And it's still dicey to get even pairs of matched sets to play nice together. When I built my current AM5 build, I went with 32GB of RAM -- two matched 16GB sticks. But very quickly discovered I needed 64GB minimum (I'm pretty much sitting with 20-30GB of RAM in use all the time, etc.)

So I bought another identical set (my board is dual-channel, but has 4x sockets...two dual-channel setups) and couldn't get the same 6000 level overclock with 4x as I could with the previous 2x. Using the autotune feature, my current system is currently staying happy at around 5800 in regard to memory bandwidth.

That's normal.

The motherboard supports dual-channel RAM (A and B), with two DIMMs per channel (A1+A2, B1+B2). To get the best performance, you need to run with just 1 DIMM per channel (A1 + B1). To get the most memory in the system, you need to run with 2 DIMMs per channel (A1 + A2 + B1 + B2); however, that requires lowering the speed of the RAM.

You can either have a fast 2-lane divided highway (fast transfers) or a slower 4-lane city street (bulk transfers). You can't have both.
