Crucial 16GB Kit (8GBx2) DDR3-1600 MT/s (PC3-12800) 204-Pin SODIMM Notebook Memory CT2KIT102464BF160B / CT2CP102464BF160B (Personal Computers)

   I installed this in my wife's MacBook Pro (mid 2012; non-retina; MacBookPro 9,2) . Very easy upgrade. No issues. Memory instantaneously recognized, no need for 'option command r p'. At the same time, I upgraded the HDD to Samsung 850 EVO 500GB (http://www.amazon.com/Samsung-2-5-Inch-Internal-MZ-75E500B-AM/dp/B00OBRE5UE/ref=cm_cr_pr_product_top). With these 2 upgrades (and a fresh OS X 10.10 install) the computer is better than the day we bought it. Very highly recommended for Mac users. Another note: even though Apple claims 8GB being maximum amount of memory for this Mac, it can actually take 16 GB. I entertained that idea for a moment, but at this point 16 GB is a bit pricey. Very happy with the upgrade. amznJQ.onReady('jQuery', function() { amznJQ.available('popover', function() { var widgetDom = jQuery("#RKDWLAN4I4SG6_imageSection_7B22F7E6-C60D-11E5-8BA5-FFE640C7709F"); var images = widgetDom.find(".review-image-thumbnail"); for (var c=0;c

I purchased the Crucial CT2K8G3S160BM 2x8GB to increase the memory in my Lenovo Y410P laptop from 8-GB to 16-GB. My Y410P has two memory slots, and one slot was already occupied by a factory-installed Samsung M471B1G73QH0-YK0 8-GB memory card. I probably could have just added another 8-GB card. But to avoid any possible memory glitches, I prefer not to mix-and-match memory cards of different types. The existing Samsung memory was PC3L/DDR3L, with the 'L' signifying that it is low-voltage 1.35V memory, whereas the standard PC3/DDR3 memory uses a higher voltage of 1.50V. You should not combine memory of different voltages or use memory with incorrect voltage since your laptop may not even boot up. To further maximize compatibility with my laptop, since it came equipped with CL11 1600-MHz memory, I likewise wanted to stick with CL11 CAS Latency speed, instead of going for memory with a faster (lower) CL rating. Some CL9 memory cards have faster specifications, but I really think...Read more
