I checked my device manager, and i saw 2 chipset names:
1. Mobile Intel(R) 45 Express Chipset Series PCI Express Root Port - 2A41
2. Mobile Intel(R) 45 Express Chipset Series Processor to DRAM Controller - 2A40
Not sure which on i'm using, however I wish to upgrade my processor, I currently have:
Mobile Intel Core 2 Duo P8400 @ 2.26Ghz. 64bit Win7.
This does not only depend on your chipset model, the motherboard BIOS has to have the correct set of instructions for every processor in order to be able to utilize it, there are also some other limitations like the voltage regulator and the Heat Sink.
Unfortunately only your system manufacturer ( brand name on your computer) will be able to provide you with a list of compatible processors.
