Ryzen 5 1600 Voltage

[Nocte]

Hello,

 

I have noticed on HwMonitor that my stock Ryzen 5 1600 often goes up to 1.45+ v. This is done automatically as voltage control is set on auto in the bios. 

 

Is it normal considering that I did not Oc the CPU? It seems fairly high as 1.45 should be Ryzen’s max voltage for higher overclocks, while my CPU goes at most at 3.6GHz when turboing (but sometimes with voltages higher than maximum). 

 

I am just afraid about ruining my CPU.

1.45 is a lot. Update the bios. What mb do you have

If you are going to do OCing you should probably get an X processor. It has more GHz and has higher TDP for better OCing. Just don't buy a CPU with a TDP of something crazy. Other than that I am no expert overclocker but I know that 1.4v+ is dangerous territory, my friend.

auto voltage is always crap. If you dont want to OC, then just go into bios and lower the core voltage as low as you can wit hit remaining stable. my 6700k runs 1.268v on auto  Vcore but with manula tuning its perfectly stable on 1.15

no if your going to be overclocking you shouldn't buy a an x processor

exactly, if you are smart you would buy the cheapest CPU at your desired core count and then OC it, will prob out preform stock X sku. Also @DaRedBoi stock TDP has litteraly nothing to do with overclockability

It is only an extra 10$ with better performance. If you don't have a cooler than definitely get 1600.

My motherboard starts from Auto and then goes to +0.012, ... and increases. I have found no way to undervolt.

That’s what you get for buying Biostar I guess... but I had no choice at the time with ITX boards.

EDIT: Before getting any other responses about my processor, I owned this for over 4 months now. It’s not a question about whether the 1600 is good for overclocking or not. 

 

Plus, I DON’T INTEND TO OVERCLOCK

i think you are trying to use Voltage offset which will only let you go up. If you put it in manual mode then you should be able to input any value you want

I will give it a better look tomorrow evening. Thanks for the reply. I was indeed using P-state configuration, but having never overclocked a CPU I wasn’t entirely sure where I was putting my hands (and Biostar’s bios is a labyrinth to navigate). 

 

I will quote you again tomorrow if I have any trouble with it next. Thanks again.

Asus has great quality mobos. If you ever need to choose between Biostar and Asus, go with Asus

Asus does not even have ITX AM4 motherboards available right now...

[DaRedBoi]

Im just saying......... If it was ATX then you should go with asus.

If you're on stock settings, your CPU will automatically boost the frequency from it's stock 3.2GHz to 3.4GHz (all cores) to 3.6 (three cores), and 3.7GHz due to XFR (one core). Your auto voltage will increase to handle this performance boost. This will only happen if your temperatures are low enough. So you're perfectly fine. I would assume when all 6 cores are completely idle, your voltage is fairly low?

 

Edit: You may have an option in your bios to disable XFR, which may help some. It may be called Core Performance Boost.

Can you not hit the - (minus) on your keyboard with the offset selected and go backwards?

[donalgodon]

I was also surprised by the stock voltage jumps, so when I played with the best setting my Ryzen 1600 is stable at 3.7 GHz down undervolted to 1.15v and it's about 4-5 degrees cooler as well.

The Biostar BIOS makes you select the voltage from a drop-down menu list. I guess this is done due to the fact that the CPU power connector is 4-pin instead of 8-pin and want to limit people’s ability to do crazy overclocks. But they dumbed this down so much that even downclocking doesn’t seem an option.

 

Do you think switching to AsRock’s Fatal1ty ITX motherboard wouldbe worth the hassle + the ~140€? (Or even the Asus Strix ITX that has been re-announced a few hours ago?). Or should I just stick with what I have? I mean, if the CPU is safe with the auto-voltages then it’s ok, I don’t want to do any overclocking (my Cryorig C7 doesn’t leave enough thermal headroom for it anyway).

I see. I just looked up some screenshots of the bios and it seems very basic. About what I'd expect from Biostar, sadly. Not being able to undervolt the CPU is crazy. I do agree with you, however, 1.45v is incredibly high and isn't needed. Board manufacturers tend to be very liberal with the default vcore, making it much higher at Auto in order to support all the possible present and future CPUs that may be used. All CPUs are different. Even one of the same model may require higher voltage than another. But there SHOULD be a way to undervolt. I wonder if their most recent bios update would address this issue.

 

I know you said you have no intention of overclocking, but considering your Ryzen 5 1600 overclocks itself by default to 3.4GHz on all cores (mentioned previously), you could enter a manual 3400 or 3600 overclock in the bios, changing the CPU Core Voltage from Auto to it's lowest offset (I think +0.020). Then, if you're able to locate and disable the Core Performance Boost bios option, I think your vcore should stay way below 1.45v as it would have no reason to boost frequency/voltage so high. If for no other reason, this could be a temporary test to see what the Auto voltage actually is in Windows. I'd be interested in seeing what the voltage in Windows reports as Auto versus +0.020.

It doesn’t always stay at or above 1.45. It jumps between “normal voltage” to those numbers depending on the clock of the cores. 

 

But thanks, I will try to do what you mentioned.

In the end I noticed that I was reading the wrong tab in HwMonitor. VCORE never surpassed 1.24v even when all cores where turboed at 3.4GHz.
