Hi, I have a ECS 780GM-A rev 1.0 mobo and a Brisbane 5200+ CPU and I'm going to upgrade it to a Phenom 955 C3

I checked the ECS site and says that the 955 C2 will work (even when the mobo supports 95w CPU), but don't have info for the C3 revision, so I'm asking you about this

The mobo have the lastest BIOS, nothing of overclock planning


PD: English isn't my native language, so forgive any grammar mistake ;)

You speak better English than most English people. ;) 

The AMD 'Deneb' 955 (3.2GHz, C3) processor has a maximum power consumption of 125w. If the motherboard only supports upto 95w models then please disregard the 955 CPU... :)

The strange thing is that in the ECS site says it CAN, even some Phenom II x6

Copy/paste from ECS:

Question
Does A780GM-A V1.0 can support 125W CPU ?

Answer
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. In addition to the table listed CPU, other 125W CPU cannot be supported as well.


I'm confused, I don't want to buy another mobo for now and Bulldozer is too much for me

I believe the 5200+ is an AM2 whereas the 955 is an AM3. AM3 will only go "SAFELY" in an AM2+ mobo. You may have to go with the AM2+ versions of Phenom II to be on the safe side because of the difference in voltage planes.

The Phenom II X4 840 is 95W. Is this your board?

Yes, the 5200+ is AM2, but the motherboard is AM2+, and as far as I know AM2+ sockets have support for AM2, AM2+ and AM3


After the 955 there are Athlon II x4 20 USD cheapers, and for some extrange reason a Phenom 925 is 10 USD expensivier. There aren't AM2+ Phenoms here

Some AM2/2+ mobos can take CPUs up to 95W. That Phenom II 940 should work even if not listed (it's an Athlon II X4 actually). Or get an Athlon II.

I found a Phenom 955 C2 for a few bucks less but also sent a mail to ECS asking for the C3 revision

Any diference between the C2 and C3 steppings? just in overclock?
