I don't get it. I use p-state OC via the ASUS software tool for my X370-Pro and my cores downclock individually to P1 states (which I have at 2.4Ghz).

Is your machine properly downclocking to your P1 frequency?
Ok, almost the exact situation as mine. However, I did raise the clock on P1 from 2800 to 3200, simply because the unchangeable 1.05 voltage left a lot of wasted headroom.Yep as long as I leave VID at stock everything works. I'm also only adjusting P0 frequency.
Yes, but if you can't lower the voltage, why not make the most of it? Raising the clock doesn't incur the costs of raising the voltage -- and it increases the situations where P0 isn't needed. So, having a higher P1 (without a high voltage) decreases the use of (the high-voltage) P0 and therefore reduces power/heat/wear on the CPU overall.Isn't the point of P1 to downclock and reduce power/wear on the CPU?
Good point, makes sense. Thankfully the ZenStates program allows me to change the voltage as well.Yes, but if you can't lower the voltage, why not make the most of it?

I got it.
C6H has a scratch... what to do? RMA? I need PC now...
Well, I set up the rig on saturday, only to find out that my video card was dead. Only got it replaced today with a temporary 770GTX.The rig itself will be:
- CPU: Ryzen 1700X
- Cooling: Noctua NH-U12S SE-AM4
- Mobo: MSI B350 TOMAHAWK
- GPU: Recycled MSI 970 GTX (was hoping to replace it with vega, will see ...)
- Mem: DDR4 Corsair Vengeance LPX 16GB (2x8GB) 3200MHz CL16 1.35V (CMK16GX4M2B3200C16R)
- SSD: SAMSUNG 960 EVO NVMe M.2 500GB
- PSU: EVGA SuperNOVA 650 P2 650W, 80 PLUS Platinum
- Case: Fractal Design Define S

Other than the ludicrous post-time of the mobo, it works very well. Memory OC was tons easier than I was afraid of. Got 2933 MHz with the ancient bios, as soon as I enabled the XMP profile. Once I updated to AGESA 1.0.0.6 the XMP profile 2 just worked and gave me the rated 3200 MHz on auto! (didn't even try profile 1, no need )
On the CPU side, I played around but finally settled on 3800 MHz with everything on auto (with cool-and-quite enabled), as this is the most hassle-free and works well on pretty much stock voltage.
Withe the new BIOS it goes as low as 0.680v on idle. Normal benchmarks get it to 1.360v while Prime95 (large FFT torture test) goes up to 1.376v. The temps are ~65°C on full load in bencmarks (unless running a power-virus like Prime small FFT test, where it can go over 80°) In gaming workloads (Witcher III so far), they are about ~45°C.
I might manage to undervolt it a bit better manually, but already this seems quite ok for a 1700X, right?
I'm very very impressed with the CPU so far! Though the ecosystem itself is still a bit rough ... for instance, a buddy of mine got his Tomahawk and 1700X at the same time as i did and bricked his mobo just by updating the BIOS from windows (yes, it might be stupid in hindsight, but it has always worked in my experience). Luckily I learned from his mistakes and updated successfully with a pen-drive
Some quick benchmarks:
Out of the box (3.4ghz, mem @ 2133mhz, etc ...)
After minor tweaking (3.8Ghz, mem @ 3200mhz):
- Blender (RYZEN workflow): 0:28:24
- Cinebench: 1439
- Cpu-z (ST): 375
- Cpu-z (MT): 4191
Here is the CPU-Z validation link
- Blender (RYZEN workflow): 0:24:45
- Cinebench: 1621 (average with BG stuff running, best run 1695)
- Cpu-z (ST): 439
- Cpu-z (MT): 4742
- AIDA64 trial: mem-read 47.1 GB/s, latency 77.9ns

Now I only wish I had a decent Video Card (and curse all the miners!)
I'm not sure if this board even measures it, at least i haven't found a place to look it up fromGideon, what are your VRM temps like while running Prime, Blender, Cinebench, etc?

That's a good catch, thank you! Will probably lower the OC for now, as it's not really needed yet. At stock, the MOBO temp after ~30 minutes of Prime is 85° and system power draw 147W peak, (though ryzen master only reports 69° on CPU die). I can see that the VRMs get reaaally hot very quickly.Weird that it reports no VRM data. Looking at other posts regarding this board, it appears that others have had the same issue. Apparently most have taken to checking the reported motherboard temp as being as close to the VRM temp as they can get without a heat gun. Your mobo temp is really high, so watch out! Actually CPU temps seem pretty high too. Power draw doesn't look too bad though, only 199W peak.
