I have a pcchips p21g and i wanna get a pentium d 930 3.0 ghz dual core for it.. socket 775.. will they match and work together?

No, Here they say that it's only compatible for P4s and Celeron Ds.

It should work with any of the P4 Prescotts, though. What processor do yiu currently have?

i have a celeron d. Is there more then socket types for capability? the mobo supports 800 mhz fsb just like the prossesor.

Not sure I understand your question....
All of the newer prescotts use the LGA775 socket, but the Pentiums D's use a different style of LGA775 socket. As far as I know they are not interchangeable.

I didn't know that the sockets for PDs are actually different. wont some boards support PDs and P4s? anyway, geno2k3, some boards will support certain processor models but not others, even though they have the same socket. So yes, compatibility depends not just on socket type.
See this. http://www.pcchips.com.tw/PCCWeb/Pr...6&LanID=2&DetailID=361&DetailName=CPU Support
There are no PDs listed.

I actualy found it YES it does support dual core chips! but its the newer version of the motherboard 3.1 http://www.pcchips.com.tw/PCCWeb/Products/ProductsDetail.aspx?DetailID=364&MenuID=92&LanID=2
Hopefully i get the v3.1 so i can order my new cpu, thanks everyone for your help.

That's cool. just be sure you have the 3.1 version of this board.

yeah i emailed the guy who sold it to me and he confirmed it is 3.1 thanks alot.
