Help me choose a New DDR3 RAM

[Guest]

Help me choose a perfect ram for my PC. Here is my specs
Processor : Intel G2030
Motherboard : Asus H61M-CS
RAM : Dynet 4GB DDR3 1333Mhz
HDD : Toshiba 500GB

Now I'm planing to add 4GB more to my pc. But i heard somewhere that not all the rams works with each other. But i couldn't find Dynet Rams beacause it is not on sale these days. Help me choose another 1333Mhz 4GB DDR3 RAM from Flipkart, Amazon etc.

Update :
Here is my CPUZ results https://drive.google.com/file/d/1skJmUpgtLChS-3I0Rs2-JiuLqi65xLdR/view?usp=drivesdk

You could check specs of the memory modules either written on it or with CPUZ software (under memory tab), and match them in the new 4GB ram you're intending to buy.

The Dynet ram you have is available at alibaba and ebay. Of course you can buy any other make or model as long it has the same 1333MHz resresh rate. Still compatibility can not be guaranteed, so before buying ask about the return policy of the shop!
