bit capability, and two speed bumps from the current top 3.2 GHz to 3.4 and 3.6 GHz. I suspect but don't know for sure, that the 512 kB cache chips are dead (meaning these new ones will have 1 or 2 MB cache).

Could lead to data corruption if the agp/pci bus speed were raised due to overclocking which is a big no no.

Not only does the slower FSB hold back the Xeons, but having to share the FSB bandwidth between two processors really holds back Xeon performance compared to an Opteron system where an on-die memory controller on each processor allows each Opteron to use their own dedicated memory modules (dual channel modules in some configs). The bigger L2 cache on the high end Xeons helps to allieveate this bottleneck, but as you scale to 4 and 8 way configurations, the Xeon just doesn't have enough memory bandwidth to keep up with a comparable Opteron system. Also, the higher the Xeon's clock speed gets, the worse the bottleneck becomes.

Anand on why you don't want a quad Xeon server.
