780 USFF - upgrade CPU to AES-NI

hello - i am looking for advice on upgrading the Intel E8600 CPU in this optiplex 780 USFF. 

i need a CPU that supports AES-NI because this is going to be repurposed as a pfsense/opnsense router.  I've removed the front bezel and replaced the front I/O board with a Jetway ADMPEIDLB 2-port Gigabit LAN - Intel i350 - mini pcie network card.

I see it is possible to install an lga-771-to-775-adapter but the system board is not compatible with Intel 5xxx series ..

so can I replace the stock motherboard with a newer model? swap in a motherboard from another newer dell USFF? or purchase a non-dell motherboard that will fit in this USFF?

No such thing.  All Dell motherboards are Proprietary.

Re: 780 USFF - upgrade CPU to AES-NI

Advanced Encryption Standard Instruction Set (or the Intel Advanced Encryption Standard New Instructions; AES-NI) is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD. Has nothing whatsoever to do with any specific motherboard. Has to do with the Processor.  LGA 771 and 775 need not apply because its not there.

The following Intel processors support the AES-NI instruction set:

Westmere based processors, specifically:
Westmere-EP (Xeon 56xx) (a.k.a. Gulftown Xeon 5600-series DP server model) processors.  Socket 1366 aka Dell Precision T3500  or 2010 Mac Pro Tower.

Clarkdale processors (except Core i3, Pentium and Celeron).


Arrandale processors (except Celeron, Pentium, Core i3, Core i5-4XXM).


Sandy Bridge processors:
Desktop: all except Pentium, Celeron, Core i3.

Intel® Xeon® Processor X5650
(12M Cache, 2.66 GHz, 6.40 GT/s Intel® QPI) DDR3 800/1066/1333

 The Late 2010 Spec sheet says.

  Intel® Xeon® 5600 series processors up to six-cores with up to 6.4GT/s (Intel QuickPath Interconnect) and up to 12MB shared cache. Turbo Boost Mode on select processors


All processors are 64-bit, support Intel DBS (demand-based switching) and Intel VT (Intel Virtualization Technology) Note: Intel TXT is not supported. Turbo Mode and HyperThreading technology on select processors

If this is a headless router then I would choose an R710
