What the Core 2 Duo E4600 is

The Intel Core 2 Duo E4600 is a 2.4 GHz mainstream dual core from October 2007. It runs two Core cores at 2.4 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 E4600 tops the Allendale Core 2 line in stepping M0 with a 12x multiplier on an 800 MT/s bus. It exists because Intel stretched the 2 MB dual core to 2.4 GHz for buyers who wanted near-Conroe speed without paying for 4 MB parts.

Socket and motherboard compatibility

The E4600 drops into LGA 775 boards with DDR2 memory and a BIOS that lists late-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 E4600 is the 2 MB ceiling, so the upgrade is a 4 MB Conroe such as the Intel Core 2 Duo E6550 at 2.333 GHz, or the Intel Core 2 Duo E4500 at 2.2 GHz for a cheaper 2 MB part. Beyond LGA 775 a move to a newer platform needs a new board and memory.
