ProDesk 600 G5 SSD Upgrade Guide
The ProDesk 600 G5 supports M.2 NVMe drives via PCIe 3.0 as well as standard 2.5″ SATA SSDs. NVMe drives offer significantly faster read/write speeds compared to SATA.
M.2 NVMe Installation
- Power off and open the chassis as described above
- Locate the M.2 slot on the motherboard (typically near the CPU or front panel connectors)
- Remove the M.2 mounting screw
- Insert the M.2 drive at a 30-degree angle into the slot
- Press down and secure with the mounting screw
- Reassemble and boot — the drive should appear in BIOS automatically

A: The ProDesk 600 G5 uses DDR4-2666 unbuffered DIMMs (UDIMMs). The SFF model has 2 DIMM slots supporting up to 32GB, while the Tower model has 4 slots supporting up to 64GB.
Q: Can I add an NVMe SSD to the ProDesk 600 G5?
A: Yes, the ProDesk 600 G5 supports M.2 NVMe drives via PCIe 3.0. This is the recommended upgrade for maximum storage performance.
Q: Is the ProDesk 600 G5 RAM compatible with the ProDesk 600 series?
A: RAM compatibility depends on the specific generation. The ProDesk 600 G5 uses DDR4-2666, which is physically compatible with other DDR4 systems but the speed rating must match or exceed the motherboard’s requirement.
Q: How do I check how much RAM is currently installed?
A: Open Task Manager (Ctrl+Shift+Esc), click the Performance tab, then select Memory. This shows total installed RAM, speed, form factor, and how many slots are in use. Alternatively, press Win+Pause/Break to open System Information.
Q: Can I mix different RAM sizes in the ProDesk 600 G5?
A: While the ProDesk 600 G5 can technically run with mismatched RAM sizes, it is recommended to use identical modules in pairs for optimal dual-channel performance. Mixing sizes will cause the system to run in flex mode, which reduces memory bandwidth.
