Can you plug a socket 754 cpu into a socket 940 mobo ?

We Live for the One we Die for the One

A freinds upgrading and he wants to know this.

He just wants a pc that will last a bit longer are their any 940 mobos
out ? and when you plug or if you can plug a 754 cpu into it will it
be dual channel or do only 940 cpus do dual channel any other draw
backs benifits ?

Thanks.

Where did you hear the 939 wasnt using a dual channel memory system?
Everything Ive read says it will . It just wont use ECC which is more
expensive supposedly. Havent really checked.

See heres a post from Sudhian's forum - some tech website . Hes
responding to the claim that actually dual channel mem doesnt seem to
make a lot of difference :


I disagree with this view of dual channel memory architectures for
the medium to power user.

First of all, it is true that the Athlon 64 3400+ and the Athlon 64
FX-51 differ in their memory controllers only. However, it is not
accurate to say that one uses dual channel and the other does not. The
Athlon 64 FX-51 uses a memory controller that exclusively utilizes ECC
DDR SDRAM. It is a well-known and documented fact that ECC memory has
a higher latency, thus negatively impacting system performance. When
the socket 939 version of the FX comes out soon, it will be dual
channel, but it should allow the use of low latency DDR SDRAM. When
this happens, a comparison between an Athlon 64 ????+ and an Athlon 64
FX-?? at like clock speeds would be much more relevant to this
argument.

In addition, many people (myself included) only upgrade their
computers every four years or so. When you buy an “overrated and
expensive” dual channel solution, you are buying for the future.
Again, it is a well-known and documented fact that computer software
increases in both complexity and footprint each year. While the
current gap between similar dual and single channel systems may be
relatively small in some cases, the same won’t be true three years
from now. This is especially true of the Athlon 64. With it’s yet
unused 64 bit capability, it is almost a guarantee that the software
made for these systems will become significantly more bloated, and in
many cases would benefit from more available memory bandwidth. I would
like to see a benchmark comparison of the 3400+ and the FX-51 circa
2006 with modern software.

What's In A New Socket

With the introduction of the 939 platform, we will see a convergence
of platforms on the mainstream and high end desktop market for Athlon
64. Until now, the decision between the mainstream Athlon 64 and the
FX version of the processor brought with it the problems of choosing
between registered memory for a dual channel platform originally
targeted at the workstation market and unbuffered memory for a single
channel platform. The 939 pin platform brings us the ability to use
unbuffered memory (which is slightly faster, cheaper, and more
available than registered memory) in a dual channel configuration with
either an Athlon 64 or an Athlon 64 FX processor.

Not that any platform is (or ever will be?) future proof, but 939 will
provide its adopters with a broader range of options for processors.
We have already hit the upper limits of the 940 desktop platform in
the FX-53 processor, and the 754 pin Athlon 64 will only reach one
speed grade past the current high end 3400+ to the 3700+ (at least as
far as current AMD plans indicate).

Of course, midrange and high end platform convergence doesn't mean
that the 940 pin and 754 pin platforms will go away. We will continue
to see 940 pin processors and platforms in their original market
(workstation/server) sporting AMD's Opteron processors. The 754
platform will become the new home of the Athlon XP and AMD's value
line of processors. The new Athlon XP will be a trimmed down, 32bit
only version of the Athlon 64.
