Dual Channel Memory Architecture

ECC Memory (ECC mode) support varies by CPU.

* Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists).

Graphics

1 x HDMI™ 2.1 (4K@60Hz)
2 x Intel® Thunderbolt™ 4 ports (USB Type-C®) support DisplayPort 1.2/1.4 and Thunderbolt™ video outputs *

* Output at TBT4_E1 and TBT4_E2, the USB Type-C® ports right under RJ45 ports, each requires a USB-C to DisplayPort adapter cable. Graphics specifications may vary between CPU types.

** VGA resolution support depends on processors' or graphic cards' resolution. For more details about the video input and output settings please refer to the user manul.

Expansion Slots

2 x PCIe 4.0/3.0 x16 (x16, x8/x8)

AMD Ryzen™ 5000 Series/ 3000 Series Desktop Processors

2 x PCIe 4.0 x16 (x16 or dual x8)*

AMD RyzenTM 4000 G-Series Processor

2 x PCIe 3.0 x16 (x16 or dual x8)*

AMD B550 Chipset

1 x PCIe 3.0 x16 slot (supports x4 mode)**

2 x PCIe 3.0 x1 slots***

* Support PCIe bandwidth bifurcation for RAID on CPU function.

** PCIe 3.0 x4 will be switched from Thunderbolt™ 4 to PCIEX16_3 if the slot is populated; by then Thunderbolt™ 4 will have no output

*** These PCIe x1 slots share bandwidth with M.2_2, which runs at PCIe 3.0 x4 by default. You may go to BIOS setting to set M.2_2 to PCIe 3.0 x4 or x2 at will
