![]() It doesn't matter how good the RAM is on its own. So yes, in a way, you wasted money, because a) it won't be faster than a DDR4-3600 kit with nice timings, and b) your memory system has difficulty to run such a demanding XMP profile.Įverything above DDR4-4000 may require manual tuning to make it work, it's extreme territory. ![]() And in the end, the properties of the RAM modules. Your CPU's integrated memory controller (IMC), quality depends on the individual CPU (silicon lottery, not only for CPU core quality, also for Uncore/IMC quality) Your mainboard (PCB layer count, PCB trace optimization, RAM slot layout, component selection, RAM VRM etc.) However, the following factors all affect if the RAM can run at a certain speed: So about the RAM speed that's on the packaging, you can buy RAM with whatever advertised speed that you want, but that only means that the RAM itself is capable of it. XMP is never a guarantee, it's only a goal that can be reached in optimal conditions. But DDR4-4400 is a very demanding XMP profile. On top of that, the BIOS of the 600-series had lots of problems with some XMP profiles, which are slowly being solved. ![]() dual-rank / stability testing under 4).Īs i explain there, such kits become mostly useless with 11th gen and 12th gen CPUs, because of the necessary divider for the IMC, and because those high RAM speeds are quite challenging to reach. See my thread RAM explained: Why two modules are better than four / single- vs. ![]() The more important question is, why get such a kit, with a CPU where the IMC (memory controller) needs a divider (Gear2 mode) for high RAM speeds? Your XMP is potentially difficult to run, no matter if your RAM model was listed there or not. That "Unknown" has no relevance, i don't even see that screen, because i immediately set my BIOS to Advanced View (press F7). ![]()
