Yes it was advertized to give better performance! That was the reason I bought it!
The new OCZ PC2-8500 SLI-Ready Series is equipped with NVIDIA Enhanced Performance Profiles (EPP) to optimize the modules' performance on nForce® SLI-based motherboards. OCZ exclusively engineered select high-performance modules with advanced SPD (Serial Presence Detect) settings to allow compatible motherboards to recognize and utilize the added information, ultimately increasing the performance potential of the entire platform.
OCZ SLI-Ready memory modules are programmed to boot at 1066MHz DDR2 with supremely fast timings of 5-5-5. Only motherboards equipped with the custom-designed BIOS, such as those designed for NVIDIA nForce SLI MCPs, can detect the optimized SPD profiles and ensure the memory functions under the best possible conditions. The exclusive OCZ SPD specifications take out the guesswork and provide enthusiasts and gamers with significant overclocked performance with no manual adjustment or compatibility issues.
Each OCZ SLI-Ready module comes equipped with an exclusive NVIDIA XTC heatspreaders for the most efficient heat dissipation and a look that stands out like its performance. Additionally, all SLI-Ready memory is backed with toll-free technical support, the exclusive EVP (Extended Voltage Protection) coverage, and an industry leading Lifetime Warranty.
With the fusion of the sophisticated EPP memory specification and cutting-edge, high-speed OCZ DDR2 architecture, the PC2-8500 edition is the ultimate breakthrough for advanced SLI platform performance.
And all this was and is pure BS! I could not get 1066MHz hell it was hard to get 800MHz stable! I was so PISSED OFF!
