Recently bought Dell PowerEdge R710 that seems to be Gen. 1 - iDRAC reports System Revision I, and the id number of the motherboard is 0N047H. The number on the actual casing is different though - its 0H241F and I suspect its probably predefined configuration sold by Dell.
My use case require fastest, highest core count CPUs that i can put in it. I believe that should be Xeon X5675 and just to be on the safe side I asked in Dell forums since they are notorious when it comes to NOT giving specific information about supported CPUs on their systems. A Dell moderator/engineer said that Westmere 5600 series CPUs are NOT supported and system support only 5500 Nehalem CPUs (you can read here). Well, my system came with two E5630 so their answer is either inadequate or Dell think this system should not exist.
Thats why I’m asking if someone here have actual experience related to that matter.
