Today we are looking at some new laptop memory by Kingston that takes advantage of some late-specs for Sandybridge chipsets: 1600 and 1866 memory support. These modules are Plug N Play for i7 Gen 2 systems, tho they should be backwards compatible for earlier systems. For systems using integrated Intel graphic solutions, the gaming perks are quite noticeable. Since the GPU uses system RAM for video, the added speed can generate up to 80% in FPS increases. YMMV.
But we are interested if this DDR3-1866 stuff is good for systems with dedicated graphic solutions. So to start off, I ripped open a G73SW-A1 and swapped out the DDR3-1333 stuff and upgraded the system to 16GB. (With this much ram, you can kill the pagefile unless you are doing some really intensive video or CAD, or unless you already upgraded to a SSD.)
Just on raw thruput, the system gets a nice performance boost:
and Windows Index tops off:
And for 3DMark results: (1333/1866)
I would have to say the big surprise was the 3DMark11 scores... seems the tests benefit from transfer speeds
Part II will have some real world FPS tests, and Part III will involve testing the older JH/JW series.
