Rock-Solid Stability in All Conditions

ASRock ensures VRM stability for the Intel^® Xeon^® W-2400 and W-3400 series processors and DDR5 memory in all conditions and systems loads. Its leading VRM design introduces a 20+2 Power Phase with 90A SPS, Nichicon 12K Black Caps and server-grade power chokes built upon an ultra-low loss 14-layer PCB that prevents PCB bending and ensures signal integrity even under sustained extreme performance conditions.

Atop the VRMs sits a large aluminum fin array with three fans for active cooling, plus heatpipe and aluminum alloy heatsink over the rear IO that acts to further spread the heat. Users can also manually adjust the fan-speed curve in the BIOS to suit individual needs.

Ultimate Workstation Connectivity

Network connectivity includes two 10 GbE LAN (Marvell AQC113CS) ensuring file-transfers are superfast to networked or Cloud storage. One Intel^® I225LM (2.5 GbE LAN) with vPro provides Intel^® Active Management Technology and Intel^® Endpoint Management Assistant (Intel^® EMA), allowing trusted remote management for enterprise environments. In addition, Wi-Fi 6E with 2x2 antenna for connection reliability provides gigabit-class wireless networking, giving the convenience of high-speed, wire-free connectivity already built in.
