Crucial and memorystock won't recognize my laptop's model

[salvatore247]

Hi, there! So, I bought my little brother an used Samsung laptop (NP-RC530-S02IT), a few days ago, and noticed it works good on it's 4gb of ram, however, since my brother wants to run the Dolphin Emulator and Cemu and etc., idk if 4gb would be enough.., so naturally we decided to try and upgrade the RAM.
Turns out most websites won't even recognize the laptop's model though.. I ran CPUZ and it said I have 2 slots 2x2gb manufacturer Samsung, DDR3, So-DIMM, PC3-8500F (533 MHz),1.50 Volts. Can u guys tell me where to look for an upgrade, cause I can't seem to find anything appropriate.
I wanna buy 1x4gb and mix it with the 2gb on the other slot,(yeah im aware it would run at the slower speed of the 2gb) or just buy 2x4gb.

The system specs are:

Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz (2.90 GHz with Turbo Boost)
NVIDIA GeForce GT 540M - 2GB
HDD 500GB SATA

CPUZ's exact ram specs are:
