Hello,
I my CPU i5-6500 is bottle necking so I want to upgrade my CPU I found out that i7 6th gen or 7th gen is the max but that was just a little bit better then my current CPU and it was much expensive in my country, Then I did a deep research to find a CPU that is LGA-1151 6-7 gen and supports DDR3L then I found about these Xeon CPUs like E3 1280-v5 that supports same motherboard type and also supports DDR3L I just wanna know that the OEM optiplex 3040 sff mother board supports all CPU under its type.
Regards
