Although DDR SDRAM has become considerably cheaper, two largest mainboard manufacturers, ASUS and MSI, keep being quite conservative towards this memory type. They believe that the share of DDR mainboards in their production will hardly exceed 20% by the end of this quarter.
In a way they explain it by the fact that the use of DDR SDRAM instead of PC133 SDRAM provides a very small performance increase. Besides, PC133 memory is currently very popular in the OEM market. Moreover, the upcoming price drop on Intel Pentium 4 based systems with RDRAM will undoubtedly tell on the popularity of DDR SDRAM, and this influence will be not that positive, as you can imagine.
However, it may be in Q3 already that Pentium 4 processor acquires DDR SDRAM support. and as for the small increase in performance, it can be cured if you don’t use any ALi chipsets. In this case the performance gain will no longer seem too small or even negative (like in case of Aladdin Pro5)...
