Dell OptiPlex 5060 Micro upgrade guide

Lifecycle and support

Memory (RAM)

The Micro has two SO-DIMM slots (260-pin, DDR4, 1.2 V) and no soldered memory, so both slots are yours to upgrade. The ceiling is 32 GB total: 16 GB per module is the maximum, and 32 GB single sticks are not supported. The memory must be non-ECC and unbuffered — desktop DIMMs won't fit the slots, and ECC or registered modules won't work. DDR4 is keyed differently from DDR3, so a DDR3 module can't be installed by mistake. Speed depends on the CPU, not the chipset: Core i5 and i7 configurations run DDR4-2666, while Celeron, Pentium and i3 configurations run DDR4-2400. Faster modules such as DDR4-3200 will work but simply clock down, so don't pay a premium for speed this machine can't use. Buying tip: for most people two matched 8 GB or 16 GB sticks (2 x 8 or 2 x 16) is the sweet spot — a matched pair also fills both slots while they're easy to reach.

Buying tips

• DDR4 SO-DIMM, 260-pin, 1.2 V, non-ECC, unbuffered — nothing else fits
• Max 2 x 16 GB = 32 GB; avoid 32 GB single modules
• 2666 MT/s for i5/i7 builds, 2400 MT/s for i3/Pentium/Celeron builds; 3200 MT/s sticks just downclock

Storage (SSD and HDD)

There are two storage spots, and you can use both at once. First, one M.2 slot that takes 2230 or 2280 drives and accepts both SATA and PCIe NVMe SSDs. The board's spec says the slot supports SATA and PCIe interfaces; Dell's documents don't quote the PCIe generation, but this is a Coffee Lake/Q370 platform, so an NVMe drive runs at PCIe 3.0 x4. It's held in place by a single M2x3.5 screw into the system board. Second, one 2.5-inch SATA bay (SATA 6 Gb/s) for an SSD or hard drive, up to 7 mm tall — whether a 9.5 mm drive fits isn't confirmed, so plan on 7 mm. The bay and the M.2 slot can be populated together, which is the ideal setup: a fast M.2 NVMe SSD for the operating system and a 2.5-inch SATA SSD or HDD for bulk storage. The M.2 slot takes SATA as well as NVMe drives, so check the protocol before you buy — SATA M.2 drives are much slower than NVMe ones and often cost similar money. Dell validates drives up to 1 TB (NVMe) and 2 TB (2.5-inch HDD); larger drives generally work but aren't on Dell's tested list. A separate M.2 2230 key E slot exists for the Wi-Fi module only, so don't try to put storage in it. This chassis has no 3.5-inch bays and no PCIe add-in card slots.

Buying tips

• Best boot drive: M.2 2280 NVMe SSD — confirm it's NVMe, not SATA
• Best bulk storage: 2.5-inch 7 mm SATA SSD or HDD in the drive bay
• M.2 + 2.5-inch can run together; bigger-than-1 TB NVMe usually works but isn't Dell-validated

Processor (CPU)

The CPU sits in a removable LGA 1151 socket on the Q370 board — it's not soldered, so it can be replaced. Dell's validated list is 8th-gen Coffee Lake T-series only: Pentium Gold G5400T and G5500T, Core i3-8100T and 8300T, Core i5-8400T, 8500T and 8600T, and the top of the range, the Core i7-8700T (6 cores, 12 threads). 9th-gen chips physically fit LGA 1151, but Dell never validated them for this machine's BIOS, so don't count on one working. One point of confusion to know about: Dell's spec sheet lists 65 W for every SKU, while Intel rates these T-series parts at 35 W. Dell's figure is best read as the cooling limit of the Micro chassis rather than the chip's TDP — either way, stick to 35 W T-series processors; regular 65 W desktop CPUs aren't validated for this tiny case. Update the BIOS to the latest version before you swap the processor. The upgraded CPU also determines your memory speed (2666 vs 2400), so a CPU change can affect RAM performance too.

Buying tips

• Only 8th-gen T-series are validated: Pentium Gold G5400T/G5500T, i3-8100T/8300T, i5-8400T/8500T/8600T, i7-8700T
• Skip 9th-gen and non-T 65 W desktop chips — not validated here
• Update the BIOS first

How to upgrade

Before you start

• Safe, general outline for any of the upgrades below.
• Back up anything you can't afford to lose — especially before a storage swap or CPU change.
• Shut the machine down fully and unplug the power cable and any peripherals.
• Ground yourself (touch the metal chassis or use an anti-static strap) before handling parts.
• Open the case. The exact clips, latches and screws vary by step, so follow the owner's manual for your chassis when opening it — see the references below.
• Install the part: seat memory modules firmly until the side clips engage, secure M.2 drives with the M2x3.5 screw into the board, and for a CPU change follow the socket's installation marking rather than forcing anything.
• Close the case and reconnect the power.
• Switch on and check the BIOS/firmware that the new part is recognised before you trust it — then let the operating system see it too.

Good to know

• Dell's documents don't quote the M.2 slot's PCIe generation; the platform supports PCIe 3.0 x4.
• Dell lists 65 W for all validated CPUs while Intel rates those T-series parts at 35 W — Dell's figure reflects the chassis cooling limit.
• A 9.5 mm-tall 2.5-inch drive in the single bay isn't confirmed; plan on 7 mm.

Frequently asked questions

How much RAM can the OptiPlex 5060 Micro take?

32 GB maximum, as two 16 GB DDR4 SO-DIMMs. Each slot tops out at 16 GB — 32 GB single modules are not supported.

Does it support NVMe SSDs?

Yes. The single M.2 slot accepts both SATA and PCIe NVMe drives in 2230 or 2280 length. The platform supports PCIe 3.0 x4, though Dell doesn't quote the generation in its documents.

Can I upgrade the CPU to an i7?

Yes — the Core i7-8700T is the fastest processor on Dell's validated list for this machine. It's a 35 W T-series chip, which is what the Micro chassis is built for.

Does it support 9th-gen processors?

Not officially. 9th-gen parts physically fit the LGA 1151 socket, but Dell never validated them in the 5060 Micro's BIOS. Don't buy one expecting it to work.

Does it support ECC memory?

No. Only non-ECC, unbuffered DDR4 SO-DIMMs (260-pin, 1.2 V) are supported.

Can I use the M.2 slot and a 2.5-inch drive at the same time?

Yes. Dell's storage combinations include M.2 SSD plus 2.5-inch HDD configurations, so both can be populated together — a great way to get a fast boot drive and cheap bulk storage.
