What isAMR (Audio/Modem Riser or AMR slot)

The audio/modem riser (AMR) is an expansion slot on motherboards of some personal computers such as Pentium III, Pentium IV, Duron and Athlon. The AMR was created by Intel to enable connection with chipsets and provide analog functionality for sound cards and modems on an expansion card.

What is an Audio/Modem Riser (AMR)?

The Audio/Modem Riser (AMR) is an expansion slot on some motherboard models that allows for the installation of a combination audio and modem card. It was created by Intel to provide analogue functionality, including sound cards and modems, on a motherboard.

The AMR slot is found on older personal computers, specifically Pentium III and Pentium IV models, as well as Duron and Athlon PCs. This expansion slot was popular in the late 1990s and early 2000s when internet access was still largely dial-up, and sound cards were becoming more common.

What Does an AMR Slot Do?

The primary function of an AMR slot is to allow for the integration of both an audio and modem card onto a motherboard. With the AMR slot, a user can install a combination card that would provide both sound capabilities and the ability to connect to the internet through a phone line.

In simpler terms, an AMR slot is a way to add basic sound and internet capabilities to older computers without having to purchase separate expansion cards.

FAQs About AMR Slots

Can I still use an AMR slot?

While AMR slots were popular in the late 90s and early 2000s, they are now obsolete. Most modern motherboards do not come with AMR slots, and neither do modern expansion cards. As a result, it is unlikely that you will come across an expansion card that is compatible with an AMR slot.

Do I need an AMR slot?

No, you do not need an AMR slot. Most modern computers come equipped with built-in sound and internet capabilities, and many of these capabilities can be upgraded or enhanced with separate expansion cards that do not require an AMR slot.

Can I upgrade my AMR slot?

No, an AMR slot cannot be upgraded. If your computer has an AMR slot, it is likely a sign that it is an older model, and as such, upgrading the slot would not be practical.


The Audio/Modem Riser (AMR) slot was an innovative piece of technology in the late 90s and early 2000s that allowed for the integration of basic sound and internet capabilities onto older computers. However, with the advent of modern technology, AMR slots have become obsolete, and it is unlikely that they will be used again in the future.
