8GB kit for 15-inch MBP
Apple has begun selling an official 8GB RAM upgrade kit, designed for the latest 15-inch unibody MacBook Pro. The kit contains two 4GB 1066MHz DDR3 SO-DIMMs, and costs $1,200. It is only being offered for 2.66 and 2.93GHz MacBook Pros though, not the low-end 2.4GHz model. It is unknown if the RAM might be compatible with the previous mid-range, clocked at 2.53GHz.
The kit doubles the amount of memory a 15-inch Pro can use, but may not be the most cost-effective means of upgrading a system. Many in the public have complained that official Apple RAM is more expensive than equivalent memory from third-party manufacturers; equivalent PC expansion kits are often several hundred dollars less. The new 8GB option does however bring the 15-inch Pro in line with its 17-inch sibling.
