I already have a Crucial memory part # CT51264BF160B.17FPD2. that is 4GB.
I ordered it from you to add to my Samsung RV511.
I would like to add 4GB more memory for a total of 8GB.
Your site list the memory as Crucial part # CT5300644.
My question is, will the CT5300644 be compatible with the CT51264BF160B.17FPD2 ?
Both part #'s have the same specs listed as 4GB DDR3L-1600 SODIMM 1.35V CL11.
Thank you for your question.
I have had a look in to this for you. CT5300644 and CT51264BF160B are actually the same memory. Both will work perfectly together in your RV511 model. You can see all the compatible memory upgrades for that model here: http://www.crucial.com/usa/en/compatible-upgrade-for//rv511
We do have a great support section of the website that you can see here: http://www.crucial.com/usa/en/support this includes installation guides for memory and SSD's.
If you do have any other questions at all, please don't hesitate to ask.
