Patriot Memory for Ultrabook - Scaling SODIMM RAM Density vs. Battery Life
Last month we reviewed Patriot's low voltage SODIMM 'Memory for Ultrabook' RAM and found it increased notebook battery life over standard 1.5v SODIMM memory. We're back now to answer the question we left with last month - what happens to battery performance when I use more than one stick of memory?

Lenovo W530 - Mobile Workstation



It's important to remember that our Lenovo W530 isn't designed for long battery life. This is a mobile workstation unit with a beefy NVIDIA Quadro GPU and real processing power at the heart of the unit. When we chose the W530 for power testing, we wants to find a product that would emulate two types of readers, gamers and our business readers. At the time the W530 also simulates mainstream users with older notebooks that have batteries that aren't in the best condition.


Our Lenovo W530 uses a 6-cell battery to decrease the length of the MobileMark 2012 test. A common upgrade for mobile professionals is the upgraded 9-cell battery. Since we are worried more about comparing two (or more) products to each other in comparison, the comparison difference is of more value than the raw number on its own.




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 draws 1.5 volts. The Patriot Memory for Ultrabook doubles the stock density, 8GB, retains the same speed, 1600MHz and uses just 1.35 volts. Today we're going to scale the RAM by stick density. This will also scale the density of RAM, 8GB to 16GB then to 32GB while moving from 1 stick to 4 sticks.




Like many mobile workstation notebooks, the W530 has four slots for SODIMMs. These are paired into twos, one under the keyboard and one under a cover on the bottom.
