From DRAMeXchange's testing results, despite the difference in the speed or brand of the memory, they share several common characteristics.


1. There is a significant performance boost when the DRAM content increases from 512MB to 1GB.


2. When the content is 2GB (1GBx2pcs), Dual Channel performs better than Single channel.


3. The performance enhancements are more evident when DDR2 667 MHz is upgraded to DDR2 800 MHz, than when DDR2 800 MHz is upgraded to DDR2 1066 MHz/1050 MHz.


4. No connections are seen between the DRAM content and the 3DMark06 testing results. 


The main highlight of this test was to understand how the different memory sizes would affect the PC efficiency when running Windows Vista. If Office 2007 is also installed, a serious lag is experienced when the memory content is only 512MB. When the content increases to 1GB, evident improvements are seen, but system lags still exist. By increasing the memory size to 2GB, only occasional lags occur when running the PowerPoint or Excel programs.


From DRAMeXchange's testing results, we can conclude that-- "No matter the type of CPU or motherboard (under the premise that the CPU and M/B are compatible with the Vista capable standard) you choose, two 1GB UDIMM modules with Dual Channel and a US$150 discrete VGA card are required"


DRAMeXchange estimates that 50% of the newer DT/NB shipment will include a memory content of 1GB for 1Q07. 2GB content will account roughly 10~12% in 1Q07.  As the penetration rate of Windows Vista and Office 2007 is expected to gradually increase, the commodity DRAM and discrete Graphic card demand will also grow as well.


Appendix. The Dual Channel


Dual Channel technology is a type of technology that controls and manages the system's memory. Theoretically, the bandwidth in the data transmissions will double when two memory modules of the same spec. are employed. In other words, the performance of 2 512MB UDIMM modules with Dual Channel will be better than 1GB UDIMM (1memory module can not take advantage of the Dual Channel feature). If you want to utilize the Dual Channel function, DRAMeXchange suggest choosing two memory modules with the same spec and content. Insert them as a pair in the same color slot on the motherboard. (Please follow the motherboard user guide for a more detailed installation guide).
