Samsung and Microsoft have announced plans to jointly promote the green IT benefits which can be realised when Samsung's memory chips are combined with Microsoft's new operating system.

A meeting between Microsoft chief executive Steve Ballmer and Samsung Electronics chief executive Yoon-Woo Lee resulted in a decision to work together to encourage users to buy more environmentally friendly PCs.

The pair touted the energy savings that can be made when using Windows 7 and Samsung's 40nm-class DDR3 DRAM memory chips.

Samsung said that it will install Windows 7 on all of its corporate PCs worldwide, while Microsoft will promote the DDR3 memory chips to PC manufacturers.

"There is no doubt that the combination of Windows 7 and 40nm DDR3 in new PCs will make users very happy," said Dong-Soo Jun, executive senior vice president of memory marketing at Samsung Electronics.

"If you opt for 4GB of memory in a Windows 7-based system, over typical 2GB-based systems used today, you'll see an increase in performance, while using less power thanks to the efficiency of Samsung's 40nm DDR3 DRAM."

Samsung also hinted at further green IT efforts with Microsoft, saying that it will measure the effect of this and other collaborative efforts to examine the potential for other areas of global co-operation with Microsoft in IT development.
