Colorful is Preparing DDR4-4000 C14 Memory for Ryzen 5000 Series CPUs
Colorful, a Chinese manufacturer of PC components known for its graphics cards, is apparently preparing a special RAM version for AMD's Ryzen 5000 series CPUs. The new arrival is part of the iGame series that Colorful offers. Thanks to SMZDM forums, we have specifications of the upcoming iGame RAM tuned specifically for Ryzen 5000 series processors. Coming in with all white PCB without a heat spreader, the new Colorful iGame memory features Samsung's B-dies designed for maximum speed and performance. The dies are running at 4000 MT/s with some very strict timings. The memory features C14 (14-14-14-35) timings that are supposed to bring the system latency down and improve performance even further. It is estimated that such a configuration will require 1.5 Volts to power it. While the exact name, launch date, and pricing is unknown, we can only wait and see how Colorful plays it out.

next best at 4000mhz is gskill with 15-16-16 at 1,50volt or 3800mhz at 14-16-16 at 1,50v
I chose to go for G.Skill 3600 mhz CL14 at 1.45 volt. That is still the sweet spot and bumping voltage to 1.5 volt can probably give me a bit lower timings or higher clock any way.
why can't they make the chips white too, then they would have something special...instead of tweaking around with timings/voltages etc...

Although DDR4 is de facto using 1.35V by spec it should be 1.2V.
Your question is like saying Nvidia has a performance issue with the RTX2070 and Nvidia is forcing consumers to compensate for that issue by buying an expensive RTX3090.
1.5 VDIMM doesn't kill your memory controller, High VSOC on AMD and VCCSA on Intel does.
1.5V is perfectly safe for B-die and B-die only. If it wasn't, there would be no reason to pick B-die over anything else.
Heatspreaders are better omitted if they suck thermally, like a good portion of those on the market nowadays.
1.5V is only part of JEDEC parameters as a standard that all dies should be capable of reaching. It does not test whether they can survive after months of 1.5V. We know that most of them will not, save for B-die, possibly old E-die, and now maybe Rev.B and Rev.E.
5600X still delivers equal or superior performance over official 2933 Intel at its official DDR4-3200 speed, so...
C14 will be fantastic and fantastically expensive.
C18 will be almost as good and probably around half the price.
The primary goal is to increase FCLK. Reducing absolute memory latency is an additional bonus if you can afford it but those will be marginal gains compared to the FCLK boost.
