Windows 7 drives RAM capacity explosion; Vista SP2 usage rising

Windows 7 will drive the average PC RAM capacity to 4GB in the next 18 months. That's the conclusion of researchers at the exo.performance.network who are monitoring the ramp-up to Windows 7's launch on October 22. After evaluating data collected from early adopters of the Windows 7 RTM code spread across several hundred IT sites, the xpnet.com team observed that nearly 50 percent sported memory capacities of 4GB or higher, with some reaching as high as 12GB.

The average of all Windows 7 PCs was 3.7GB, which is in stark contrast to Windows XP PCs, where the average RAM capacity (for all versions) hovers at just under 1.7GB. Windows 7 RAM installations also best Vista's average of 2.7GB. In fact, the move from a Vista-centric world to one defined by Windows 7 will likely drive a jump in RAM capacity (by 33 percent) comparable to the one experienced during the transition from Windows XP to Vista (a jump of 37 percent in installed RAM).

The bottom line: While much has been made about Windows 7's supposedly reduced memory footprint, the reality is that a combination of Moore's Law (as it applies to RAM density) and the harsh lessons of the Vista debacle are prompting customers to err on the side of caution and equip Windows 7 PCs with ample RAM out of the gate.

Vista SP2 adoption risingThe adoption rate for Windows Vista Service Pack 2 ticked up a bit over the past few weeks. After lagging behind Service Pack 1 by a wide margin, SP2 is now gaining momentum, with nearly 20 percent of PCs reporting the newer service pack level. Meanwhile, the number of systems reporting SP1 installed dropped 2 percentage points (now 72 percent), as did the few laggards still running the Vista RTM release (now at just under 8 percent).
