Can overclocking core/memory on a gpu damage it?

[Gryphhz]

or only voltage and temp? say a average increment on a gpu from core 980->1157 ?

If you go to high with the Overclock possible damage can occur, maybe not right off the bat but theres usually signs if the Overclock isnt stable.

As for how high you can go with said GPU, itd prolly be best to search for Overclock guides for your GPU to see what review sites n such have gotten for that specific GPU then you can go from there.

I did the increment on a gtx 670 and crashed so I lowered until stable but the question is can these crashes cause harm to a GPU? im paranoid like this lol

driver not responding was the specific crash then it restored.

Increasing the voltage on a video card or CPU can destroy them. Temperatures can also have a negative impact, but they can usually protect themselves from that.

interesting what about core clock/memory it protects itself also?

[Joscco]

I have my CPU overclocked from 3.3GHZ to 4.2GHZ but I didn't touch the voltage so I'm sure it could cause damage if it was too much. I also don't mess with the voltage when I overclock my GPU's.

The Display Driver crashing is pretty much how the GPU protects itself. when the driver crashes it drops all clocks to idle to prevent problems.
Core and Memory is the same thing as thats all you can overclock on 600 series GPUs, so yes thats included in that since thats all you can overclock. as i said, if you go to high it'll let you know.

Your powersupply will also limit how high of an overclock you can go.

Any overclocking will shorten the life of a component.

First rule of overclocking, don't overclock unless you can afford to replace the component and/or system.

No it does not protect it's self.

The Motherboard may shut everything down if the CPU/GPU/CASE temps get to high. As far as I am aware there is no temerature given for RAM.

Anything you overclock has no protection from burning out or frying. There is no safety for those features.

Yes, you can fry your hardware permanantly. While newer cards have safety mechanisms to reduce the risk, those safety mechanisms can and DO FAIL

Your best bet is to make sure you have something to monitor heat, and overclock a little at a time until you find what your chip is capable of.

There are two issues you run into on video cards: Heat and transistor response time. Both of these will result in data corruption and visual artifacts, so the only way to tell them apart is if the chip is too hot. Transistor response time can be improved by increasing chip voltage, but this has the nasty side effect of increasing temprature.

You can use a benchmark or some other stress-test utility to induce stress on the card until the heat stablizes to determine the heat being produced, and if it is functioning properly.

AMD ships a stress utility with their drivers, however it's documentation is very minimal, at least for the Linux version (atiode). I'm not sure if the Windows version includes better instructions or a GUI interface. What is nice about the AMD utilities is they will report if the safety mechanisms kick in, as well as if you get general errors. I am not sure if they report overheat, but you would do better using a separate utility for that anyways, so you can get a nice chart of temprature during the test.

On some cards you may be able to adjust the RAM timings. Slowing down the ram timings can allow you to increase the bus speed. This, however, results in the RAM going the same speed or possibly slower. This is useful, however, if the core speed and ram speed are required to be the same.

the motherboard shuts down to prevent damage?

So conclusion is only overclocking voltage and temp can damage a gpu? due to temp?

or temp in general.

[BlearyNeptune5]

If you have a GTX 670 why overclock it anyway?

you do it in baby steps, u increase the core clock up by little and little and little till it does not work, then u bring it down like 5 littles and try a burn in "littles being like 1-5mhz or 0.01-0.1 volts", watch the temps and the burn in images for errors, usally ghrey blocks / green lines etc... if temps dont go high or bad image errors its good, then to go higher even more, increase the voltage a small bit and repeate.

if u just go like insane vallues with voltage and core clock u could seriously dmg your card before the mobo shuts it off or ur computer just crashes.. if ur pc does crash or hang though during a burn in or new setting change unplug ur pc or hit the psu switch asap. also ati cards seem to oc allot more than nvidia, if u have a nvidia card dont expect to oc it much more than how it came ... probly not even worth it less u have water cooling " if its a nvidia card "..

even with stable clocks though and less than 80c temps, u can blow out stuff related to the vddc/power intake capicitors, if u oc with +voltage...

most cards are ok around 85c max... i personally dont like to see them over 70c.

you overclock you CPU or GPU to obtain a free performance boost :)

I run my Intel 2600K at at least 4.4 GHZ and my GTX 670 FTW at an insane overclock :)

to the OP check out this :

http://www.overclock.net/t/1265110/the-gtx-670-overclocking-master-guide


now all GPU's are not the same, but if you have a "standard" card then with no difficulty at all you should be able to overclock it the the level of the next card - so if its a standard card to the overclocked card level

The overclock on your 670 is done differently than of old its easy but you need to understand the procces and it effects :)

Please read the link a couple of times,before you attempt any overclocking if its a bit much then read only these two sections fully :)

•The Quick Method
•Setting up a Quiet and/or Efficient Fan Curve


but a basis of a simple overclock would be to:

install •Unigine 'Heaven' DX11 Benchmark run it to get a reading at stock
download and install •Precision-X - instructions are in the link

then change the power target to max - knock up the fan spped to 80% ( just to start off)

then re-run •Unigine 'Heaven' DX11 Benchmark and see whats the improvement is :)

Thanks for the info, now about the power target my card cant use more than 32% on heaven maxed is this normal, other software/games also.

I looked at others cards and they draw 110%+

[Daddio]

Yuo need to read the link, its not that simple, the power target is only the start of the process, for example I'm running @

Power target 145

GPU ofset +70

Memroy offset +156

this allows me to be overclocked to:

GPU 1280

Memory 3260

This is fully stable but my card is a EVGA FTW 2GB and as I mention before all cards are not the same, so Don't just drop these settings into yous :)

Thanks, but why does my card only draw 32% lol normal for a stock card?

I'll have a good read of that link also.
