Motherboard and chipset compatibility
AMD FX-8320E needs a motherboard with a AM3+ socket. The table shows which chipset series accept it.
| Series | Chipsets | Support |
|---|---|---|
| 9 series | 990FX, 990X, 970 | Needs a BIOS update Most boards accept it with a BIOS update. Check the board maker's CPU support list, and note that a board's power delivery has to handle the 125 W FX models. |
Board makers publish a CPU support list for every model. Check it for your exact board before buying. Chipset details for AM3+.

What the FX-8320E is
The FX-8320E is an efficiency tuned 8 core Vishera part on AM3+ for quiet thread rigs. It runs 8 cores and 8 threads at 3.2 GHz base with turbo to 4.0 GHz. Eight megabytes of L2 plus 8 MB of L3 cover parallel work. Power is 95 W on 32 nm from September 2014. The E suffix marks lower voltage tuning.
Lower base clocks than the 8320 trim heat while turbo preserves bursts. Eight threads handle encodes with background tasks. The 95 W envelope suits modest towers with quiet fans. The unlocked multiplier allows tuning where boards permit.
No integrated graphics exist. DDR3-1866 over two channels feeds the modules. Buyers pick the 8320E where 8 threads must run cool on AM3+ boards.
Socket and motherboard compatibility
The 8320E fits AM3+ on 970 and 990FX boards. The 95 W rating suits nearly all AM3+ VRMs. DDR3-1866 DIMMs cover stock clocks. Check the board list for the E stepping.
HyperTransport links CPU to chipset. The Socket vs chipset: what decides whether a CPU works guide covers AMD pairing. Plain AM3 boards never boot Vishera.
Memory, PCIe and cooling
DDR3 up to 1866 MT/s over two channels suits efficiency thread rigs. Matched pairs feed eight cores. ECC suits workstation boards that wire it.
No PCIe from the CPU. Chipset slots carry graphics. A mid range Radeon of the era fits 1080p gaming beside thread work.
Cooling uses AM3+ towers for 95 W. Efficiency tuning keeps fans slow. Budget boards need VRM airflow under all core loads.
Upgrade paths
On the same socket, the AMD FX-8310 at 3.4 GHz base nearby adds clocks, while the AMD FX-8370E at 3.3 GHz to 4.3 GHz above adds turbo. All share AM3+ boards.
AM4 replaced the platform. The 8320E holds efficiency 8 core duty where watts matter.
