normal,,,for me it's the same (1700X)...it's simply XFR...if you disable it in bios, voltage spikes are no more..
voltages higher than 1.35 are dangerous in FULL LOAD....when all cpu cores are at 100% of utilisation....if you see, when load in the CPU grows, voltage drops
Voltage is typically related to current draw. Lets say core one is at rest, 2.2ghz. Then suddenly it gets called to do a very heavy task, it will require a spike in voltage to supply the sudden heavy requirement for current to bring the core from 0% workload to 100% workload. Though I admit that 1.54v is a bit high, what Vcore offset are you running? I will also mention that sometimes you will get an erroneous reading in HWinfo when you first launch it, I have seen a 1.590v max Vcore once and frankly I did not believe it.
Are you running a manual overclock? XFR will only work if the cpu is set to auto.
That 93.3C max temp is a bit high, what were you running to get that temperature? It may also be a symptom that your Vcore voltage (either manual or offset) is too high. The only time I saw temps like that was when I was pushing my 1700X to the limit in a overclock with close to 1.6v on the core.
The 93.3C is with the 20 degree offset. The real max temperature I hit was 73.3C with a full load. I'm on liquid cooling so temperatures rarely go above 65 degrees. Everything is on stock, all my motherboard settings are stock. I'm not even sure what V-core offset is, but I think it's all on Auto. All I did was update my motherboard to the most recent BIOS, and enable A-XMP to 3000 mhz which is what my RAM is rated. It boot up completely fine with no issues at 2933 (which is what Ryzen supports). I normally never see 1.544, usually 1.533 max, once in a blue moon I guess. I see XFR occasionally pushes one core to 4.1 GHz for a few seconds when it hits 1.5v+ levels. If you guys say that's normal, then I'll probably just keep the CPU since everything's been running well.
