bios Problems with expo and 4 ddr modules 5 KF660C36BBEK2-64

Level 7

cpu : amd ryzen 7950x

memory: 4 modules KF660C36BBEK2-64 (compatible with mb)

geforce rtx 4080

PSU: 850W

The truth is that I am very discouraged with ASUS and the bios they provide for rog strix x670e-e gaming wifi. I have tried several modules, all of them compatible and when I connect the 4 modules to obtain the 128GB, when I activate expo and recognizing the modules correctly (6000Mhz) the system does not start and the bios crashes. When I leave only 2 modules in the proper position, the system works correctly. If the memory is completely compatible, does that mean that Asus doesn't do adequate testing to recommend the modules? Can someone help me solve this problem?


QVL is for overclocked kits. 192GB is possibly at JEDEC speeds, as has already been explained to you. You are able to run the memory at stock, so do this.

No memory or board vendor recommends combining kits, which is what you are doing. I suggest doing some research in future before committing to purchases. As already said, nobody has told you to go and purchase two separate kits and attempt to run them together.

As the thread has clearly run its course I will now lock it.
