I am in the process of trying to optimize power draw as much as possible in my super airflow constraint build and just scored a Ryzen 7 8700F on eBay for dirt cheap. Now I am wondering what RAM to pair it with. My main concern is idle power draw.
DDR5-5600 seems to be the fastest I can find that runs at 1.1V. There are some Corsair kits at DDR5-6000 but they are 20EUR more which doesn't seem worth it.
Then again the 8700F probably benefits a lot from faster RAM, considering it's small L3 cache... so I am wondering how much power RAM actually consumes? Would a DDR5-6400 kit running at 1.25V consume significantly more power than an 5600 speed kit at 1.1V? Does RAM have power states in the sense that it uses less power when idling and more when being accessed, or is the power draw constant because the data in memory needs to be kept alive anyway?
I found it surprisingly hard to find answers to these questions when googling, so any help is welcome
