Kingston 99U5471-050. A00LF, Serial Number 900F8143h (1132531600), DIMM DDR3-1600 SDRAM. I only thought about the "add-on" when it became necessary to simultaneously launch several professional programs and three browsers at the same time. And even then, it seems to be slower than a WD hard drive =) Pros below: For its size in 8Gb, it works clearly, for many years and without failures. With its cons. In the internet they write that with the standard it only holds 9cl instead of 11cl. According to the marking, the ignorant cannot find this plate at all (you need to look for kvr16ln11 / 8).
