What do you guys reckon to be safe 24/7 voltage? Like I've said I just upgraded from a 8800GTX and voltage tweaking was not an option on that card. I know overclocking can hurt hardware and I know there is not an absolute answer to this question, but in general terms. Dont worry about temps either, winter is coming to Norway so I might be able to have some more fun in the coming months smile.gif

The ASUS GTX570 Direct CU II has the same vrm's as the gtx580 as opposed to the reference gtx570. Having those extra (2 xtra to be exact) we have a higher overclock potential with this card. So the max Ive seen and have been told is 1125 if you want to stay within reason. Just keep temps as low as you can tolerate the fans. The lower the temps the better. One thing to think about is attaching a fan to blow air on the vrm's, cause they tend to get hot.

Thanks. Seems like i need to get my soldering iron out then. I've got some fans here, but they are pretty noisy. Think I'll just solder a resistor in series with the fan to make them slower/quiter. 900 mhz almost seemed stable with 1.088 volt to the core. Gamed for a couple of minutes before it crashed. Need to use 1.1 volt to reach 900 mhz stable. With 1.1 volt i can probably up the frequency a little bit more since I could game for a couple of minutes.

wait im confused, your going to attempt to slow the fan speeds down by using a resistor? Use the supplied software or msi afterburner which is my favorite and set the fan speed there

Not the fans on the graphics card. The case fans I have laying around my apartment. The case fans are just to noisy for my liking.

930-940 at 1.1 is the norm that I have seen. 1.125 is good for 950.
soldering....Thats cool, Id just buy a low speed yate loon fan for like $2. biggrin.gif

If you manage 940 mhz at 1.1 volts then I'd guess you could do more than 950 at 1.125. 10 mhz seems a bit on the low side for a voltage bump of 25mV. But I guess frequency scaling will become increasingly worse when you push the card.

Edit: About the fans. I alredy have the soldering iron, the fans and resistors so I'll just mod them to run at a lower speed to save the money.

lol cool, yeah figured I would ask, sometimes you just dont know who is on the other end plus I read it while at work so that might have led to my misunderstanding

Hey i just wanted to know i there is any type of support bracket that you can get to keep the card from sagging?

You gotta make your own, as far as i know there isnt anything to buy since a lot depend on your case. Just a thought maybe a coat hanger with shrink tube on it would work nice, its easy to do sharp tight bends for bolts with a needle nose set of pliers. Its come in handy in other hobbies
