How are the slots keyed on the MSI? On the Tyan, the 64/66 slots are
keyed for 3.3V operation, while the 32/33 slots are keyed for 5V
operation. If this is the case on the MSI as well, and you could
put the video card in either sort of slot, then it probably is supposed
to support either voltage. But perhaps it doesn't really, so that
it is flaky and causes hangs when operated at 3.3V?
