Manufacturers often assign multiple product numbers to the same product. Strangely enough though, the reverse is not true. If Amazon is selling single sticks of name brand RAM with a specific manufacturer product number, when you buy two at the same time they should be exactly the same. In general, name brand RAM with different configurations will have different product numbers. I have ordered two single sticks before and they arrived as one high-density and one low-density. I bought the'matched set' to ensure both ram modules would be double-sided and low density. Sounds like the IT was feeding garbage to a technophobe. Lol at the apple support page comment haha.Дamaged swap space? Sounds bizarre because swap space is temporary and would not be used for saving files.Дamaged capacitors? Also sounds strange because the only way I know to fix a damaged capacitor is to replace it which requires a person that can perform board level repairs. I am sure the difference will be also known when one does photo or video editing, etc.

Save your money, and get something better.' Do not buy it, it is garbage, and its warranty service is garbage. I contacted manufacturer who wants me to ship it to USA from Geneva, costing somewhere along $100, at my charge. IT was able to repair the capacitors, but damaged sectors in SSD is gone for good. Further more, it damaged SWAP space in my SSD and a few capacitors in the motherboard. Upon arrival in London, laptop started failing, over in Geneva, my institute's IT was able to trace the defective RAM and took it out. I didn't have too much time to test it, and it seemed to work. 'I upgraded my laptop Lenovo T430 with this from 8gb to 12gb setup before going on an overseas work trip. I did see this one review though, and I am not sure how that happened: I think the RAM I have now is GSkill but I could be wrong haha. Definitely is cheaper than the Crucial one. They don't even have to be the same brand, just the same speed.

Never heard any complaints from the buyer too.ДЄny low-density (8 chips per side) 1600 ddr3L sodimm should work. Yes, it worked flawlessly for the month that I used it.
