Dell OptiPlex 7050 Micro Upgrade Guide: RAM, SSD and CPU

Updated Oct. 8, 2026 · Written from this device's verified specifications

The OptiPlex 7050 Micro lets you upgrade its memory, storage and processor yourself. In short: up to 32 GB of DDR4 SODIMM RAM, one M.2 SSD slot plus one 2.5-inch drive bay, and a socketed 6th or 7th-gen Core CPU. For the CPU, a 35 W T-series part is the safe choice.

At a glance

  • RAM: 2 DDR4 SODIMM slots, up to 16 GB each and 32 GB total, non-ECC only
  • Storage: one M.2 NVMe slot and one 2.5-inch SATA bay; RAID is not supported
  • CPU: socketed 6th or 7th-gen Core i3/i5/i7 on the Q270 chipset
  • RAM speed depends on the CPU: 2133 MT/s with 6th-gen, 2400 MT/s with 7th-gen
  • No PCIe or card-reader slots are documented for the Micro

RAM: up to 32 GB of DDR4 SODIMM

The Micro has two SODIMM slots and takes ordinary non-ECC unbuffered DDR4 SODIMMs in 4, 8 or 16 GB sizes. The most you can install is 32 GB (2 x 16 GB). Dell's documents mention no soldered memory, so both slots are yours to fill.

Install a matched pair to get dual-channel operation. Speed depends on your processor: 6th-gen CPUs run memory at 2133 MT/s and 7th-gen CPUs at 2400 MT/s. Faster modules in a 6th-gen system will simply run at 2133.

Buying tips

  • Buy DDR4 SODIMM (laptop-size) modules, not full-size desktop DIMMs
  • Choose non-ECC, unbuffered modules
  • Buy two identical modules, such as 2 x 8 GB or 2 x 16 GB, for dual-channel
  • 2400 MT/s modules are fine; with a 6th-gen CPU they run at 2133 MT/s

Storage: one M.2 slot and one 2.5-inch bay

The M.2 slot is listed for 2280 (22 x 80 mm) PCIe NVMe Gen3 x4 SSDs. Dell's manual shows 256 GB and up to 512 GB drives, but those are the configurations Dell offers. Larger NVMe drives likely work, though Dell doesn't confirm it. Dell's family spec sheet also hints at 2242 length support and M.2 SATA drives, but that is unconfirmed for the Micro, so stick with a 2280 NVMe SSD if you want a sure fit. A separate M.2 slot is for the WLAN card only, not storage.

The 2.5-inch SATA bay is listed for HDDs up to 2 TB (5400 RPM) and 7 mm SATA SSDs. Dell gives no maximum height for hard drives, so check thickness before buying. RAID is not supported.

Dell's manual also lists a 3.5-inch 7200 RPM drive for the Micro. That entry looks like a copy from the larger Tower/SFF models, since the Micro has just one 2.5-inch bay. Don't plan on fitting a 3.5-inch drive. If you use Intel Optane memory, it occupies the single M.2 SSD slot, so you can't combine it with an M.2 NVMe SSD.

Buying tips

  • For the M.2 slot, look for an M.2 2280 PCIe NVMe SSD
  • For the 2.5-inch bay, a 7 mm SATA SSD is the documented fit
  • Check the thickness of any 2.5-inch hard drive before buying
  • Don't count on RAID or a second M.2 storage drive

CPU: 6th and 7th-gen Core only

The processor is socketed, so it can be swapped. Dell lists 6th-gen (Skylake) and 7th-gen (Kaby Lake) Core i3, i5 and i7 chips on the Q270 chipset. Dell's documents don't name the socket; these CPUs use LGA1151.

Listed 6th-gen parts: i3-6100/6100T, i5-6400T/6500/6500T/6600/6600T and i7-6700/6700T. Listed 7th-gen parts: i3-7100/7100T/7300T, i5-7400T/7500/7500T/7600/7600T and i7-7700/7700T. Moving from a 6th-gen to a 7th-gen chip also lifts RAM speed from 2133 to 2400 MT/s.

Dell's spec sheet says up to 65 W for the OptiPlex 7050 family, and the Micro list includes some 65 W parts. But the Micro is a small chassis that is normally built for 35 W T-series chips, and Dell's documents don't cover its cooling or power limits. Treat 65 W CPUs as unverified here and choose a 35 W T-series part for safety.

