Checking 1.325V settings for the Ryzen 3700X at 4.2GHz with all cores boosted?
Your Ryzen R7 3700X with the MSI B450 Tomahawk runs smoothly at 4.2Ghz across all cores. The voltage reads 1.325V. Is that acceptable? You mentioned Load-Line Calibration videos and heard mixed opinions about voltage levels—some say lower voltages are better, others claim higher voltages can be fine. Based on the specs and your setup, 1.325V seems within normal range, but it could vary slightly depending on the motherboard brand. It’s not necessarily unsafe, though you might want to double-check with your specific board’s documentation.
Everything seems fine, but I prefer using PBO in Ryzen Master to avoid being tied to a fixed 42 multiplier consistently. You’ll usually notice improved performance with the adaptive multiplier from PBO, allowing higher numbers like 43 and 44 when you’re running just a few cores.
Great setup for the OC! If you're concerned about LLC, try Cinebench R20 and monitor CPU-Z to detect any voltage spikes. Also review HWinfo for the peak reading after a full test. ^^^ For gaming sessions, PBO works well for single-core performance, as most games don't demand 100% utilization across all cores. When you're doing rendering or other intensive tasks needing all 8 cores and threads, a 4.2Ghz all-core OC will yield better results.
If LLC isn't enabled in the BIOS, you should be seeing vdroop when under load. I'd need to check the other voltages in hwinfo64 to confirm. It seems cpuz is the mainboard sensor, not what your CPU is actually getting. Look at the sv12tfn CPU core voltage under load—if it's below 1.325, your CPU is likely safe.
The minimum SV12 Vcore voltage is 1.319V, likely sufficient after load. You sometimes idle above 1.325V, which should be acceptable in low-current scenarios; the stock settings can rise to 1.5V under such conditions. It might be wise to overclock your RAM as well—2666MHz may be limiting CPU performance.
You can check stability by monitoring system behavior and performance metrics. If everything runs smoothly without crashes or unusual activity, it’s likely stable. Keep an eye on temperatures, fan speeds, and power usage to ensure they stay within safe ranges.
