What the Athlon 64 LE-1640 is
The AMD Athlon 64 LE-1640 is a single core Orleans desktop processor from January 2008. It runs one K8 core at 2.6 GHz with no turbo, so 1 core gives 1 thread. Cache is 1 MB of L2 on a 90 nm process with the ADH1640IAA5DH part. Power is rated at 45 W on Socket AM2. The task list shows January 2009 while board and launch data center on early 2008, which is noted below.
The LE prefix marks low energy at 45 W against 62 W on standard Orleans parts. Newegg lists the Orleans 2.6 GHz AM2 box with heatsink included. Against the Lima based 2.7 GHz G2 version it trails on clocks with a larger cache.
Memory is DDR2 in two channels through the on chip controller with HyperTransport at 1000 MHz.
Socket and motherboard compatibility
The Athlon 64 LE-1640 fits Socket AM2 with 940 pins. ASUS lists it on the M2N-VM SE board, which confirms the pairing with 700 series DDR2 boards.
AM2 chips also fit AM2+ boards with DDR2 in many cases. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2-667 and DDR2-800 in two channels.
HyperTransport at 1000 MHz links the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is the stock 45 W heatsink on the 48 × 96 mm mount, included in the box.
Upgrade paths
On Socket AM2 the upgrade is a dual core Windsor or Brisbane such as the X2 5200+ on the same board. Beyond AM2 a move to AM2+ or AM3 needs a new board for Phenom class parts.
