New build with asus M4A79XTD EVO and AMD Phenom II X4 965 Black Edition Deneb 3.4GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor. When you hit the power button, the fans start but immediately stop. Motherboard green light is on. Tried remounting the CPU to cooling fan system as suggested by ASUS with no change. Any suggestions would be appreciated.

Error correction control or something. For memory sticks.

It sounds like you need to upgrade or replace your power supply. How old is the power supply and what is the make and model number of it?

AMD Phenom II X4 model 920, uses .0875 to 1.425 Volts, (DC),

http://en.wikipedia.org/wiki/List_of_AMD_Phenom_microprocessors#.22Deneb.22_.28C2.2FC3.2C_45_nm.2C_Quad-core.29

That is the average voltage range for the AMD Phenom II X 4 processor.

Look back at the AMD Phenom chart again on Wikipedia, and look especially at the voltage range for the 900e to the 945.
Now look at the ECS CPU Support page again, and you'll see your motherboard supports Phenom II X4 processors from 900e to 945.

Since the 910e and the 925 are supported, I know the technology of the 920 is supported.
The Core architecture and nanometer technology it is based on, is supported.
No BIOS update may be needed.


Yes is the answer.

For additional questions please post in a Comment.

[NOTE*
That processor can use up to 125 watts of power. You need a decent Power Supply.
That processor also gets H-O-T!
Make sure it has a GOOD cooling system, and the computer case inside, and the Power Supply, inside, are kept clean ]

you cannot use m4a78t-e to amd phenom x4 9650 because it does not support am2+ socket, it only support am3,phenom II,sempron 100, and athlon II processor.

Yes your motherboard supports AMD Phenom X4 9650 Quad. However you need to make sure your BIOS verson is greater than 1503. if not you need to upgrade your BIOS.

Caution: Update your BIOS if its absolutely necessary and at your own risk. Wrong move may spoil your motherboard.

The best quad core for that computer would be the AMD Phenom II X4 980 Black Edition. It will fit in your computer's AM3 socket, and is outrageously fast. It will cost a pretty penny though, almost $200.

Yes, you need a new one, the present unit is either filled with dust or the fan has failed.

There is ONE processor in any computer but each processor may contain multiple cores. Also each processor has what is called "cache" usually named L1, L2, and L3 with different speeds that corresponds to your processors speed. ( i vote go with AMD processors if you need one they are great with price and quality i have a phenom 955 x2 quad core and i LOVE IT 3.2ghz of speed)

No. the Motherboard only Supports Phenom II X3, Phenom II X4.

Your board supports socket AM2 CPUs the fastest of which is the AMD Athlon 64 X2 6000+ dual-core processor at 3.1 GHz.

Your motherboard does not accept socket AM3 CPUs.
