What the A4-3310MX is
AMD A4-3310MX is a dual core Llano mobile APU that AMD released in June 2011 for socketed performance laptops. It uses the Stars K10 core design on a 32 nm process, running at 2.1 GHz base with Turbo Core to 2.5 GHz. The cache is 2 MB of L2 with 1 MB per core. Power is 45 W. Graphics come from AMD Radeon HD 6480G with 240 shaders at a fixed 444 MHz.
The MX suffix marks the 45 W class with higher base clocks and DDR3-1600 support against 35 W M parts at DDR3-1333. The extra 200 MHz base over the 3300M shows in sustained threaded work, while turbo matches at 2.5 GHz. Threads equal cores at 2.
Performance laptops pair it with DDR3-1600 SODIMMs and stronger cooling than 35 W bodies. The 45 W envelope needs a heatsink rated for MX parts. The LGA, PGA and BGA: CPU package types explained guide explains why this socketed PGA part can be serviced.
Socket and motherboard compatibility
The A4-3310MX fits Socket FS1 with 722 contacts in pin grid form. Hudson A60M and A70M boards carry it where the BIOS lists the exact A4-3310MX string with 45 W tables. A 35 W only heatsink cannot hold MX loads, so the thermal design must match.
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 that the shared 240 shader block needs. DDR3-1333 also runs where fitted.
PCI Express is revision 2.0 from the APU for discrete graphics options, Wi-Fi and storage. Some MX laptops add a discrete GPU in Dual Graphics mode where validated.
Cooling is board specific for 45 W with larger pipes than 35 W bodies. A repaste during service often restores burst behavior.
Upgrade paths
On Socket FS1 the A4-3310MX can move to faster A4 MX or A6 and A8 parts where the 45 W heatsink and BIOS allow it. Memory and storage carry over. A 35 W comparison at lower base is AMD A4-3300M on the same socket.
A platform move means a new laptop on a newer BGA package. Keep the current body after wiping the drive.
