@EarthDog Ah yes thanks for that you are correct. I completely forgot that Intel moved to that gear thing with RKL.
Still I find it strange that 3,733 was 2T (presumably for stability) but overclock 2 was 1T and from what I know running 4000 14-15-15 at 1T is pretty insane. If the motherboard, cpu and ram could do that surely it could also do 1T at 3733 14-14-14 on overclock 1.
When you set RAM up to DDR4-3600-3733, then it can work at Gear 1. It doesn't change the fact that many platforms/CPUs won't run RAM at Command Rate 1N/1T at more than DDR4-3600. It may work at 1N/1T but usually works at 2N/2T (we are still at Gear 1). When you set Gear 2 then you can manually set Command Rate 1N/1T but in real it works about the same as 2N/2T. Still, the software shows 1N/1T and that's why this is a bit confusing. In this way, if you set Gear 2 and 2N/2T then it will work like it was 4N/4T and we don't really want that
In short, it works like:
Gear 1 and 1N/1T = 1N/1T
Gear 2 and 1N/1T = 2N/2T
Gear 1 and 2N/2T = 2N/2T
Gear 2 and 2N/2T = 4N/4T
Software always shows 1N/1T or 2N/2T.
I don't know about the test platform used for this review but at least on my test rigs, Gear 1 didn't work at DDR4-3733+ on any tested motherboard with my i7-11700K ES. My MSI motherboard has OC profiles up to DDR4-4000 and Gear 1 but as I said, DDR4-3600 was max with Gear 1 that could work.
