This page explains everything you need to know about Intel's GM965 Express family of chipsets, encompassing the real GL960, the falsely advertised GL960, GLE960, GM965, GME965 and PM965 mobile chipsets for the Santa Rosa and Santa Rosa Refresh platforms.

Introducing the Intel GM965 Express Family, Codenamed 'Crestline'

When Intel's brand new Intel Core2 processor debuted for the laptop and embedded markets, it brought with it a new family of chipsets. Known by their codename as Crestline, the new chipsets provided much anticipated features — front-side bus support for up to 800 MT/s, better system memory support, and arguably the most important of the time, a much needed upgrade in the graphics department, courtesy of Intel's Graphics Media Accelerator X3100; a slight variant of the desktop version, the X3000. It was Intel's first integrated graphics solution supporting the unified shader design, that has been brought forward ever since. The PM965 chipset lacks integrated graphics and is intended to be paired with laptop-class graphics cards from AMD and NVIDIA.

Crestline was officially unveiled in May 2007, under the new marketing moniker of "Intel GM965 Express Chipset Family." The GM965 family consists of three main chipset tiers — GL960 for low-end, GM965 for mainstream, and PM965 for high-end. There are also two embedded versions of the low-end and mainstream chipsets; GLE960, and GME965. Feature-wise, the embedded models are identical to the laptop counterparts.

The next section will compare the three laptop chipsets, as Intel has marketed them.

  • Note 1 — Processors with a 1067 MT/s front-side bus aren't compatible.
  • Note 2 — Core2 Extreme support is limited to X7800, X7900 and X9000 models only.
  • Note 3 — Some users have reported up to 8 GB of system memory working in specific laptop models.
  • Note 4 — DDR2-800 system memory modules will be underclocked to 667 MT/s due to chipset limitation.
  • Note 5 — Memory bandwidth is directly affected by the system memory configuration.
  • Note 6 — GMA X3100 frequencies are directly affected by the system memory configuration.
