Using the right CPU together on the right mobo

I want to know if I can mix and match AMD and Intel CPUs if they have the
same amount of pin holes on motherboards. Anotherwords, can I use a Intel CPU
on an AMD motherboard if it fits. Yes or no?
Any help would be greatly apprecaiated.
Thanks, attilathehun1

Absolutely NO!

Boy, you'd really have to have a good motherboard. But your mobo
manual should definitely clear this question up for you. I'm voting no.

A long time ago, there were cases where there were interchangeable
processors.

http://en.wikipedia.org/wiki/Amd_k6

"The main advantage of this particular microprocessor is that it
was designed to fit into existing desktop designs for Pentium branded CPUs"

http://en.wikipedia.org/wiki/Socket_7

"Socket 7... accepts Pentium microprocessors manufactured by Intel, as well
as compatibles made by Cyrix/IBM, AMD, IDT and others."

Now, the sockets are all different. If you check the
bar near the bottom of this article, it lists a large number
of different CPU sockets.

http://en.wikipedia.org/wiki/Socket_AM2

A current Intel would be LGA775 (775 contacts, based on land
grid array). The AM2 socket, popular for current AMD processor,
has 940 pins, and uses pins and not flat contacts like LGA775.
So there are significant differences between processors and how they
connect to motherboards. You cannot swap them any more.

And even when you see two sockets with the same pin count listed,
there can be differences in the keying pins. A couple of
pins are offset, preventing different families of processors
from being plugged into the "wrong" socket.

As an example, compare an AM2 (top) to an older S940 socket.
(Note - rotate one image 180 degrees, before comparing them -
I use an old evaluation copy of Photoshop for picture viewing...)

They both have 940 pins, but putting the wrong processor
in the socket, busts some of the pins off. The four keying
features are in different places.

The electrical interfaces on modern processors are entirely
different. AMD uses Hypertransport. Intel uses their
quad pumped FSB. The protocols have nothing in common.

Why ask HERE? This has NOTHING to do with the OS and pure hardware.
As such, it is out of place here - just like you, who have been told
this many times before.

Ask elsewhere

The processors ceased to be interchangeable when Intel introduced the
Pentium II using the Socket 1 interface. They stated that as it was
proprietary, and no one else could make processors that fitted it. The
intention was, of course, to freeze AMD out of the market. But it
backfired. Freed from the shackles of compatibility, AMD went on to produce
many processors that, although they required their own dedicated
motherboard, were considerably superior to the Intel offerings in many ways.

Like most wars of this type, the claim for superiority see-saws between the
designs. Intel probably holds the crown at the moment but, as ever, this
may only be a temporary arrangement. There is little doubt that AMD's
graphic processors (under the ATI brand) are superior to Intel's current
offerings.

Wrong boring and repetitive.
 
In fact, AMD presently use three sockets for different classes of processor.
So, you cannot even assume that an AMD board will accept an AMD processor!
Unless you're in the trade, it'd best to ask a supplier for advice, or choose
a bundle-deal which clearly is compatible.

Don't forget that new boards mostly will use DDR2 memory, the DDR memory
from an older board has a different pinout. You may also need a new PSU if
the existing one doesn't have a 24-pin (20+4) main connector. Oh, and the AM2
sockets use adifferent fan fixing, so...

No I didn't. The attribution marks clearly indicate that.

You should respond directly to the post that that response was made in.
Also you top posted. Your response should be underneath the post you are
replying to so that the conversation flows logically.

My advice is to NEVER "mix 'n match" CPU/Motherboard combinatioins.

If you MB is an Intel MB, use an Intel CPU.
IF your CPU is an AMD, use an AMD motherboard.

This bad idea of "mix 'n match" extends to other devices, also,
including Desktop Keyboards/mice/dongles. NEVER mix a dongle from one
OEM with a keyboard/mouse from another OEM -- especially if one is
using a Bluetooth Dongle, since Bluetooth is already rather flakey in
Windows anyway.

Well, it's been a long time since I've been able to post a message here. As
far as listening to you OldDuke, I'd like to duke it out with you. LOL
Getting back to the problem. I see here that my Intel Celeron CPU fits
socket PGA 370 P6 bus and the Pentium III CPU uses the same mobo socket PGA
370 P6 bus with 370 pins. The Intel Celeron is a stock Compaq Presario 5000 A
Series PC and the Pentium III is a Gateway Performance 800 PC. Both are older
PCs.
My DIY PC that I built 3 years ago was the first problem that started the
domino effect to start me troubleshooting all these PCs in the household. The
DIY is an AMD chip unlike the other 2 Intel chips. This DIY bought from
CompUSA as a set mobo/CPU combo was about $185.00 out the door. I had to
install the heatsink/fan onto the CPU. That was my first install of a
heatsink/fan assembly. I did feel great after getting it on. I took it into a
PC store and the PC tech told me $25 bucks to install it. I told him to give
me a break and he told me to use this screwdriver and that's all I'll tell
you for free. For 10 bucks cash he showed me how to do it.
So, now getting back to the DIY mobo/CPU deal. The motherboard is a M7VIG
400 that supports AMD processor. It's a Socket A EV6 bus with 462 pins.
Actually on the mobo it says LOTES Socket 462. I see on the CPU socket chart
that it's listed on the Socket A list.
So, I see now that the 2 older Intel chips are interchangable and the AMD
is not. Different pin counts and the Intels are much older than the AMD DIY.
Thanks, attilathehun1
PS Don't take it personal OldDuke buddy, I'm just playing around with you.
