Memory Upgrade

Is it OK to mix 32 GB DDR5-4800 MHz RAM with 32 GB DDR5-5600 MHz RAM in my Z2 G9 Workstation?

@PapaJimbo,

Welcome to our HP community forum!

Well, once you start mixing RAM (different brands, models, speed) all bets are off how well your RAM is going to perform, as HP desktops are known to be rather finnicky when it comes to attain max RAM speed and performance.

For example, looking here amongst HP Z2 Tower G9 Workstation Users benchmarks, only a few managed to get their RAM to run at the maximum 4800 MHz, most seeing their 4800 MHz RAM down throttled to 4400 or 4000 MHz.

So, it is probably OK to mix your RAM, but don't expect the best possible RAM performance either.  As a matter of fact, don't be surprised if your desktop won't boot up.  No harm done, it will either work or it doesn't.  I would "stick" with 4800 MHz RAM, as you'll never get RAM to run above this limit anyway.

Hi,

Thank you for your answer and suggestion. I did load in the 32 GB DDR5-5600 MHz RAM into my workstation and it does boot up fine. I understand that I cannot attain the RAM speed 0f 5600 Mhz due to the processor restrictions, and that is fine. I was really just looking to use the memory modules I had access to and to increase my WS memory to 64 GB.
