Socket AM3 platform for Phenom II builds

This ATX motherboard uses the AMD 870 chipset and a Socket AM3 interface to support 64-bit AMD Phenom II processors. Dual-channel DDR3 memory runs at 1600 MHz when overclocked or at 1333 and 1066 MHz by default, with a maximum capacity of 16 GB. Six SATA ports and six USB 2.0 back-panel ports handle storage and peripherals.

Builders keeping an AM3 system alive

The board suits enthusiasts maintaining an existing Phenom II rig or assembling a budget secondary machine from spare parts. Two PCI Express x16 slots are provided, though the second operates at x4 electrical speed, limiting multi-GPU scaling. A single PCI Express x1 slot and one legacy PCI slot cover older expansion cards. Realtek ALC889/892 audio delivers 8-channel output with Blu-ray sound support.

Steady throughput for long sessions

Under sustained load the PCI Express 2.0 links and Gigabit LAN controller maintain consistent bandwidth for file transfers and network streaming. The Realtek 8111DL Ethernet chip integrates MAC and PHY for stable 10, 100 and 1000 Mb/s operation. Onboard audio and USB 2.0 controllers run within spec without throttling during extended use.

商品問答

Which AM3 Phenom II CPU do I need to pair with this board?

The socket accepts any 64-bit AMD Phenom II processor, so choose the model that matches your performance target and power budget.

Will my PCI Express 2.0 graphics card run at full x16 speed in the primary slot?

Yes, the top PCI_E2 slot delivers PCIe 2.0 x16 bandwidth, while the second x16 slot operates at x4 and the single x1 slot provides one lane.

How can I verify the dual-channel DDR3 memory is running at 1600 MHz after assembly?

Enter the BIOS and confirm the memory frequency reads 1600 MHz with both DIMM slots populated; the board also supports 1333 and 1066 MHz if the modules default lower.
