1.325v for Ryzen 3700X 4.2Ghz all core overclock???

[TrxBoy93]

My Ryzen R7 3700X with MSI B450 Tomahawk is stable at 4.2Ghz all core.... Voltage is 1.325v.... Is this voltage safe??? I heard about Load-Line Calibration (LLC) https://www.youtube.com/watch?v=NMIh8dTdJwI&t=8s where your CPU can get more or less voltage than what you type in bios depending on motherboard brands..... I heard that MSI boards deliver lower voltage and Gigabyte delivers more voltage than what was typed in bios....So is 1.325v is safe or in reality my CPU is getting 1.4+v ???

Everything looks okay, but I would rather just use PBO on Ryzen Master so you're not locking yourself to a static 42 multiplier all times.

 

More often than not you'll see better performance with adaptive multiplier from PBO as you'll get 43 and 44 multiplier when you're only using a couple of cores.

Hella nice voltage for that OC! If you're worried about LLC, run Cinebench R20 and watch CPU-Z to see if the voltage spikes, can also check what HWinfo reports as the max after a full run.

^^^ Also true. If you mostly game, use PBO, will give you better single core and there's not many games that will use 100% on all cores. If you're doing rendering or any other task that uses all 8 cores and 16 threads for a sustained period, a 4.2Ghz all core OC will perform better there.

If you haven't enabled/set LLC in bios you should be getting vdroop under load, though  I'd need to see the other voltages in hwinfo64 to be sure.  I think cpuz is the motherboard sensor so not what your cpu is receiving in reality.

Try to see what your sv12tfn cpu core voltage is under load, if it's under 1.325 which it probably is your cpu is perfectly safe.

1.325v wasn't stable.... 1.3375v was 100% stable...So I updated the voltage....New SoC voltage is 1.0v (i set it manually) on bios, 1.3375v for Vcore, PBO is disabled. Please check the screenshot for any abnormality...

OK the minimum sv12 vcore voltage is 1.319v which was probably under load so should be fine.  You're idling higher than 1.325 sometimes but that should be ok in low current situations, the stock settings go up to 1.5v under low current.

You probably want to overclock your ram too, 2666mhz is probably holding the cpu back a little.

would just enable PBO, you will get better performance in most if not every scenario.

how do you know if it's stable?i'm running at 4.3ghz 1.3v..everything else in bios are default/auto...seems to be working so far..=x..so mine's stable?
