7850 oced vs 660 oced

If it can kill your card it is detrimental. The only difference is that a big whack will kill it much sooner.

Overclocking is not detrimental unless you add silly volts which the card cannot handle. Are you suggesting overclocking a CPU is detrimental? Because it isnt, Intel have already expressed that your fine to overclock provided you don't put silly volts through it.

Please define "silly volts" for a 7850 and a reference.

Take a look here then:

Theres also quite a lot of threads along the same line. 1.25 is generally considered a safe max.

It shows lol

That is for cards with a non-reference cooler from the looks of it.

Exactly

You mean non reference PCB? The cooler wont change the volts it can handle :rolleyes:

Are you sure? If you wc the same card what will happen with the volts it can handle?

Bacon? · 20 Feb 2013 at 15:21

So now your going back on your own statement. Fantastic sense of normality you have here.

Isn't this what you wrote?

Bacon? · 20 Feb 2013 at 15:29

Yes because the cooler wont change how many volts the PCB can handle just how quickly (airflow dependant) it can get rid of the excess heat.

You only just suggested overclocking is detrimental to a GPU but are now saying its fine under water...

You are contradicting yourself here. Aren't you saying that heat will determine in a degree how many volts you can feed the PCB?

CyberCrow · 20 Feb 2013 at 15:38

Lmao but this is some cracking reading for a Wednesday afternoon lol

mranderson · 20 Feb 2013 at 15:41

Having a laugh too

Let's see what other members think about this. It is an oc'ers forum isn't it

Im sorry but just read the above you posted... And your saying im contradicting myself? *insert planet sized facepalm here*

If you push too many volts through a PCB which can't handle it then you have issues with raising the volts too high. The heat is a side effect of having high volts and thus you need a good airflow / cooler to get rid of the heat.

Having low volts means fairly low temps, and you dont need high volts to get a 7850 to increase stock speeds by 30%.

mranderson · 20 Feb 2013 at 15:51

Ok lets make it simple for you.
If the fan of your card fails will you run into any problems or not? Remember you are still using default volts - no increases, nothing.

Bacon? · 20 Feb 2013 at 16:06

If your running at load then ofc because the heat will build up within the PCB. That has nothing to do with voltage though. So at this point I dont know where your arguement is going :confused:

mranderson · 20 Feb 2013 at 16:10

Doesn't the voltage have anything to do with the heat????
