Notes

Note 1: Turbo describes the available frequency bins (+133 MHz) of Intel Turbo Boost Technology that are available for 4, 3, 2, 1 active cores respectively. (see Intel Turbo Boost for a more detailed explanation)
Note 2: Mobile Core i7 processors officially support 1 SO-DIMM for both DDR3 channels. This, however, is exceeded in the Asus G51J, HP Envy 15, Dell Precision M6500, and Lenovo ThinkPad W510, all of which contain 4 SO-DIMM slots.
