Described embodiments relate to a method of testing fully buffered memory modules that involves placing a buffer device, a test vectors generator, and a switch into a memory device tester, coupling the buffer device and the test vectors generator to the switch inside the tester, coupling the switch to an identical buffer device that is located on a memory module with plurality of DRAM devices, and testing the plurality of DRAM devices and the buffer device of the memory module. An apparatus implementing the method comprises a memory device tester, a memory bus, and a plurality of memory modules under test, the tester and the plurality of memory modules connected to the memory bus in a point-to-point manner, the tester comprising a buffer device, a test vectors generator, and a switch, the tester connected to the memory bus through the switch, each memory module under test having a plurality of DRAM devices and an identical buffer device.
