hi i want tell u some very important information about the p2.0 bios dont install it.

p2.0 bios not stable
smt disable dont work
cpu voltage controll dont work boost my cpu at 2,7V, at p1.60 bios 1.168V
qvl ram dont start with ddr4 3200, soc voltage 1.25V dont help to fix it .

i will try now how p.16 is working with OC/UV i hope it works fine.

bios p1.60 work very fine
ddr4 2933 with cl 14 timings work.

I'm noticed that CPU-Z often shows my CPU Vcore jumping over 2 volts also but HWInfo64 has never shown the Vcore as more than 1.4 volts, so I'm inclined to believe that CPU-Z isn't reading the voltage correctly.

Here's a screenshot of CPU-Z:

which is the opposite of what im getting Confused
cpuz stays very fixed at 1.296-1.312 in bios i have fixed volts at 1.30 with LLC level 2
hwinfo shows min 1.296 but current at 2.5-2.6

Are you loading HWInfo on startup or CPU-Z? I ask because I have HWInfo setup as my main monitoring tool and it starts with Windows. I expect that any other monitoring tool that is opened second will be the one that shows errant data values.

neither run on start up
ive just jumped back into bios and loaded setup defaults (eg pure and simple exactly as asrock would have any user run this board)
now everything should tickover at minimal volts but it still peaks over 2 volts when i click cpuz bench
just uploading the screen shot now
i will edit it on shortly
here the screen shot at 100% safe bios setup................... 'safe' LOL

so the question is

is bios version 2 for the taichi actually shoving 2.5+ volts into our ryzen cpu which is recommended to be 1.45 v max ?

on a side note due to another post about the graphics cards running at x8
i had a look at the version 2 bios concerning that setting on the tachi and nowits been changed to
auto/gen1/gen2 and gpuz reports mine running at 1.1 instead of 3 (ok update here it shows 1.1 unless i load the card with graphics task then switches to 3)

im feeling at the moment that asrock can keep this bios version2 to themselves until a stage at which they smooth out any bugs (be it false reports or actual dangerous settings)

my cpuz now reports between 0.5 volts and 1.1 volts depending on idle and running a quick cpuz bench while hardwareinfo has a max of 2.4 volts

this issue does need priority responce i feel
EDIT
ok ignore anything above this thread for recordings of cpuz
i was using version 1.78 and noticed you have later version 1.79 with ryzen support

now im much less happy
cpuz reports volts between 1.6 and 2.6 Angry

i have just posted this link to this discussion to bryan at techcity.tv who seems to know these baords very well and is indeed the guy we keep linking to with an overclock guide for the taichi
hopefully he can help with some insight and a view

Thanks for reporting this guys. I hope the insanely high CPU-Z VCore reading are wrong. I can't believe that they are right. Actually, I don't.

Just to let you know, with my X370 Killer SLI/ac board, using a 1700X, I see CPU-Z showing a VCore of over 2V at times, and values like 1.7V, 1.8V too. Running HWiNFO at the same time, I don't see a VCore over 1.280V, and the VID readings are 1.219V.

For those that use HWiNFO64, in the Sensor Status display, please find the VRM readings. My board shows two sets of VRM information, both whose title shows IRF IR35204 and the name of the board. One is for the CPU's VRM, the other for the SOC's VRM. It shows temperatures, VR VROUT and VRIN, etc. I imagine you'll get this with the X370 Taichi, and possibly more.

You can tell which of the two sets of VRM readings is for the CPU and SOC by checking the VR VOUT reading. The SOC VR VROUT will be ~0.900V or a bit less. The CPU VRM VROUT will be the VCore, which stays constant.

Here is an example of CPU-Z 1.79 and HWiNFO64 v5.51-3141 running at the same time. Please check the VRM VROUT readings compared to what I captured at the same time from CPU-Z:



I've modified the title/heading of the VRM data readings in HWiNFO, so it won't exactly match the default titles. I have the VCore set to 1.28125V in the UEFI, a preset value.

The CPU VRM IRF IR35204 VR VOUT reading of 1.279V closely matches my VCore setting of 1.28V in the UEFI. Above this I have the VCore reading in bold, whose maximum is 1.280V. I have CnQ and C6 enabled in the UEFI, which I assume accounts for the low Minimum and Current VCore values you see.

The CPU-Z VCore value was not static at 2.560V, but I caught it at that value with Windows Snipping Tool. I wanted to show you that I get that with my board too.

If you take the VR VOUT value of 1.279V and multiply by 2, you get 2.558V. Multiplying the Maximum VCore value I have of 1.280 by two, is exactly 2.560.

CPU-Z 1.79 which is pretty new, is the first one to support Ryzen. CPU-Z 1.78 would not even start on my Ryzen PC, it would lockup at 65%, and could not be killed with Task Manager. HWiNFO64 has had the ASRock Ryzen boards supported for weeks, with only minor updates to support specific boards from various manufactures. Personally, I trust HWiNFO64, since so much of its Sensor display matches what I know should be correct.

Sensor readings are not always direct readings, they are digital data and must be configured/calculated to get the correct reading to display. A reading being wrong by a factor of 2 or 1/2 is a common mistake when preparing a data reading for display. For example, it took CPU-Z several attempts/releases to get the Intel Haswell processor VCore reading (with that processor's on-die voltage regulators) right. IMO that is what we are seeing here again, a mistake in CPU-Z.

Do you really think your Ryzen CPU could survive having 2.5V+ applied to it for even a short period of time over and over again? I don't.

You can of course verify my readings and few calculations for yourself. I'm just reporting what I see in HWiNFO64 vs CPU-Z. Believe me, I am relieved that, IMO, the CPU-Z VCore reading is wrong.

So go ahead and tell me why I'm wrong... Ouch
