PURPOSE: A device for testing a graphic memory using a graphic board is provided to test a graphic memory simply and at low cost using a graphic board mounted on a main board of a computer as a test board. CONSTITUTION: A slot(110) is removed on condition that a computer main board(100) is overturned, and the slot(110) is mounted at the rear surface of the main board(100). An interface board(120) is mounted in the slot(110), and a wire is mounted in the interface board(120) for transmitting a test signal being applied from the slot(110) toward the upper side. A slot(130) which is similar to the slot(110) is mounted at the upper side surface of the interface board(120) for inserting a graphic board. If a graphic memory(140) has been mounted, the graphic memory(140) is removed and a test socket(160) is mounted in the position. Thus, a signal which was applied to the graphic memory(140) may be applied to the test socket(160). A test-objected graphic memory(170) is mounted in the test socket(160). A graphic memory test signal from the main board(100) may be applied to the slot(110), the interface board(120), slot(130), the graphic memory(140), the test socket(160), and the graphic memory(170), successively.
