I think I will go back to 5.93
When I start my PC from no power it boot for few seconds, then shuts down and starts again normally.

Also I don't like that VRM reports high voltage at all times, didn't happen before. Maybe that's where I get my small performance boost from.

VRM voltage under 5.94

Your VRM temps are low like mine. I guess that is what I fixate on, so I don't recall past voltages. Mine are like yours though. Is that bad if temps are low?

As I understand the VRM output is that it supplies voltage to the voltage regulator that then passes appropriate voltage to CPU CORE VOLTAGE or SV12 TFN. So if it is relatively high, it is readily on demand for the kind of voltage peaks used by Ryzen cores in short durations. Thus, as you state, it maybe why we get better bench scores.

I don't know, it just feels like VRM doesn't mean much and CPU does all the job internally now.
VRM acts as a stage 2 PSU that converts 12V to 1.4somethingV with Vdroop control through UEFI settings. ¯\_(ツ)_/¯
My voltage under load was actually slightly lower on previous UEFI with same LLC, Scalar and Offset settings.

I guess it's just what AMD assigned them to be, except that my first core is marked with gold star in Ryzen Master, not the 4th or 6th.
But if I set my Minimum cores to 50% in RightMark PPM it will have cores 3 4 5 unparked at all times with core 0 1 and 2 unparked when necessary.
So it appears like even you have a stronger CCX and then a weaker one i thought the 3600's would all be pretty much the same.

Edit

Yeah man 5.94 does that to me too at times where it wont even boot right just like 5.91 but 5.93 works 100% perfect guessing if we compare hardware their is a reason for this

Also to clarify, the first column is just @1usmus power plan only, the second is @1usmus power plan plus Auto PBO, 5x and 50mhz scalers.

3800X Kernal Processor Power %

CCX1 1usmus PBO 5X 50 MHZ

Core 0 134 136
Core 1 138 140
Core 2 138 140
Core 3 130 132


CCX2

Core 4 127 129
Core 5 116 118
Core 6 123 122
Core 7 120 122
Thanks a LOT man, so i'm confused by all of this since my numbers are higher how can you get such great results don't you have 4600mhz even with Auto OC?

Also turning Auto OC to 50mhz instead of 25mhz brought all my numbers up by 1% haha

AM4 platform updates

AMD has recently released a new AGESA for vendors, version 1004. With more than 150 changes, this is a significant milestone in the evolution of the AM4 platform. We wanted to share some background information to support our release, and in particular ahead of the launch of the AMD Ryzen 9 3950X processor on November 25.

AGESA 1004 is designed primarily for stability. Here are the key information you need:

This is the only AGESA validated and recommended version for the AMD Ryzen 9 3950X. Your motherboard must have a BIOS with AGESA 1004 for complete and proper support.
It adds the final support for the "Eco Mode", which can be accessed via Ryzen Master. The Eco mode brings the AMD Configurable TDP (cTDP) technology to the 3rd generation of Ryzen. With one button you can operate a 95W / 105W model with 65W or 65W models with 45W. This feature was especially fun with the 3900X - 12 cores at 65W! We know that some of you have been very interested in a configuration like this, and now you can get it at the touch of a button.
AGESA 1004 is the "Big One" that reunites the codebase for all AM4-compatible processors. 3rd Gen Ryzen has been a fork in the mainline so far. So, if you have an older Ryzen CPU and have been waiting for an important AGESA release: that's it! This allows motherboard vendors to unify their CPU and chipset support lists on a codebase.
As an important stability version you are undoubtedly curious about the most important changes. Here are some of the greats:

AMD X570 stability and compatibility with peripheral devices.
Enhanced interoperability of PCIe, USB, SATA, and device reset features.
Additional improvements for the support and stability of PCIe devices.
Improved system stability when switching between ACPI energy states.
Improved POST / boot times. This varies depending on the motherboard.

There are also two performance improvements: improvements in the fastest core utilization and further frequency optimizations for the AMD Ryzen 9 3900X.
Due to the size and complexity of AGESA 1004 and the extensive regression testing required for older motherboards (unified codebase), the quality assurance and release schedule for older motherboards should take several weeks to complete. Newer motherboards like AMD X570 have already released releases in the last two weeks.

I marked what the numbers should look like i'm going to email Amd and Asrock about this to see if they are working on a fix i suspect this is why users aren't getting the right turbo's on worse binned units

I'll try to set a fixed voltage to like 1.38 or 1.35 and see what happens to SVI2 TFN Core Voltage and VR VOUT.
__________

Interesting, 1.35V still boosts to 4.3 as before, Vdroops to 1.325 under load. 10W less max power consumption, hmmm. I'm encoding a video with x265 in HB for stability test.
I wonder what would be a good single threaded stability test for that, it seems like that voltage is pretty stable for all core.
Will try to set core affinity for encoding and see if it crashes.
__________

Tried setting 1.3V, BSOD almost instantly after full load in Windows. Guessing clock stretching is not a thing anymore XD.
1.325V is not crashing but performance went down, so I should probably expect some errors in OCCT.
__________

1.35V random reboot. Won't bother with fixed voltage anymore, not really worth the time.

Flashed back to 5.93...
4.3 is being hit pretty often here while browsing/watching youtube videos

do you have those 1usmus's options for his PP enabled even if you are not using that PP?
