HI,

My new motherboard offer me 2 setting for the RAM: GANGED or UNGANGED

My question is which one is the best to utilise 8Gb
 
None of them unless you have a 64bit Operating System....

Is this going to be another one of your 105 thread posts because you don't
know how to use a
search engine ???

It shouldn't matter. RAM is like a huge spreadsheet. If you've got two or
more sticks working together ("ganged"), Memory can be accessed quicker for
a single application, as the data path is wider. So if you don't do a lot
of multitasking (running several primary applications at once), but you do
use a lot of RAM for something (like video encoding of HUGE video files),
then you might be better off choosing ganged mode.

For 8Gb of RAM though, most users would find best performance in UNganged
mode. At worst, the unganged mode won't significantly slow any
memory-intensive application. At best, multi-tasking performance will be
slightly increased using UNganged mode. This is because one processor core
can run one or more applications with an un-shared stick of memory (less
memory lag time).

In real-world use, it won't make much difference either way. My opinion is
UNganged, FWIW. -Dave
 
As I said before I ask question when I do not know the answer, I check in
the book that came with the motherbaord, and there is no expalination, and
the same thing with the manufacturer website

The default is likely "unganged". Unganged operates the two RAM channels
independently. The main advantage would be on a quad core, where the cores
are all executing different pieces of code. To provide the fastest response
to memory requests, the BIOS uses unganged as the default.

"Ganged" should give the highest memory bandwidth, as both channels answer
the request for data at the same time. That is the traditional operating
mode of previous generations of AMD processors. But if the default is
"unganged", that is to give the best performance with multiple cores.

All I can tell you is, if you had a single core processor, you'd definitely
set it to "ganged". For other kinds of processors, benchmark both cases as
best you can, and then make your decision.

I didn't read this, but you can find more info in an article. For many
things it doesn't matter. One game seemed to get a small boost from
"unganged".

The quantity of memory, 8GB, doesn't enter into the decision to go ganged
or unganged. The number of sticks, may affect the maximum operating speed
of a memory channel. You may be able to coax a bit more speed, from
a two stick configuration.
