Memory (RAM)

The Micro has two user-accessible SO-DIMM slots, and no memory is soldered down, so both slots can be filled or replaced. It takes DDR4 SO-DIMM modules, non-ECC and unbuffered only — ECC or registered modules are not supported. The ceiling is 16 GB per module and 32 GB in total (2 × 16 GB), which is the validated maximum; bigger modules are not supported here.

Dell recommends 2666 MT/s DDR4, and mixing speeds does work — the memory simply runs at the speed of the slowest module. One quirk to plan around: all Core i3 models (8100/8300 and their T variants) run memory at 2400 MT/s, so in an i3 machine faster RAM will be underclocked anyway. If you have an i5 or i7, 2666 MT/s modules make sense; if you have an i3, 2400 MT/s modules do the same job.

Conseils d'achat

• Buy 2 × 16 GB DDR4 SO-DIMMs if you want the maximum 32 GB — that is as far as the Micro goes
• Get non-ECC, unbuffered modules only
• Match speeds across both modules; 2666 MT/s is the recommended spec

Storage

You have three places to put storage, but only one true M.2 drive socket. It accepts either a 2230 or a 2280 module, in either SATA AHCI or PCIe 3.0 x4 NVMe flavour, and Dell caps it at 2 TB. Both kinds of M.2 SSD work; because PCIe 3.0 x4 is the ceiling, a top-end PCIe 4.0 drive gains nothing here. The second M.2 socket inside the case is occupied by the Wi-Fi/Bluetooth card and cannot be used for a drive — so you can't run two M.2 SSDs.

For extra space there is a 2.5-inch SATA bay, but it is a slim (7 mm) bay and it needs Dell's own internal bracket and cable. On used or refurbished units that hardware is often missing, so check before buying a drive for it. Dell officially caps the bay at 2 TB as well. Larger 2.5-inch drives sometimes work, but many 4 TB models are 15 mm thick and simply won't fit.

Valid combinations are an M.2 drive on its own, a 2.5-inch drive on its own, or the M.2 as the boot drive with a 2.5-inch drive for bulk storage. A 16 GB Intel Optane M.2 cache module is also supported, though that technology is largely obsolete today. There are no PCIe expansion slots on the Micro at all. Some units have an SD card reader at the front, but that was optional and varies by region and configuration — check the machine you're buying.

Conseils d'achat

• For the biggest speed gain, boot from an NVMe M.2 2280 SSD of up to 2 TB
• Want a second drive? Budget for a slim 7 mm 2.5-inch SATA drive and confirm the Dell bracket and cable are included
• Don't buy a second M.2 SSD expecting to plug it in — that socket is the WLAN card

Processor (CPU)

Unlike most small-form machines, the CPU here is socketed and replaceable. Dell documents the socket as LGA 1151 (Coffee Lake); you may see this generation of socket listed elsewhere as LGA1151v2. The supported list is 8th Gen Intel only: Core i3-8100/8300, i5-8400/8500/8600 and i7-8700, their 35 W T variants, plus Celeron G4900T and Pentium G5400T.

9th Gen processors (an i9-9900, for example) are not supported, even though they share the socket — Dell never certified them for the 7060 and the BIOS and microcode don't cover them. The processor is cooled in a tiny case, so the thermal limit is 65 W. Note the power adapter too: 65 W CPUs call for the 130 W supply, while a system with the 90 W brick is limited to the 35 W T-series chips. If you're upgrading a T-series machine to a full 65 W chip, you may need the bigger adapter as well.

There's no discrete graphics in the Micro — it relies on the processor's Intel UHD 630 integrated graphics.

Conseils d'achat

• An i7-8700 (or 8700T for the coolest, quietest setup) is the top upgrade Dell validates
• Only consider 8th Gen Coffee Lake chips; skip 9th Gen parts no matter how well they seem to match
• Check your power brick wattage before buying a 65 W CPU

Comment mettre à niveau

Avant de commencer

• Back up anything you care about before opening the case.
• Shut down the machine, switch it off and unplug the power adapter and all cables.
• Ground yourself to avoid static damage — touch the metal chassis or use an anti-static strap.
• Open the case following Dell's owner's manual or service manual for the exact disassembly steps for this model; don't force clips or covers.
• Install the new part, close the case, reconnect the power and start up.
• Check in the BIOS/firmware setup that the new memory, drive or processor is recognised before booting into your operating system. For a CPU change, make sure you are on a BIOS revision that supports it — 9th Gen chips won't be recognised whatever you do.

Étapes

1. Installing memory
   Fit DDR4 SO-DIMMs in the two available slots, aligning the notch and pressing evenly until the side clips click. Fill both slots with matched modules for the best result, staying at 16 GB per module.
2. Installing an M.2 SSD
   Fit a 2230 or 2280 drive in the storage socket (SATA or NVMe), secure it as described in the service manual, then confirm the BIOS sees the drive before installing your operating system. The other M.2 socket belongs to the WLAN card and stays as it is.
3. Installing a 2.5-inch drive
   Mount a slim 7 mm SATA drive in Dell's internal carrier, connect the Dell bracket and cable, and tuck it into the bay. If the bracket and cable are missing, source them first — the drive won't fit or connect without them.
4. Replacing the processor
   Unlatch the socket, swap in a supported 8th Gen chip, re-apply the cooler correctly and check the BIOS reports it. Match the CPU to your power adapter: 65 W chips want the 130 W supply.

Bon à savoir

• Dell's documents for this machine are consistent on the numbers above. The one thing that varies is the optional front SD card reader: it appears on the family spec sheet, but it isn't documented per configuration, so check the individual unit.

Foire aux questions

How much RAM can the Dell OptiPlex 7060 Micro take?

32 GB maximum, in 2 × 16 GB DDR4 SO-DIMMs across the two slots. That is the validated ceiling for the Micro. Remember that the Tower and SFF versions of the 7060 go further — 64 GB over 4 DIMMs — so make sure you have the Micro before buying.

Does the OptiPlex 7060 Micro support NVMe SSDs?

Yes. Its single M.2 storage socket accepts either SATA or PCIe 3.0 x4 NVMe drives in 2230 or 2280 length, up to 2 TB according to Dell. The second M.2 slot is for the Wi-Fi card, so only one M.2 SSD can be installed.

Does the 7060 Micro support 9th Gen Intel CPUs?

No. The socket physically takes 8th Gen Coffee Lake processors, and Dell lists only those — up to the Core i7-8700 and its 35 W T variant. 9th Gen parts such as an i9-9900 are not supported: the BIOS and microcode don't recognise them.

Can I add a second SSD or a hard drive?

You can add one 2.5-inch SATA drive alongside an M.2 drive, but it must be a slim 7 mm model and it needs Dell's internal bracket and cable, which are often missing on used machines. Both the M.2 socket and the 2.5-inch bay are officially capped at 2 TB each.

Does the OptiPlex 7060 Micro support ECC memory?

No. Only non-ECC, unbuffered DDR4 SO-DIMMs work. ECC and registered modules are not supported.

What CPU upgrades are possible, and do I need a new power supply?

Any validated 8th Gen chip is fair game, from Celeron G4900T up to the Core i7-8700. A 65 W processor needs the 130 W power adapter; if your machine came with the 90 W brick, you're limited to the 35 W T-series processors.
