What is normal behavior for CPU Core Voltage SVI2

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I put together my 5900X, Asrock b550m Steel Legend, Artic Freezer 420 aio.When I'm not gaming the vids are usually 0.9 - 1.1 V. My idle temps are always around 35 - 40C. But it sounds like it's CPU Core Voltage (SVI2 TFN) that I should be paying attention to.

My CPU Core Voltage (SVI2 TFN) is usually around 1.3 V even at idle. It can dip to 1.29 V but usually goes back up pretty quick. I tried closing everything like Corsair ICUE, Logitech GHUB, etc. but it made no difference. I checked CPU-Z and it usually shows around 1.0 V for core voltage.

I'm running the latest Asrock bios, latest AMD b550 chipset drivers, windows balanced power plan. I also reset bios to default and it didn't really lower CPU Core Voltage (SVI2 TFN).

Is this normal behavior for CPU Core Voltage (SVI2 TFN) for 5900X despite VID's and vcore being low and idle temps being low? Or should it be dropping as well and something isn't set right?

	Yes, most probably, because always one core will still be active max mhz in order to be able to quickly response to whatever you want to do next.... less complain from users of lack of response..... that's the one core that's using 1.3v+ but I don't remember if it's svi2 tfn or not. You can find out more by using/creating a POWER_SAVER plan but must modify processor max % to the lowest which is 5%?�i.e. minimum processor 5% and maximum procerssor 5% also. This will make CPU not boost at all and be around 2000mhz or so.... and cpu voltage will be as low as 0.9v, then check SVI2 TFN to see if it drops...Microsoft's original power saver plan still have maximum processor at 100% which will not drop mhz and will not drop cpu voltage to 0.9v, hence must manually modify maximum processor to 5%. and also try to use high permance plan to monitor the svi2 tfn.
