I had no issues running 4.275GHz at 1.1v in Cinebench R20 MT. Got 3875 for the 3600X.PSA for all-core OC maniacs:
With the new release of AGESA 1.0.0.3ABBA, it appears that there may also be some changes in the effectiveness of LLC settings when maintaining high static clocks. I ran CBR20 through the paces (again) and found that on my x570 Aorus Master, LLC settings of Turbo for CPU and SoC were no longer the most-effective way to stabilize the CPU. When using Turbo/Turbo I had to push ~1.344v (as measured by CPU-z) to get the chip running at 4375 MHz. When using LLC Normal (which is essentially, LLC 0 or LLC OFF) I only had to push ~1.32v to achieve stability at the same clockspeed. Due to vdroop, that meant 1.3625v in Ryzen Master. Scores were nearly identical between the runs (7835 vs 7832) so there was no observable clock stretching. Note that I used to have 4400 MHz stable, but aggressive RAM OC seems to have made it difficult - if not impossible - for me to stabilize at that speed.
All above data is assuming no vcore offsets, either. I might try it again with -.1v offset and see how it goes.
edit:
I added a -.1v offset to LLC OFF to see how it would go. Some interesting bits.
When moving up in clockspeed to 4375 MHz, behavior with the negative offset was about the same as just running LLC OFF without any offset at all. CPU-z reported that stabilizing 4375 MHz in CBR20 required ~1.32v with a score of 7821. Temps were about the same as well (65-66C). The interesting bits happened at speeds of 4300-4325 MHz: I got those speeds running at stupidly-low voltages. 4300 MHz only required ~1.236v (actually closer to 1.24v). Most of my previous testing has required around 1.25v-1.26v to stabilize at that clockspeed. The chip turned in a score of ~7670 on several different runs with a reported temp of ~58C. Higher voltages did not improve score (but did raise temps). Needs to be some more testing done to research the effects of LLC + offsets.

Also, I think Maxon is still using a different codebase for Cinebench than they do their commercial Cinema4D software. Could be wrong. Has Cinema4D even incorporated Embree yet?
well, I have 2 3900x's at 4100 all core 24/7 100%load. So 4.2 is not unreasonable. I did not even try for higher, as I am happy with the temps. You are going to need at lease a 240 AIO water cooler to keep temps reasonable if you do get 4.2. Oh, and I got one of those at 1.1 vcore.vnt
Embree is the default option in physical render, at least in r20, which is what my own stress test was conducted under.
Does your 3900x boost to 4.6? I would hope for an all core OC of 4.2, not really interested in boost. Is this likely when I finally get one?

I am running 62c now. My fans are always@100%. Maybe that the problem ?Maybe even better than 240, Before thinking better of it I had PBO and AutoOC on (was on by default) with my 3900x, stress testing the CPU with a H100i (240) it was thermally throttling from 4.1 to 4GHz after a couple minutes. Now my install might not be perfect, my silicon not the greatest, and I wasn't doing a 4 fan push pull from the H100 (can't do the with the cooler where it is at), I also wasn't manually clocking it to 4.1 (where I might have been able to use less voltage). But there was room for sustained with a good cooler just my 240 setup wasn't enough.
Also worth noting I wasn't using the corsair fans but was using 2 Noctua NF-A12x25 PWM fans.
Ryzen Master...which matched up exactly with what it said in the BIOS.What were you using to measure the voltage? I've found that CPU-z reports the most-plausible numbers (I admit, I haven't tried using a multimeter to confirm those numbers). Stuff like HWiNFO64 gives much lower numbers.

On the first use after installation, Ryzen Master copies the current processor parameters to create default reset parameters
‒ If the processor is first configured in BIOS to other than default parameters, these changes will be reflected in the Ryzen Master default settings
‒ If the processor is changed after Ryzen Master installation, Ryzen Master will notice and will advise that the default configuration will be reset to the new processor
‒ If the system BIOS is updated, please uninstall then re-install Ryzen Master to link supporting BIOS elements for Ryzen Master to use
‒ If you have favorite profiles set up, use the profiles Export feature to save them, then Import them after re-installing Ryzen Master
‒ These steps will assure that Ryzen Master is accessing the correct information for the new processor and new BIOS
Well, that may explain some issues I've been seeing with my computer. I'm on a 2200G + DS3H B450 with G.skill Trident RGB 16GB/3200/CL16. I overclocked the RAM a bit, using the DRAM calculator (only to 3400/CL16), and then started running into Windows BSODs and weird issues (like my sound not working, only a full Windows re-install fixed it). Now, I still get the BSOD (edit: with various stop codes, not the same one). It could be that I need to reset my BIOS settings. It could also be that I have a crummy motherboard, as my wireless keyboard and mouse drop-out and I have to unplug and replug my USB transmitter roughly daily. The DS3H was open-box. I'm starting to think there was something wrong.Just in case some end users haven't read the user guide I'll quote a section of it.
The above is from the Quick Reference Guide
I'd imagine that it's not the only app that could have potential issues after a uEFI update.

That's weird that they want you to re-install it. It's been screwing up voltage readings from day 1 for me though, so I don't think uninstall/reinstall is gonna fix that.
I have a Corsair MP600 V4 on a x470 board. The only benchmark i TRIED RATED IT 4 TIMES BETTER THAN THE BEST..I went ahead and ordered the Sabrent Rocket 4 1TB NVMe SSD. I will test it and see what speeds I get, but I figure it will be a good upgrade for my 950 Pro either way and it was such a good price.

It's weird, but it at least sounds plausible in the end. If nothing changed between uEFI versions then what would really be the point of updating them. If Ryzen Master only scans the uEFI on 1st activation then I could see this potentially causing issues for the end user. Guess it's one of those better safe than sorry things.
I don't remember which thread it was, but there was a user that said Ryzen Master took over his uEFI and wouldn't let go of some memory settings if I remember correctly. I believe he had to uninstall Master an reflash the uEFI to regain control.
I'm guilty of not removing and reinstalling Ryzen Master after a uEFI version update, but I have noticed some strange behavior with it after a uEFI update.
Pretty sure it's showing VID in Ryzen Master, and not actual applied vcore.
You can see this by setting a -0.100V offset in BIOS and then viewing voltage in RM vs CPU-Z. CPU-Z will be "correct" versus RM. But the only real way to see actual voltage would be to take a DMM to the right solder points.
