Late last week Team Group launched 3GB (3x1GB) and 6GB (3x2GB) capacity kits in DDR3-1333, DDR3-1600, and DDR3-1866 form. Team Group wasn't the first to offer tri-channel memory kits for Intel's new Core i7 platform, but for the time being, the company is claiming it has the "market-fastest" modules around
It's worth noting that at least one other memory company offers tri-channel memory rated at DDR3-1866. Corsair's high frequency kit lists the same latency timings and voltage requirement as Team Group's does, but this doesn't necessarily contradict the company's 'market-fastest' claim. Team Group's Xtreem DDR3-1866 memory does qualify as the highest frequency kits yet available, they're just not alone at the top.
Team Group, a company not as widely known in casual circles as some of the more commonly marketed brands, often targets the overclocking crowd. The company touts an extensive binning process on its high performance RAM, requiring that all modules pass a 24-hour burn-in test on "major overclocking motherboards from Asus and Gigabyte."
UPDATE 12/9/08So much for boasting the 'market-fastest' tri-channel kit. That distinction belongs to Kingston, who's tri-channel DDR3-2000 kit was released on October 29, 2008.
