Hi all. I bought 8gigs or DDR3-1333 ram ($20 after rebate) and was about to put it in because I still have the mentality from PC computers not having problem with using different speed and down clocking the ram, and noticed post on here on people stating to stick with DDR3 8500 because it is what Apple states should be used on the MacBook Pro. I wouldn't care what apple says, but then read that some people have had problems with the higher speed ram causing errors because the memory speed control is on the processor instead of a controller. Now, these postings are somewhat old, and someone out there must have put the higher ram on their computers since then with no problem Does anyone have any info on this? It's a shame that it will cost me $20 more to get the "correct" ram.
