Questions about this item
What bandwidth does the Thunderbolt 3 port on the Precision 5520 provide, and what does that cap in practice?
The Thunderbolt 3 port delivers up to 40 Gbps, capping external GPU and storage speeds at that ceiling.
What physical slot and form factor does the 512 GB SSD use inside the Precision 5520?
The 512 GB PCIe NVMe SSD occupies an M.2 2280 slot on the motherboard.
How is the RAM installed in the Precision 5520, and what step do people often get wrong?
The 16 GB DDR4 2400 module is soldered, so there is no slot to populate; the common mistake is buying a SO-DIMM that cannot be fitted.
