Review: perfect for Proxmox build - I bought this to replace my aging Proxmox system that was built on hardware from 2014. The new system has only been online for about a month so far, but this board has served me well and met all my expectations.
Review: Solid Motherboard - Just installed this with a Core Ultra 7 265k. This board is heavy and feels well constructed. The only issue I had was the LED bar at the bottom stays powered 24/7, it can be turned off with Asrock's RGB software though. The VRM heatsinks also blocked my Nzxt X53 cooler from being installed in its usual orientation. Overall a solid product from ASRock. No issues with stability or performance so far. Hopefully it lasts for years to come like the Msi board it relaced.

### ⭐⭐⭐⭐⭐ Works fine in D213 2U Istar, has what we need for our NVR build.
*by J***E on July 10, 2025*

Use this board in an NVR build that we do using a D213 Istar chassis. Works fine, no issues. Like the Dual network ports, saves having to add a card. Good value for price point. Well laid out, and fits well within chassis.
