Hello Narasimha, You can find the DIMM module datasheet, in that he will clearly mention how the clk is being routed to the Chips (topology). It won't be separate clock for all the chips as it is not required. Clocks will be shared across 2 chips or mostly 4. And you have mentioned that there are 5 chips, please cross check this once. It will be even multiples always.
