Ok guys maybe someone can explain what's going on. First of my specs are:

CPU- Ryzen 1700x
MOBO- MSI X370 Gaming pro carbon
GPU- GTX 1080
RAM- Corsair vengeance LPX 3000Mhz 2x8gb
PSU- 650W EVGA G3

I updated my bios from version 1.4 to 1.5. This naturally erased the overclock I had previously so I set the multiplier to 3.9ghz with everything else set to auto. I booted back into Win10 and evrything was ok just like before. Given the bios update incluided memory stability improvements I decided to try getting it above the 2133 it's been running at. I set it to 2667 again everything auto and it booted fine. It obviously wasn't stable because when I restarted the pc to go back to bios it did a memory reset. So I adjusted the RAM voltage to 1.35v and it just did a memory loop. So it put it back down to 2133mhz. Here's the confusing bit. Any time I either adjust the voltage for my CPU or RAM bios shows my OC at 3.9ghz Windows then shows 3.4ghz CPUZ and Ryzen master show the same. Not to mention the bios, Ryzen master and cpuz both show that the voltage adjustment has no effect. Anyone know the reason for this?

I reset my bios and applied the 3.9ghz OC and left the memory at 2133 until the next bios update.

The next bios update will have the AGESA 1.0.0.6 in it from AMD and is supposed to help Hynix chips support, although mine are Hynix and I dont have any problems running mine at full speed.

Anyway, onto the problem, whenever your bios resets like that, although the bios says 3900 for your cpu, its actually quietly reset that too, so what I do is I dial mine down to 3800, reboot back to the bios, set it back to 3900 and reboot, its fine then.

With regards to your ram, have you tried to raise the NB (SoC) voltage a little, mine is currently set to 1.100v, this helps a lot with memory overclocking, I also have LLC for the CPU at level 4 and LLC for the NB at Level 5, you and me have the same board and chip.

I would but it seems when I manually set a voltage it never actually takes hold. Even with my overclock if I manually set it to 3.5 volts and boot back into the BIOS it says its at 3.6. The same thing happens with my RAM. When I set the voltage to 1.35 volts and boot back it shows something completely different. I'm not sure whether I had this issue before the update. I didn't pay that much attention.

I just loaded XMP profile for my ram, left everything else alone, excpet ram voltage which I set to 1.37v

For the CPU I set 1.375v for 3.9ghz, pretty much sits there, I think it says something like 1.374v in the bios, but thats good enough.

and for the CPU NB voltage I set 1.100v and I think that sits around 1.098v again, close enough.

Set LLC level 4 for the CPU and LLC level 5 for the CPU NB.
On my MSI B350m Mortar motherboard, I needed LLC level 2 for the CPU to keep the voltage locked, but didnt need anything for the NB, it just sat stable at 1.100v all day long, however, last night when I ran IBT on my Pro Carbon X370 motherboard, I noticed the NB voltage was drooping, so I started playing with the NB LLC in the bios until I could run IBT without any drop to voltage at all, came out at level 5 for the NB.

After flashing the bios, did you clear the cmos with the jumper on the board ? this clears any conflicting data between the 2 bioses, (previous and new), ive had all sorts of weird and wonderful problems with boards in my time from forgetting to clear the bios after a flash.

Yeah I cleared CMOS as soon as I started getting conflicting voltages and saw when I reset my OC it wasn't showing in windows. After the reset my OC held but my voltages are still weird. I may have to play with the LLC's a bit they're still on Auto so that could be my issue. When I set my XMP I get a RAM boot loop so I'm hoping the next update will allow me to use either XMP or at least it's rated speed with looser timings. I've even tried the new try it RAM feature and none of that worked but it'll get there. The extra FPS and speed won't be noticed except in benchmarks and maybe a few FPS which I won't exactly feel with my current specs.

Try this please, enable XMP profile 1 which in your case will be 2933mhz, set ram voltage to 1.35v, set NB voltage to 1.100v, and change ram speed to 2666mhz, save and exit, see if that works.

Won't hurt to give that a shot. I'm finishing up a YouTube upload which should be done in a bout 15 mins. After that I'll give it a shot.

No luck. I set everything up and still get the boot loop. This time the voltages at least stayed in the ballpark of where they should be when manually set. I played with the NB LLC but and had it sitting at 1.104 which is dang near perfect but still got the boot loop. I guess I'll just have to wait for the next update and see if the situation improves.

Sorry about that, it was worth a shot, doing it that way used to work on my Gigabyte motherboard when I was experiencing the same problems as you, the next update or 2 should fix everything, it will have AMD's update in it too.

It was worth it just to see my voltages actually be where they should when I set them. Not sure why I was getting that issue but it was concerning. It also gave me an idea of where to start with LLC when I buy a better CPU cooler. I want to try and get above 3.9Ghz but I need tighter voltages for that and of course a cooler that can handle it.
