I am using Dell T3620, Is it compatible with i7 9700k?
The short answer is NO
An Intel i7 9700k CPU is not compatible with the chipset on your motherboard. It will not work.
According to the specifications for your motherboard it has an Intel C236 chipset.
Here’s a link that states that 8th and 9th Gen CPUs are only compatible with Intel 300 series chipsets and are not backward compatible with Intel 200 series or Intel 100 series chipsets
