No. You do one or the other. Ntpd wants the clock for itself. Ntpdate doesn't care, but it's not as good as ntpd; it can't be - that would require having the clock to itself.

Think about it: 8 ms/s, 8000 dimensionless parts per million. [...] > How can I set up the ntpd sync with server ? You have to get the error under 500 ppm first. You can do that by changing what value is added to the clock every timer tick, using adjtimex -t if I am not mistaken. That's a permanent adjustment, on the basis of which NTP can then start finetuning and dynamically keeping time.
