I popped the battery, removed 3 screws, and in seconds had swapped the top 2GB module for the OWC module. OWC shipped me a 4GB and 2GB module for evaluation, but at first I installed just the 4GB module-my MacBook Pro 2.4GHz (2007 model) had two 2GB modules already installed. Unfortunately the runtime was only a bit more than two hours, see the results. It also speaks well to the rock solid reliability of the OWC memory kit. Amazing performance and a big improvement over the previous models, which could become uncomfortably hot. The MBP17 was rock solid, and only got moderately warm on the bottom or top. ThatвЂ™s 100% CPU usage of both cores, fast graphics enabled, continuous hard-drive access and the screen on full brightness. Using the OWC 8GB kit (two 4GB modules), I ran the MemoryTester stress test for 5.6 hours at an ambient temperature of approximately 70вЏ (21вЊ). Price-conscious users might want to try 6GB first to see if it meets their needs without going to 8GB.

You can install 6GB or 8GB in the 17' MacBook Pro as 2GB + 4GB or 4GB + 4GB. The 2.4GHz model supports a maximum of 6GB.

Update, April 2009: the newest 15' 2.66GHz and 2.93GHz also support 8GB. This kit has now been used extensively in the review of the 17' model-itвЂ™s rock solid and highly recommended! Get the 8GB kit at OWC. The 2009 17' MacBook Pro accepts 8GB memory (two 4GB modules). The bulk of the review that follows was written for the 6GB kit, but applies equally to the 8GB kit for the MacBook Pro 17' (see review). When running multiple program together, such as Photoshop, Aperture, a RAW-file converter, Mail, Safari, etc, the extra 2GB can make a very large difference in performance, well beyond the apparently modest increase in memory. So having a 6GB module is more akin to having 62% more available memory.

This is a big deal, as 6GB is in actuality more than 2GB more than 4GB! The usable memory on a 4GB system is around 3.2GB after booting, vs 5.2GB on a 6GB system.
