To push, or not to push

post #1 of 7
Thread Starter 
I have a EVGA GTX 460 768mb Superclocked edition and am potentially looking to Overclock it.

I have Precision, OC Scanner, and Eleet.

I have read the guides and know a good amount.

I do not really want to change voltages as that contains the most risk, thus why I am sticking with precision instead of Afterburner.

I just want to know if OCing an SC card minus voltage controls should be done, or if this card is enough how it is.

Also, if anybody has this card and has tweaked it already, please tell me your experience and current settings on it.

theres no risk in putting the core voltage up..if the temps are fine then you are completely 100% fine

First thing to consider: do you actually need it?

Secondly: Its not really very dangerous at all. I have never run into issues with it nor have I heard of anyone else having issues with it (gpu overclocking of course. cpu overclocking is a totally different issue..)

Terierialy... or whatever: Slowly push up your shader until it wont go any higher while staying stable.

If you feel comfortable with it, try pushing the voltage some. It will use more power, but wont really case any issues other than that as long as you watch the heat (dont let it go over 85c)

Cheers!

Well, EVGA Precision is a really nice app for OC'ing. If you can squueze a few more Mhz out of your card without touching the voltage then go for it. You will still see an increase in temps with OC without touching the voltage. Raising the voltage will definitely increase your temps more than not. I would reccomend that you pull the heatsink off your card and put some new TIM on it and OC away. Heat is what will kill your card faster than anything. So if you keep your temps in check and your card does not artifact after you OC, then all is well. Go for it!

I do not want to crank up my voltages because I do not want to raise the heat too much and from my knowledge voltage bumps give the greatest heat bumps.

The following chart was taken from an online review:


The OC numbers on the SC edition provided an extra 5fps bump to Crysis Warhead.

Do you think those numbers were achieved via the given EVGA Precision(no voltage tweaks), or with Afterburner(with voltage tweaks)?
Would you day those are good numbers? Rate scale of 5.

I also know that these cards say hey can take up to 110 temps, but we all know a card should not be that high. What is a safe, non-damaging temp to be at?

I want to know what to set my turn off temp restriction in OC scanner to avoid damage. 80?

Also, I know to raise shader and core clocks together, but when do I raise memory?

I've always found 80-85c as a max temp the best, anything over 82c they don't usually like too much, are are likely to see instability occur.

If you use that as your max, you can't go wrong. That and the 460's run cool, you should get a nice OC using 1.087v.

Voltage tweaking does translate to more heat, but in most cases you should be able to control that with the fan set at 80-90% when you get high temperatures.

From a reference card to the OCd Superclocked card there's a 11% memory clock increase and a 25% increase on the core clock. That's pretty darn good

I'm pretty sure the superclocked version of the 460 comes with an increased voltage. And therefore it overclocks better. In theory there's no difference between the two cards. Except the superclocked one is factory overclocked. Therefore I assume that they didn't increase the voltage on the two cards as they should get somewhat similar results - which they don't. Another thing that makes me think this, is that the temperature difference between the non-OCd card and the OCd card is only 2C.

I try to keep my temperatures below 85C. But as many will tell you, the cards can take much more. I'd probably aim to keep my card under 85C for everyday use, but I'm sure many would disagree

Generally you want to increase the core clock first, as that produces the most noticable increase in performance. After that you can increase the memory clock. But the core clock is most important.
