Gigabyte B650 AORUS ELITE AX Upgrade Guide: RAM, SSD, CPU

Updated Oct. 9, 2026 · Written from this device's verified specifications

This guide covers adding memory, storage or a faster processor to the Gigabyte B650 AORUS ELITE AX, including the ICE and AX V2 versions. In short: it takes DDR5 only, three NVMe M.2 SSDs and four SATA drives, and Ryzen 7000, 8000G and 9000 chips on socket AM5, though a BIOS update may be needed first.

At a glance

  • Four DDR5 DIMM sockets, up to 256 GB total with 64 GB modules on a recent BIOS
  • Memory is rated at 5200 MT/s in the manual; faster kits run as overclocks and aren't guaranteed
  • Three M.2 slots for NVMe SSDs only (2280 or 22110), plus four SATA ports
  • Socket AM5 takes Ryzen 7000, 8000G and 9000; Ryzen 8000 needs BIOS F20 or later, Ryzen 9000 F31 or later
  • Q-Flash Plus can update the BIOS without a CPU installed

Memory (RAM) upgrades

The board has four full-size DDR5 DIMM sockets (DDR5_A1, A2, B1, B2) running in dual channel. It takes non-ECC unbuffered DIMMs only, so don't buy registered or ECC-registered memory. Gigabyte's documents list DIMM sockets only, so laptop-style SO-DIMMs won't fit. All memory sits in these four sockets.

Capacity depends on the document you read. Newer manuals and Gigabyte's web pages list 64 GB per module and 256 GB in total. An older manual lists 48 GB per module and 192 GB in total. The higher figure likely needs a recent BIOS, so update before fitting 64 GB modules.

Speed is also described two ways. The manual rates memory at 5200, 4800 and 4400 MT/s. Gigabyte's web spec page lists faster speeds up to 8000 MT/s, but marks them as overclocked (OC). Treat anything above 5200 MT/s as not guaranteed. AMD EXPO and Intel XMP profiles are supported. The CPU and memory combination can also limit speed, module count and supported types.

Buying tips

  • Buy DDR5 non-ECC unbuffered DIMMs only
  • Two modules are the simplest dual-channel setup; four-module setups typically run slower than two
  • Fit the first module in the DDR5_A2 socket
  • Check Gigabyte's memory support list for the exact kit before buying a fast one
  • For 64 GB modules, plan on updating the BIOS first

Storage upgrades (M.2 SSDs and SATA drives)

There are three M.2 M-key slots for NVMe SSDs, all taking 2280 or 22110 lengths: M2A_CPU, M2B_CPU and M2C_SB. M2A_CPU runs at PCIe 5.0 with Ryzen 7000 or 9000 CPUs, but only PCIe 4.0 with Ryzen 8000. M2B_CPU is PCIe 4.0, limited to x2 with Ryzen 8000 "Phoenix 2" chips. M2C_SB connects through the chipset at PCIe 4.0. Only M.2 PCIe SSDs work in these slots; M.2 SATA SSDs are not supported. Check the manual if you want to fit a shorter M.2 drive.

For 2.5-inch or 3.5-inch drives there are four SATA 6Gb/s ports (SATA3 0 to 3). How many drives you can mount depends on your case's bays and your cables. RAID 0, 1 and 10 are supported for NVMe and SATA devices, but an M.2 PCIe SSD can't be combined with a SATA drive in one RAID set.

Gigabyte's documents we found don't state a per-drive capacity limit. They also don't say whether M.2 and SATA ports share bandwidth, so check the full manual if you plan to fill every port. The main PCIe x16 slot can also hold an NVMe SSD on an adapter card.

Buying tips

  • Buy an NVMe (PCIe) M.2 SSD, not an M.2 SATA one
  • Put a PCIe 5.0 SSD in M2A_CPU, and only if you run a Ryzen 7000 or 9000 CPU
  • Match the SSD length (2280 or 22110) to the slot
  • Check your case has free 2.5-inch or 3.5-inch bays before buying SATA drives

CPU upgrades

The board has one AMD Socket AM5 and the AMD B650 chipset. The processor is socketed, so it can be replaced. Gigabyte lists Ryzen 7000, Ryzen 8000G and Ryzen 9000 support. One note: the ICE marketing page lists only 7000 and 8000, while its spec page and the manual include 9000.

A BIOS update may be needed before a newer chip will boot. Ryzen 8000 needs BIOS F20 or later, and Ryzen 9000 needs F31 or later. Gigabyte's changelog suggests older boards need an update for Ryzen 9000 but doesn't state a minimum outright. Q-Flash Plus lets you flash the BIOS without a CPU, memory or graphics card installed. Gigabyte warns that flashing carries some risk and shouldn't be done if your current version works fine.

