My understanding is that DDR5 is very sensitive to matched pairs of modules. I don't think you can rely on individually purchased sticks working together. Not to say that it can't work, but it might be a crapshoot.
I wonder how long it will be until Steam Machine owners start selling their original sticks to other Steam Machine owners, and then buying a matched pair for themselves.
You can if you buy the same spec. People often don't read the notes on what they buy, I think that's the problem.
Even modules sold under the same model number may use chips from a different manufacturer, or have a different PCB layout. These differences can make some modules incompatible with otherwise seemingly identical modules.
Hmm I thought the fine print listed the chip info.
Its been a while since I build my PC.
