Lenovo W530 - Mobile Workstation
It's important to remember that our Lenovo W530 isn't designed to be a long life notebook with 10+ hours on the portable juice. We use this system to test SSD performance in our standard SSD reviews. Since we review more SSDs than any other publication in the world, online or in print, we often need to run two and three drives in a single day. To reduce the number of hours in our notebook test we use a lower capacity 6-cell battery instead of a 9-cell battery. We also only run the notebook with moderate power savings in the BIOS settings. Even with these settings we can achieve nearly 300 minutes of use on a single charge depending on what SSD we have in the notebook.
Our Lenovo W530 shipped with a single stick of DDR3 RAM running at 1600MHz. The base system ships with 4GB of RAM and that's what we normally use to test with. The stock RAM uses 1.5V.
The Patriot Memory for Ultrabook doubles the stock density, 8GB, retains the same speed, 1600MHz and uses the new lower power setting, 1.35V. Going into the review I wasn't sure if the Patriot 1.35V SODIMM would outperform the Lenovo stock SODIMM since it doubles the density, but those fears have been sidelined.

MobileMark 2012 1.5 is an application-based benchmark that reflects usage patterns of business users in the areas of office productivity, media creation and media consumption. Unlike benchmarks that only measure battery life, MobileMark 2012 measures battery life and performance simultaneously, showing how well a system design addresses the inherent tradeoffs between performance and power management.
Getting right down to business, we have our results. The Patriot Memory for Ultrabook stick running just 1.35 volts gave us a measurable battery life increase. The stock Lenovo RAM delivered 266 minutes of battery life and the Patriot Memory for Ultrabook delivered 283 minutes. The Memory for Ultrabook improved our battery life by 17 minutes in our configuration.
We want to point out that if we configured the W530 to extend the battery life as far as it could, the time difference would be much further apart. With a 9-cell battery, a common upgrade for notebook users and all of the power saving features enabled the battery life would increase, nearly double and the difference between these two memory sticks would nearly double as well.
