Matching modules are always to be found in Kingston on the website of the manufacturer and function, as well as those in the Fujitsu Celsius i7-3770, always perfectly straight. I sit for years in Kingston and have never had to take the extended warranty of 10 years to complete. In Celsius they are working together with the 2 * 2GB modules from the manufacturer, or 20 GB for fast working in Adobe Lightroom and Photoshop.
