A780GM-A is built with AMD 780G chipset, integrated DVI or HDMI interface (passing HDMI CTS v1.3b): single-link support only for HDMI, 30-bit dual-link support for DVI. HDMI 1.3 Prior to Version 1.3, HDMI supported a clock rate of 165MHz or 4.95 Gbps, transferring 165 million 24-bit pixels per second. Introduced in 2006, HDMI 1.3 increased the rate to 340MHz (10.2 Gbps) to accommodate 2560x1440 HDTV resolution with pixels up to 48 bits, known as "deep color." HDMI also supports eight channels of 24-bit uncompressed audio at 192kHz. HDMI 1.3 uses two types of cables. HDMI Category 1 cables are rated for 720p and 1080i TVs. For higher resolutions, HDMI Category 2 cables are required. See HDTV.

NO , A780GM-A V1.0 can not support AMD Phenom x 4 9850 CPU ,

Please enter BIOS setup to change "CPU Over-clocking Function" item and set "Enabled" for Over-Clocking function.

The answer is no due to OS 32 bit limitation. You may need to use 64 bit OS instead. For more information, please refer to folllowing message from Microsoft.

Due to PC architectural requirements such as motherboard resources and OS limitations,desktop platforms using 4GB or above memory may be unable to take full advantage of all memory populated on the system. The available memory may report approximately 3.12 GB or less depends on system configurations.

To take advantage of the system memory 4GB or above installed, the computer must meet the following requirements:
‧ An x64 (64-bit) version of Windows system.
‧ The chipset must support at least 8GB of address space.
‧ The BIOS must support the memory remapping feature.
‧ The CPU must support the X64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this instruction set.

In addition, the 32-bit versions of Windows will reserve a portion of memory for critical system functions such as chipset, BIOS flash, PCI Express, etc. If you have 4GB installed, Windows will indicate less than 4GB is available.

The below table listed AMD Athlon II X3 CPUs that ECS has tested and qualified for use with this model.

Fully buffered RAM is a memory module technology, targeted at servers. The main difference between fully buffered RAM and unbuffered RAM is that on fully buffered, the communication between the memory controller and the module is serial. Whereas on unbuffered RAM this communication is parallel. This model can support unbuffered RAM but fully buffered RAM. The memory QVL listed the memory we have tested and qualified. We suggest user to use with this model.

This MB design is supporting up to 95W power plan. But if the CPU with 125W and listed in support table, it means that this CPU has been test and qualified by ECS. Because it is out of specification, so there is an asterisk (*) marked at YES* to identify. There are two AMD Phenom™ II X4 965 Black Edition CPU, one is 125W, the other is 140W, both cannot be supported by A780GM-A V1.0. Please refer to the M/B support list:
