GTX480 @ 850/1700 stock volts?!

post #1 of 12
Thread Starter 
Recently picked up this card off Craigslist and decided to do some testing along with replacing the TIM since idle/load temps seemed high.

So far I'm at 850/1700 at 1.038v

I just replaced the TIM with some AS Ceramique on the stock HSF and after five minutes of FurMark burn-in testing I was at 94*C

I haven't ran anything but FurMark as far as benching goes so I don't know if its stable with actual gaming.

Is this unheard of? Your thoughts are appreciated thumb.gif

I would back off on that overclock if you want to actually get a chance to use it much longer lol. 94 degrees is really pushing it, even for a GTX 480. As for the overclock, it seems pretty high for stock volts. Are you sure it is actually running at that speed? Check Gpu-z just to be sure. If you can get the heat down using a better paste (ceramique isn't the greatest), than you may have a "golden sample" 480.

I was under the assumption these cards can run up to 100*C without any trouble?

It maxed out at 96*C after the FurMark 15min burn-in benchmark, didn't notice any artifacts. GPU-Z and MSI Afterburner both report 850/1700

As long as your card is stable I would keep that overclock. 94 C is not that hot for the GTX 480 especially while running Furmark.
Just make sure you use a more aggressive fan profile than the Autofan. Because the Autofan will always leave the card at low 90s while gaming. and it is always better to be safe than sorry.
My GTX 470 will go to 100C+ while running Furmark. And I own this card from almost 2 years ago. It is still going strong. And I am deciding in keeping it until Kepler is released. I get a max of 85-86 C while gaming Crysis for several hours. So your card might not get that hot in real world games, and as from what you can see my GTX 470 is 15C+ cooler than the temp measured with Furmark.
The best stability testing methods & must be your first priority are real world intensive games & benchmarks like :
1- Crysis series (I use the Benchmark Tool and run 99 loops with it) if you card doesn't crash that means you are good to go. Also try to test this in the worst weather conditions to give you a better idea about your cards stability.
2- BF3
3- Skyrim

And benchmarks like
1- 3Dmark11
2- Unigine Heaven Benchmark. (More intensive that Crysis if you card is unstable it will either show artifacts or will crash in a matter of seconds.


And keep yourself away from Furmark. This program is meant to overload the voltage regulators to measure the highest power consumption from your card & the highest/ worst load conditions. Your card might not reach those loads AT ALL under any gaming condition. This is mostly used by reviewers to give the readers a general idea about the power consumption of a card. So it is almost useless to the end user and with prolonged runs you might kill the card with it, especially when overclocked.

You might want to dump ceramique grease. I've found out that it's not that good. MX-2 seems like I get ALOT better results with that. You might also want to consider doing my IHS mod. I had my card running fine for awhile then it just started getting hotter and hotter, my guess the glue for the IHS was wearing out and expanding and creating more space between the die and heatspreader.

I'd freak if my card got over 80C...

I've got some MX-2 in the mail that should arrive today. I'll swap it out and report back. I don't expect more than a couple degree difference. We'll see

It sounds to me it's a good clock using the stock VID of the card. thumb.gif

About the temps, i wouldn't be so scared, it's a synthetic test, it will always get higher then in real use. When all of my GTX480's had their fans at 100% and they still reached ~100C during gaming i started to get a little bit worried and swapped for watercooling. But when i ran one card i got to 90C all the time because of my quite fan profile.
post #8 of 12
both my cards will do 850/2100 @1.138V
they got to 85 on air with air con pointed in general direction
on water they don't get over 50
They are both on 70,00.21.00.02 Bios (Stock)

your Mem speed is a lot lower than I was able to get even when I was on air

Memory: 2050Mhz/4100Mhz Effective

Voltage: 1.07
Load Temp: 63c

So yeah, it's not unheard of smile.gif
