AMD A6-5350M socket: Socket FS1r2

What the A6-5350M is

AMD A6-5350M is a dual core Richland mobile APU in the socketed Socket FS1r2 package, released in June 2013. It runs at 2.9 GHz base with turbo to 3.5 GHz, with 1 MB L2 (no L3). The thermal rating is 35 W on a 32 nm process. Graphics come from AMD Radeon HD 8450G (533 to 720 MHz). The pin grid array form allows a qualified replacement where the laptop design permits access and the BIOS lists the model.

The cores use the Piledriver module layout with 1 mb l2 in total, and threads equal cores at 2. The on die graphics block is AMD Radeon HD 8450G (533 to 720 MHz), which shares system memory over ddr3 up to 1600 mt/s, two channels. Two matched SODIMM modules help the graphics block more than raw capacity alone. The APU also carries pcie 2.0 from the apu, while SATA, USB and wireless run through the board wiring.

At 35 W the A6-5350M fits larger mainstream laptops with dual heat pipes. The 2.9 GHz base keeps everyday work responsive on battery, while turbo to 3.5 GHz helps short bursts on AC power. Memory speed follows the board design, and the manual lists qualified SODIMM kits. The How to find your CPU socket type guide shows how to confirm the package before ordering parts.

Socket and motherboard compatibility

The A6-5350M fits Socket FS1r2, a 722-contact pin grid array with a zero insertion force lever. The socket also accepts Llano and Trinity mobile parts, but BIOS support still decides each model. The soldered twin family lives on Socket FP2, with the same silicon in BGA form for thin bodies. The two packages never interchange. Check the laptop service manual for access steps and the maker CPU support list for the exact model string.

Power and BIOS decide service results on mobile. The 35 W rating sizes the heat pipe and fan, and the board BIOS must list the exact A6-5350M string. A 35 W board rarely accepts a different voltage class without thermal issues. The CPU cooler compatibility by socket guide notes that laptop heatsinks are board specific with no desktop mount pattern. For soldered FP2 the cooler question is moot, since the chip cannot be removed.

Memory, PCIe and cooling

Memory on the A6-5350M is ddr3 up to 1600 mt/s, two channels over two channels in SODIMM form. Many laptops ship with two matched modules, which helps the AMD Radeon HD 8450G graphics block that shares system RAM. Some thin boards solder the memory, so capacity locks at purchase. The board manual lists the maximum per slot and the voltage.

PCI Express is pcie 2.0 from the apu with a layout that varies by board. Most laptops in this class keep the graphics path internal to AMD Radeon HD 8450G and devote lanes to SATA storage and wireless. A discrete GPU is uncommon here. Display outputs, USB and storage all follow the board wiring, so the laptop manual is the final word on ports.

Cooling uses the laptop heatsink, not a retail mount. The 35 W envelope sizes the heat pipe count and fan curve in the original chassis. Repaste and fan cleaning help sustained clocks more than any setting change. On soldered FP2 boards the heatsink cannot be swapped for a desktop pattern. On socketed FS1r2 boards the heatsink is still board specific, so model numbers must match.

Upgrade paths

A same socket move on FS1r2 is possible in theory but narrow in practice. The A6-5350M can swap for another FS1r2 part where the manual allows access and the BIOS lists the target. Moving from a dual core A4 to a quad core A8 is the clearest gain, but the heatsink and power envelope must match. In many cases a full platform move to FP8 or newer makes more sense than a used chip hunt.

A platform move means a new laptop. Current AMD mobile lives on FP8 and newer with DDR5 and modern wireless, which no FP2 or FS1r2 board can reach. Batteries, displays and keyboards also age with the board, so a whole system replacement usually beats a board swap. Recycle the old laptop through a proper e waste path once data is wiped.
