hallo my good friends.... i've checked my P4 processor using cpu-z and found out that i'm using socket LGA 775 chipsets... so, is it possible ? coz, as unknown_13 said, "He will go for the 45nm C2Dos, so it depends on the LGA775 chipset he is owning. If it's 9xx, no way he is getting a new CPU." actually, what does he meant by 45nm C2Dos ?? can that thing be seen in cpu-z too ???
You need to know what chipset
you have (915, 945, 975x, P965, P35/45 etc). LGA775 is the socket in which you put the CPU. Download Speccy from the Piriform website.
45nm is the manufacturing process. 65nm C2Dos are old and they are gone from the market, unless you buy a used one. 45nm C2Dos use less power and exhaust smaller amount of heat than 65nm C2Dos.
