Motherboard and chipset compatibility
AMD FX-8370 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-8370 is
The FX-8370 is the 125 W Vishera flagship on AM3+ for AM3+ performance rigs. It runs 8 cores and 8 threads at 4.0 GHz base with turbo to 4.3 GHz. Eight megabytes of L2 plus 8 MB of L3 feed games and encodes. Power is 125 W on 32 nm from September 2014.
The 4.0 GHz base leads all stock Vishera parts in sustained clocks. Eight threads cover streaming with gaming on one box. The 125 W envelope needs solid 990FX boards with real VRM cooling. The unlocked multiplier invites overclocking past stock turbo.
No integrated graphics exist. DDR3-1866 over two channels feeds the modules. Buyers pick the 8370 where top stock Vishera clocks must stay on AM3+ without chasing the 220 W 9000 series.
Socket and motherboard compatibility
The 8370 fits AM3+ on 990FX boards with 125 W VRM designs. Budget 970 boards may throttle under all core loads, so check the board CPU list. DDR3-1866 DIMMs match the stock turbo. A Wraith class cooler ships in PIB packs.
990FX PCIe slots wire graphics. The Socket vs chipset: what decides whether a CPU works guide covers AMD chipset pairing. AM3 sockets never boot Vishera.
Memory, PCIe and cooling
DDR3 up to 1866 MT/s over two channels suits flagship thread rigs. Low latency pairs help gaming minimums. ECC suits workstation builds.
No PCIe from the CPU. Chipset x16 slots carry a Radeon RX 480 class card per AMD guidance. Fast storage hangs off chipset SATA.
Cooling uses 125 W AM3+ towers or liquid with VRM airflow. The PIB Wraith cooler handles stock clocks. All core encodes need cool intakes.
Upgrade paths
On the same socket, the AMD FX-8370E at 95 W below saves power with the same turbo, while the AMD FX-8350 at 4.0 GHz to 4.2 GHz nearby trades turbo for value. All share AM3+ boards.
AM4 Ryzen replaced the line. The 8370 holds flagship stock clocks on AM3+.
