is 1.3V safe for graphics card?

[MostWantedSoulRider]

I tried 1.3 V for 1200MHz graphics clock and 1500 MHz memory clock. The temperature reached 83 C. As the maximum fan speed is only up to 45 % for this overclock, can I stay with 1.3V?

Sounds a bit high to me, is it stable if you back it off?

Yeah, I agree that its high. Anyway, It is stable even for 1.28 V itself but when I stick around 1.3V, games work very smoother than before. Though the temp is 83, the fan runs only at 45% Max (FAN SPEED IS SET TO AUTO).
If the temp is bad for the card, then definitely the fan must be running like 70% to full. Shouldn't I stick with 1.3V even though temp is good as per the card?

I've done some more reading, it looks like 1.3 volts should be fine for that GPU. As long as there is no excessive heat or artifacting you're fine.

Thanks for the help, bro. I felt the same here as I was searching around the internet about the core voltage limit.

So, can I say something like this: "No matter what voltage the card is being set to and what temperature the card reaches during load, the fan shouldn't reach 100%" ?

Also, artifacts appear only if the voltage is not sufficient for the clocks. And, I made the above statement because it seems the temp is only factor to be considered after overclocking. Correct me If I'm wrong.

That's not necessarily true, for example my 7870LE reaches 100% fan speed to keep my temps below 75 as it is overclocked and overvolted quite heavily. Fan curves can be set by the user, however out of the box manufacturers usually trade-off heat rather than increasing fan noise for the benefit of consumers. However this may cause the GPU to throttle up and down as it heats up and then spins up to cool itself down briefly.

As for artifacting due to voltage as far as I know cards have a certain limit of how many volts can be applied before it will cause artifacting.

 

[MostWantedSoulRider]

Oh, okay. I never knew this. So, I'm safe with 1.3V?

Yep should be good.

 

[MostWantedSoulRider]

Thanks, bro. But I see your GPU is running at 100% fan speed. Won't they break?

And, I forgot a thing in here. The temp goes 83 C. Stress tested for an hour with Unigine Heaven. Do you have any comment on it?

Nope, the fan will be fine running at 100%. It depends what your personal preference is. The AMD 27x series is targeting 85 celcius for a sustained period of time so that temperature should be fine without significantly reducing the lifespan of the card. I just like to keep things cool. However I'd try to keep temperatures below 80, download MSI afterburner to create a custom fan curve to manually adjust the fan speed at each temperature.

83°C is a bit high but safe for a video card. Video card components are designed to handle temperatures nearing 100°C. Additionally, games should average a bit cooler than a stress test, because they won't generally be a constant full load.

The concern with running your fan at 100% is the noise. If the fan was likely to malfunction at 100%, then the manufacturer would not allow it to run that fast. They don't want to have to replace it under warranty.

Very very true. Thanks for the facts, bro.

the only thing is you don't know what your vrm/mosfet temps are. unless your card has sensors, or you have some thermal optics to see it, its just a guess. on average the vrm temps are about 5c higher than core. you really don't want them higher than 85c, this is why many agree on 80c as the max core temp. adjust your fan profile to what you consider to be tolerable and then overclock from there.

Hmm, Yeah. I made a post few hours ago, inquiring about VRM temps. It seems my card doesn't have a sensor to measure its temp. So, Can I run the fan always for 49% which keeps the temperature around 78-79C?

 

[nikoli707]

your fan speed isn't going to affect anything, you can run it at 100% all the time if you like but thats not realistic and it would be annoying. make a fan curve and as soon as it is above 75c put it at like 45%, as soon as it hits 80c, move it to 50%. otherwise when its lower than 70c let is be virtually silent, or whatever % level you consider quite while your not gaming. the card will move back down to under 40c when not it use, at least it should, and more likely around 28-35c depending on your case and ambient temps.

i keep my fan profiles at like 100% fan speed for like 90c if for some reason it ever gets that high due to a malfunction.

Thanks for the info. And can I overclock beyond 1.3V? I will make sure the temp doesn't surpass 78 C.

im going to presume that whatever the voltage limit msi afterburner(or whatever program your using for the overclock) tops out at is what amd still considers safe. and of course i mean on the stock bios of course, and using vanilla msi afterburner with no hacks. and again this is temperature dependent too.

depending on the card design, a custom bios and/or combined with some software hacks and msi ab hacks, you can overcome this out the box voltage limit. those who are water cooling will likely want a card that can go much farther on voltage so that the chip can achieve very high frequencies.

Stock bios? I didn't get it, bro. My card has dual BIOS. I've to set 2nd bios to adjust voltage. The stock BIOS never let me adjust vcore. And the max vcore I could see is 1.35V (Not extending official limits)

i mean a non factory or out the box bios. my classified 780 has a bios i flashed from skynet. it unlocks up to 1.5v(up from 1.212v) core, a 200%(up from 115%) power target, disables dynamic boost control, and a few other changes. almost all cards now are not able to do these things as they are to a certain extent hardware locked to limits that no software changes or bios can overcome.

unlocked cpus are this way. all unlocked intel/amd processors will totally allow you to plug in a ridiculous 1.5v(or higher) vcore and some outrageous core frequency multiplier. its obvious you can try, but it will completely fail, and possibly cause damage, unless you have a very special cooling system. basically they do not limit you to a vcore/core clocks that needs to be overcome with a software hack, you just need a motherboard that can control it. any modern gpu needs to be software hacked to completely remove limits, and some are completely hardware locked meaning cannot do it even if you wanted to.

Thank you so much. I'm learning a lot of new facts. In the meantime, I'm having a trouble. Hope you can help me out. The custom fan profile works only if I keep the afterburner open. When I close it, the fan speed profile goes to automatic, switching off the manual settings I've fed in. Hence, I'm keeping the fan at constant speed of about 75%.

Thats normal, just minimise afterburner. It won't have an impact on gaming performance at all.

 

[nikoli707]

afterburner should just minimize to he system tray. you can set afterburner to load on system start and apply the overclock automatically, along with whatever custom fan profile you have made.