Check Gigabyte's CPU support list for the specific chip before buying. Ryzen 8000 APUs also reduce the main PCIe x16 slot to x8 (Phoenix 1) or x4 (Phoenix 2). Gigabyte's pages don't state a maximum CPU TDP, so check the support list and your cooler and power supply for high-power chips.

Buying tips

  • Look up the exact CPU on Gigabyte's support list and note the minimum BIOS
  • Ryzen 7000 and 9000 keep the main slot at PCIe 4.0 x16
  • Update the BIOS with Q-Flash Plus before swapping in a Ryzen 9000 chip if your board is on an older version
  • Make sure your cooler fits socket AM5

How to upgrade

Before you start

  • Check which BIOS version your board is running, and update it first if you're moving to Ryzen 8000 or 9000.
  • Back up important files before changing storage or flashing the BIOS.
  • Check the CPU, memory and SSD against Gigabyte's support lists.
  • The ICE, AX V2 and Elite V2 versions share one manual, so use it for exact layouts and screw positions.
  • Have a clean, static-free work surface.

Steps

  1. Back up and update
    Back up your data. If you're fitting a Ryzen 8000 or 9000 CPU, update the BIOS first, using Q-Flash Plus if the board won't boot with the new chip.
  2. Power off and unplug
    Shut down the PC, switch off the power supply and unplug the power cable and other cables.
  3. Ground yourself
    Touch bare metal on the case or use an anti-static strap before handling parts, and hold components by their edges.
  4. Open the case
    Remove the side panel. For exact disassembly and the position of the sockets and screws, follow the owner's manual.
  5. Install the part
    For memory, fit the first module in DDR5_A2 and press until the clips lock. For an SSD, use an NVMe-capable M.2 slot (M2A_CPU, M2B_CPU or M2C_SB) or connect a SATA drive to one of the SATA3 0 to 3 ports. For a CPU, follow the manual's socket AM5 and cooler instructions.
  6. Close up and reconnect
    Refit the side panel, reconnect the cables and power on.
  7. Check the BIOS
    Enter the BIOS at startup and confirm it shows the new memory capacity, drive or CPU. If it doesn't, power off, unplug and reseat the part, and re-check BIOS compatibility.

Good to know

  • Memory capacity figures differ between Gigabyte's older and newer documents (192 GB versus 256 GB); the higher figure likely needs a recent BIOS.
  • Memory above 5200 MT/s is listed as overclocked and isn't guaranteed.
  • Gigabyte's documents don't confirm whether M.2 and SATA ports share bandwidth; check the full manual.
  • The manual's exact DIMM population table for two-module setups isn't reproduced here; check it for the correct slots.
  • The minimum BIOS for specific Ryzen chips isn't listed here; use Gigabyte's CPU support list.
  • Gigabyte's pages don't state a maximum CPU power rating.
  • The Elite V2 name appears without 'AX' in the shared manual, which may mean no Wi-Fi, but this isn't confirmed.

Frequently asked questions

How much RAM can the B650 AORUS ELITE AX take?

Newer Gigabyte documents list up to 256 GB across four DDR5 sockets, using 64 GB modules. An older manual lists 192 GB with 48 GB modules. The higher figure likely needs a recent BIOS.

What RAM speed does the B650 AORUS ELITE AX support?

The manual rates DDR5 at 5200, 4800 and 4400 MT/s. Gigabyte's web page lists speeds up to 8000 MT/s, but these are overclocked and not guaranteed. EXPO and XMP profiles are supported.

Does the B650 AORUS ELITE AX support PCIe 5.0 SSDs?

Yes, in the M2A_CPU slot with a Ryzen 7000 or 9000 CPU. With Ryzen 8000 that slot runs at PCIe 4.0, and the other two M.2 slots are PCIe 4.0.

Can I use an M.2 SATA SSD?

No. The M.2 slots support PCIe (NVMe) SSDs only. SATA drives go on the four SATA ports.

Does it support Ryzen 9000?

Yes, but you may need a BIOS update first. Gigabyte lists Ryzen 9000 support from BIOS F31 onward. Q-Flash Plus can update the BIOS without a CPU installed.

Does it work with Ryzen 8000G processors?

Yes, with BIOS F20 or later. The main PCIe x16 slot drops to x8 or x4 with these APUs, and Phoenix 2 chips limit M2B_CPU to x2.
