Bit Tech had an interview with EVGA's Shamino to discuss the company's dual-Xeon SR-2 motherboard, you can check it out over here.
BT: Dual socket boards aren't usually associated with overclocking, going more for reliability, and that's what traditional brands such as Tyan and Supermicro have built a reputation for. Why would someone buy your SR-2 over one of their products?
Shamino: Because of the fact that we can overclock and pump all this extra voltage and frequency into the CPUs should mean that it's better at handling stock frequencies. It's got more overhead built in, with higher quality components so it should last longer under heavy use. I don’t think reliability and overclocking are at loggerheads, it all depends on the working environment.
