The ASUS PRIME B840-PLUS WIFI, model 90MB1IZ0-M0EAY0, is an ATX motherboard built around the AMD B840 chipset and Socket AM5 platform. It supports compatible AMD Ryzen 7000, Ryzen 8000 and Ryzen 9000 Series processors, with capacity for one processor. Designed for systems requiring current-generation memory, storage, networking and peripheral connectivity, it combines DDR5 support, PCI Express expansion, multiple M.2 and SATA storage connections, integrated networking, wireless connectivity and high-definition audio in a 30.5 cm by 24.4 cm ATX format.
Four 288-pin DIMM slots provide support for as much as 192 GB of DDR5 SDRAM. The memory subsystem uses a dual-channel architecture and supports unbuffered memory with non-ECC, on-die ECC and ECC integrity-checking capabilities. A bus clock of up to 3800 MHz when overclocked is specified, while AMD EXPO technology and ASUS Enhanced Memory Profile, or AEMP, are also supported. ASUS OptiMem II is incorporated among the board's hardware features for its memory implementation.
Expansion is provided through one PCIe 4.0 x16 slot and two PCIe 3.0 x1 slots, alongside the four DIMM slots and CPU socket. Storage can be connected through four SATA-600 ports and three M.2 sockets. One M.2 socket accepts 2242, 2260 and 2280 M.2 Key M devices, while the other two M.2 Key M sockets support the 2280 form factor. Two of the M.2 connections use PCIe 4.0 and support RAID 0, RAID 1 and RAID 10, while an additional PCIe 4.0 M.2 connection is provided. The four 7-pin Serial ATA connectors likewise support RAID 0, RAID 1 and RAID 10.
A broad selection of external connections allows the motherboard to accommodate displays, peripherals, networking equipment and audio devices.
