RDimm (registered/buffered) RAM and standard RAM should not be mixed. I am not sure you can even install them in the same slots. There are different notches in the bottom. If your board can use either you still need to match the type and speeds because registered RAM uses an extra clock cycle to process data so it will not sync with standard non buffered RAM.

Go to crucial.com and use their online tools to see what you have and what will work.

It would help to know the rest of the system specs. Are you asking about a desktop or laptop? Do both sticks of RAM have identical specs? Did you manually configure the memory settings in the BIOS?

It could be incompatible with motherboard.
Try switching memory sockets to see if you have a bad socket (both in both sockets one at a time).
Run Crucial test to see what is compatible.
If it should otherwise run but does not then return it for replacement. Most memory has a lifetime warranty if purchased retail (not OEM).

You have to be a little bit crazy to keep you from going insane.

i matches the specs of both sticks and they were mostly same
i guess the problem would be somewhere in the new ram
for now,, i find replacing it as the best option...
