27-inch FHD All-in-One for business

Suited for office productivity and video calls

Workers who need a compact desk setup with a built-in HD TrueVision webcam, Bluetooth 5 and Gigabit Ethernet will find the connectivity complete. Buyers who want more internal storage or a discrete graphics card should look at a tower workstation instead.

64 GB DDR4 SODIMM memory capacity

The system provides 64 GB of DDR4 memory in a SODIMM 204-pin form factor, which determines how many applications run simultaneously without paging. Verify that this capacity matches your workload before purchasing.

Questions about this item

How do I install extra DDR4 memory in the OptiPlex 7770, and which slot type should I match?

Open the rear cover, insert the 204-pin SoDIMM module at an angle until it clicks, then press down flat; the system uses DDR4 SoDIMM slots so desktop DIMMs will not fit.

What maintenance will the 256 GB SSD need over time?

The 2.5-inch 256 GB SSD has finite write endurance; monitor health in Windows and replace the drive when capacity or SMART warnings indicate wear.

What thermal limit appears first when the i5-9500 runs at 4.40 GHz continuously?

Sustained 4.40 GHz turbo on the 6-core i5-9500 raises package temperature until the all-in-one cooling hits its thermal ceiling, causing the processor to throttle below maximum frequency.
