Point of View / TGT GTX 580 Ultra Charged tested - 5 . Overclocking

Review: Factory overclocked to 841MHz

 

Overclocking, Consumption and Thermals

Geforce GTX 580 packs plenty of OC potential, with many partners jumping on the OC ship. While the reference GTX 480 runs at 772MHz for the GPU and 1002MHz for the memory, our factory overclocked Point of View / TGT GTX 580 Ultra Charged runs at 841MHz for the GPU and 1026MHz for the memory.

The memory on GTX 580 Ultra Charged has only received a minor boost but the GPU runs 69MHz faster than reference. This will be enough for about 7% better gaming results, but it must be said that there’s additional room for overclocking. In fact, our further overclocking resulted in 14% better performance when compared to the reference card.

Overclocking GTX 580 cards will depend on core voltage and overclocking results will vary from card to card. TGT team leaves room for additional overclocking on all its cards, and the good thing about PoV/TGT OC cards is that GPU voltage has been increased by default, which will help with overclocking results.

We recently tested a reference GTX 580 (1025mV default voltage) and managed to overclock the GPU to 855MHz. This is only 14MHz higher than GTX 580 Ultra Charged’s clock, but we didn’t mess with voltages or change the fan speed from AUTO mode.

Point of View / TGT pushed the default voltage to 1125mV, resulting in increased stability at higher clocks. Without meddling with voltages or changing the fan speed from AUTO mode we managed to push our today’s test subject’s GPU to 888MHz and the memory to 1150MHz (4600MHz effectively). Upping the voltage to 1138mV didn’t result in additional overclocking.

Higher factory clocks at the same time mean that the card will consume more compared to the reference card.

FurMark test is not quite favored by Nvidia’s driver and you’ll have to manually disable throttling or else the card will downclock on its own. Our consumption measurements show about 55W higher consumption compared to the reference card. The following results were recorded after we disabled Nvidia’s throttling mechanism.

During Aliens vs Predator test our rig consumed about 425W with the reference GTX 580 and about 473W with GTX 580 UC. Strangely enough, the same scenario with GTX 480 resulted in only 410W, which doesn’t quite concur with the GTX 580’s touted lower consumption. Nevertheless, we decided to publish the results as they were.

The fan isn’t too loud during intensive gaming and we can finally say that we’re pleased with the noise levels. Speeding up the fan didn’t contribute to overclocking headroom.

Nice to know that GTX 580 packs a decent overclocking potential. TGT's factory overclock is also impressive considering typical 10-20 Mhz range for most partners.

No Prince of Persia this time?

Awww!

These are nice, but where can we get one in the US? We are stuck with EVGA superclock and thats only 797MHz for the stock cooler.

I'm sure MSI will have a lightning card to try and top it but thats a ways off.

pretty sure you can get them through some online retailers or something

The performance is impress.. but need see HD6970 first..... :lol:

Power consumption???????

€525 = 694.915 USD = 2,192.57 MYR :-?
with these price,.. i can get 3xHD6870..

They should have included 6870 crossfire which is 10% faster than 5970 using the same power. 6870 crossfire is as fast as an 580 overclocked in most cases but costing 150$ less - 200$.

Having said that, it might be wise to wait until the second half of December when Radeon 6900 series hits the shelves, if for nothing else then for the price adjustments.

Or you can wait because 6970 might be 10-15% faster than 580 for 400$. (These are the current rumors, seems we will know for sure next week.)

Temperatures ? Very interested in that .
I'm Definite the 5970 is cooler at even a lower fan speed . Because the 5970 is damn quiet for its temperature .
