What the A6-3430MX is
AMD A6-3430MX is a quad core Llano mobile APU that AMD released in December 2011 for socketed performance laptops. It uses the Stars K10 core design on a 32 nm process, running at 1.7 GHz base with Turbo Core to 2.4 GHz. The cache is 4 MB of L2 with 1 MB per core. Power is 45 W. Graphics come from AMD Radeon HD 6520G with 320 shaders at a fixed 400 MHz.
The MX class pairs the highest A6 base clock with DDR3-1600 support at 45 W. Sustained threaded work runs faster than 35 W M parts, while turbo matches the late M refresh. Threads equal cores at 4.
Performance laptops pair it with DDR3-1600 SODIMMs and stronger cooling than 35 W bodies. The 45 W envelope needs an MX rated heatsink. The LGA, PGA and BGA: CPU package types explained guide explains why this socketed PGA part can be serviced.
Socket and motherboard compatibility
The A6-3430MX fits Socket FS1 with 722 contacts in pin grid form. Hudson A60M and A70M boards carry it where the BIOS lists the exact A6-3430MX string with 45 W tables. Late 2011 firmware matters for this December model.
Memory choice follows the MX class with DDR3-1600 SODIMMs. The Socket vs chipset: what decides whether a CPU works guide explains why the maker list decides.
Memory, PCIe and cooling
Memory support is DDR3-1600, two channels. Two matched 1600 MT/s SODIMMs give the rated bandwidth. DDR3-1333 also runs where fitted.
PCI Express is revision 2.0 from the APU for discrete graphics options, Wi-Fi and storage.
Cooling is board specific for 45 W with larger pipes than 35 W bodies.
Upgrade paths
On Socket FS1 the A6-3430MX already tops the A6 MX range, so faster moves mean A8 parts where the heatsink and BIOS allow. Memory and storage carry over. A 35 W comparison is AMD A6-3420M on the same socket.
A platform move means a new laptop on a newer BGA package.
