Excellent product
Ordered to install on Lenovo Thinkpad T510 but finally installed on ACER Aspire 7730 because the Thinkpad did not support 1600Mhz. As a result, the Acer chipset (2 x 4GB - DDR 1333Mhz) was moved to the Lenovo, and the Corsair Vengeance's landed in the Acer. In the end, both machines appreciate this upgrade.
