NVIDIA GTX 970 OWNERS THREAD

Yes, i know what people using afterburner, but i scarry to burn my cards) once i try it was a bad experience for me)))

Maybe you should just leave them stock, it's pretty simple:

With afterburner installed and no settings messed with it won't allow you to increase voltage anyway, so less likely to burn your card, not that +87mv would do that anyway as it seems it only really adds +32mv.

For a starting point try 110% power, +100 on the core and memory at +500mhz, most Samsung ram on these cards seems to be able to handle it fine.

Put the fan to 100% and run a benchmark such as firestrike or heaven. You can leave the fan at auto if you want, I just always max it for benchmarking.

If it works increase the core in 20mhz stages until it crashes or artifacts. Then lower it to the previous value that worked.

Do all this and then if you want extra from overvolting ask how to do that.

Just received my MSI 970, tucked it in and opened up Afterburner. I'm not able to add voltage, although its ticket in settings. Anyone care to enlighten me?

Settings > tick Unlock voltage control

Restart afterburner

 

[Ayahuasca]

I'm worried now, I just whacked 200MHz onto the core (did 100/125/150/175 first) but didn't touch power %, should I?

If it works then it doesn't matter, I just do it so the card is less likely to hit the power limit.

That's what i did. Still not able to do anything

Will reinstall it i guess

Did you install/reinstall drivers after installing the card?

What's other peoples MSI 970 Gaming voltage hit when at +87mv?

I tried +37mv on mine and gpuz read 1.25v up from 1.20v, then I tried +87mv and was still 1.25v?

That's the issue, +87mv doesn't actually add that, it seems the card is BIOS limited to 1.25v. That's why between stock voltage and +87mv I can only add around an extra 80-90mhz, with +87mv properly applied I'd be able to break past 1600 I think.

 

[Ayahuasca]

Also can the 970 be flashed/unlocked to 980?

Doubt it can be unlocked to a 980. Different PCB I think.

Custom bios or Afterburner hacks should become available to unlock extra voltage and power target though.

Mine is 1.218v at stock, someone had a look in the voltage table in the bios and I think 1.32 is the max we'll see when unlocked bios appear.

 

[Ayahuasca]

The voltage slider in AB only goes up to 37mv for me if that means anything.

You bought reference style cards didn't you? That's all those will allow, the MSI, Giga and other overclocked models allow +87 but obviously it doesn't do anything extra due to voltage being limited to 1.25v.

 

[Ayahuasca]

Got mine at 1416Mhz Core Clock and 4000Mhz Memory, temps max at 61C and can't even here the fans

Played 64 man BF4 on the Pearl Market map:

GTX680 (Overclocked)

Frames Time (ms) Min Max Avg
127225 1608359 40 120 79.102

GTX970 (Overclocked)

Frames Time (ms) Min Max Avg
96350 1168094 46 128 82.485

Not really impressed with just a 3fps increase on average tbh. Maybe it's because BF4 is more CPU dependant.

64 player servers rely more on your CPU.

 

[Ayahuasca]

I won't keep it 3 years either but it's always nice to be able to sell it on with warranty still available.

 

[Ayahuasca]

As per my previous post earlier today about the 1.25v voltage limit I've been playing about. If I had +87mv the card will show 1.25v. I've just tried adding +40mv and GPU-Z is showing 1.262v. What the hell is going on lol.

 

[Ayahuasca]

Yeah it seems to jump up in stages, mine seems to be 1.218v at stock, then 1.243, then 1.262.

1.243 seems stable though when I check the graph in GPU-Z where as when it's at 1.262 it seems to jump up and down between 1.218, 1.243 and 1.262.

Earlier today it was showing 1.25v when I had +87mv added. Really not sure what's going on.

Games will work for hours then I'll go on a different game and I'll go back to a game later that was working fine and I'll get a D3D crash. Wonder if the memory is actually stable at 2000mhz for long periods. Someone said there's RAM chips on the back of the card that get really hot.

 

[Ayahuasca]

Going to leave it at +20mv, 1500/2000 and see if I get any crashes, if I do I'll put memory to stock and try again.

 

[Ayahuasca]

3yr warranty on that Zotac as well.

 

[Ayahuasca]

The Inno3D GeForce GTX 970 "iChill Herculez looks to be a monster.

Can see that being loud with the small fan on the side, also the 2 side fans on the front will be pushing air through those small vents in the fan shroud.

 

[Ayahuasca]

I've turned my 230mm Bitfenix side fan round and raised it higher so it blows air over the back of my 970, should help cool the RAM chips.

 

[Ayahuasca]

Mine isn't sagging Wizzfizz, there's a small bracket on the side of the card that seems to reinforce it a bit.

4pm

 

[Ayahuasca]

Nah they can afford heating

 

[Ayahuasca]

Finally fired up the BF4 campaign in 4K. It's beautiful! Runs perfectly on Ultra with my SLI 970s.

Not bad for "mid range" cards eh.

Enjoy!

 

[Ayahuasca]

That's a brilliant core speed for stock volts, looks like you've got a really good chip and that ASIC % actually means something.

 

[Ayahuasca]

IMO ASIC is everything. Ive owned a lot of GPU's and high ASIC have always been good and low have been not so.

Same experience here, 780 was 67% and would barely overclock.

 

[Ayahuasca]

Increasing voltage in afterburner really don't seem to affect the overclock on these cards, think we'll need custom bios. My max clock speed doesn't change between using +20mv and +87mv.
