Questions about this item

How can I confirm the Intel Core i7-14700 is running at its 5.40 GHz turbo frequency after setup?

Open Task Manager, select the Performance tab, choose CPU, and watch the speed readout climb toward 5.40 GHz when a heavy workload is applied.

Which accessories are included and which must be purchased separately?

The box contains the SFF desktop, a wired keyboard, a wired mouse, and a 64 GB USB flash drive; a monitor and any additional cables are not included.

Should I choose the 16 GB DDR5 configuration or the 64 GB DDR5 option?

The 16 GB (2 × 8 GB) kit handles typical office multitasking; select the 64 GB version only if you regularly run large datasets, virtual machines, or memory-intensive creative workloads.
