In most cases, All-in-One PC is an integrated system, in other words, all the components often integrated onto the circuit designed specifically, but one might possibly have chances to replace the processor. In your system, the North Bridge is ATI/AMD 760G, a slimmed down version of 780G for entry level market; the south bridge might possibly be the ATI/AMD SB700/710/750, because those devices use the same device id so it is hard to differentiate by the software utilities. The AMD K10 Bridge is integrated on the AM3 processor die. If you want to change the motherboard, you better contact with the manufacturers of your PC.
thanks for your reply,
i want to change the processor and gpu-
i have found some cpus for AM3 socket-
1. AMD Phenom II X6 1055T Processor
2. Phenom II X4 980
I got to know that all in one pc are not ment to upgrade gpus
can i use a mobility GPU?
or a external GPU
can i replace the whole southbridge with a mobility gpu
i have tried to contact lenovo but its not working i can't find technical support
(is thier any AMD store in india?)
The only thing might be possibly replaced is the processor, if it is also soldered onto the circuit, you have no chance to replace it. The GPU is integrated onto the ATI/AMD 760G chipset, you have no chances to replace it. Most All-in-One PCs are equipped with processors of low TDP, obviously, Phenom II X6 and Phenom II X64 would be improper for your system. The system you mentioned above is phase-out, so you might possibly obtain no further support.
thanks for your support UNKNOWN
Up till recently The CPU used the Northbridge and Southbridge chipsets for communication with other devices.
* PCI Express (also AGP, PCI)
* Integrated video
* communication with drives (hard drive, DVD, etc.)
* communication with USB devices
* other I/O devices
Note the Nortbridge has a direct connection to the CPU while the Southbridge has to use the Nortbridge to communicate with the CPU.
The trend has been to gradually integrate the function supplied by the Northbridge and Southbridge directly into the CPU die itself. This is evident with the recent AMD Ryzen CPUs.
In the past AMD CPUs and APUs have used different sockets.
CPUs: AM2, AM2+, AM3, AM3+
APUs: FM1, FM2, FM2+
This year this is changing with AMDs AM4 socket which is to be used with all future AMD CPUs and APUs.
