Hello,  I am curious if anyone has been able to get a xeon processor to work in one of these OptiPlex Desktops.  I have a 9020 MT with the most up to date bios installed recently.  currently I have a 4590S installed.  I am wondering if a Xeon 1230 v3 would work.  I know it is the same socket / chipset but not sure if there is a reason this won't work in the Dell.  

I understand that the Xeon is not listed on the Dell site as supported.  However, I have seen Xeon's used before on other boards that didn't list it as a supported CPU.  

Thanks!
