Gainward GTX 570 Golden Sample Goes Like Hell reviewed - 7. Overclocking, Power Consumption

Written by Sanjin Rados

Review: It really does go like hell

Overclocking


Without voltage changes and at AUTO fan settings, our overclocking resulted in 875MHz for the GPU. This is not a bad result all things considering but if you crave more, you’ll have to resort to upping the voltage. Gainward GTX 570 GS GLH allows for voltage changes via the Afterburner tool, which we used. The card runs at default 1000mV whereas upping it to 1150mV allowed us to push the GPU to 950MHz and the memory to 4200MHz (effectively).

Thermals

Idle temperatures were around 46°C whereas intensive operation resulted in about 77°C, which is pretty nice. Our overclocking raised GPU temerature up to 85°C.

Noise

The fans are not too loud but are louder than on the reference card. Although we expected a bit quieter operation in intensive GPU utilization scenarios, we were pretty happy with idle “noise” as the card was almost inaudible.

Although the fan tachometer doesn’t report RPM variations, our test card made a somewhat howling, high frequency noise. It is possible that this is a mechanical fan flaw and it could be an isolated case. Good thing about the cooler is that it keeps the card 8°C cooler than the reference card (77°C compared to reference cards’ 85°C).



Power consumption

Gainward GTX 570 GS GLH's higher consumption is partly due to the factory overclock and partly for different power regulation. If you recall, Nvidia made a consumption regulator which prevents the GTX 570 from exceeding predefined consumption.

It is indeed like a relabeled 480 .
With one disabled SM and a few disabled bits of data , and of course a new cooler .
But what's the point of throttling again ?

It really goes like hell, hehehe:

509W full load= more than the 580...nuclear plant needed (add to my shop list)

Gainward besides MSI is the best brand for nvidiots cards, but i sitck to AMD for life.

Happy nuking. :D

The performance does look good indeed. But right now I'm happy with my HD 6970 that I have just bought, so hopefully with new drivers the performance should increase over time.

Its more power hungry than 580. :o

What's teh point of throttling? Ask AMD, since you and it are best buddies. *cough Powertune cough*. ANd if you think the 570 is a rebadge, you are truly out of your league here.

My PNY 570s run at 0.95V for the stock 732Mhz. For 850Mhz I have to use 1V as well.

The power draw may be higher than the 580 but look at the bright side. You only OC when really needed and it is nice to know that you can have 580 like performance for 150 euros less.

This is the case for the 570 GLH really. 1V at 800Mhz=higher power draw than the 580.

That's why you get stock clocked 570s and you OC only when needed.

The exhaust inside the case is a fail btw. Reference HSF FTW!

Powertune can be changed / switched off in OverDrive .

I am sure you people have seen the news that a 6950 can be BIOS-flashed to enable all the shaders and bits and pieces - you get a 6970.

If you can do the flash (I still have a pair of 4890s, haven't tried it), then the dollar value seems to be the 6950 no?

Funny thing about the above is that AMD knows about burning gates - we used to overclock Athlons using pencil lead tracks between contacts on the top of that CPU that set the multiplier. I suspect the 6950 can be flashed to 6970 because AMD wants people in the know to do it instead of buying nVidia.

The unwashed masses will never know the difference - but they will probably be buying on bang for the buck not absolute performance.

What do you think of this?

I did the BIOS flash update to my HD6950 and made it a HD6970 basically, I posted a video with results here http://www.youtube.com/watch?v=UEZL5vezYm0
