Identifying ATI Products
by Direct (Visual) Inspection

Content by ATI Technologies Inc.(original archived HERE). Edited 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

Image	Chip Markings	ATI Chip
	RAGE 128 GL 215R4Gxxxxx 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. Click here for further instructions.	Rage 128
	RAGE 128 VR 215R4Bxxxxx	Rage 128
	3D RAGE PRO xxxxx 215R3xxxxx -some versions are marked "RAGE PRO TURBO" -some versions are marked "PCI" or "AGP" -some versions are marked "2X" or "1X"	Rage PRO
	3D RAGE LT PRO xxx 215LT2xxxx or 215LT3xxxx or 215LT4xxxx or 215LT5xxxx -some versions are marked "PCI" or "AGP"	Rage LT PRO
	3D RAGE IIC xxx 215R2xxxxx -some versions are marked "PCI" or "AGP"	Rage IIc
	3D RAGE II + DVD or 3D RAGE II + 215GT2Uxxx	Rage II/II+
	3D RAGE II 215GT2Cxxx	Rage II/II+
	3D RAGE or MACH64 215GT1xxxx or 215GT22200	Rage I
	ATI-264VT2 or MACH64 215VT2xxxx or 215VT3xxxx or 215VT4xxxx	mach64 VT
	ATI-264CTx or MACH64 215CTxxxxx	mach64 CT
	mach64 210888GXxx	mach64 GX
	mach32 220068800x or 21068800x	mach32
	ATI 38800-x	mach8 see note
	ATI 28800-x or PN220028800x	VGAWONDER see note
	ATI 18800	early VGAWONDER

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".

	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.
	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.
	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.

Other ATI Chips You May Encounter

Image	Chip Markings	ATI Chip
	ATI-68860 2146886000	This is an ATI "Spectra DAC" - keep looking for the graphics controller
	ATI68875	This is another DAC - keep looking for the graphics controller
	ATI-68890 2136889000	This is an ATI Video Capture Chip, found on older (Windows 3.1) capture products such as the "Video-It!" and "Video-Basic".  These boards have no DISPLAY capabilities, and software is not provided for Windows 95 or Windows 98.
