Ryzen 3600x, wont boot at 1.35v??
- Thread starter lettuce
- Start date
Any ideas why if i set a manual clock of 4.4Ghz (so no actual overclock) i need to set the voltage to 1.35v to get it to be stable when stressing Prime. If leaving vcore at AUTO it seems to go as high as 1.4v which is way too much
Unless there some options im missing in the MSI Gaming Plus Max BIOS??....i have tried looking for an OC guide for this mobo but haven't found one yet
1.35 probably is to much if you want to run prime all day long everyday but for lighter loads like gaming then even up to 1.375 is fine according to Der8auer.
I mostly agree, but have no idea about what uses he has in mind
Just general browsing, gaming and some video editing. As i said im not looking to go over what the stock clocks are, just wanted noticed the voltage when set to auto seemed high. Setting a All core clock to 4.2 and voltage to 1.280v still seems to crash the system when i ran Prime95
That's just how the voltages work on these ryzen CPUs, up to 1.5v for light SC loads is perfectly fine according to AMD, the heavier the load and more cores being worked causes the voltage to decrease accordingly.
Ok then, just a few were saying anything over 1.325 was not recommended.
with a vcore of around 1.325 @ 4.2 im able to run Prime95 for 20 minutes without issues and keeping below 81c......i may add a 2nd fan to my heatsink for a push pull config to get the temps a bit lower.
I am wonder if its best to go the route of what no idea what suggested on the first page and just leave the voltage on Auto and set an offset of -100 mV.
Just when leaving the vcore on auto HWInfo reports a Max of around 1.438v which seems alarming to me, not sure at what point it hit that though as when running prime95 its only about 1.243v average
I doubt it will be stable at -100mv, -.050mv maybe more realistic.
Your probably right.
Even at default BIOS settings the voltage it set the cpu is on the high side right?.....
If i set the CPU from auti to 4.2 does that also lock the single core performance to 4.2??. As leaving it as Auto the system isnt even stable at 1.35v, but setting it at 4.2 it appears to be stable
The advertised 4.2 multicore and 4.4 single core performance aren't guaranteed right?
You should atleast have 1 core able to hit 4.4 at stock although all core boost will probably settle between 3.9 ~ 4.2 depending on how heavy the load is.
Tbh at this point I'd probably just leave it all on auto and if you want to lower temps then manually adjust the CPU fan speed in the bios to spin up more once it hits 70C.

Yeah i cant see an option that relates to setting a single core speed.......unless thats the CCX option???....as i said im new to AMD
There is an option to boost single core speed in the PBO menu, it's called max CPU boost override but never seemed to do anything on my old 3600.
It does seem odd though as if i leave everything on auto apart from setting an offset of 0.050mV when start a Prime stress test the voltage according to Ryzen Master is 1.312v yet if i was to set this voltage in the Bios and even a bit more Prime would fail straight away
Probably because the CPU is automatically lowering the core speed during prime to maintain stability.
Well some head way appears to have been made!!!
So in my bios under the CPU Core Voltage, it gives you a few options:
AUTO
Override
Offset
Override + Offset
AMD Overclock
Before i never even bothered selecting AMD Overclock, but have tried that option and im currently able to boot into Windows and am currently stress testing Prime @ 1.27v!!. With Per CCX 38.00 & 40.00
Im not sure what this AMD Overclock option has changed from not being able to get stable @ 1.350v using the 'Override' option to now being able to @1.27!??
One thing i have noticed is In Ryzen Master, under the PCU Votlaage section the current voltage never seems to change and is always the same as the Maximum voltage
