Dell Precision 5820 Tower compatibility

Hello all, 

I took out my i9 9980xe and dropped in an i7 7800x but I can’t seem to figure out why it won’t post. 

Bios 2.44.0 (latest)

Motherboard 02m8ny

Am I missing something? Every time I put the 9980xe in it posts with no issues but when I drop the i7 7800x nothing shows up (caps lock light on keyboard turns on but no display) I know that the i7 7800x works bc I tested it in another motherboard. Any help is greatly appreciated.

Hello,

sorry for asking but ... why do you want to downgrade ? the i9 you are currently using is way more powerful than that i7

Unsupported configuration?  Check the owner's manual and see if the same configuration (namely RAM configuration) is supported with the I7-7800x.

Not sure why you'd want to downgrade, are you selling it?
