If you leave you card at sligthly unstable OC,could it damage your card ?

post #1 of 8
Thread Starter 
Let's say you oc' you card and it's 99 % stable you can play almost all games without any problems,and then you find in only 1 or 2 games it would artifact sometimes.
I am talking about 1 artifact each 2 hours of playing,not artifacting all over the place.
And temps don't go over 65 C at full load,so it's not stable because of temps,but because of the core clock.
Or different scenario,all games work fine but it might give error or two in OCCT or similiar test.
Leave the card like that,would it mean there is higher chance of damage then leaving it 100 % stable.
I am not talking about slightly reduced lifespan,like instead of 10 years it will last 8 or something like that.
I am talking about more immediate damage,like in year or two ?
What do you guys think ?

youll be ok. Why not make it 100% stable? I couldnt stand having it OC and some games not working.

It would do no damage.

It shouldn't damage it. Only if it is becoming too hot. An unstable cpu on the other hand is much different. But still, an unstable gpu can cause many problems like BSOD, artifacts and game freezes and lags. So why not just go with a stable overclock.

I don't think so.

My understanding is that voltage and temperature are the damaging factors. You can put your core and mem sliders to max overclock and the card won't explode. However the difference between a slightly stable and a totally stable overclock is usually (in my experience) very small.

I'd just reduce my OC by 5% (or whatever it takes in your case to get stable) and leave it stable.

Even if they aren't killing the card, crashes can be a PITA, and for what, ~5 FPS?

I understand what you are saying,but I got odd example here where to make it run in those couple of odd games I need to increase a voltage a lot or lower a clock alot ( about 50 mhz )
And I am just generally interested in stable vs unstable core clock and safety.
For example,lower voltage slight unstable vs higher voltage ( and thus more heat ) 100 % stable - what is better for the card in the long run ?
Does stability play any role in damaging the card,or temp / voltage is more important ?

If its a ton of sustained crashes, BSODS, and artifacts because the core isn't getting enough voltage, then it will damage the video card.

If you only see one or two artifacts it won't damage the card.. It might shorten the lifespan by a little bit but nothing major.

Why don't you just shoot for 100% stability though? Crashes, artifacts, bsods, freezeups are all a huge PITA and are relatively easy to fix - just pass a 15 minute OCCT test with 0 errors.

Shoot for 100% stability on a higher voltage... You can setup a custom fan profile in MSI Afterburner that will offset any heat increases and will keep your card significantly cooler than the built in NVIDIA fan speed-steppings. I only hit 70C on my overclocked gpu and I'm on a reference design. If you keep your voltages and speed relatively reasonable no harm will be done.

Temp\\voltage are more important.

Like I said you can slide your clock to a completely unreasonable speed and the card won't explode, but doing so with the voltage can damage it. The same for heat. Even at stock voltage, if you let the card overheat, it is going to get damaged.
