Yes, Dual Core processor will support from 915 Mainboard
its the main processor normally at this time dual core or quad core. - It depends on the age of the product as to the mother board capabilities
no but it can support core 2 quad
No
You can technically go all the way up to the Phenom II 1090T Hexi-Core Processor with this motherboard, but the processor won't be able to be utilized on the older AM2+ socket. I'd suggest the Rana 3 core Athlons or perhaps a Phenom II X4
The Intel corporation says yes, it supports core 2 Duo processor.
Intel DG45ID - It has DVI and HDMI ports with 7.1 Audio
yes it will
Yes, however it depends on your operating system and if its a 64 or 32 bit processor
No. The Intel 865 chipset doesn't support dual-core processors.
•Multi-core processor•Dual-core processor•Quad-core processor
No it does not.
This depends entirely on the board itself. look up the board model, and find out if it can take the X2 at all. After that , you should be able to simply remove old core and insert new core. Be careful with the metal heatsink and fan if it uses clip. If you crack a stupid clip you screwed the whole motherboard. (I once did that and was greatly annoyed!)
