HI ! I bought a new AMD phenom quad-core 9750 2.40ghz processor and Gigabyte motherboard. I m unable to install Windows and the system automatically shuts down every 20 min and sometimes runs for more than an hour. I have single fan and 450 W SMPS. May i know the reason ? Shud i change the power supply or Include Fans ? Pls suggest.

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

update your bios version , to a higher version , use dual core to update

i got an AMD phenom x4 9550 prossesor and i cant find anything.. not even on the AMD site.. could you guys help me?

check make sure you install all the components correctly especially the processor.
Please let me know if you need further help. you can keep in touch my me just click here.

According to the manufacturer's web-site:

the motherboard supports it, and supports quad-core CPUs.

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 :(

when it comes to new processors i would definatly suggest any intel from the core 2 series. AMD is having problems with overheating and has all but abandoned thier quest for quad core glory.

There seems to be some sort of incompatibility issue between your motherboard and the Phenom, or maybe some option is not enabled in the motherboard bios that windows is only sensing half of the GHz, like if the processor is only running 2 cores instead of 4.

About the memory diference, that same problem is because the 64bit difference. Unless you have a 64bit XP you won't see the full 4GB. Windows XP is limited to 3 or 3.5GB of ram it can use, you are showing 2.75 maybe because some video board is integrated in your motherboard and it may be borrowing an extra 0.25GB from the 3GB that are usable under windows XP 32bit OS.

Please comment what motherboard you have, since the cpu alone can't be blamed nor configured.

The Motherboard should automatically detect the type of CPU. Mine did. I started off with a dual core and went to a quad and did nothing. After replacing with the new quad core the CPU was automaticaaly recognized at start up and it required me to do nothing.
