What the Core 2 Duo E8190 is
The Intel Core 2 Duo E8190 is a 2.667 GHz business dual core from January 2008. It runs two Wolfdale cores at 2.667 GHz with no turbo, so 2 cores give 2 threads. Cache is 6 MB of shared L2 on a 45 nm process. Power is rated at 65 W on LGA 775.
The E8190 lists alongside the E8200 at the same 2.667 GHz on a 1333 MT/s bus for business channels, without the consumer virtualization feature set. Per-model publication is thinner than on the E8200, resting on the task list and the shared E8200-class bin.
Socket and motherboard compatibility
The E8190 drops into LGA 775 boards with DDR2 or DDR3 memory and a BIOS that lists early-2008 Wolfdale parts, such as G33 and P35 boards. It pairs with business 3 series chipsets. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 and DDR3 through the board chipset in two channels.
A 1333 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 E8200 at the same 2.667 GHz with the full feature set, or the Intel Core 2 Duo E8300 at 2.833 GHz. The Intel Core 2 Duo E7300 at 2.667 GHz is the cheaper 3 MB option. Beyond LGA 775 a move to a newer platform needs a new board and memory.
