Lifecycle and support

Memory (RAM)

Four full-size DDR5 DIMM slots, dual-channel, up to 192 GB in total. DDR5 only: DDR4 and older modules have a different key notch and physically won't fit. The slots take un-buffered desktop DIMMs; registered or buffered server memory (RDIMM/LRDIMM) is not supported and won't boot. Un-buffered ECC and non-ECC modules both work, though this board isn't validated like a proper server platform.\n\nHow much can you fit? The current ASUS spec page states 192 GB, which implies 48 GB modules. The 2022 owner's manual listed 128 GB using 4 x 32 GB modules. The two documents disagree here, so if you need more than 128 GB, plan on 48 GB modules and a current BIOS version.\n\nOn speed, the documents disagree too: the spec page lists up to DDR5-8000 (OC) with newer BIOS versions, while the manual topped out at DDR5-6400 (OC). Rated speeds are overclocked figures and depend heavily on your CPU and modules. AMD's sweet spot on this platform is DDR5-6000, which keeps the memory controller at a 1:1 FCLK ratio. EXPO and XMP-class overclocking profiles are supported.\n\nPopulation rules matter. One module goes in DIMM_A2; two modules go in A2 + B2 (the second and fourth slots from the CPU), not the two closest ones. Filling all four uses every slot. Mixed sizes are allowed, but dual-channel operation maps to the smaller channel, and any extra capacity runs single-channel. Modules should share the same CAS latency, and same vendor/version kits are recommended. Check the memory QVL on the ASUS support page for your BIOS version.\n\nBuying tip: for a two-stick kit, match it to the QVL and don't chase the highest rated speed — DDR5-6000 is the sensible target for Ryzen 7000. If you want more than 128 GB, buy 48 GB modules and update the BIOS first.

Buying tips

• DDR5 un-buffered desktop DIMMs only — no DDR4, no RDIMM/LRDIMM
• Two sticks: A2 + B2 slots, not the two nearest the CPU
• Over 128 GB needs 48 GB modules and a current BIOS
• Check the ASUS QVL; DDR5-6000 is the sweet spot for Ryzen 7000

Storage (M.2 SSDs and SATA drives)

You get four M.2 slots plus four SATA 6 Gb/s ports, so there's plenty of room for a bigger SSD. M.2 takes 2242, 2260 and 2280 drives in most slots.\n\nM.2_1 is the fast one: PCIe 5.0 x4 NVMe, taking 2242/2260/2280 drives. Put your fastest drive here.\n\nM.2_2 is the odd one out: PCIe 3.0 x4 or SATA, and the only slot that accepts the longer 22110 format. It's also the only slot that takes a SATA M.2 drive.\n\nM.2_3 and M.2_4 are PCIe 4.0 x4 NVMe, taking 2242/2260/2280 drives.\n\nThe thing to watch: a PCIe drive installed in M.2_2 disables SATA ports 1 and 2. A SATA M.2 drive in that slot keeps them alive. If you still use spinning disks or SATA SSDs, plan your drive layout around this.\n\nAll four M.2 slots come with heatsinks, and the larger sink on M.2_1 suits the heat of a Gen5 drive — though a hot PCIe 5.0 drive still benefits from good case airflow. Drive bays and thickness limits for 2.5-inch and 3.5-inch drives come from your case, not the motherboard. ASUS states no per-drive capacity ceiling, so in practice you're limited by the drives you can buy. For redundancy, AMD RAIDXpert2 supports NVMe and SATA RAID 0, 1 and 10.\n\nBuying tip: a PCIe 5.0 SSD only makes sense as your main drive in M.2_1; for extra bulk storage, PCIe 4.0 drives in M.2_3 or M.2_4 are the cost-effective choice, and SATA drives cost you two ports if you use M.2_2 in PCIe mode.

