OCZ has increased its nVidia SLI-Ready product line with the launch of DDR2-1000 (PC2-8000) memory modules optimized specifically for nVidia chipsets. These modules work at 1,000 MHz, have 5-4-4-15 timings at 2.1 V and are available in 2 GB modules and 4 GB kits. Also, they support EPP (Enhanced Performance Profiles) technology that allows memory modules negotiate with memory controller betters timings and the higher clock under which they can work in order to achieve the best performance. This technology works only with nVidia chipsets.
