Can you use 2 different SKU DRAM kits?

I have ordered a ROG Strix B550-E mortherboard with a AMD Ryzen 9 5900X CPU and Corsair Vengeance RGB PRO Black 32GB 3200 MHz DDR4 Dual Channel Memory Kit SKU CMW32GX4M2C3200C16

 

I was wondering if I could put the following in alongside the above SKU CMW32GX4M2E3200C16?

 

Other than the SKU difference of 2C to 2E the only difference I could find was Tested Latency

 

2C Tested Latency = 16-18-18-36

2E Tested Latency = 16-20-20-38

You can, however both will run at the speed of the lowest one.

That's fine as they're both 3200MHz

They might run at the same speed, but there is other factors too like timings and such, which isnt the same on the 2

there's a whole bunch of secondary timings that can turn that into a living hell :)

It may work but it's not at all guaranteed.

In general it's better to use sticks sold as a matched 64gb kit.

Anything else is luck, workarounds and the grace of god.

Thank you all for your input and advice, I will take it onboard and not mix the pairs.
