Xeon's / Multi's / Halogen Question's

Zerk here with another creepy Question.


Do the Xeon CPU's have unlocked Multipliers ? or are they locked?


If they are locked does anyone know Why?

also, is it harder to make a CPU with an Unlocked Multi vs a Locked one?

Also, what is the reason for making some CPU's Halogen free?


Thank you!

    Server parts value stability and reliability over overclockability. Also no server component provider would support overclocking as it introduces only new possible problems rather than benefits.

    It should be the same as making any other cpu, aside from the bits that lock the multiplier. The manufacturer however needs to validate that it runs at all the multipliers properly which may take more time than a locked multi.

    These are mostly environmental protection reasons, see ROHS. A few micrograms per processor of a toxic substance quickly adds up to a few metric tons when you are producing thousands of chips a day.

    Good answer!

    That is true, but if I may add: Sever CPUs are quite good for overclocking, for example the old Opty 185(?IIRC) and Xeon E3110 OCed quite well (compared to their non server counter parts) with a good motherboard. I remember people getting the E3110 instead of the E8400 as the E8400 was ~$50-100 over priced @ Newegg due to demand lol.
  4. Great, I have a 790I Ultra mobo, EVGA does not list Xeon's as a Compatible CPU.

    Will they work ?
  5. ^Usually, they should work.
