I don't remember a node interleaving in the BIOS -- There's a ECC mode, where I only get 4/6 slots for usable memory, or an optimized mode that uses 6/6 mem sort. Each processer has it's own set of 6-slots for memory (PowerEdge 610 dual X5660's)... I wonder if the optimizing mode is node interleaving? But the only other result results in taking a 1/3rd memory penalty...Hmm... I'm wondering about this BIOS .. I had to use pcie_aspm=force to get it to get some parts to work at all. Like the on-board I/O DMA engine -- linux didn't even see the hardware without the aspm=force. Maybe a bios update is needed? will probe along those lines... I can always call Dell tech support...still under warantee...;-) Thanks for the ideas and confirmation.... > Hope that helps. > Yep!
