Vengeance Low Profile heat spreaders have a reduced height of 1.03 (26.25mm). They're designed for high-performance systems with extra-large CPU coolers, small form factor system builds, or any other space-constrained application where standard Vengeance memory might not fit. 1.5V Vengeance Low Profile DDR3 memory is designed to meet the memory specification of the 2nd Generation Intel Core processor family. The Special Edition Arctic White Vengeance Low Profile memory modules operate at the ultra-low voltage of 1.35V, for ultra-quiet systems and other low-voltage applications. Vengeance Low Profile heat spreaders have a reduced height of 1.03 (26.25mm). They're designed for high-performance systems with extra-large CPU coolers, small form factor system builds, or any other space-constrained application where standard Vengeance memory might not fit. Each Vengeance memory module is built from DRAM ICs specially selected for performance potential, to allow you to explore the limits of system overclocking. If you're new to overclocking, full support for Intel Extreme Memory Profile (Intel XMP) makes it easy.
