What model is the motherboard?? I don't know much about servers but it could be something wrong with the particular slots in question.

it's a server board，and may be，it is not the slot's problem，the ram has been detected，but could not use。and i replace other ram，it is ok。any way，thank you for reply。

Then its a problem with the RAM. Are you using the same model and brand for all the slots?? So other sticks work in these slots, do these ram sticks work in other slots when you put them together??
