15R Special Edition (7520) Memory types.

Hi everyone,

I have a 15R SE 7520; 3rd gen i5, 4GB DDR3 RAM (Make : Hynix), Win 8.1 SL.

I want to upgrade memory to 8GB.

I want to know if I can use the existing 4GB DDR3 alongwith a new 4GB DDR3L RAM? It seems that DDR3 RAMs are not easily available nowadays. I specifically zeroed in on the following product:

RE: 15R Special Edition (7520) Memory types.

First:  ensure your current 4G is one module.  More likely, the system shipped with 2X2.

Second:  skip all "Value" RAM (Kingston KVR, Corsair "Value Select", etc.).  It's generally sloppy-tolerance, cheap memory.

Third:  don't mix DDR3 with DDR3L.  The exception:  there are dual-voltage modules that can run at both 1.35 and 1.5V (Crucial generally sells these).

You likely need a pair of 4G modules -- not just one 4G unit.
