Mines exactly the same but with a H100i, really not sure if the temps are acccurate.

I also have exactly same as you described earlier. In the bios CPU temp is 33c or something, vcore is 1.3, but once I load Windows, it's at constant 1.41 and 40-50c range.With a lowly 3600 on a Wraith Prism.

Getting ****** with AMD claiming it's purely observer effect and monitoring tools causing it. Clearly it's more than that.

Been reading this with interest and thought I'd add my findings on it. I'm running prime and the CPU volt goes from around 1.5 to 1.35 under load (CPUs goes to about 4.15 Max under load and 4.3 outside of full load). All done under PBO.
here it is under load.

My temps are the same as above (3700X), they seem all over the place. I've lost the use of my M.2 slots on my Gigabyte Arous X470, F40 bios. At least now I can run my ram at 3200mhz.

ok, just as I post it goes a bit funky. CPU volt now 1.1, CPU speed 3.7 temp @ 75 after getting close to 95, then it all started dethrottling.

Old Rig:
2500K @ 4.5, P67 board, 8 gb ddr3, custom water loop 2 x 240 rads
Vega64 which I bought at christmas and was obviously being held back
40" sony bravia 1080 tv as monitor
coolermaster cm690ii case
Corsair TX750 psu

Now:
3700x stock cooler
MSI 570-A pro
16gb Team group vulcan 3200 c16
vega 64
240 ssd boot, 480 ssd games, 1tb ssd for audio stuff
corsair 400c case
seasonic focus plus gold 750fx psu

Not messed with memory yet, just XMP @ 3200 with no issues

Still tuning clock
At stock seeing cores boost to 4350 with mid-high 80's temp under aida64 stress. r15 = 2077
@ 4.4 all cores / 1.4v r15= 2305 but temps getting to 95 on aida64 (aida64 failed below 1.4v)
@ 4.35 / 1.35 v temps max 92
current 4.3 / 1.325 v (aida64 failed with lower volts). been running now nearly an hour. r15 = 2263

Only gamed at stock so far and the only thing I play regular is ring of elysium. Massive frame improvement from 100-130 to 180-220

try prime 95. Mine had a fit after about 10 mins, otherwise my scores are matching yours.

I'm happy with the purchase, especially as it seems like AMD Ryzen Master is fun to play with. Managed to get the 3200 DDR4 upto 3600 with it nicely.

Ordered this to replace my 6 year old i5 3750k. My case is about 15 years old as well so went for everything bar graphics card as i have a vega 56. The Ryzen3600 just seemed to be stonking value. Should all be here tomorrow although i wont be able to build it till likely the weekend. Will have to flash the bios on the MSI board too no doubt but i see the MSI x470 supports bios flashing with no cpu etc. Wish me luck!!

Did you get your stuff? I ask because I don't see a flash bios button listed on the specs for that board on the MSI webpage. I can only find b450 boards from mis with the flash button on them.

Your CPU isn't doing anything in the BIOS though. There's nothing sinister at play it's just how these chips operate. To quote myself from the other thread.

I have a B450M Mortar (& 3700X) and after a whole evening of messing about with OCing, Firmware and Benchmarking I've some thoughts :D

Your cooler doesn't matter to be honest. The Ryzen power plans that come wth the chipset drivers are extremely sensitive and aggressive, they're often boosting to high frequencies for very small amounts of time. The voltage will drop for an all core load.

Ryzen thinks a small background task needs a burst of speed and supplies it, this is obervable in CPU-Z. Though it doesn't show you when the core goes back to sleep.

This isn't enough time to cool the die and before the CPU cooler has even begun to ramp up the frequency has dropped. This is why it's all over the place.

I have a Noctua NH-U12S and I've after much messing about I've just disabled the cooling fan until temps reach 65 degrees. The temperature and frequency fluctuations seem to be exactly the same, doesn't matter if the fan is 0% or 100%! See picture below.

