Why is my 480 showing like this in GPU-Z?
- Thread starter Flare
- Start date
Nice overclock
.
I think you'd be playing Metro and Crysis very well with a core clock like that with 16xAA.
Why thank you
I'm still in the process of OCing, i doubt i will be able to get the core higher then about 840MHz, when i'm done with that i'll up the memory. I am still using stock voltages because i don't know what upping the voltage achieves The Crysis demo looks awesome, i need to buy some more demanding games though!

lol
.I'm not sure in the overclocking capabilities of the GTX 480 as it seems to be pretty varied. Good luck
.As for voltage, well just say you overclock to 840Mhz as you've said and everything is stable, no crashes/artifacts, then if you put the core to 850Mhz but now the PC was unstable then that is the max clock you will get at that voltage. To reach 850Mhz stable you would need to add a little voltage and then run the game/benchmark that caused the instability before and if it passes in the various tests you put it through where it failed before, then it would seem to be stable. So then you'd try 860Mhz and higher until you reached the wall again, then you would have to raise the voltage to gain stability again. Every time you raise the clock speed and voltage is when you should raise the fan if things are getting a little hot.
When you achieve the clock you desire and set the fan speed accordingly then you now have gained free performance. It's easy to do but can be time consuming if you're testing benchmarks and even though gaming is a better way to test it, it can be irritating if an instability shows and then having to stabilize again. Once you're set though then you don't really have to mess around again. The only time something changes is if there is a dust build up in the air cooler. Apart from that, it's usually plain sailing
. I think it's worth it IMO.Yeah, Crysis is still a great looking game
.Thanks a lot for that
I did think that was the case but i wasn't sure. I'm not really tring to reach a specific clock, i'm just taking it as high as i can. I'm a bit wary when it comes to upping the voltage though, do i have anything to worry about if i don't go to extremes?

We all help each other here
.I'm not sure on the GTX 480 voltage, Ravenxxx, Locky and a lot of others here at OCUK should be able to tell you that. If nobody replies though you could just Google "Max safe temps GTX 480".
If using Afterbruner to overclock then the max voltage it allows is 1.138v. I think that is within what some consider safe for air. Don't take my word for that though, wait for a combination of what you read through the links below as well as responses in this thread. I know little about the voltage levels with the GTX480 and this was just doing a little skimming on the search links below.
Max temperatures are 105C but the graphics card would just drop the performance of the card until it's cool enough then give you back the full power (safety measures of the design). I wouldn't want to run my card at 100'C all the time though but that's just IMO.
When applying your clock, keep an eye on the temperatures and adjust the fan speed accordingly.
Hopefully some GTX 480 users can come along and give you some pointers.

Thanks a lot for that info I think i will just leave voltages for now and just concentrate on the OC i can get at the factory voltages. I've set up a user defined fan speeds:
Up to 49C the fan is at 34%
up to 70C the fan steadily rises to 50%
up to 90C the fan goes up to 90%

Should be able to hit 850MHz easy on 1.1v, beyond that it varies from card to card - 1.1v is a perfectly safe voltage for 24x7 but it is the upper end of what nVidia rate the GF100 cores for.
That said so far I'm not aware of anyone managing to kill their 400 series cards from extra voltage and I know 1-2 who are pushing 1.2v through them for every day use. (Not something I would reccomend on stock cooling or unless you were prepared to replace the card tho).

I know! I've now dropped the idle fan speed to 30%, it's now idling at 41C.
Do i have a golden 480?
My 480 idle's at 35c-41c as well at fan speed 30%.
Well happy with it so far!
