Introduction
Well folks, we're at it again! The previous reference build didn't meet our expectations, so we're trying again with a completely different setup.
This time around, we'll focus less on the hardware compatibilities regarding setup and such, as there are plenty of SR-2 reference sources to be had around the web. Instead, we'll focus on the fun stuff, like lots of pictures and how to get the best ppd possible.
Our
As always, the other DC teams are welcome to request any tests or benchmarks for their associated clients, and we'll be happy to oblige. We're all one big happy OCF family, right?
Latest News
- The recent (first half of Oct 2010) lack of availability of the SR-2 was due to a packaging change. 270-WS-W555-A1, no longer available/in stock, comes with the ECP v3 in the box. The 270-WS-W555-A2 does not come with the ECP v3 in the box. (See this post in this thread by an EVGA Product Manager)
