Intel Core i5-2450P socket: LGA 1155
The Intel Core i5-2450P uses the LGA 1155 socket. It is a 95 W quad core Sandy Bridge desktop part with no integrated graphics, so a discrete card is required.

What the Core i5-2450P is
Intel Core i5-2450P is a quad core Sandy Bridge desktop processor that Intel released in January 2012 for discrete graphics towers. It runs at 3.2 GHz base with Turbo Boost 2.0 to 3.5 GHz, with 6 MB Intel Smart Cache and 4 threads. Power is rated at 95 W on a 32 nm process. The P suffix marks no integrated graphics, so every display needs a card.
The cores match the graphics equipped Sandy i5 quads at similar clocks, which makes used comparisons direct. The chip takes DDR3 at 1066 or 1333 MT/s in two channels, with AVX and virtualization support for mixed loads.
Higher base than the 2380P gives stronger all core throughput for threaded office and creation work of the period. Towers pair it with P67, Z68 or H77 boards and a mainstream 2012 card. The LGA, PGA and BGA: CPU package types explained guide places this LGA desktop part against mobile forms.
Socket and motherboard compatibility
The Core i5-2450P fits LGA 1155 in FCLGA1155 form. Both 6 series and 7 series boards boot Sandy Bridge directly. P67 and Z68 boards suit discrete only builds, while H77 and B75 work where the card covers all displays.
Power at 95 W needs a standard tower design with a full size cooler. The Socket vs chipset: what decides whether a CPU works guide details the chipset split.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 32 GB. Matched pairs feed four cores at full bandwidth. ECC is not supported.
PCI Express is 16 lanes from the CPU at PCIe 2.0. The required graphics card takes the first slot, so multi card plans need lane sharing checks. A mid range 2012 card matches the quad well.
Cooling is the 95 W tower pattern with a larger heatsink. Fair case airflow holds turbo behavior under threaded loads. The 75 × 75 mm mount is shared across LGA generations.
Upgrade paths
On LGA 1155 the Core i5-2450P can move to graphics equipped Sandy or Ivy quads on the same board, removing the card requirement for office monitors. Ivy chips need a current BIOS. The card can stay for multi display work or move to another tower. A locked office reference is Intel Core i5-2380P.
A platform move to LGA 1200 or newer needs a new board and DDR4 RAM. Keep the 2450P system for lab use where its discrete slot still matters.
Frequently asked questions
What socket does the Intel Core i5-2450P use?
It uses LGA 1155. Both 6 series and 7 series boards boot it directly.
Does the Core i5-2450P have integrated graphics?
No. The P suffix means no iGPU, so a discrete card is required.
What memory does the Core i5-2450P use?
DDR3-1066 and 1333, two channels, up to 32 GB.
Is the Core i5-2450P unlocked?
No. The multiplier is locked.
