I am creating this topic in order to clarify the compatibility between different chipsets/motherboards with different generations/revisions of LGA775 processors. This is more like a general topic and will include memory compatibility and also when necessary storage/video card compatibility.
1. For the first problem let's take the first generations of Intel chipsets for LGA775: 915p/925x/925xe - they support Prescott all revisions and do NOT support dual cores such as Pentium D, but do they support Cedar mill - the last Pentium 4 revision with the best - lowest - power consumption ? Another problem here is the memory: on Wikipedia the maximum amount is 4gb - this is the maximum addressable limit of the chipset meaning you have to use 1gb modules or 2gb will also work - you can put 4 2gb modules but the board will only recognize 4gb?
2. Second problem: Intel 945p/955x support all Pentium 4/D but some motherboards support Core 2 duo also. 945p can address 4gb of ram maximum or did someone tried more?
3. Third problem: Intel 965p/975x can take first Core 2 duo revision with 1066FSB only or they can take the last models with 1333FSB; dual cores and quad cores have different revisions - are they all supported or only certain revisions?
4. Fourth problem: Intel P35/X38 have the broadest support - practically all LGA775 CPU are supported by these boards - are there any exceptions?
5. Fifth problem: Intel P45/X48 support all Core 2 duo all revisions but probably not the early Pentium4/D - are any boards that can take all LGA775 CPU with these chipsets?
6. Sixth problem: others chipsets from Intel such as 865/875
7. Seventh problem: non Intel chipsets - NVIDIA 600/700 series
8. Eight problem: non Intel chipsets - VIA PT800/900 series
The problem is not limited to the CPU/chipset but also to the motherboard manufacturer - late BIOS versions if released means more support sometimes!
