Motherboard and chipset compatibility
Intel Core 2 Duo P8700 needs a motherboard with a Socket P socket. The table shows which chipset series accept it.
| Series | Chipsets | Support |
|---|---|---|
| Montevina (4 series mobile) | GM45, PM45 | Works out of the box |
| Santa Rosa (965) | GM965, PM965 | Needs a BIOS update 45 nm Penryn parts boot on Santa Rosa boards that list them, after a BIOS update. |
Board makers publish a CPU support list for every model. Check it for your exact board before buying. Chipset details for Socket P.

What the Core 2 Duo P8700 is
The Intel Core 2 Duo P8700 is a 2.533 GHz medium-voltage mobile dual core from December 2008. It runs two Penryn cores at 2.533 GHz with no turbo, so 2 cores give 2 threads. Cache is 3 MB of shared L2 on a 45 nm process. Power is rated at 25 W on Socket P.
The P8700 sits in the middle of the 25 W Penryn mobile line on a 1066 MT/s bus, with VT virtualization and SSE4.1. Parts carry SLGFG with SLGFE following, which board BIOS lists track. Launch timing rests on the task list at December 2008.
Socket and motherboard compatibility
The P8700 fits Socket P Montevina notebooks with DDR2 or DDR3 memory and a BIOS that lists late-2008 25 W Penryn parts. It does not fit Santa Rosa boards without Penryn BIOS support. Display comes from the notebook board graphics. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 or DDR3 through the board chipset in two channels.
A 1066 MT/s front side bus ties the CPU to the mobile chipset. PCIe slots and board graphics hang off the chipset.
Cooling is the notebook vendor heat pipe assembly for the exact chassis, with Enhanced SpeedStep trimming clocks and voltage on battery.
Upgrade paths
On Socket P the upgrade is the Intel Core 2 Duo P8800 at 2.667 GHz or the Intel Core 2 Duo P9500 at 2.533 GHz with 6 MB of cache in the same 25 W envelope. The Intel Core 2 Duo P8600 at 2.4 GHz is the cheaper 25 W part. A swap must stay within the thermal design the chassis was qualified for.
