In general you want to avoid 2 things when it comes to fast RAM on a system like this:
1. Single rank.
2. X16 chips.
This will be listed as 2RX8. Single rank and X16 chips are both cheaper to produce and usually show up in OEM laptops. You can look up a more detailed explanations online about dual rank and X8 chips but in short, both allow more memory operations to happen simultaneously instead of sequentially. The kit I listed above also runs at 3200 CL20 (lower is better) where most JDEDC kits will run at 3200 CL22.
