The RAM will work but you won't be able to overclock them. You'll like be limited to 2133Mhz, maybe 2400 if you're lucky.

My AB350 pro4 is running 2933 memory. at CAS14 no less.

It depends on the motherboard (not the chipset) and the memory. I have an ASRock motherboard, and the best Gskill memory that is supposed to work(and does) at rated overclock speed. (well, not up to 3200 yet)

Not surprising since it uses Samsung B-dies which have the widest compatibility. Hynix and Micron chips don't like the internal timings that the memory controller on Ryzen uses to get to the higher speeds.

He's running 4 double sided DIMMs though.
 
I might sound like a broken record, but I am concerned with the voltages. The temperatures now I understood from AMD's statement.
1.984 V shown by CPU-Z is insane. HWInfo is showing something else and Ryzen Master is showing another thing.
Please could someone tell me if the readings are OK, how can I have so much Voltage. In the BIOS I even decrease the voltage. If I am getting something defective I would like to return asap.

Which motherboard? Something is definitely misreporting the voltage (probably CPU-Z, 1.984v is 😱). Even 1.44 is too high for that clock speed.

EDIT: I see the motherboard in sig. Are there other reports of issues with the B350 Prime Plus, maybe a beta BIOS you can try? It's possible the CPU is "bad", but given all the issues ASUS and other manufacturers are having, I'm inclined to rule out the motherboard first.

When I down-volt in BIOS the system freezes. So in the BIOS I have to set it at least 1.25 V just to ensure I am not providing insane voltage to the CPU until ASUS sort this out.

Now I am digging more into this, in the Ryzen Master Manual

Note: Some motherboards may apply a voltage offset from the BIOS. In this case the actual CPU voltage may be higher (or lower) than what the CPU VID value suggests. It’s always a good idea to monitor the actual voltage level (from the BIOS or with the motherboard vendors monitoring application).

When I took the plot of the VDDCR_CPU during an AIDA64 Bench Run, there was a spike to 1.40 V after that it was around 1.2V. Using ASUS AI Suite, [They updated it] I got the plot below.

So the default CPU Voltage settings in the BIOS is 1.4 V. Now I undervolt to 1.25V. It seems stable.
I go in the BIOS and the CPU Voltage is also ~1.3 V.
But it is not clear to me that why the VID can really go so high.

Could someone please explain these spikes?

I believe I've read it is being misreported in software. 1.4V is actually safe but I bet if you could read it with a DMM (I don't think your board has DMM read points, unlike the C6H) you would see it is lower.

The other thing to try is to see if you can do 1.25V with load-line calibration level 1 or thereabouts, and see if your readings are more stable.
 
Cant seem to run anything over 2133 with my Patriot DIMMs and my Gigabyte AB350M. Latest beta bios F3c

I changed Load Line Calibration to Regular instead of Auto and this is what I got after running some AIDA64 Bench. It is always around 1.15 V

It helps a little I think. I will observe it for a while.
 
Well mans I need your advice. So I'm going buy Ryzen rig. Now i have HIS radeon rx480 8g, i've ordered G.skill F4-3000C15D-16GTZ (during shipping now). And then I've to choose mobo. I want to slightly overclock up to 3.8 (maybe 3.9 if i win in silicone lottery 😀) and I hope memory will work on the 2933 or even 3200. If I right understand I need x370 motherboard. Preliminarily i think about Fatal1ty X370 Gaming K4 or Asus PRIME X370-PRO (170-180$ budget). I've seen in some reviews on youtube that just now bios on asrock more mature then on prime. It has more detailed overclock tunings. And moreover on prime if Ryzen overclocked - its frequensy became fixed and never go down even if cpu idle. What can you advice me (maybe other variants)?

The best is the Taichi from ASRock, but its OOS and will be for a while. The Fatal1ty X370 Gaming K4 looks Ok. DON'T get ASUS anything for Ryzen at this time.

Yeah,what Mark says!! Stay super far away from anything Asus unless you want a heck of an expensive paper weight.. 🙁

Most of the power savings for Ryzen when idle appear to be done at the hardware level. It was consuming less power at idle than my Skylake system even when set to high-performance mode and locked to higher frequency, telling me there must be hardware-level power savings at work. 97% of 1700 processors can hit 3.8GHz, and 77% can hit 3.9GHz, according to Silicon Lottery. So a 1700 is a great value.

Motherboards are a tougher question to answer. It seems that people are having good results with some B350 motherboards like the MSI Tomahawk and the Gigabyte AB350 Gaming 3 (the one with the ALC1220 audio codec). X370 is a mixed bag and I wouldn't recommend ASUS until they iron out their BIOS issues...

If you need the X370 chipset features then Asrock seems to have the best reputation so far in terms of BIOS updates and stability. Specifically the X370 Taichi, which is extremely limited in stock until late this month/early next month IIRC.

The ASUS PRIME X370-Pro is the best board for the price imo. Intel NIC, 1220 audio, X370 chipset, excellent VRMs. However, it has horrible support for memory at the moment and has issues with overclocking in general. I'm running it perfectly stable at stock for everything and can push my 1700 to 3.8Ghz @1.3v running handbrake for hours but it seriously needs some BIOS love. At the moment they're focusing on their flagship CH6 board understandably but eventually we'll get some BIOS updates for better memory support and better overall stability with BIOS adjustments.

The ASRock boards are seeing more BIOS updates compared to Asus and people are getting good results for memory as well so that might be a better choice for now.

The above suggestions to stay away from Asus are due to the Crosshair IV (CH6) problems with the boards killing themselves.

Also, I have the Corsair memory that is supposed to be good for 3200mhz, and it won't boot at all at that speed.

My GB Gaming 5 board will boot using that RAM@3200, but it isn't stable under multi-threaded load (Prime95 and/or my NLE). It's only stable at 2133 for me right now. Not entirely happy about that -- the RAM is on their list (well, the 64GX4M8, which is just the 8 stick variety).

CPU overclocked easily to 4Ghz with a voltage setting of 1.375 (I didn't try a lower voltage, and I haven't run it on a multi-hour soak yet, but I'm also on air, not water). 4.1Ghz was a fail at 1.4.

Looking into the threading details of my NLE, looks like it suffers from some kind of latency issue that prevents it from running its main threads at 100%. As a result, it requires high-slice encodings so that it runs enough threads to keep up to date. Unclear where that bottleneck is. That said, there's enough single-threadedness in various parts of a number of NLEs that unless the threadripper gets a serious frequency bump, I'm sticking with the 8-core for now. Running twice the cores at 2/3 of the speed is not appealing for my use case. It'll be interesting to see where Skylake-X frequencies land as well.
