Yes, more powerful, dual-rank kits tend to be tougher to overclock.

I've purchased a fresh set of RAM aiming for 32GB, but I'm struggling to extract more performance from it. The kit seems stubbornly stuck in factory settings, refusing to adjust even with tighter timings or higher clock speeds. While I'm okay with the original specs, the lack of overclocking capability is frustrating. My previous Corsair model managed better overclocks, but this one doesn't seem to cooperate either. What do you think? Could it be my setup or these dual-rank kits just not handling OC well?
Higher capacity is more challenging to OC, dual rank sticks are tougher to OC than single rank sticks that have double the per-chip capacity but simpler than double the number of single rank sticks with identical per-chip capacity. It might also depend on the CPU or board, because you're using a higher frequency from the start.
I moved from simple settings to more advanced overclocking, but not being able to lower the clock speed feels a bit unfair. It should be possible to run at 2666MHz, shouldn't it? Looking back, I actually had to slightly increase my CPU's base frequency when installing the new hardware, which might indicate it's struggling to operate smoothly.
