Can't over clock on B450

[Guest]

For some reason I glanced quickly and thought of it as a drop down......

 

Doesnt the board have a different vcore option.?

 

I remember on Intel the dynamic vcore worked with speed step or something.

My apologies. 

Looked up some bios screen shots for this board.

That's just Intel's wording for v-core. Threw in Dynamic for no reason I guess.

 

Try and disable the C-states. See if that helps.

I'm curious why you decided on relying on voltage offset rather than setting your desired voltage, is it because your mobo doesn't let you just plug in a vcore and go? It does seem that under load you're still in relatively safe voltages and you do have room to push farther if that is desired. 1.4v, though not really recommended for 24/7 usage at that voltage, is certainly doable and if it means getting those extra clocks, if you think it's worthwhile then give it a shot.

 

I personally never reply on a motherboard's voltage offset to set any voltages - I prefer to just set it to what I want and fiddle with LLC if need be.

Like i said before! I CANT GO FURTHER that 3.9GHZ because i cant set more voltage. My base voltage is 1.0v. By adding +0.3v i am getting 1.3v and that is not enough for 4GHz!

so why are you using the offset if it's not giving you what you want? Override the voltage and shoot straight for 1.4 if you don't care about longevity and just want clocks  

Honestly even the 1.35v that most ppl tout is based on nebulous information imo. At least it isn't as bad as running 1.4+ 24/7.

 

If your motherboard doesn't let you override vcore it's time to consider a motherboard with an actually functional bios, or rely on ryzen master instead.

 

Out of curiosity what mobo is it anyway?

did you know that processors burn not because of voltage, but because of temperature?

It's usually the voltage that kills CPUs.

There is usually a temperature limit programmed into the CPU, and it will cause the system to shutdown, or thermal throttle the CPU frequency.

If you pump 1.5V+ Core Voltage into a Ryzen CPU, it will shorten the lifespan of the CPU, or cause it to straight up die.

 

Out of curiosity, if you revert your overclock to stock, and let the Core Voltage run on Auto, and stress the CPU, what do you get?

 

On another note, if the motherboard BIOS is only allowing you to add a +0.300V offset, you may need to do your overclocking through Ryzen Master, etc.

This still does not answer question on WHY the Core Voltage is so low.

 

Make sure you have the Ryzen Power Plan installed -- since it is now part of the chipset drivers, make sure you have the chipset drivers installed.

Ryzen 1000 and 2000-series still requires the custom power plan, while it is not "necessary" for Ryzen 3000-series.

 

I might have to dig into this, and actually get my hands on the actual Aorus B450 Elite board, and play around in the BIOS.

Three of my buddies built new Ryzen systems within the last ~5 months, and two of them are using Gigabyte B450 motherboards.

Just need to remember if it was the B450 Elite, or the Pro...

So the X model is better silicon.

Mine does 4.1ghz on 1.410v (auto v-core)

 

Depending on the temp, I can run it as low as 1.1880v at 4ghz. (have ss if you want)

These chips seem very responsive to cold temps. Reduces quite a bit of leakage for sure.

I just started digging online...and found THIS snippet of information.

It looks like you are limited the +0.300V on these Gigabyte B450 boards, as far as Core Voltage control DIRECTLY through the motherboard BIOS.

That is disappointing...

The overclocking capability within the UEFI for this particular motherboard is surprisingly constrained – there is no Load Line Calibration (LLC) or different voltage operation modes. In fact all that is available is a CPU VCore offset, up to +0.204v, and an SOC offset up to +0.300v. In testing this meant a voltage limit of 1.21v on the CPU VCore for the Ryzen 7 2700 which means a roughly overclocking limit of 3.7~3.9GHz, whereas most CPUs should be cable of 4~4.2GHz with more voltage, such as 1.375v. The overclocking capabilities are disappointing.

 

UPDATE 05/10/2018 – Gigabyte issued an updated UEFI version F3B which supports up to 1.3v vCore with the Ryzen 7 2700, by increasing the maximum offset from +0.204v to +0.300v. See more details on the page “Overclocking & Power Consumption”.

To test the Gigabyte B450 Aorus Pro motherboard’s CPU overclocking potential, we set the CPU core voltage no higher than 1.4V and push for the highest stable clock speed. We maintain the DRAM frequency at 3200MHz to take memory stability out of the overclocking equation. Once the highest clock speed for 1.4V is achieved we see if there is potential to reduce the voltage while maintaining system stability.

