Suitable RAM for z50-70


Right off the assembly line

I own a Lenovo z50-70 series laptop. I currently have an 8GB RAM and I am planning to upgrade it to 16 Gb by adding another 8GB RAM. I am currently looking at possible RAMs that i can use with my existing pre installed RAM as I have read that to get the best performance it is better to add a RAM of the same manufacturer and configuration.

This is my existing RAM I am using
Samsung 8GB 2Rx8 PC3L - 12800S - 11 - 13 - F3. 471B1G73QH0-YK0. Similar to the one below
Samsung 8GB DDR3 Laptop Memory RAM 2Rx8 PC3L-12800S-11-13-F3 M471B1G73QH0-YK0 6023927791657 | eBay

Since I am residing in India, I cannot purchase the above RAM hence have to look for alternatives.

When i checked on lenovo parts lookup they provided me this Hyn HMT41GS6AFR8A-PB DDR3L 1600 8GB

Which of the below RAMs are compatible with the one above?
Kingston 8GB 204-Pin DDR3 SO-DIMM DDR3L 1600 (PC3L 12800) Laptop Memory Model KTD-L3CL/8G -
Sk Hynix 8gb 2rx8 Pc3l-12800s 1600mhz Laptop Ram Memory: Electronics
Samsung Laptop 8GB RAM M471B1G73QH0 YK0 DDR3L 1600 1600MHz PC3L 12800 | eBay.

The ebay one seems like the same one I have except it has a the number 11-12-F3 while my RAM is 11-13-F3. The Hynix RAM seems to have the same number as my RAM. I trust Kingston RAM hence I put it in the list above. I am confused now as what to buy.

Thanks for your help in advance

not to get the best performance but for better compatibility it is better to add a RAM of the same manufacturer, configuration and same batch if possible. That's why you will find dual channel ram kits which guarantees the rams are from same batch and will work flawlessly.

But rams and motherboards have tolerances to work with rams from different manufacturer and speed and latency. So rams from two different manufacturer mostly works with each other but it greatly depends on the motherboard and bios too. So it's better to get the ram of same manufacturer with same speed and latency if possible. So the samsung ram here is the best one you can go for.

Hynix has no proper after sales support here. Kingston is good but you've one existing samsung ram module so going with samsung ram module on ebay is the best choice here IMO. Also you can use lots of discount coupons to make the price even sweeter.
