What i'm running

That would be a question to put to the supplier of the upgraded parts, try www.newegg.com

Every motherboard that has an AM2 socket will work - preferably one with an AMD 7xx chipset. One like

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.

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.

Here is a link for reviews and online purchase: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103934

The M3N78-em mobo doesn't support AM3 processors. It is an AM2 / AM2+ platform. A wonderful GPU for you would be this. http://www.newegg.com/Product/Product.aspx?Item=N82E16814102858

If you have any other questions please write back in this thread. I will be happy to help you through your computer upgrade.

hi there..

i also have the same mobo like yours. i also thinking to upgrade my old processor with better one..

made some quick research.. i would say the mobo unable to support the new processor. checked the BIOS update n CPU support list in Abit's site..

didn't show X4 processor is supported :(

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.

well i think u'll be needing a phenom processors.. me i have a am2 socketed motherboard and im currently running a phenomx3 processor. actualy i should be having an x4, its just i run out of stocks when i bought a processor hehe so, no choice i need a processor, so i bought an x3.. i hope this would helped. phenom x4 processors will work on sockets where phenomx3 also operates.

more cpu and a better graphics card, id say get a amd athlon x2 dual core [Cpu]
And a Nvidia Gefore 8800GT

Hi Jay,
Is you're memory installed in the two yellow slots?
Try using only 1 DIMM in DDRII_1 slot.
Page 17 in you're manual. When using only one PCI-E graphics cards you do not need to plug in extra power to the board, as shown on page 19. (Only need this additional 4-pin Molex when running two PCI-E cards).
Check internal connector is plugged in item,
1 ATX_12V_2X (Pg. 23 in you're manual).
(System will not boot without this).
Also item, 2 main power 24-pin Molex cable is securely connected. Chassis Intrusion Header (By default is opened/no jumper). I don't like the CPU getting hot. It shouldn't. Do you have a spare heat sink & fan for you're CPU? Are you 100% the cooling system is running correctly?
Lastly, here is Gigabyte's Qualified Vendors List (QVL), for you're board. Corsair 2GB is not listed.