Buying tips

  • Buy only a CPU from Dell's 6th/7th-gen list for this model
  • Prefer 35 W T-series parts such as i5-7500T or i7-7700T
  • Newer-generation desktop CPUs will not work on this board
  • A 7th-gen chip also gives you 2400 MT/s memory support

How to upgrade

Before you start

  • Back up your important files before opening the computer
  • Note which CPU generation you have, since it sets your RAM speed and affects which CPUs make sense
  • Have your Dell owner's manual for the OptiPlex 7050 Micro open for the exact disassembly steps
  • Work on a clean, flat, static-safe surface and keep small screws in a dish

Steps

  1. Back up and shut down
    Save your data, then shut Windows down fully (not sleep or hibernate).
  2. Unplug everything
    Disconnect the power cable and all other cables and peripherals. Hold the power button for a few seconds to drain leftover charge.
  3. Ground yourself
    Touch bare metal on the chassis or wear an anti-static wrist strap before handling any parts. Hold components by their edges.
  4. Open the case
    Follow the owner's manual to remove the cover and any parts that block access to the component you are changing.
  5. Install the new part
    Fit the SODIMMs, the M.2 SSD, the 2.5-inch drive or the CPU as shown in the manual. Seat parts firmly and don't force anything. Remember that the M.2 slot for storage is separate from the WLAN M.2 slot.
  6. Close up and reconnect
    Refit any parts you removed, put the cover back on, then reconnect the power cable and peripherals.
  7. Check that the system sees the part
    Start the computer and enter the BIOS/firmware setup screen. Confirm the new memory total, drive or processor is listed. For a new drive, you will still need to install or restore an operating system or format it in Windows.

Good to know

  • Dell's documents don't name the CPU socket; these CPUs use LGA1151.
  • 65 W CPUs are unverified in the Micro chassis, and Dell doesn't document cooling or power limits for higher-wattage swaps.
  • Dell's Micro manual lists SSDs up to 512 GB while the family spec sheet says up to 1 TB. These are Dell configurations, not confirmed physical limits.
  • Dell's family spec sheet hints at M.2 2242 and M.2 SATA support, but the Micro manual lists only 2280 PCIe NVMe, so treat the others as unconfirmed.
  • Dell's manual lists a 3.5-inch hard drive for the Micro, but the Micro has only one 2.5-inch bay, so that entry is probably an error.
  • No maximum height is documented for 2.5-inch hard drives; only 7 mm SSDs are listed.
  • Intel Optane needs a 7th-gen or newer CPU, Windows 10 64-bit and Intel RST 15.2 or later, and it uses the only M.2 SSD slot.
  • No PCIe, card-reader or other expansion slots are documented for the Micro.

Frequently asked questions

How much RAM can the OptiPlex 7050 Micro take?

Up to 32 GB, as two 16 GB DDR4 SODIMMs. Each slot accepts 4, 8 or 16 GB modules.

Does the OptiPlex 7050 Micro support ECC memory?

No. Use non-ECC unbuffered DDR4 SODIMMs.

Why is my RAM running at 2133 instead of 2400?

With a 6th-gen CPU, memory runs at 2133 MT/s. Only 7th-gen CPUs run it at 2400 MT/s.

Can I add an NVMe SSD to the OptiPlex 7050 Micro?

Yes. There is one M.2 slot listed for 2280 PCIe NVMe Gen3 x4 SSDs. Dell shows drives up to 512 GB, though larger ones likely work. The separate M.2 slot is for the WLAN card only.

Can I use both an M.2 SSD and a 2.5-inch drive?

Yes. The M.2 slot and the single 2.5-inch SATA bay can be used together. RAID is not supported. Intel Optane memory would take the M.2 slot, so it can't be combined with an M.2 SSD.

Which CPUs can I upgrade to, and can I fit a 65 W one?

Dell lists 6th and 7th-gen Core i3, i5 and i7 chips, including 35 W T-series and some 65 W parts. The Micro chassis is normally built for 35 W T-series CPUs, and 65 W use is unverified, so a T-series chip is the safer choice.
