| Q: | Since Intel 845/850 chipsets only support AGP 1.5V cards, wrongfully plugging an AGP 3.3V only AGP card on Intel 845/850 mainboard will burn the MCH chip and cause damage to your mainboard. (BW7/BL7/TH7/TH7II and all other 845/850 mainboards) BW7/BL7/TH7/TH7II |
| A: | Most of the AGP cards' gold finger includes a notch to identify AGP 3.3V or AGP 1.5V as illustrated in the picture below. An AGP card without that notch means that AGP 1.5V is not compatible and cannot be inserted into AGP slot fully. Very few graphic cards, such as the Leadtek WinFast VR300, are a 3.3V only AGP card but includes a "1.5V notch" golden finger. An abnormal golden finger such as this will permit AGP card plug into 845/850 mainboard fully, burning the chipset and damaging the mainboard. Some graphic cards have jumpers to switch between AGP 1.5V or 3.3V. Please DO make sure it's jumpered at 1.5V before use on Intel 845/850-based mainboards. |
