Question PC turning on/off when overclocking RAM.

So recently I bought a 32GB kit of G.Skillz RAM that says it can run up to 3600Mhz; I tried overclocking this in BIOS through XMP at 3600 but when I save it just turns on and off a few times then comes on at like 2000mhz. I keep the voltage at 1.35v and run a ASRock B450m Steel Legend.

Any ideas?? :)

I’m unfamiliar with this sorry, how do I work out which one mine falls under? I’m new to pc builds.

Thanks, last question which AMD CPU would you say would best run OC 3600mhz RAM??
Zen 2 and Zen 3 can usually hit 3600MT/s consistently, but it's never guaranteed. Zen 2 and Zen 3 APUs actually have better memory controllers than the regular desktop cpus.

Motherboards with less PCB layers will usually have worse signal integrity to the RAM slots. More sticks and more ranks will also be more demanding and even the officially supported speeds decrease if you run 4 DIMMS and/or dual rank DIMMS. I ran a 3900X in an ASRock X570 Creator and could hit 3800, then in an X370 Taichi the same CPU could only run the same RAM at 3333

first gen mainboards had issues with ram compatibility, it was new platform and wrong ram topology was selected, from 400 serie chipset it was corrected (with few exceptions like x470 taichy), if you dont touch CAD, then around 3400MHz is max, if you touch CAD, then you can hit 3600MHz
