Summary: I purchased this ram for a samsung ativ book 4 with an intel i5 3230m and this ram performed at the exact stated specs. I get 9-9-9-24 1t with this and it definitely made an improvement over my 8gb samsung ram rated at 11-11-11-28 2t.
Pros: For me the biggest pro was the price. I lucked out and caught this on sale so I got a good deal on it. The performance is another big plus for this item.
Summary: When it comes to laptop ram I always purchase the same thing. Corsair Vengeance DDR3 or DDR3L 1600mhz. I have yet to receive a bad stick of this ram. I have probably bought 40 sticks of this ram throughout my life. Always a solid choice.
Pros: Made by Corsair 1600 mhz Timings @ 9/9/9/24 DDR3L @ 1.35V
Summary: Product is reliable, low profile, 1600 MHz with 9-9-9-24. They work warm. Bigger cooler is unnecessary for this product. I had 8 GB of this ram since 2010. Made it 16 GB with these. Corsair RAMs are solid.
Summary: My sister's motherboard refuses to allow me to set the clock speed to exactly 1600MHz... it would either go higher or lower by a factor of 100 after restart... so I just set it to auto and hope for the best.
Pros: - no errors in memtest - works great as expected - love the blue colored heatsinks - love that awesome lifetime warranty
