What the Athlon X2 QL-65 is
The AMD Athlon X2 QL-65 is a 2.1 GHz mobile dual core from the late-2008 Griffin wave. It runs two Griffin cores at 2.1 GHz with no turbo, so 2 cores give 2 threads. Cache is 512 KB of L2 per core, 1 MB total, on a 65 nm process. Power is rated at 35 W on Socket S1.
The QL-65 shares its 2.1 GHz and 35 W rating with the QL-64, with no published specification difference between the two. Its HyperTransport link runs at 1800 MHz with a dual-channel DDR2 controller. Late-wave Griffin dates rest on the task list, with per-model detail thinnest here.
Socket and motherboard compatibility
The QL-65 fits S1g2 Puma notebooks with DDR2 SO-DIMM slots and a BIOS that lists late-2008 Griffin Athlon parts. It does not fit S1g1 boards despite the shared 638 pins. Display comes from the notebook board graphics. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2-800 SO-DIMMs in two channels through the on-die controller, with no ECC support.
A 1800 MHz HyperTransport link ties the CPU to the mobile chipset. PCIe slots and board graphics hang off the chipset.
Cooling is the notebook vendor heat pipe assembly for the exact chassis, with PowerNow! trimming clocks and voltage on battery.
Upgrade paths
On Socket S1 the upgrade is the AMD Athlon X2 QL-67 at 2.2 GHz for the fastest Athlon X2, or the AMD Athlon X2 QL-64 at the same 2.1 GHz rating. The AMD Turion X2 RM-74 adds fuller power management at 2.2 GHz. A swap must stay within the thermal design the chassis was qualified for.
