Intel Celeron 2961Y socket: BGA 1168

What the Celeron 2961Y is

Intel Celeron 2961Y is a dual core Haswell mobile part that Intel released in December 2013 for thin laptops with soldered boards. It uses the Haswell core design on a 22 nm process, running at 1.1 GHz with no turbo. The cache is 2 MB Smart Cache. Power is 11.5 W (6 W SDP). Graphics come from Intel HD Graphics (200 MHz to 850 MHz).

The two cores have no Hyper-Threading, so threads equal cores at 2. The GT1 graphics block with 10 execution units covers office work and video without a separate chip. The package integrates the dual channel memory controller and PCIe lanes on die, with LPDDR3 support for thin bodies.

At 11.5 W (6 W SDP) the Celeron 2961Y belongs to the Y series fanless group. The fixed 1.1 GHz clock suits web, office and classroom work. Laptops pair it with soldered memory in the thinnest bodies. The How to find your CPU socket type guide shows how to confirm the package before ordering parts.

Socket and motherboard compatibility

The Celeron 2961Y solders to BGA 1168 with 1,168 balls in a 40 by 24 mm footprint and cannot be moved to another board. Laptop makers qualify each model with a specific board and BIOS, so even another Haswell ULT part is not a drop in upgrade. Boards follow thin notebook layouts with soldered memory in the thinnest designs.

Power and firmware decide service results. The 11.5 W (6 W SDP) envelope sizes the heat spreader and fan curve, and the board BIOS must list the exact Celeron 2961Y string. The CPU cooler compatibility by socket guide notes that soldered mobile parts have no desktop mount pattern. Socket vs chipset: what decides whether a CPU works covers Intel pairing basics.

Memory, PCIe and cooling

Memory support is ddr3l-1333 and 1600, lpddr3-1333 and 1600, two channels, up to 16 gb. Many thin boards solder the memory, so capacity locks at purchase. Two matched modules help the graphics block that shares system RAM.

PCI Express is pcie 2.0, 12 lanes. Thin boards wire lanes to Wi-Fi and SSDs rather than graphics slots. There is rarely a meaningful graphics card upgrade on these power budgets.

Cooling uses the laptop thermal solution, not a retail mount. The 11.5 W envelope suits fanless or single fan thin bodies with a spreader over the package. Repaste and fan cleaning help sustained clocks more than any setting change.

Upgrade paths

There is no CPU upgrade path on soldered BGA 1168. The Celeron 2961Y cannot be removed, so a faster Haswell ULT part means a new board or a new laptop. Within the family Intel Celeron 2955U shows another option, but boards and firmware rarely mix across makers.

A platform move means a new laptop. Current Intel mobile lives on newer BGA packages with DDR4 or LPDDR4 and current wireless, which no BGA 1168 board can reach. Recycle the old laptop through a proper e waste path once data is wiped.
