Ryzen 3600x, wont boot at 1.35v??

lettuce · 3 Jul 2021 at 22:24

So im using a MSI 450 Gaming Plus Max with my Ryzen 3600x, ive change the vcore for the cpu from 'AUTO' to 1.350v in the bios but it wont boot into windows. I was under the impression i should be able to select a lot lower voltage than this with the 3600x??

You want to leave it on auto and use a voltage offset. Ryzen boosting needs up to 1.5v to remain stable. You can only set a manual voltage with a manual overclock.

Try setting the CPU multiplier to 42 and see if that boots and if it does run a couple of benchmarks like cinebench R20 etc then keep increasing the multi by 1 and rinse and repeat till you find the max frequency that it will run at.

Whats a good offset to set? 0.050???

So v1.350 is a good value to set or can it go lower?

You can go lower if you want, 1.3v is a good place to start at then when it gets to the point that it crashes in cinebench you either need to back the frequency down or up the voltage.

I set The CPU Ratio to 4.2 and i had to up the voltage to 1.3250 to get it to boot in windows

But i have noticed as ive set the CPU ratio to 4.2 its constantly at that clock speed and doesnt drop

It does down clock and sleep but you can only see this in ryzen master.

If it needed 1.325 just to make it into Windows at 4.2 then unfortunately it looks like you don't have a great sample. If you can't hit 4.4 with the all core clock at reasonable voltages then your probably best just running at stock else you will lose the single core boosting.

Tbh i dont want to overclock it just wanted to set lower temps so it would run cooler

What cooler do you have?

LOL

Its a Vetroo V5 Black. JayTwoCents did a feature on it back last year and was super surprised at how it performed. I gave it a punt as it was super cheap

So even at 1.35v Cinebench closes down!!!. Not sure if theres anything else i should be tweaking....

flea.rider · 4 Jul 2021 at 00:40

run cpuz .. whats the vid on the chip ? that will tell you the least you can set it at ..may be you lucked out on the silicone lottery and it needs to be run higher ...

That value just depending on what voltage ive set in the bios, its not a static value

Put your multiplier and voltage back to auto and boot into windows.

Start cpuz and check your cpu voltage.

Then do a Cinebench run while monitoring the max voltage you see in cpuz.

You're trying to do an all core overclock here.

Do as I did before and do a voltage offset on auto. You will have to experiment but around -100mV should help with temperatures.

What sort of temps are you getting as 60s~70s are pretty normal for the 3000 series and even in the 80s seem normal for the 5000 series.

Personally wouldn't run anywhere near 1.35v, put it back to default run prime 95 small FFT for 10 minutes see what you vcore has settled to, this is considered max safe vcore you should use

OK, ill set it back to default so everything will be on Auto and ill run Prime and post pictures

OK ran Pirme95 for 20 minutes....
