Solve : From P4 to dual core. How??

Answer»

From P4 to dual core. How?
From a rather superficial search I did on Google, it would seem that if you have a motherboard with his 775 socket, it can be upgraded to a dual core processor rather than the P4 processor that came with the board. But before I invest in a dual core processor, I want to find out if others have done this and it works good.
Okay, let's SAY just if that works at all!
If the motherboard has that Super Duke new 775 socket, which is not a socket, doesn't mean you can realy upgrade to a better Intel processor using the same motherboard? Or is the new 775 socket just a marketing ploy to get you to buy something that's not really upgradable?

Any comments please.
the motherboard has to support dual core or quad-core processors if your going to use one. Sometimes these are offered through BIOS updates.Quote from: BC_Programmer on December 17, 2009, 04:46:35 PM

the motherboard has to support dual core or quad-core processors if your going to use one. Sometimes these are offered through BIOS updates.

This basically sums it up. The socket 775 was like the OLDER 478, it supported various types of processor int he 478 Pin package , eg Celeron, Northwood P4, and Prescott P4.

It is the same with the socket 775, the SKT 775 originally came out with faster p4's in mind, mostly supported the 775 P4, Celeron D, Pentium D. There are SKT 775 boards out there that do not support Core 2 Duo or Core 2 quads either.

For instance my motherboard...ASUS P5KPL-CM. Supports all of these;

Which goes all the way up from P4, to Core 2 Quad, all on the same Socket 775 Socket 775 on the motherboard does not mean any socket 775 CPU can work. This is also true with most CPU sockets except socket 423 P4 CPUs.
Download CPU-Z to find your Motherboard info, check motherboard info online, and know if Dual Core is supported.Thanks. I will do that.
