Not trying to derail this thread, so if this becomes a subject, we should create a new one.
Very nice if more motherboard vendors announce support. This is going to be awesome publicity for AM5 platform.
Yes that is nice, I've been planning to attempt to stabilize my 64gb at CL28 soon, and they are making my result look pathetic! Some details below...
HOW??? I'm going to have to try copying some of those settings.
Voltages. I have 64gb, I haven't yet gotten 6400 stable, I COULD try, but I also can't get a 2200mhz IF clock to work so I am working on timings, and making great progress. At the default 1.4V of my dual rank chip, I can't do much, bumping it up to 1.45 gives sooo much flexibility. My timings are now even different from last screenshot and aida64 reports a 55-57ms latency. You can't stick to anything 1.4 and below and expect an improvement, at least for dual rank.
I know 1.45 is safe and I seem to recall 1.5 is safe. The issue becomes heat. The higher you go, the hotter those things get. Heat causes errors in RAM.
RAM overclocking is also a PITA. On my board, if you mess up too bad, you have to open the case, remove hardware, and hit the reset CMOS button. I added a button to the jumpers so I only have to take the side off...
At least for me, the safe mode failures almost never work and I don't have buttons on the back of my ITX board.
BTW I have one of the worst 7950Xs out there, so I'm sure others could have better results.
On Topic: That is why you shouldn't beat up AMD over the current situation. DIMMs today are very loosely binned. Many of the slowest DIMMs can run at DDR5-8000 or more. Intel and AMD are pushing the industry is catching up to this, but it takes time. On most AM5 CPUs, DDR5-8000 is easily achievable with the right kit, but speeds alone provide almost no benefit thanks to the GMI links and stuff. If they design around this, we'll see significant uplift. They are for some designs that use LPDDR5, and other designs in the future, so I'm looking forward to seeing results. I've said in the past I think Zen 5 is bandwidth bottlenecked. Hopefully we'll see something with more, or maybe with Zen 6.
