I could never use PPM Panel, it never launches. It would be handy for me as when using Balanced power I get some hangs in firefox, whatsapp deskop, ans as soon as I move to high performance they disappear. Same used to happen with zen1.

Oh, it might be because you're using fixed OC.
PPM Panel needs P-States or Stock to work.

Nope, no manual oc! Never worked not even in the zen1 time.. might be very old windows installation..

So happy finally 11 days after launch Newegg had the 3700X for sale at MSRP. Grabbed one should have it on Monday.

I'm not sure if this is set by Asrock or if it's the nature of PBO, but enabling PBO dramatically raises the voltage the CPU sees under load to above what most consider safe. Running a small FFT P95 under stock conditions the CPU will be under massive load and only volts to around 1.28v. Cinebench C15 and C20 stay at 1.325v which is what I've read is the max safe voltage. With PBO enabled with motherboard specs, I saw a massive 1.375v during P95 and 1.42v under Cinebench runs. Perhaps this higher voltage is only temporary and it's working as intended, or maybe it's on Asrock's configuration of PBO. I'm going to leave PBO off though I think.

Which software are you using to monitor temps? Some pages ago I've pasted a link and a brief comment on the high idle voltages. The article says it's connected to the polling of monitor softwares.

https://www.techpowerup.com/257312/r...bserver-effect

"We have determined that many popular monitoring tools are quite aggressive in how they monitor the behavior of a core. Some of them wake every core in the system for 20 ms, and do this as often as every 200 ms. From the perspective of the processor firmware, this is interpreted as a workload that's asking for sustained performance from the core(s). The firmware is designed to respond to such a pattern by boosting: higher clocks, higher voltages," stated Robert Hallock, AMD's head of technical marketing for processors.

On latest offical bios (combopi 1.0.0.1) i had same behavior on x370 professional gaming. All core load voltages were around 1.38v. However when using manual setting instead of enabled all core load voltage was 1.35v when not limited by power. So apparently enabled has higher scalar value than manual setting.

Btw. For what i have read max safe voltage is around 1.375-1.38v on 2000-series for all core overclocks.

Guys again idle voltage is high it's 100% normal and fine and under warranty what is not is PBO and so forth. Under light load our Ryzen 3000 chips will run at high voltage but if you run Cinebench or Prime 95 or some other test that stresses Zen 2 then you will see the voltage drop down.


Keep in mind temps matter more then voltage as long as you are running these chips around 90C or less on load you are 100% fine.

Control c control v from 1usmus post at dram calc thread:

"1) FCLK should always be equal UCLK and MEMCLK , otherwise, domain synchronization reduces system performance.

2) VDDG
3) procODT for all Zen 2 changed and the optimal range is as follows (for all motherboards) 28-40 Ohm. Settings from the previous generation of processors are not relevant (except for timings and voltage).

4) PB2 (+0 + 25 + 75 + 100 +200 mhz)not equal PBO. I advise you to use PB2, this algorithm does not depend on currents and thermal packets. The only limitation of this technology is processor temperature and FIT. Do not forget to turn off the PBO.

5) The optimal processor temperature for maximum boost is 60 degrees or less.

6) The maximum frequency of the memory controller (stable) in most cases is 1866-1900Mhz.

P.s. I have notified AMD of all existing problems, no need to worry.

P.p.s. Review. I have lost a lot of time due to thorough research of new products, but the review will already be published on all resources early next week.

BIOS 5.61

I like the slight redesign of 5.61 beta.

However, as someone else mentioned, disabling CSM results in no boot, at least on 1st gen Ryzen.

I am testing stability right now. If it is better, I will probably stay on it. Still, I hope they fix this in the next iteration.