 

Overclocking with the Gigabyte B450 Aorus Pro was a distinct disappointment as the restrictions within the UEFI meant we weren’t able to increase the voltage higher than 1.2v. We’d normally push towards 1.4v to achieve the best possible clock speed – around 4.1GHz.

Gigabyte permits only a positive offset for the VCore voltage of +0.204v, given the base value is 1.0v the maximum final achievable voltage is about 1.2v. With a 1.2v limit we were only able to achieve 3.9GHz, 0.2GHz lower than normal. This restriction was present with both F1 and F2 revisions of the UEFI.

 

Based on other reviews of this motherboard present online, it seems that the same restriction is not present when using the Ryzen 7 2700X. However, when that CPU is used more voltage is possible, up to 1.4v, although the VRM does seem to get quite toasty in that scenario.

 

From our testing, even using a modest 1.2v on the vCore, the efficiency had already fallen to approximately 76 per cent (down from 92 per cent at stock) resulting in 25-watts of heat output. Therefore, under higher vCore voltages we’d expect the heat to increase and the efficiency to get worse, thus it’s easy to see where overheating issues could originate from when using a Ryzen 7 2700X.

 

So it looks like +0.00V offset is 1.00V, and caps out at around 1.300V.

You are limited 3.7 GHz ~ 3.9 GHz given the voltage limitation.

 

In your case, since 3.9 GHz is not stable, you are restricted to something under that.

Might need to consider a higher-end socket AM4 motherboard...

hey i made it through ryzen master. But you are saying that it shorting the lifespan. I compared 4.5GHz and 3.9GHz. Not a lot improovement. But temperature risez up to 80 Celsius vs 50 on 1.3v. 3.9 is pretty stable. I compared +0.25v and +0.3v. 250 is not stable at all. It bsod while cinebench. 0.300v is stable. I am getting 4th place under Threadripper. I guess ill just stick with 3.9GHz. Maybe in the future 4GHz

you want me to fry my cpu? Like i said before. It reaches 80° in idle. It throttles at 95. So no sorry. I can do 4.2GHz. I am afraid

[Guest]

This is the best mine does Bios to Windows overclock. 

 

4.3ghz all core is the max with stability.

4.1ghz good thermals at 1.410, can achieve with the stock heat sink.

 

4.5ghz is outstanding for you chip and 4.7ghz is unheard of without chilling.

What is the Core Voltage it is being actually applied?

Like I said, if baseline voltage is 1.35V, and you are adding +0.300V to it, that is already TOO MUCH.

 

If you are adding +0.250V at once, that is quite a bit -- you should be increasing the Core Voltage little by little.

Little as in +0.025V or +0.050V at a time.

 

Ryzen 2700 should be able to reach 4.0 GHz ~ 4.1 GHz with around 1.4xxV, or even with 1.3xxV in some cases.

4.2 GHz you are looking at something above 1.40V.

If you are pushing 1.5V+, and still only getting 3.9 GHz...

Agreed, I can hit 4GHz on my 1600 using live 1.35v

Right.... That screen shot was about 1.580v for reference. 

 

It's so hard to help you without visuals, but I gather the board is a POS for overclocking??

If you are IDLING at 80*C, then that is too high.

The CPU is programmed to throttle at 95*C, so it makes sense.

 

I wouldn't use 1.5V, but somewhere in the 1.4x V range would be fine for 4.0 GHz ~ 4.1 GHz.

If you can do 4.2 ~ 4.3 GHz using 1.40V ~ 1.45V, and the temperatures are in check, that would be okay.

Keep in mind the voltage required will vary from one CPU to another.

The ol' "Silicon Lottery" as they say.

I was able to hold a 4.8 GHz overclock with ~1.40V with my FX-8350 back in the day, while other some other users needed more voltage for just 4.6 ~ 4.7 GHz.

The AsRock B450M Pro4 seems to be so-so, doubled 3-phase VRM?  3(2) + 3 set-up.

According to VCore VRM rating tier lists/tables, the B450M Pro4 can support 100A Core Current.

Should be able to handle something like up to an overclocked 3800X / 3700X -- mild overclock probably, though.

Of course it still falls short compared to something like the MSi B450 Tomahawk / Mortar / etc.

POS meaning the bios, not the somewhat questionable VRM package. 

Allows only 1.30v, but capable of 100a, which I wouldn't lean on that too hard personally.

 

Then he's talking about 4.7ghz...... I dunno. Really doubt it though.
