I've been in the hardware game a long time, and all the evidence I'm seeing WRT this silent data corruption issue points simply to QC, not a chip design flaw. If the problem were a chip design flaw, we'd see far more widespread reporting, as millions of this chip have shipped into the marketplace. The fact that the Russian with 5 cards purchased in Dubai could routinely demonstrate this problem with 2 of 5 identical cards, and never on the other 3, points directly to a board QC isue. Again, if the problem were a design flaw in the IC itself, all 5 cards would have exhibited the problem. -- Stan
