What the Turion 64 ML-40 is
The AMD Turion 64 ML-40 is a 2.2 GHz mobile single core from June 2005. It runs one K8 core at 2.2 GHz with no turbo, so 1 core gives 1 thread. Cache is 1 MB of L2 on a 90 nm process. Power is rated at 35 W on Socket 754.
The ML-40 served upper mainstream Lancaster notebooks on an 800 MT/s HyperTransport link with an 11x multiplier. It exists because buyers wanted a 2.2 GHz Turion with the full 1 MB cache below the flagship ML-42.
Socket and motherboard compatibility
The ML-40 fits Socket 754 notebooks with DDR memory and a BIOS that lists Lancaster parts. It pairs with mobile 754 chipsets contemporary with the June 2005 launch. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR in a single channel through the on-chip controller.
HyperTransport at 800 MT/s links the CPU to the chipset. PCIe or AGP slots hang off the chipset.
Cooling is the notebook vendor heat pipe assembly for a 35 W chassis, with PowerNow trimming clocks and voltage on battery.
Upgrade paths
On Socket 754 the upgrade is the Turion 64 ML-42 at 2.4 GHz at the same 35 W, or the AMD Turion 64 MT-40 at 2.2 GHz for 25 W operation. Beyond Socket 754 a move to Socket S1 needs a new board for Richmond and later mobiles.