Buying tips

• M.2_1: PCIe 5.0 x4 — best for your boot drive
• M.2_2: only 22110 slot and only SATA M.2 slot; PCIe mode kills SATA ports 1 and 2
• M.2_3 and M.2_4: PCIe 4.0 x4 — good value for extra capacity
• 2.5-inch/3.5-inch bay limits come from your case, not the board

Processor (CPU)

The board has Socket AM5 (LGA1718), so the CPU is replaceable. It supports AMD Ryzen 7000, 8000G and 9000 series desktop processors. Ryzen 7000 works out of the box; the 8000 and 9000 series arrived later and need a BIOS update — the 2022 manual only listed Ryzen 7000. This board has BIOS FlashBack, so you can update the firmware before installing a newer chip. Check the CPU support list at asus.com for your model and BIOS version.\n\nASUS doesn't document a maximum CPU wattage on the spec pages. The AM5/X670 platform officially handles the 170 W desktop SKUs, so the full desktop lineup is usable provided the VRMs get adequate cooling and case airflow — treat that wattage figure as general platform knowledge rather than something stated in ASUS's documents.\n\nOne caveat on Ryzen 8000 APUs: they cut the primary PCIe slot down to x8 or x4 and change how some of the M.2 lanes behave. If you're choosing between a Ryzen 8000G and a standard Ryzen 7000/9000, factor that in.\n\nFinally, keep the PnP protective cap that covers the socket. ASUS requires it for warranty returns and doesn't cover socket contact damage from an improper installation.\n\nBuying tip: update the BIOS to the latest version before you swap CPUs — it's the step people skip, and it's what makes newer chips work.

Buying tips

• AM5 (LGA1718): Ryzen 7000, 8000G and 9000 series
• Update BIOS first for 8000/9000 chips — this board has BIOS FlashBack
• Keep the socket's PnP cap; ASUS requires it for RMA
• Ryzen 8000 APUs run the primary PCIe slot at x8/x4

How to upgrade

Before you start

• Back up anything important before you open the case.
• Shut down, switch off at the PSU and unplug the mains cable.
• Ground yourself (touch the case or use an anti-static strap) before handling parts.
• Open the case and install the component. For RAM, use A2 + B2 for a two-stick kit; for M.2 drives, use the slot that matches the drive's speed and length; for the CPU, follow the socket instructions carefully and keep the PnP cap.
• For exact disassembly, screw locations and torque details, use the ASUS owner's manual for this board.
• Close the case, reconnect the power and boot into the BIOS to confirm it detects the new memory, drive or processor, and check the BIOS version if you've just fitted a newer CPU.

Steps

1. Back up
   Save anything you can't afford to lose before you touch the hardware.
2. Power down
   Shut down, switch the PSU off and unplug the mains cable.
3. Ground yourself
   Discharge static by touching the case, or use an anti-static strap.
4. Open the case and install
   Fit the part in the right slot or socket. The ASUS owner's manual covers the exact disassembly, screw locations and socket handling for this board.
5. Close up and boot
   Reconnect the power and start the machine.
6. Check the BIOS
   Confirm the BIOS shows the new RAM, drive or CPU, and check the firmware version if you installed a newer processor.

Good to know

• Documents differ on maximum RAM (128 GB in the 2022 manual vs 192 GB on the current spec page) and on top memory speed (DDR5-6400 OC vs DDR5-8000 OC).
• No exact CPU wattage ceiling is published by ASUS for this board.

Frequently asked questions

How much RAM can the ASUS TUF GAMING X670E-PLUS WIFI take?

The current spec page says 192 GB across four DDR5 slots, which implies 48 GB modules. The 2022 manual listed 128 GB (4 x 32 GB), so the documents disagree. Above 128 GB, use 48 GB modules and a current BIOS.

Does it support DDR4 or registered ECC memory?

No. It's DDR5 only, un-buffered DIMMs. Un-buffered ECC and non-ECC both work, but RDIMM/LRDIMM server modules are not supported and won't fit or boot.

Which M.2 slot is fastest?

M.2_1, which is PCIe 5.0 x4. M.2_3 and M.2_4 are PCIe 4.0 x4, and M.2_2 is PCIe 3.0 x4 or SATA — and it's the only slot that takes 22110 drives and SATA M.2 drives.

Does an M.2 SSD disable any SATA ports?

Yes, in one case: a PCIe drive in M.2_2 disables SATA ports 1 and 2. A SATA M.2 drive in that slot keeps those ports working.

Which CPUs does it support, and do I need a BIOS update?

Ryzen 7000, 8000G and 9000 series on Socket AM5. Ryzen 7000 works from the start; the newer series need a BIOS update. The board supports BIOS FlashBack, so you can update before installing the new chip.

Do I lose anything by using a Ryzen 8000G APU?

Yes. With Ryzen 8000 APUs the primary PCIe slot runs at x8 or x4 instead of x16, and some M.2 slots behave differently because of the reduced CPU PCIe lanes.
