ATX board with PCIe 5.0 M.2 and 2.5Gb LAN

The ATX form factor fits standard chassis and provides four DDR5 slots, a PCIe 4.0 x16 graphics slot and one PCIe 5.0 M.2 socket for fast storage. Rear I/O includes WIFI 6E, 2.5Gb Ethernet, USB 10Gbps Type-C and a Thunderbolt 4 header for front-panel expansion. VRM, M.2 and PCH heatsinks plus hybrid fan headers handled by Fan Xpert 2+ keep thermals in check.

192 GB DDR5 ceiling and 5.5 GHz boost headroom

Four 288-pin slots accept up to 192 GB of dual-channel DDR5 at speeds up to 7600 MT/s when overclocked. The included 8-core, 16-thread CPU reaches a 5.5 GHz max boost clock, delivering 100+ FPS in popular titles. Memory support steps down through 5000 MT/s, giving wide compatibility headroom before the 192 GB limit is reached.

Questions about this item

How much DDR5 memory can the board address before the 192 GB ceiling stops further upgrades?

The four 288-pin slots support up to 192 GB of DDR5, running dual-channel at speeds from 5000 to 7600 MT/s depending on the modules installed.

What thermal and acoustic load should I expect from the VRM and chipset heatsinks during an all-day compile or render?

The VRM heatsink, M.2 heatsink and PCH heatsink work with hybrid fan headers and Fan Xpert 2+ to keep component temperatures in check under sustained multi-core loads.

Which storage drives and add-in cards must I already own to populate the board's primary interfaces?

You need DDR5 modules, SATA 6 Gbps drives for the four SATA ports, a PCIe 4.0 x16 graphics card for the top slot, and M.2 SSDs for the PCIe 5.0 and additional M.2 sockets.
