overclocking RAM with different frequencies and ddr4 timings
two RAM dies: Crucial [CT8G4DFS8213] 8 GB DDR4, 8 GBx1, 2133 MHz, PC17000, 15-15-15-36. And Crucial [CT8G4DFS824A] 8 GB DDR4, 8 GBx1 pcs, 2400 MHz, PC19200, 17-17 -17-40. The motherboard gigabyte b250m ds3h. The processor only supports 2400 MHz maximum. You need to increase the frequencies on the first RAM to 2400 so that they equal and specify the timings so that the RAMs work at maximum performance, since they are different. When using the advanced manual, on almost the same , but Boot failure detected comes out with different timings. Therefore, I am interested inNo need to drive one die at a time. Through the BIOS, set the frequency by a multiplier per Hz. And both will catch up. ... And not necessarily until 2400. It is possible and higher, the main thing is that the mother gives.
I think so first you need to bring the best memory to the characteristics of the worst and then try to drive it.
I do not know how it is with ddr 4, but I remember that memory plus or minus is not very good at chasing outside its declared characteristics .. from which I once had to change memory in general.

I don’t know how motherboards now work with different memory (I myself only had this on the first computer, others assembled it), but before the RAM worked at the frequencies of the least productive of the installed modules. Does the current iron allow you to "drive" the bars independently of each other?

I don’t know, I haven’t tried it. I tried asus x99-e. There was some kind of hell in the BIOS, I did not understand anything, but above the stated frequency, the memory probably did not work, and all this still worked in the OS fashion. in the other x99 there is a normal BIOS and there only the mode of selecting the memory frequency and timings is possible.
and logically, if there are 2x channel and different memories of the same volume or one within the two-channel - at what memory frequency would it be worth working at? most likely if the whole thing is asynchronous, the first step can work at one frequency and the second memory at another, but this is rather strange.
I also heard such stories, they say there are motherboards, where you can put, say, 4 + 4 and on top another 8 GB and it will be like the first 8 GB work as a 2-channel and the next 8 as a single-channel. wonders...
