    Hi,
    As i aware there are two components in SQL Server with respective to SQL Memory Management.
    1) BPool
    2) MTL
    Question : In 64 Bit Machine how BPool and MTL Allocation being calculated by the server.

    Thanks.

      Yes there are two components in SQL(BPool and Non-BPool). The allocations are calculated in the same way as 32 bit system (with some minor changes) but the overall allocation algorithm remains similar.
      1) Allocated Non-BPool Memory as Reserved (256 + Thread Stack(128))
      2) Allocated BPool Memory Max BPool = Min(Min(Max Server Memory, RAM), (VAS – Non Bpool – MemoryforDLL_EXE – M_pbuf))
      3) Remove the Reserved flag from the Non Bpool memory allocated in Step 1 and mark it free.
      4) Any remaining VAS area is also marked as Free memory (used as non BPool memory).
