HP Z4 G4 Workstation
Microsoft Windows 10 (64-bit)

Currently have  2 - HP 16GB DDR4 2933 MHz Registered ECC Memory modules and looking to add 2 - HP 32GB DDR4 2933 MHz Registered ECC Memory modules that would bring up to 96GB.  Can the mixing of sizes be done without affecting system performance?  Appreciate any advise.

Hello
Everything depends
The modules are compatible with each other, no problem, the modules will work at the same and correct frequency
The modules are not compatible with each other, either it does not work at all, or the frequency can be reduced
The loss could be very small

Be aware that if you are offered to do so, it will be at your own risk, the computer may become unusable, think about it

Hello,

If the modules are same model, you won´t have any problem. Sizes are not usually the problem, but so are the speeds
