Corsair Vengeance Low Profile DDR3 PC12800/1600MHz CL9 2x4GB

Perfect for when you need high performance and low clearance.
Choose from 1.5V and 1.35V Models
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.

Low-profile heat spreaders
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.

Great for overclocking
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. Add Vengeance to your XMP-compatible system and it can automatically select the maximum possible overclocking performance, quickly and easily.
