PDP Systems, who sells memory modules under Patriot brand-name, said it would mark its “Extreme Performance” DDR2 products based on their potential overclockability, underlining overclocking potential DDR2 SDRAM memory has and guarantying significant performance enhancement for customers.

“We felt the name change not only helped communicate the superior performance of our DDR2 +XBL line to the gaming/performance community, but was necessary to properly note the PCB revisions. We could have added a revision to the end of the original 4200+XBL, but we felt changing the name would ultimately create less confusion,” stated Garrett Rezzonico, Director of Marketing.

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.

Currently the world’s highest performing commercially available memory modules are 667MHz DDR2 products. The most popular memory brands – Corsair Memory, Crucial Technology, GEIL, Kingston and OCZ Technology Group – offer 667MHz devices with relatively aggressive latencies: CL4 4-4-12, CL 4-4-10, CL4 4-4-12, CL4 4-4-10 and CL4 2-2-8 respectively. With the speeds of up to 700MHz and latency settings of CL4 3-3-12, Patriot ships the world’s highest-performance memory modules.

In mid-January, 2005, Kingston said it would launch DDR2 SDRAM products rated to operate at 750MHz and demonstrated DDR2 at 866MHz. But so far the company has not commercially released its new products.

Patriot’s memory modules come with aluminum heat-spreaders and lifetime warranty. Pricing may vary depending on the retailer.
