TSC: CPU0:0 ACPI: 998: NO MEMORY DETECTED IN SRAT NODE1. THIS CAN CAUSE VERY BAD PERFORMANCE. As you know the blades have 2 memory banks the left bank is empty and the right one is full I have 2 processors installed. should I put some memory in the other bank? what is the best way to share this memory? regards Domenic Fri, 01 May 2009 13:56:00 GMT https://community.hpe.com/t5/bladesystem-general/hp-bl495c-memory/m-p/861#M23417 Domenic 2009-05-01T13:56:00Z https://community.hpe.com/t5/bladesystem-general/hp-bl495c-memory/m-p/862#M23418 If you have memory only on one side, the second cpu would have to use the other cpu's memory controller to access the memory.

AMD Bus architecture has a CPU to direct memory access. This has been one of the advantages of AMD over Intel, until the recent Intel 5500's release.
