Voltage settings on 8700 non k?

[Thauner]

For you guys running with the 8700 non k. 

What are you're voltage settings? 

 

My cpu is having spikes all the way to 1.489 and think it's too high! I'm on an Asus STRIX-I gaming board. 

 

Never tried to set voltage or overclock for that matter, that why I bought nok k. But the temps seem a little high, so want to try setting the voltage. Please help 

 

I also tried to set maximum cpu state in power management to 95% and all worked very good with fine temps. But read somewhere that turbo boost then will be set as off.

Check if Multi-Core Enhancement is enabled. That might be messing with the voltages. Idk if non-K variants have that setting, but they might.

 

Disable it and report voltages if it's enabled.

Its off. I read about mce the other day, and turned it off. Nothing changed.

I got nothing then. I'm an AMD user as of right now. That's all I got. Sorry man. Hopefully someone else comes along.

What exactly are your Temps and what cooling solution are you using? 

[TSL]

If MCE is off it could be a voltage regulation issue. Possibly fixable in a firmware update. Are you running the latest bios for your board?

[Jurrunio]

It's typical for the mobo to send too much voltage. You need to undervolt it in this case. What software did you use to read the voltage?

[xg32]

start at manual vcore of 1.3 and work ur way down. use hwinfo for voltage/temp reads. Also check the other voltages like vccsa/io and see if they are at something like 1.3v, lower them if they are.

[Thauner]

Thank you for all the answers! 

 

I updated the bios last night, no difference there. Mce is still off. 

 

Can you or someone guide how to find vcore stage that works? I haven't messed with bios in that way before. Adaptive or what should be on off? Maybe some screenshot from someone who tried? Thanks

i dont have an asus board but im hoping ur bios look something like this

u can set ur vcore to 1.3v, VCCIO to 1.15 and VCCSA (system agent) to 1.15

 

after that if it's stable lower the vcore only til it's not stable (1.3->1.275->1,25 etc), then bump it back up 0.025v

So I could just copy these settings or is there any chance of doing any harm to my cpu or mobo?

There's no risk as long as you don't use a higher voltage.

at least for the cpu it should be fine, better than the 1.49 you are running right now, as for the vccio/vccsa, too low will cause instability, i keep seeing 1.1-1.25v (for overclockers) as the range.

 

I personally use 1.15 on a different board, no guarantee that's the same for u tho.

 

Edit: just a note, i've seen some1 on here with his auto voltages ALL at 1.4v, including VCCIO/SA, his VRM was like 120C, just making sure that's not the case here. Asus really needa fix their stock settings.

Okay, I guess I'll just have to try my way. But I will keep you updated with the results. Think it's bad that the cpu is so new that I can't find that much about it. 

 

Edit: will the balanced power mode in windows work with a manual voltage setting? I don't want my system running at the same high voltage all the time?

I think manual voltage MIGHT set it at a fixed voltage all the time, in order to ensure you have idle voltages/clock speeds you need to use offset voltages, thats another can of worm, ull need to find what fix voltage ur cpu runs stable at before moving onto that.

Crap. So I can't just use his numbers then? 

 

Anyone know for shure?

u can start with those numbers, and see what your idle voltages are at in windows, if u are unhappy with them then start using offset mode.

Yeah I'm gonna try them. 

Is adaptive same as offset mode?

I now tried different things, did it with Intel xtu because I didn't find a proper guide to fiddle with bios. Made an offset (adaptive). Worked my way up, when I get over - 0.075 its not stable. But under its fine. Tho it's making no or very small difference? My vcore is 1.329v and ViD 1459v. Anyone? 

 

BTW, is vid volt always higher than vcore?

i'm not an expert on that but i believe one is the voltage the mobo outputs and the other one is the voltage the cpu receives, mine is 1.39 vs 1.35, in ur case it's probably not stable because -.075 makes the voltage too low

I locked mine in at a cap of 1.3 volts, under full load I sit around 1.25 volts according to HWMonitor. Anything lower and I blue screen.

So your volt setting is constant? Or what mode did you set it as? I still want my system to idle, and may I ask are you on Asus mobo?

Makes sense what you're saying about mobo vs cpu volt. I took a look in bios under cpu voltage settings (didn't change anything) but it was set for 1.350v stock settings.

Late answer here, but got some news.

 

I have set all cores to sync at 4.3 and made an offset voltage with -0.075

My temps is lowered by 10-15c under all loads. And on full load i dont see it over 80c anymore (95-97 before). 

Also my vcore is now at its max hitting 1.285v.

 

Now, the only thing I worry about is the idle volt in windows. Its at 0.530 as the lowest ive seen.

Is that critical or is it just fine?

[b166ar]

My delided and undervolted 8700 none k with small Noctua l9i hits 69-72C max in blender benchmark or Prime 95 26,6.

Default VCore was 1.250V. but it's stable for me with 1.140V. 

 

1.489V and even 1.3V sounds crazy for me
