Intel Goes DDR - Do We Really Care?

Behind The Silicon Curtain: Exclusive Test Of The P4/2666 With 533 MHz Rambus

Rambler's Top100 Рейтинг@Mail.ru


Краткое содержание статьи: Bending to industry pressure, Intel added DDR support for the 845 chipset - and the long desired alternative to RDRAM was born. Due to Intel's extensive experience in the chipset sector, most people will prefer the 845 chipset to other solutions, and its availability is also widespread. We put a total of 19 motherboards to the test in order to give you well-founded advice.

Intel's Strike Force:<BR>19 DDR-Motherboards With 845 Chipset and DDR-Support

Generally, ECC memory (error correcting code) is uninteresting for home use. These modules have 72 instead of 64 Bits and are able to correct single bit errors. From a hardware point of view, using this special memory ensures the best stability. But ECC has to be supported by both the chipset and the BIOS. Unfortunately, only 5 of the 19 tested motherboards support ECC, though the 845 chipset would support it. Just one more note: with ECC enabled, your performance will decrease by approximately 1% to 2% - if you want it, that's the price for maximum hardware stability.

For servers, this kind of memory is strongly recommended, as it contributes to optimum system availability. For home use, buying these modules is rather senseless, since typical Windows systems are stuffed with software and tend to be groggy anyway -- even more than the memory could ever be.

Intel chipsets still are considered to be reference products - both in terms of reliability and of technical features. All boards share the features that come with the chipset:

  • AGP 4x Interface
  • DDR memory controller for PC2100 (DDR266) *South Bridge resp. I/O Controller Hub 82801BA, including
    • UltraATA/100 IDE controller for 4 devices max.
    • two USB controllers with 2 ports each
    • LAN interface for easy attachment to 10/100 Mbit networks
    • AC97 controller for easy implementation of sound systems
    • CNR port for unexpensive expansion by a LAN/modem/sound riser card
    • 32 Bit PCI bus (max. 6 slots)
