    I have a Dell Poweredge R720 motherboard for repair and noticed one of the chip ripped out (missing) next to memory slots. Luckily I have a spare good known working board and there is a 6 pin ic labelled AQTH I assume it is SOT457 package but trying to source/identfy what the ic is, possibly power regulator for memory slots? Does anyone recognise AQTH?
    Many thanks

    No help there but it looks like K401 has been shot at also.

    Small SMD components are notoriously hard to identify. The only really reliable way is a schematic or bom of the respective board. In this case it is rather unlikely you can get hold of this kind of documentation :(
