AMD FX-8370E socket: AM3+
The AMD FX-8370E uses the AM3+ socket on 970 and 990FX boards. It is an 8 core Vishera efficiency part from 3.3 GHz to 4.3 GHz at 95 W.

Motherboard and chipset compatibility
AMD FX-8370E 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-8370E is
The FX-8370E tops efficiency Vishera on AM3+ for quiet 8 core rigs. It runs 8 cores and 8 threads at 3.3 GHz base with turbo to 4.3 GHz. Eight megabytes of L2 plus 8 MB of L3 feed threaded apps. Power is 95 W on 32 nm from September 2014.
High turbo at 95 W suits mixed gaming with background encodes. Base clocks hold steady throughput while single thread bursts reach 4.3 GHz. Eight threads cover streaming beside play. The unlocked multiplier suits careful tuning on solid boards.
No integrated graphics exist. DDR3-1866 over two channels feeds the modules. Buyers pick the 8370E where top Vishera turbo must fit 95 W cooling.
Socket and motherboard compatibility
The 8370E fits AM3+ on 970 and 990FX boards. The 95 W rating suits most AM3+ power designs. DDR3-1866 DIMMs match stock turbo. Verify the late stepping on older 970 boards.
Chipset PCIe slots carry graphics. The Socket vs chipset: what decides whether a CPU works guide covers AMD boards. AM3 sockets never accept FX silicon.
Memory, PCIe and cooling
DDR3 up to 1866 MT/s over two channels suits gaming thread rigs. Fast pairs help minimum frame times. ECC fits workstation boards.
No CPU PCIe lanes exist. A Radeon RX 480 class card from AMD guidance matches eight threads at 1080p. Chipset slots wire the card.
Cooling uses 95 W AM3+ towers. Turbo bursts need airflow. The Wraith class spare coolers run quietly here.
Upgrade paths
On the same socket, the AMD FX-8320E at lower clocks below saves money, while the AMD FX-8370 at 4.0 GHz base with 125 W tuning above adds sustained speed. All share AM3+ boards.
AM4 Ryzen replaced Vishera. The 8370E remains the efficiency turbo lead on AM3+.
