BIOS/Hardware voltage lock is preventing GTX 1070 from reaching 1080 Performance:

post #1 of 64
Thread Starter 
Hypothesis - ALL GTX 1070's are either BIOS or Hardware voltage locked to not go beyond 1.0930v; as a result CORE clocks are limited regardless of whether you're on water or air cooling within a certain region (between 2000MHz and 2150MHz in most cases), preventing those with any GTX 1070 to achieve results similar to a non-overclocked GTX 1080.

My argument is that most of our cards can actually overclock higher on the core, especially with most of our SAFE temperatures. My damn card barely ever goes beyond 64 degrees celsius (using a custom fan curve); and I am using the stock MSI Gaming X cooler. Others on air-cooling don't even reach 40 degrees celsius at peak performance.

Our cards are stronger than what they are advertised to be, we are being held back by nVidia, who has told all manufacturers to lock their vCore at a maximum of 1.0930v (that's the highest I have found so far).

I am interested in seeing if the GTX 1070 Gaming Z is just a gaming X running at 1.0930v when at peak performance and not downscaling itself. Because I have noticed, over time running benchmarks, the core voltage decreasing automatically from the max of 1.0930v towards 1.0810v and remaining there, taking down my clock speed with it from 2088MHz to 2050MHz and remaining there...

Using MSI AfterBurner, setting the Core Voltage percentage to 0% sees it decreasing over time even further, taking the core speed down with it.

Trust me, I tested, it's not temperature that is preventing us from overclocking! It's the voltage. I went crazy and locked the FAN speed to 0% (which I done accidentally at first) and saw temperatures rising between 89 and 91 degrees celsius over a certain period of time without the card throttling and without the drivers crashing or artifacts showing up.

It's the voltage preventing us from overclocking.

This would make sense....if the 1080 wasn't capping itself at 1.093v as well...

It makes perfect sense.

The GTX 1080 has 2560 CUDA Cores & GDDR5X
The GTX 1070 has 1920 CUDA Cores & GDDR5

That's why there's a difference in performance, otherwise they use the same capped chip.

That's even more evidence that these GPU's are being capped by voltage & it's nVidia that has told ALL production companies that the MAX vCore allowed is 1.0930v

If someone manages to unlock the voltages on the MSI GTX 1080 & 1070 Gaming X's & Z's we'll know for sure. Since power draw won't be a limiting factor at all with their boards.

Aren't ppl sharing the strixOC bios with 1.24V already?

Heard it mentioned once in the 1070 thread in the last few pages. Which is where I spend my time on this forum. No one has actually posted a 1070 unlocked voltage BIOS, nor has anyone in that thread confirmed it works or anything yet with regards to the MSI GTX 1070 Gaming X.

I'm looking forward to it thumb.gif

Well, needing a custom BIOS to properly overclock NVIDIA cards is nothing new, is it?

That's bad business. You shouldn't sit there and defend it with that tone you're using as a consumer. Unless you're not a consumer and represent a company, than I can see why you might be frustrated that we're trying to get to the bottom of this issue. And yes, it is an issue.

nVidia make the specs for their products, not the customers.
Getting all flustered over it seems pointless to me. It's been like this since that 590 blew up.

If voltages were unlocked, the headlines would be "Nvidia GPU's suffering SUDDEN DEATH! due to excess voltage". It wouldn't be "Stupid consumers apply too much voltage to their GPU's causing sudden death". Nvidia would still be the one that takes the blame.

If you really want extra voltage, flash your GPU with an unlocked bios (when available). This "backway" helps filter out people that don't know what they're doing.

I don't think it's voltage, power limit, or binning, but rather a combination of all three. FE is clocking furtherst by a long shot for me, but voltage isn't helping scaling.

FE @ +0mv and 100% power limit = maximum boost ~2100 MHz with occasional dips to ~2075 MHz
FE @ +0mv and 112% power limit = maximum boost ~2164 MHz and occasional dips to ~2150 MHz
FE @ +100mv and 112% power limit = maximum boost ~2164 MHz and frequent dips to ~2100 MHz
Non FE @ +0mv and 100% power limit = maximum boost ~2025 MHz with occasional dips to ~2000 MHz
Non FE @ +0mv and 126% power limit = maximum boost ~2050 MHz with occasional dips to ~2000 MHz
Non FE @ +100mv and 126% power limit = maximum boost ~2075 MHz and occasional dips to ~2050 MHz

The best speed I've had was with voltage set to +0mv on a FE.
