Sup guys,
I have a question. I have a ROG Strix B450-f and I am overclocking my Ryzen 2600 to 4025MHz and I set manual voltage to 1.3V + CPU SoC 1.1V.
VDDCR CPU LLC - High
VDDCR SoC LLC - Regular
I'm using HWiNFO64 to see temps and voltages. My question is:
CPU Core Voltage (SVI2 TFN) reports in idle between 1.3V and 1.312V. Under load between 1.281V and 1.294V and I know this happens cause of LLC settings.
On the other hand, CPU Core Voltage under ASUS WMI shows values between 1.341V and 1.395V.
Should I worried with this last voltage? Or should just be worried with the SVI2 TFN voltage?
The temps are around 62ºC running blend on Prime95. I need to stress the system more with blend but I already did 2 hours of RealBench and 30min of blend.
The SVI2/TFN voltage is the internal voltage experienced by the CPU cores. The VCore measurement comes from the Super IO chip on the motherboard, taken at a location along the power path between the VRM and the CPU socket.
In extreme overclocking scenarios, it's important to monitor both values closely. Use the difference to understand load-line losses and achieve a balance between VRM and LLC output levels. Aim for some VDroop (due to load line effects) that helps minimize both...
The SVI2/TFN voltage refers to the voltage experienced by the CPU cores. The VCore measurement comes from the Super IO chip on the motherboard, taken at a location along the power path between the VRM and the CPU socket.
In the context of extreme overclocking, it's essential to monitor both values carefully. Using the difference helps gauge load-line losses and achieve a balance between VRM and LLC output levels. Aim for some VDroop (due to load line effects) to reduce both undershoot and overshoot during changes in load.
For regular users, the SVI2 voltage is generally the most critical thing to keep an eye on.
Yeah, I understand. Thanks. I'm going with a "medium" OC. I had to lower the clock speeds to 4Ghz because at 4.025GHz with 1.3V it wasn't stable. I also set the LLC to medium. Now I'm seeing 1.269V under full load and 1.289V idle, reaching a max of 1.306V in SVI2 TFN. It seems like going higher isn't worth it since I already dropped to 4GHz. I've been testing for a whole day so far and everything looks good.
