My GTX2s do it as well with ~1.8V, but I should check each stick individually (have 3 GTX2). None of my other Hypers come close to that or run the tight subtimings these sticks can.
Purely for memory OC, would you currently buy a XII Apex or Z490 Dark KP? Both seem to have good availability and similar prices. No LN2 use planned, chilled water only with memory on ambient cooling.
hyper really struggles over 2400. Good sticks can run 7-8-6-22 around those clocks, but PSC and BBSE should still beat them on the newer platforms. Highest I've managed was 2460 7-8-6 Superpi 1M with single sided binned (2200 6-7-5 pifast at 2.04V) 2000c8 Hypers. Those settings were done on a binned x58 IMC capable of 3500+ with other memory kits, so for sure memory limited. Looser timings didn't help.
2400 cl11 is what a lot of people probably have in a ddr3 based gaming pc, and i'm guessing were sold in tens of thousands, the ram in this video is far rarer and special
These old platforms can't run more than maaaybe 2200, so the chips optimized for higher frequency at the cost of latency don't give great results in most cases. That's why Hypers were king, they had low latency at the highest frequency that the platforms of the day could run at
Can DomPlats SE/RGB 16gb dual rank B-die, clock high as new G.skill layout? You should investigate that Try some DomPlat RGB 3466 2x16GB 4.31, they overclocking pretty same as 3200c14.
my former 1866c7 kit did 2200 7-7-6 and ~1030 6-7-5 around 2.05V. I recently replaced it with a 2000c7 kit thats able to run 2166 6-7-5-20 32M around 2.07V, not quite as strong as GTX2s but still enough for my benching.
