The one aspect which piqued everyone’s attention at launch was the GTX 580’s willingness to overclock. Unlike past flagship products that are already running at or near their allowable limits, NVIDIA seems to have built in a good amount of headroom into their latest and greatest.
After using a trio of GTX 580 cards for the last two weeks, we can honestly say that NVIDIA has released an overclocker-friendly card. Every one of our samples reaches between 875 and 902Mhz without any additional voltage or changes to the default fan speed profile. Memory overclocks also ranged from 1080 to 1150Mhz which is an excellent improvement over the stock 1000Mhz speed.
Using the included SmartDoctor utility, the ASUS GTX 580 nailed 888Mhz core speed without so much as an issue but going above that required a bump in voltage. Its memory meanwhile reached a respectable 1097Mhz or 4388Mhz QDR before the GDDR5’s error correction routines we mentioned in a past article kicked in and performance couldn’t be increased any more.
By pumping the voltage to a moderate 1.138V we were able to push the core to 951Mhz which is a massive 179Mhz over the reference clock speeds. This was attained with a constant fan speed of 67% which is still quiet enough to not be noticed above the din of gaming.
We could have gone higher but we found this core clock / voltage combination offered a good balance of performance output, stability and fan speed. The clock speeds you see above are what will be used for the benchmarks.
We’re reasonably sure that with some time, effort, proper fan speeds and a bucket full of patience, most buyers of GTX 580 cards will be able to reach the levels we did in this article. These new NVIDIA cards are overclocking monsters and some phenomenal numbers can be squeezed out of them without resorting to over the top cooling methods.
To say that we were impressed with the direction NVIDIA took with the GTX 580 would be an understatement of epic proportions. In our opinion it can be considered one of the best cards released in 2010.
In its stock form the GTX 580 is already a hugely powerful video card but when you add overclocking to the equation, the results are simply mind blowing. The performance increases we achieved led to significant framerate gains across every single game and in some situations pushed playability to new heights.
There has been quite a bit of fuss made about NVIDIA’s implementation of current draw protection on their GTX 580 cards. It is supposed to limit the amount of power the GF110 core can consume but it really does seem to be a non-issue here - even when pushing the card above and beyond its reference clocks. From our experience, the casual overclockers among us who stick to air cooling will likely run into a heat wall long before NVIDIA’s supposed limiter kicks in. Once pushed to extremes, there may very well be a time when the protection routines scream “enough is enough” but even at 951Mhz, we didn’t see any type of limitation whatsoever. For the time being though, we have yet to come up with any evidence to suggest throttling will kick in when using any application outside of FurMark or OCCT’s GPU stress tool.
Bicu da sam tajLepi rezultati u oba slucaja ! Ali gtx 580 je single cip sto ostavlja prostor za najmanje jos jedan gtx 580. Ko ima x58 plocu, adekvatno napajanje i 900e![]()
Jedva cekam da vidim sta ce da urade sa dualkom? U svakom slucaju bice sporija od 2x580 gtx . Tako da komotno moze da se uzme 2x asus gtx580![]()
Pa sad najbolje da kosta 800e?Nema sanse mora biti jeftinija.![]()

Boga mi ova verzija brije sve redom:smash:
Malo mi velika def. voltaza od 1.25V, mada mu to daje prostora za dobar OC.