It all seems part and parcel of how Ryzen 3000 operates. If you're worried about voltage put Windows Power Saver on and watch it sit at 0.9 volts, it'll boost all core but it'll take longer to get there.

Just to add to that, if you force close absolutely everything and make sure Windows isn't doing anything in the background you'll see voltage drop to below 1v. If you start a YouTube video the voltage will report 1.4+ despite your CPU utilization being 2%.

It's not worth stressing over, that's clearly how these chips are designed to work and is completely safe.

Finally up and running with everything brand new. Really pleased with this 3600 chip TBH. I was worried about doing this complete build as I have done anything PC related for a very long time. The only issue I ran into was no post to screen on first switch on but it was just a ram stick that wasn't seated properly. Every appears stable although still some testing to do. Not played with bios yet apart from setting the ram at XMP profile 1 to get it running at its default 3200mhz. Every thing else in bios is set at auto so any tips on what i should be looking to adjust would be appreciated.

Cpu temps seen OK but they are jumping around a bit and the cam software for the AIO is reporting temps at 50 degrees on the cpu and not moving so probably needs an update.

Feels quite nice to have a clean install of windows after all this time too :)








And just for reference my old trusty machine that has served me well for over 6 years (the case is about 18 years old).




The case behind it contains an Athlon XP2500 and is still fully working :)

Good post, not sure why people keep posting about idle voltages, it's just how it works, yes it's different than other processors so far. As above, adjust fan curve (so that it ramps up at higher temps), use only CPUz to read voltages (switch off everything else) and move along:)

12904 CPU score in timespy, pretty good by looking at Timespy thread, considering that it's stock and is loosing with heavily overclocked CPUs (still top10 CPU results)

Just replaced my 2700(non X) with a 3700x in my ASUS Strix X470 Mini ITX board with the latest BIOS.

I was thinking because they are both 65w chips I wouldn't notice much heat and noise differences. How wrong was I!

I think the hottest I had seen 2700 was low 70s. Like a lot of people my volts where 1.4v+ in idle. I have manually set the CPU voltage to 1.3v and now I have been running AIDA64 for 15 mins and it's at 84c and the CPU fan is at 1700rpm. I used to hardly ever hear my CPU fan getting that loud! My CPU Cooler is noctua l12

Is this just a issue with early BIOS? Anyone have any tips?

It's just how hot the chip gets, a bios isn't going to fix it. Different chip, different heat.

My 3700x hits 95 under load but that's at 1.45v with Prine95 when using PBO. Lowering to 1.35 and it hits around 88 in Prime 95 at 4.1 but my evo 212 is still silent

I think I've finally got my RAM stable at XMP 3000 MT/s. I noticed Ryzen Master was reporting the DRAM voltage as 1.325 V despite me setting it as 1.35 V in the BIOS. I've upped it to 1.375 V and now it displays as 1.35 V. I also changed VDDP in the BIOS to 0.95 V, however Ryzen Master shows that VDDP is still at its stock 0.9 V whilst VDDG has gone up to 0.95 V...clearly something is wrong there in the BIOS, especially as I can't seem to find an actual setting for VDDG. Seems fairly stable now though; it doesn't fall over within 20 seconds of OCCT any more.

In terms of temperatures, unless Ryzen Master is lying the highest temps I've recorded so far were using Cinebnech at 69 C. OCCT and IBT don't come close to that even after 5 minutes, which is odd.

Finally Aorus Master and 3700X arrived. Can't seem to post a picture on mobile. Not much to see so far as I need to find time to put it all together.

I think this is the problem for some of us with louder coolers. We're not used to having such high temperatures and fan noise for either Intel or Ryzen 2x CPU's for stuff as mundane as browsing the web.

As someone else said I'll just have to set a different fan curve and keep an eye on it really, though from purely habit the thought of a CPU idling at 50c+ while surfing the web makes me feel uncomfortable....as does the fact that I have to go messing with fan curves at all.
