These three graphs are the totals for Broken RAM by Chipset. Out of 304 Problem reports only 121 had RAM types listed. Some reports included two broken sticks of RAM which is not illustrated in these graphs. And lastly the other chipsets, Wintech, Kinston/Kingston, Kingston/MT, and ATP are not included.
This graph is the analysis of the speed for completion of lalapps power function using deferent RAM configurations.
All this data was collected from machines proven not to fall down over the course of 2 days.
