Gururu I am so confused. Is it out now or not? Does it or will it impact current AM5 processors? Who had it first Intel or AMD? Does Intel Core 200 actually use it? What sort of impact did it provide? Why does AMD biding their time help anybody? I know I saw a statement or two addressing these matters, but I am still confused. Reply

Intel uses it but no current AMD cpu actively supports CUDIMM. Instead you need to run them in bypass mode, which treats them as regular DIMMs. The big benefit is that your IMC isn't required to drive the clock signal for the entire memory bus, instead only driving to the front of the DIMMs. The DIMMs have their own clock chip that will take over and drive the signal for that DIMM. In a practical sense it means much less voltage required on the CPU side. Reply
