When multitasking computer slows. Would upgrading memory help with this?
Noticed some are CL 11, CL 9. Which best for this computer?
i5-4200M at 2.50 GHZ
Would G.Skills Ripjaws -DDR3L 1600 (PC3L 12800); CAS Latency 9: 1.35V; Dual Channel Kit

The lesser the CL, the better the system performs. The Gskill will work fine.

However not all can support CL9, so CL11 standard is usually the safest bet:
