upgrade memory
Hi
I I have Dell Inspiron 15R 5520 it has come with a memory Hynix 4GB As shown in the picture
And I want to add a new 4GB memory to be 8GB
I searched in amazon for the same type
And I found two, but they don't match in the last two numbers. I've marked the part in red that doesn't match
My questions
What does this last part of the numbers mean?
And if I buy one, it will be identical to the old memory and will work without problems?

Almost all details r mentioned by U2CAMEB4ME. That PBC 203V means it will cary the power supply upto that voltage. Basically u need to check the RAM Type & memory which ur laptop supports. as it similarly works as motherboard & has voltage, clock speed, data handling & more as mentioned by U2CAMEB4ME. @U2CAMEB4ME - please help understanding if wrong.1870
