The fact that the .pdf you linked to is buried several layers deep on the Dell website only solidifies my argument that it shouldn't take this much effort to find valid information such as that.  Furthermore, the 1.12.0 BIOS update simply states further support for more 5600 "SERIES" processors. The specsheet.pdf for the server states 5600 "SERIES" both of which are more easy to locate than the .pdf you linked to (i.e. Google Poweredge t410)  The technicalguide.pdf you linked to only solidifies my sentiment that Dell needs to be more clear about their documentation. Example 6.1 Overview (table 8) The Poweredge t410 provides support for up to two processors. It then lists 95 watt and 130 watt. Furthermore it gives reference to a set of supported processors but only goes up to the X5650. It gives no reference of what BIOS version was used during testing, however the date-stamp on the .pdf indicates July of 2011 but the newest BIOS version is from 2013. I hope with these examples you will be able to see that simply "assuming" things as "good indicators" can trip-up the most seasoned Sys Admins.  And FWIW the X5675's are the fastest highest watt TDP processors that can run in the T410. Thanks to me for figuring that out...  No response is necessary as I don't care anymore nor will I read it.
Anyone know if the PowerEdge T410 with the 1.12.0 BIOS is compatible with Xeon X5680's? The release notes indicate the system is compatible with 5600 series processors but I am unable to get the server to actually boot with them installed.  What I have tried: Reset BIOS - NO-GO- Reflashed BIOS to 1.12.0 - NO-GO- Removed all other processors and RAM leaving only bank 1 - NO-GO- Installed a single (didn't have another) "known-good" X5650 6-Core 130watt processor - ALL-GOOD- I am now under the impression that BIOS 1.12.0 is NOT compatible with X5680 processors. Can someone assist and verify this for me? My Google-Fu is not returning any results... Thanks in advance for your time... >Aaron
