Intel SR2EU: The Ultimate Dual-Socket LGA 1366 Enthusiast Motherboard

For PC enthusiasts and hardcore builders, few motherboards command as much reverence and awe as the Intel Skulltrail SR2EU. Designed during an era when extreme performance was the ultimate pursuit, this motherboard remains a legendary piece of hardware, embodying a level of ambition rarely seen in consumer-grade components. It wasn’t just a motherboard; it was a statement—a platform built for those who refused to accept limits.

The most defining feature of the SR2EU is its dual LGA 1366 sockets, which support not just one, but two Intel Nehalem or Westmere-based Xeon processors. This allowed users to combine two top-tier CPUs like the Xeon X5680—creating a 12-core, 24-thread computing behemoth years before such core counts became common in mainstream platforms. For content creators, video editors, and early adopters of heavy multi-threading, the SR2EU was nothing short of a revolution.

But raw processing power was only part of the story. The SR2EU also featured a highly unusual and flexible multi-GPU support structure. It came equipped with four PCI Express x16 slots—supporting both NVIDIA SLI and AMD CrossFire technologies simultaneously. This was a landmark achievement at the time, effectively ending the “GPU faction wars” by letting users mix and match or max out graphics configurations without vendor lock-in. It was, and in some ways still is, the ultimate playground for GPU enthusiasts.

The board also reflected its workstation-grade DNA with seven DDR3 memory slots per CPU, totaling 14 slots and supporting up to 128GB of triple-channel RAM. This massive memory capacity was almost unheard of in the enthusiast space and underlined the board’s purpose: uncompromising performance.

Of course, such capability came with demands. The SR2EU required an Extended ATX case and a high-wattage power supply with dual 8-pin EPS connectors. It generated significant heat and came with a premium price tag. Yet, for those who built on it, the experience was unparalleled. This was a platform meant for breaking records, rendering massive projects, and dominating benchmarks.

Even today, the Intel SR2EU maintains a cult following. It represents an era of fearless engineering—a time when Intel targeted the most demanding users with a product that blurred the line between desktop and server. Modern platforms may offer more efficiency and newer features, but few carry the same aura of extreme possibility.
