The Patriot’s Extreme Performance and Dual-Channel DDR2 4200+XBL series are being renamed to 5600+XBL, reflecting maximum memory throughput when overclocked. While the memory modules come with SPD programmed as PC2-4200 (533MHz) with CL3 2-2-4 timings, the speed may be set to PC2-5300 (667MHz) with CL4 3-3-10 latency settings or even PC2-5600 (700MHz) with CL4 3-3-12 timings. The company claims that memory modules will function well with 1.8v – 2.0v voltage setting.More info at X-bit Labs
