What the Core 2 Duo E4500 is
The Intel Core 2 Duo E4500 is a 2.2 GHz mainstream dual core from July 2007. It runs two Core cores at 2.2 GHz with no turbo, so 2 cores give 2 threads. Cache is 2 MB of shared L2 on a 65 nm process. Power is rated at 65 W on LGA 775.
The E4500 sits above the E4400 in the Allendale Core 2 line in stepping M0 with an 11x multiplier on an 800 MT/s bus. It exists because Intel wanted a full-cache dual core between the E4400 and the faster E4600 for mainstream buyers.
Socket and motherboard compatibility
The E4500 drops into LGA 775 boards with DDR2 memory and a BIOS that lists mid-2007 Core 2 Duos, such as 945 and P35 boards. It pairs with mainstream chipsets contemporary with Allendale. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 through the board chipset in two channels.
An 800 MT/s front side bus ties the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is any 65 W rated LGA 775 heatsink on the 72.5 × 72.5 mm mount, with Enhanced SpeedStep trimming draw at idle.
Upgrade paths
On LGA 775 the upgrade is the Intel Core 2 Duo E4600 at 2.4 GHz within the 2 MB line. The Intel Core 2 Duo E4400 at 2.0 GHz is the cheaper 2 MB option. Beyond LGA 775 a move to a newer platform needs a new board and memory.
