Performance monitor VS sys.dm_os_performance_counters

Hi Experts ,

Does anyone knows why some counters values are different in performance monitor and sys.dm_os_performance_counters . and how can I make them equal.
For example buffer cache hit ratio is almost 100 in performance monitor but in DMV is different . or Checkpoint pages/sec  is  0  in performance monitor and in DMV is more than 80000.

Please give us an example (screenshot).
Also confirm that you are watching for the same instances in both counters.
