Identifying ATI Products
by Direct (Visual) Inspection

Content by ATI Technologies Inc.(original archived HERE). Modified by Major Tom.


The most accurate and reliable method of determining EXACTLY which ATI hardware you've got is to LOOK AT IT.

Power off the system and open it up. Ensure that you ground yourself on the case or power supply before touching any components.

If your graphics controller is a plug-in CARD, you may need to remove it from the system to inspect it properly.

Examine the LARGER chips on your board (or motherboard).   ATI chips you are likely to encounter are listed below, in the following sections:

Graphics Controllers
BIOS Chips
Other ATI Chips

Locate your ATI chip in the tables below, using the "Image" and "Chip Markings" columns. Then read off your chip name from the column on the right.

Note: The images shown here are only EXAMPLES. The EXACT markings on your chip may differ.


Graphics Controllers

Note: ATI "Retail" board level products will have a heat sink attached to the graphics controller and you won't be able to read anything.  DO NOT TRY TO REMOVE IT.

Note: Some products have TWO graphics controllers on them - a mach8 accelerator and a VGAWONDER SVGA display controller.   These are "mach8 combo cards" such as the Graphics ULTRA or Graphics VANTAGE.


BIOS Chips

The ATI BIOS Part Number can be used to identify a product, and is also extremely useful to ATI Technical Support in troubleshooting a problem.

To use the BIOS Part Number to identify your product, record the information from the BIOS Chip, and read "Using the BIOS Part Number to determine which ATI CHIP is on Your Product".

Image Chip Markings ATI Chip
Square Version The BIOS Part Number shown in this example is 113-51803-xxx.

Note how "113" and the "version code" (xxx) are omitted.  To obtain the "version code" for the BIOS use the ATI Info utility provided with the card.  The current version of utilities for Rage 128 products are available for download from our Rage 128 driver pages.

This is a "small square" BIOS chip, found on some of our recent ATI Rage 128 graphics cards.
Square Version The BIOS Part Number shown in this example is 113-44607-100.

Note how "113" is omitted and the "version code" (100) is on a separate line.

This is a "small square" BIOS chip, found on some of our recent ATI graphics cards.
Rectangular Version The BIOS Part Number shown in this example is 113-38501-101. This is an older "large rectangular" BIOS chip, found on many earlier products.
