Nice and shiny but 1/2 divider is useless considering IF delays is causing in memory access speed. It is only good for records breaking.

I hope is not just a marketing stunt then.

My 1800x OC
Win10 Pro / PRIME X370 PRO / 1800x @ 4.05Ghz - BIOS 4012
TPUII / 40.5x / 1.425v Vcore / SOC 1v
CPU LLC3 and SOC LLC3 / CPU and SOC Phase control = Extreme / CPU Current Cap. 130% BIAS=CB11.5 (CB15 score 1780)

Hi,
I want to overclock a bit more my Ryzen 7 1700 which is currently at 3.6Ghz 1.1875V + 3066 Mhz CL14 1.35V RAM. I want to ask you how far I can push voltages to prevent VRM/MOBO damage? (CPU / SOC / RAM). I managed to reach 4.0Ghz with 1.41V but it's quite high I think. I dont want to destroy MOBO's VRM due to thermal damage.
I also want to mention that I have 140mm fan which is pretty close to the upper part of VRM, but the other VRM part cooling is not as good.

Is there any advantage by updating BIOS to current version? I have pretty old one, but I managed to reach 3266 Mhz RAM frequency on it. I consider update but I'm also afraid that it can ruin my RAM stability or something. What do you think?

Rest of my PC config:
R7 1700 3.6Ghz 1.1875V / SOC 1.0V
Corsair LPX 3066 Mhz CL14 1.35V
Corsair H150i PRO
EVGA GQ650W

Thank you in advance.

I had my 1700x pushed to over 1.5vc and never even heated VRM up significantly, let alone do any damage.

It's also pretty hard to measure temps because this motherboard doesnt have a temperature sensor. So as you said, 1.41V seems okay for 24/7 usage?

Running 1700 at 1.41V on X370-pro all time. It is prime95 default test stable at 4ghz but only 3.7ghz at smallFFT with 60mm AIO cooler.
Both multicore numbercrunching code and new games run fine at 4ghz, no crashes, so default prime95 test is sufficient for my purposes and smallish water cooler.

It seems Prime95 and IntelBurnTest compete which one can degrade your CPU faster. SmallFFT test is excessive in my opinion, unless you run data processing code on all cores 24/7.

AMD say 1.425v is ok, degrading _starts_ at higher volts like 1.45 based on AMD predictive models. Haven’t seen real world burnout time vs. volts measurements. Probably these actual data would not be published.

Sounds good.

Is there any option to measure temps on MOBO without IR temperature gun? I noticed that MOSFET's are pretty hot when it's even on 1.35V. Can it bear with higher temps? Or maybe buying a small radiators for each of them is a good idea?

Apparently they can stand 100c but it's not only voltage that keeps them worm, high CPU usage does it even more. From the back of MB VRMs get even hotter.

I'm confused because currently it's on 3.6 Ghz 1.1875V and MOSFETs are not even warm (high cpu usage) but when I start to increase voltage over 1.35V I cant even touch it in full stress test. Probably finding the balance between reasonable voltage and CPU frequency is the best idea. Pushing it to 3.9-4.0 costs too much. Especially it requires about 1.45V to be stable with 4.02Ghz... in addition ~3.95Ghz needs only 1.35V.

What LLC and Power Phase Control settings are you using? Now I'm on auto/standard. (with 4Ghz I had LLC LVL3).

Too bad there's no temp sensor, 50c is temp where you can't keep finger on for less than a minute so it's pretty subjective value. How's your case cooling ?
