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.

IMO for most people a looser 1.35v 4000 will be good enough, C14 is good, but I bet we will be paying too much for the performance uplift.

C14 4000Mhz that's awesome. I just bumped my mem to 16C and 3600Mhz and it works just flawlessly. I think they can do more but still you have to get the Cas Latency up as well. C14 for 4000Mhz is great. The price for these will most definitely hit the roof.

but with only (yes only) 1,5 volt this must be a very good binning process. ok the 1,50volt is just estimated
next best at 4000mhz is gskill with 15-16-16 at 1,50volt or 3800mhz at 14-16-16 at 1,50v

1.5v 4000MHz clock speed and NO HEAT SPREADDER!!! Surely these are going to need a fan directly blowing over them to be stable inside a case!?!

That's some pretty wild timings for 4000 mhz memory at 1.5 volt. But for what I have seen, 4000 mhz gives minimal benefits over 3600/3800 mhz and mostly 1-3 % gains even with very strict sub timings. The price is probably a bit high as well. Also I hope these memory modules come with a heatsink, else it sounds like a hot disaster just waiting to happen.

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.

soooo fugggly..... white pcb with black chips, yUk, yUk, yUk.... :(

why can't they make the chips white too, then they would have something special...instead of tweaking around with timings/voltages etc...

thats a non-specific, generic photo, not the actual product. duh

How does 1.5V impact memory controllers?
Although DDR4 is de facto using 1.35V by spec it should be 1.2V.

Glad i have the patience and sit this Ryzen 5000 out until Q1 2021, there is a lot unknown yet regarding memory.

1.5V is still within the required, JDEC parameters.

Nothing; this aint no Intel that would die because of setting a too high MC voltage.

AMD's latency issues persist. Why force consumers to purchase expensive RAM to compensate?

This must be a difficult time for you, but to answer your question: there is no issue, you can just make it even better.

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.

AMD is still posting benchmarks @3200 as reference, no one is forcing anyone to go for 4000.

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...

READ the press release. Oh my god, how did you manage to start a computer up today? Or did somebody else do that for you?

1.5v without heatspreaders? Don't RAM chips get hot above 1.4v and start needing actual airflow even on the ones with heatspreaders?

Physics applies to semiconductors regardless of the manufacturer.

You're on the money there.

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.

I wouldn't exactly call it an issue - utilizing fast RAM to maximize performance is part of how the microarchitecture works. By your logic, why should Intel force consumers to buy a high-end Z490 motherboard and expensive cooling to utilize the overclocking feature that they paid for?

I wish more people could understand this. Many heatspreaders are a triple-disaster that just add cost, obstruct the CPU cooler, and cook the RAM.
