I was told by one memory vendor that the PMIC could burn out in 5 years (or simulated) if the voltage is high enough / not enough cooling. This was the early days of DDR5, so maybe that information is outdated (sorted out) or if the voltage is low enough on retail kits that it just doesn't matter. I included it for those who may want to push 1.5v+.
32GB DIMM DDR5-6000 kinda has to be SK Hynix right now. Most likely M-Die. 4800-5600 can be Micron or Hynix. Easy way to find out is look at motherboard QVL lists that have the memory type. That's how I bought this Kingston DDR5-5600 64GB kit (KF556C40BBK2-64). The RGB version is Micron. I was was going to get the 5200 M-Die and OC, but It was more expensive. Go figure.
No vendor is officially selling 4x DDR5. You'll see listings on Amazon and Newegg, but that is a 3rd party selling 2 Kits package together. If I were to add it to the charts, the timings and frequency would be at my discretion. Can't please everyone. Might just do 5600 CL40 to keep it simple and "likely compatible". 6400 CL30 would be the extreme other side of far beyond the XMP. I have 128GB now as well. Thinking of DDR5-4400.
