OC to DDR4 Kingston Hyper Fury 2666 Mhz.  

Congratulations on winning the ATP Cup. Great player Djokovic. Great team of Serbia.

The fault is the Cl. The noises are only a little low level augment. I'm keep in the 2666 MHz.
Thank you, Count.

No it's not worth it. A 10% increase in the clock of your RAM will have no measurable effect overall. Doubt if you will even see any measurable difference in a benchmark. Certainly not in general use.
There are many elements to performance and these will mask the RAM Module speed.

What will happen is an increase in power consumption and consequently the running temperature of those RAM modules.

If these are the RAM modules I think they are, the XMP profile is the same as the JEDEC/PnP profile (2666 MHz).

That's right!

Finally, I found what I'm looking for.
Actually, RAM runs at 3000 MHz and the latency are: 16 18 18 39 61 (the same when runs at 2666 MHz).

No more noises, no more high temperatures, test AIDA64 Extreme passed without any problems. I'm happy.
At 3000 MHz, AIDA Memory test is better than 2933:

It's a little advance, but I like.

Hello, Count:
My MB (Gigabyte B450M-DS3H) looks the AGESA 1.0.0.4. But in some forums, some people talk about the new version 1.0.0.6, that not appears on the website of GB. Also, some people there says that GB has included without explain nothing, the 1.0.0.6 inside the 1.0.0.4. I want to know if these comments are true and if it's not, when comes the AGESA 1.0.0.6. GB says that this update comes with support to high speed memories and possibilities of OC more safe than today. Can you explain to me what is the actual state of the question?
Thanks in advance.

Yes. My CPUID-Z says BIOS version 1.0.0.4 (F50). I must be to understand that is the 1.0.0.4B that you explain?

Thanks, Count. But what the features come with the 1.0.0.4B in relation with the high speed memories?
