Dell Dimension E521 Processor Upgrade

My E521 came with the AMD Athlon 64 X2 Dual-Core 4400+ processor and I read on some other threads that the AMD Athlot 64 X2 Dual-Core 6000+ should work, as long as I got the 89w version.  I purchased the following:

AMD ADA6000IAA6CZ Athlon X2 6000+ AM2 3.0GHZ 2MB 90NM 89W 2000MHZ TRAY

I am running the latest BIOS (1.1.11), running Windows 10.  However, my system doesn't recognize the new processor.  It boots, but still shows the 4400+ processor when I view the properties under "This PC" and also in device manager.  I even try scanning for new hardware in device manager, but the system doesn't see it. Another strange thing is that the 4400+ processor shows up twice in device manager under processors.

What can I do to get it to recognize the new processor?

Boot into the bios. How is the CPU listed in Processor Info? Boot back into windows. Download and run CPUZ. How is it listed?

The Dell internal parts page for this model does not list a 6000+ CPU. The highest validated are =
DR246 AMD Athlon 64X2, 5600+, 2.80GHz, 1MBX2, Dual Core, 89w
PU630 AMD Athlon 64X2, 5600+, 2.80GHz, 1MX2, Dual Core, 89w
