Hello, I, unfortunately, do not understand gland, resulting in the following complexity. I had to purchase the RAM for your ASUS x555lf. It stood on 4 turned out to be soldered. The choice fell on the Kingston SODIMM [KVR16S11/8] 8 GB. Put (exactly right ), and the laptop can not see it in the BIOS about it is not the word. Checked on the laptop of a friend - just working. I tried to insert the other 2, same story: the laptop does not see it. Updated BIOS - 0. With all this, Speccy, CPUID CPU-Z info for the RAM see. Advise me what to do, please what could be wrong with the laptop?
