Just a few findings from my last week and half with this motherboard, and I'm on the latest 1.63 BIOS The voltage reported back to most tools in Windows seems to be half of the CPU voltage set in BIOS. I get ~0.65 in CPU-Z, HWMonitor, AIDA64 with my voltage set to 1.3V Temperature in tools also seems to be lower, but the temp read back to AIDA64 for CPU Diode seems to match up with Ryzen Master

| " rel="nofollow - Think Voltage in CPUZ is dividing it in half so its whatever goes to either CCX or something? |

Maybe. Ryzen Master also doesn't report correct numbers when its just monitoring things when I look at it there, as CPU voltage just seems stuck at 1.18. I'm more concerned that most Windows monitoring tools are sort of useless right now.

| That could be true, but other (ASUS) boards I've seen posts for online show CPU-Z with the correct voltage; pictures showing actual voltage. So, this is probably an ASRock issue and hopefully will be fixed in BIOS and will not be a limitation of the board or chip implementation. I've seen posts on the TaiChi above and I've seen this same issue on my B350 Pro 4. It's not a utility, but a MB issue. |

| Yeah. I've emailed them and created this thread so I really hope they see it. |

One last post for now, but there doesn't seem to be anything on the internet saying what 1.70 is. If you go to the BIOS online update you get this... |

Dear ming3r, Greetings, this is ASRock TSD. This model has a PWM control IC to adjust the CPU related setting, so the VCore may not be the same if the reading location is different. For AMD Ryzen Master, it read the CPU voltage from CPU internal voltage. If other tools read the voltage from PWM IC, it would show the different value because the reading location isn?™t same. We would suggest user to observe the VCore by our official A-Tunning utility directly. http://www.asrock.com/MB/AMD/X370%20Killer%20SLI/index.asp#osAll" rel="nofollow - http://www.asrock.com/MB/AMD/X370%20Killer%20SLI/index.asp#osAll Thanks! All the best, ASRock TSD |

Thanks for the response! I didn't find the tuning utility before but it looks like it was uploaded today. I'll give it a go
