can some one tell me what a cnr is and what it does

CNR is another one of those proprietary slots.... like AMR and stuff. They're mostly aimed at OEM's and system integrators, to incorporate things like audio cards, ethernet cards and modems. It basically makes it real hard to upgrade if you have a CNR or AMR device in a pre-built computer you bought. Say you buy a new, faster mobo and processor - if your new mobo doesn't have the right kind of proprietary slot, you're SOL for using your old devices. just stick to PCI devices, the PCI bus isn't going anywhere anytime soon. Hell, the ISA bus is just now disappearing from mobo's and it's been around since the 286 and 386.

I believe these CNR slots are being added specifically for networking purposes. I have done a little research on them and that was the only specification I was able to find. There are CNR specific networking cards available now but they seem to be a bit pricey. I cannot tell you what the benefits of these would be nor the speed in relation to the current PCI cards on the market.

Communication and Network Riser (CNR) - The CNR slot allows the integrated network core to be used on a motherboard. CNR cards are available for LAN connections and the CNR slot can also take modified sound or modem AMR cards. But the CNR and AMR slots are not pin compatible.

Audio Modem Riser (AMR) - The AMR slot allows a sound or modem card which uses the chipset’s integrated Audio/Telephony codecs to be utilized. These AMR devices are software-driven modems and sound cards that will reduce system performance by stealing CPU cycles.

im just learning and will prouble dump this board in about six mounts msi pro 2 cpu 600 just getting parts to gether some day learing all i can from you guys cant say thanks enough overclockers auss to
