Who uses a CNR-slot?!

[Guest]

Couldn't there be an extra PCI-slot instead?

you mean those slots for the EL-CHEAPO modems?
isnt it the same thing as the amr?
i may be mistaken, but i think that they put those on there so that they can keep the system cost down for system manufacturers, because they can use the el-cheapo modems and audio cards (which use the cpu to do their tasks, making them useless to a power user, or online gamer, or anyone in general).
they usually put that slot above the agp slot, and i know that they could jsut move the agp slot up, and throw that extra pci slot in there, but they figure that because of the immense costs that making a totally different board would entail, they decide to make one board that is attractive to both end users, and system builders.
and anyways, 5 or 6 pci slots is for the most part enough.
but you might be using like tons of pci cards, and need more than 5.
but then again, you might just be wondering why they even bother to put them there, and you have already read my thoughts about that. so....there you have it....that is my thoughts on why there is an amr/cnr slot on most new motherboards.

In some cases the CNR slot takes the place of a 6th PCI slot, and sometimes they manage to squeeze a CNR in there along with all 6 PCI. And they are entirely useless for any kind of power user because all they do is provide the connections so that the CPU can do all the processing for the audio, modem, etc, robbing cycles from the important things you are trying to do with your CPU.

Except all that has changed now.

On motherboards with the nforce chipset (not that we can buy them yet...) a CNR card would provide connectors so that the audio and communication options in the chipset itself can do the processing--it doesn't get passed on to the CPU. I find it almost ironic that the before useless riser cards can now be used to provide the best and lowest CPU-using sound available for the PC.

But with any other chipset the riser cards are a waste of PCB, in my opinion.

so whats the diff between CNR and AMR? never seen a board with both, and presume its not same thing as i saw two boards from one manuf'er, one with CNR, one with AMR...

not sure, but i have been seeing a trend, and am putting 2 and 2 together...
i have seen cnr on intel motherboards, and amr on amd motherboards...BUT I MAY BE WRONG>>>DONT TAKE MY WORD FOR IT!
anyone know?
