Oh dear, seems I have to use explicit language here
Please check the new modules ALONE, i.e. remove the existing DIMMs, insert the new ones, and check to verify whether they work properly in the system, or not.

Fine, but did you understand the text including the implications, and followed the given suggestions when adding the new modules?
I can't determine the exact type of the existing modules from the informational excerpt you provided, so I assume an incompatibility between these and the newly added modules.
To sum it all up: You'd better switch to using FTS memory modules in an FTS server, rather than HP modules. Just my opinion...
