I know your into computers and you know your stuff, I just do not think it is a rare thing that people can run 1933Mhz FCLK.I may be wrong on that because of my small sample size but I am also sure I did not have extreme luck with good CPU's that can run 1933Mhz FCLK.
Thanks for share, +rep :thumb. .

1933MHz does seem rare to me from all the threads I view. Then also from my experience with CPUs I've had.

Perhaps mobo does have an effect as well. There was a post by a member in the Crosshair VIII thread where he had a few boards (all C8x) and when he took a combo of CPU & RAM which did 1900MHz on one board and moved it to another it didn't.

I had something similar with Threadripper setup. I moved CPU & RAM from ZE to ZEA. I had to do a tweak which was not needed on ZE, to attain same RAM MHz on ZEA.

You know what it may just be motherboard that is the factor of running certain settings . Do I know for sure ,no I do not I,I can only relay my experience.F that is a lot of commas.Still I stand by Ryzen tuned timings is better than FCLK clocking for normal use.

Thanks again for share of your testing .

Techspot/HUB did some testing with a RTX 2080 Ti. You'll note in some games 3000MHz [Manual] matching/closing in on 3800MHz [CL16], 3800MHz [Manual] takes the top spot. They used 3 differing modules.

Quote:
We ran the T-Force Dark DDR4-3000 memory in its out of the box configuration with the XMP profile loaded and nothing else altered. Then we manually tuned all timings for an optimal Samsung S-die configuration at 3000 MT/s. The G.Skill FlareX memory was tested in its out of the box spec with XMP loaded and then also lowered the memory speed to 3000 MT/s, so we have a CL14 and CL16 comparison between the FlareX and T-Force memory. Finally, the TridentZ Neo also in the out of the box spec at 3600 MT/s, a 3800 MT/s overclocked configuration using the XMP timings, and then a max OC configuration at 3800 MT/s with manual timings.
From Techspot's review and say what we know of other RAM ICs. I think it's also clear that you may gain the MHz on say another RAM IC, but you may not see the full benefits until timings are tightened and then it seems Samsung B die tightens the most.

The other factor is what resolution you use IMO. Techspot's testing was all at 1080P, perhaps if it had 1440P results, we'd see that for a gamer at that resolution there may be less justification to vie for higher RAM MHz, etc, etc.

I hope by my post it is clear I detract no value from your shares and in a way echo your share. To see the gains from FCLK/UCLK/MEMCLK several factors must be considered.

@olegdjus & @gerardfraser

Great result on getting 1933FLCK to work on your end. I've only seen you two get that working now. It's really rare I can gather!

I've been tinkering on and off a little but not gotten my Micron Rev.E to improve that much.

I've gotten 4333Mhz 4x8GB to work error free but it has cold-boot issues. A major hassle to get it to work/train from cold. Horrible timings etc and performance was basically equal and worse then the less hassles 4266Mhz I've been using for a while.

I got my RAM cooling installed and I've tried 1933 but no luck with that but I managed to squeeze 3800 CL13, 23, 17, 17, 30, 67... 590 1T Geardown:disabled. 1.680V, CL14 only needs ~1.600V.

I've found rev.E don't scale well with voltage... Well they do. But voltage only improves you chances of lowering tCL. No other timings scale to voltage increases. It might allow you to push higher speeds but the other timings have to increase with the speed.
A little disappointing anyway.

4x8Gb Kingston HX434C19FB2K2/16 3466C19 1.2V (Micron E-die 16nm)

I agree there are several factors to be considered to see the gains from FCLK/UCLK/MEMCLK. I just do not think the gains are as great as people think they are. People are entitled to there opinion and I am in no way trying to influence people but just sharing stuff.

Added 1920x1080 with the video above and it is margin of error stuff in these games as you can get 5FPS-10FPS difference between runs.Just my opinion.

@Nighthog
It is certainly nothing I did to be able to hit 1933MHz on FCLK like gupsterg said , a few factors are involved.It is also not important to hit the 1933Mhz FCLk but can just be fun trying .I just happened to be able to hit the clock on more than one AMD Ryzen.

Thanks for the share of testing data, been interesting to see for sure .

Was there anything specific you had to do it to be able to run 1933FCLK? Or was it down to particular CPU & motherboards that could do it only?

No it just worked on 3600X and 3800X. I have not done anything special .
I have one of the cheapest motherboards - MSI X470 - Gaming Plus you can buy.
The motherboard has worked great from 2600X-3800X over every BIOS.I can not say for sure what exactly lets my AMD Ryzen 3xxx CPU run at 1933Mhz FCLK

Why does elmor look like Uncle Fester and Uncle Fester doesn't?

Things that make you go hmm..

Thanks for the great info!
