DDR2 Memory: Enhanced Performance Profiles (EPP)

SLI Certified Memory for the nForce 590 SLI chipset will feature EPP and Corsair was the first to market with these EPP-based DIMMs. Corsair was one of the companies that took off and ran with Enhanced Performance Profiles as their customer base is enthusiast oriented. Other memory companies like Kingston and OCZ have been working with NVIDIA on EPP modules and when the upcoming AMD AM2 processors come out will be ready to support EPP.
