That is not a safe assumption given how picky socket G34 is with memory channel configuration. > I will return the motherboard and see if i > can get one that works. Before you return the board, would you mind posting the manufacturer, part number, and specs of each of the 16 DIMMs you have installed? They should all match. Are they all indeed the same part# from the same vendor? Are they unbuffered or registered? Are they single, dual, or quad rank modules? All of these things matter, greatly. Unfortunately, Asus doesn't provide the proper table in the manual for this board that shows which combinations of speed, density, rank, and un/buffered DIMMs work in socket G34. SuperMicro does, and frankly they're the only vendor of AMD server boards I'd ever use because of their attention to all the details. Socket G34 is fairly picky regarding DIMM configurations, especially with high density (8/16GB) modules, though not as picky with low density (1/2/4GB) modules. 16 identical unbuffered, or registered, 4GB DDR3-1333 SR or DR DIMMs *should* work, so long as you don't put both unbuffered and buffered DIMMs in the same two slot channel. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
