What the Athlon II X2 240 is
The AMD Athlon II X2 240 is a dual core Regor desktop processor from July 2009. It runs two K10 cores at 2.8 GHz with no turbo, so 2 cores give 2 threads. Each core carries 1 MB of full speed L2 cache for 2 MB in total, and there is no L3 cache. Power is rated at 65 W on a 45 nm process with a 117 mm² die.
The 240 was a popular budget dual for office towers with DDR2 and DDR3 board options. Against the 215 at 2.7 GHz it adds clocks and doubles per core cache at the same 65 W. Against the 245 at 2.9 GHz it trails by 100 MHz.
There is no graphics on the die. Board video comes from 7 and 8 series chipsets where fitted.
Socket and motherboard compatibility
The Athlon II X2 240 fits Socket AM3 with 938 pins. All 7 series and 8 series boards boot Regor directly.
AM3 chips also fit AM3+ boards. It also boots on AM2+ DDR2 boards after a BIOS update. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 and DDR3 in two channels up to 32 GB on some boards.
HyperTransport links the CPU to the chipset. PCIe Gen 2 slots hang off the chipset.
Cooling is the stock 65 W heatsink on the 48 × 96 mm mount.
Upgrade paths
On Socket AM3 the upgrade is the 245 or 250 on the same board. Beyond AM3 a move to AM3+ needs a new board.
