brianos007 Posted August 4, 2010 Share Posted August 4, 2010 Hello Guys. I was supriced how good the 480 gtx overclocks. I did a mild overclock at low voltage. The program i used as many do, is MSI Afterburner here you can download the latest version 1.6.1. http://downloads.guru3d.com/Afterburner-1.6.1-download-2562. Core voltage 1.100 Core clock 850 Schader clock 1700 Memory clock 1900 Fan speed auto. This is a mild overclock witch makes a hell of a difference if you run a benchmark You can go even faster witout any problems .Watch the temps I have a Antec 900 case with a 120mm fan blowing on the side of the card so no heat problems. Even on higher overclock speeds. Link to comment Share on other sites More sharing options...
Heiko Glatthorn Posted August 5, 2010 Share Posted August 5, 2010 Mild overclock ? lol Which stress test are you using ? Try Furmark fullscreen with some AA to see black smoke leaving the back of your case... Link to comment Share on other sites More sharing options...

Spirit Flyer_old Posted August 5, 2010 Share Posted August 5, 2010 Mild overclock ? lol Which stress test are you using ? Try Furmark fullscreen with some AA to see black smoke leaving the back of your case... LOL, The core clocks don't mind those numbers too much but the memory is pretty much maxed out already at stock. Bruce, a member of the Back Country prop Club has a 980X CPU and two water cooled 480 GTX's in SLI OCed to 950Mhz, and says they are perfectly stable! That is serious horsepower...

jnrjim67 Posted August 5, 2010 Share Posted August 5, 2010 Nice clocks brianos007 I have mine at 800/1600/2115 @1.1V tested and stable, and I did these settings straight off the bat. I also noticed the fan noise is good under FSX as it doesnt utilise the full potential of the card and does not get hot but if I try other games like ArmaII , Crysis or metro 2033 the fan becomes loud you see 100% GPU usage for the card in these types of games.

brianos007 Posted August 5, 2010 Author Share Posted August 5, 2010 Hi guys I see in your Sig(Heiki). you have almost the same settings on your 480 This is a mild overclock in my eyes. Dos 480s are overclockable with the right cooler you cant imagine. My Antec 900 have 8 vents at full power its stays really cool. A bit noisy i admit but when flying you wont notice Like Steven said a beast of a card wit a lot of potential The stress test i used was the one from MSi. I will try the one you mentioned but i dont see any problems If it blows and going up in vapor i let you guys now Grtz Link to comment Share on other sites More sharing options...
brianos007 Posted August 5, 2010 Author Share Posted August 5, 2010 Dos furmark work on a 64 bit system i went to there site and all the downloads are for the 32 bit op systems. Link to comment Share on other sites More sharing options...
Iain Emms Posted August 5, 2010 Share Posted August 5, 2010 just interested What would you chaps say is a safe overclock for a 480 though without blowing it up. cheers Iain Link to comment Share on other sites More sharing options...
HiFlyer Posted August 5, 2010 Share Posted August 5, 2010 Strange. While I will gladly overclock the heck out of my CPU, graphics card overclocks always make me nervous! It seems that too often the way you find out that you are too high is when the artifacting begins, and all to often, its too late after that and people wind up returning their cards for RMA while attempting to look innocent!

brianos007 Posted August 5, 2010 Author Share Posted August 5, 2010 Hi Ian. Have a try at my settings . No artifacts no exessive temps in FSX it stays around 50 °C. And 1.1volt is realy safe. Gtz Link to comment Share on other sites More sharing options...
jgruschow Posted August 5, 2010 Share Posted August 5, 2010 I too am running two 480's in SLI. Has been at these settings for the past couple of weeks. Running perfectly. Jack Link to comment Share on other sites More sharing options...
Heiko Glatthorn Posted August 6, 2010 Share Posted August 6, 2010 Dos furmark work on a 64 bit system i went to there site and all the downloads are for the 32 bit op systems. Yep, works for me with Win 7 64 bit. For me it's as far as it goes with default voltage. At < 60 C i have a huge headroom regarding temps but i won't increase the voltage - i am planning to keep it a while without degrading... The current performance is more than sufficient.

brianos007 Posted August 6, 2010 Author Share Posted August 6, 2010 Hi Heiko. I give it a try on my win 7 64 bit You are right wat you are saying about the 480 GTX (The current performance is more than sufficient.) I even think a 470 GTX is the best GPU to go with a I7 93O OC let's say At 4.2 ghz. A 480GTX will perform even better on the top of the I7 980 OC of course. This is my opinion but i think i will not be far of I have the bad habit of trying to overclock(It's a sort of a addiction) Grtz Link to comment Share on other sites More sharing options...
