Product: elitebook 845 g9

 

I was wondering to upgrade my memory for elitebook 845 g9 and it looks like there are 5600mhz sodimm modules now. On the specs page I can only see 4800mhz but I'm not sure if that's the limit or just what was able to be configured with the laptop at the time, as it lists all the configurations of memory you'd get at checkout. It has a ryzen 6850u, i know some laptops have 6400mhz with soldered memory so the memory controller should be able to do it. I'm not sure if there's any other limitations like with bios if I got the 5600mhz memory modules instead?

Chapter 1, page 1 of the service manual indicates all processors run the memory at a max speed of 4800 MHz.

 

Maintenance and Service Guide (hp.com)

 

You can install a DDR5-5600 MHz memory chip but it is only going to run at 4800 MHz.

 

The processor specs on the AMD website indicate the same.
