¹ Lakeport chipsets lacks support for remapping memory; the size of addressable memory space may be less than 4GB, regardless whether the processor operates in 64-bit mode.

• 915P (Grantsdale)
  • Supports Pentium 4 on an 800 MHz bus. Uses DDR memory up to 400 MHz, or DDR2 at 533 MHz. Replaces AGP and CSA with PCI Express, and also supports "Matrix RAID", a RAID mode designed to allow the usage of RAID levels 0 and 1 simultaneously with two hard drives. (Normally RAID1+0 would have required four hard drives)
  • Sub-versions:
    • 915PL - Cut-down version of 915P with no support for DDR2 and only supporting 2GB of memory.
• 915G (Grantsdale-G)
  • 915P with an integrated GMA 900. The core is compliant with Vertex and Pixel shader versions 2.0, and has similar functionality to GeForce FX 5200 64bit and Radeon 9100 IGP, though it does not have Transform & Lighting (T&L) features.
  • Sub-versions:
    • 915GL - Same feature reductions as 915PL, but supports 4GB of memory. No support for external graphics cards.
    • 915GV - Same as 915G, but has no way of adding an external graphics card.
    • 910GL - No support for external graphics cards or 800 MHz bus.
• 925X (Alderwood)
  • Higher end version of 915. Supports another PAT-like mode and ECC memory, and exclusively uses DDR-II RAM.
  • Sub-versions:
    • 925XE - Supports a 1066 MHz bus.
• 945P (Lakeport)
  • Update on 915P, with support for Serial ATA II, RAID mode 5, an improved memory controller with support for DDR-II at 667 MHz and additional PCI-Express lanes. Support for DDR-I is dropped. Formal dual-core support was added to this chipset.
  • Sub-versions:
    • 945PL - No support for 1066 MHz bus, only supports 2GB of memory.
• 945G (Lakeport-G)
  • A version of the 945P that has a GMA 950 integrated , supports a 1066 MHz bus.
  • Sub-versions:
    • 945GZ - Same feature reductions as 945PL but with an integrated . No support for external graphics cards.
• 955X (Glenwood)
  • Update for 925X, with additional features of "Lakeport" eg. PAT features and ECC memory, and uses DDR2.
