CNR=AMR?

[Tsaico]

I was just wondering if the two were the same...

cnr is typically for NIC's

amr can be audio/modem

You are better off avoiding them since it is hard to find those types of expansion cards.

AMR= Audio Modem Riser.

CNR= Communications and Network Riser.


Finding peripherals for these slots in the retail channel will be difficult indeed. These are meant for OEM's so they can "say" they have a 56K modem, onboard audio and networking etc. IMHO they're the stupidest thing to grace a motherboard yet.

And then there is ACR advanced communication riser. all are close, and newegg advertises the ece 735 chipset with a ACR but it has a AMR.
I don't know how much they are different, but I coundn't care less if my board had one or not. I wish they would just do away with them and put a built on nic on every board, that would be worth something.

I was just curious, I knwo what the two stood for, but since modems are a type of Communication device, and I found a solid source of AMR modems I wazs just curious if you could stick an AMR modem into a CNR slot... prolly not....

A CNR is an AMR, with the ability to interface with the integrated NIC built into the south bridge of the chipset.

Therefore, AMR is for sound and modems; CNR is for sound, modems and NICs.

You can plug in AMR cards into CNR slots.

Wow, cool beans. Andy is just a god....seems to know everything...

They are not always the same. Some boards take cnr, while others take amr. It makes a difference whether the slot is at the top of the board above the agp slot or on the bottom below the last pci slot.

 

[AndyHui]

Hhmm...that's true.

Some manufacturers place the notch around the wrong way and force you to buy a proprietary riser....*cough* ASUS A7A266 *cough*....

 

[hans007]

actually amr and cnr are basically the same thing. but amr was made by an industry consortium, and cnr is made by intel. acr is backwards compatible with amr. b

 

[Bleep]

Well I have one of each sitting here on the bench and they are NOT interchangable socketwise.
Bleep

 

[Tsaico]

Bah, seems to be more trouble than they are worth. ANother thing put in there for just OEm manufacters.... specially when the PCI counter parts are cheaper and easier to find...
