Moving towards overclocking, we’ve seen may times before that Gigabyte give their cards a reasonable overclock over reference speeds, and this not only gives a good boost in performance, but it’s also close to where the core’s top speed is. To aid with overclocking, the cards power target is raised as far as it will go (an additional 20%). Raising the core clock up, the card tops out at 1210MHz, boosting at 1262MHz, however when moving over to the memory overclock, the core needed to be lowered in order to keep the card stable.
Drooping the core clock back to 1200MHz (1252MHz boost) allowed the memory to flow free and after a lot of tweaking, the memory came so close to hitting 2000Mhz, however it just wasn’t to be this time. Overclocking to 1993MHz however is very impressive, working out as a 14% gain.
With a core overclock of just over 5% and a memory overclock of 14%, the WindForce 770 sees a performance gain of just over 6%, which is a nice addition although we do have to remember that this is already an overclocked card and performance will already be up from a reference GTX 770.
The Windforce cooler, although effective, is the ugliest cooling solution ever conceived, It’s a real eyesore IMO. Yuck.
I totally second this. There are many better looking dual-fan coolers from Asus, MSI..
Gigabyte should learn from them.
It’s really a good cooler (although it’s ghastly). If you ever buy a Gigabyte card with that cooler all you have to do is yank it off, get rid of that over applied glop the manufacturer calls thermal grease, replace it with a good quality paste (applied properly of course) and you’ll see the temps plummet even further.
Well, that’s bad.
P.S. I never used Gigabyte cards..
I don’t see what all the fuss is about. They’ve cleaned up the blue PCB and other than that its just a rather standard looking triple fan black VGA cooler
It’s just personal taste. I actually use a Gigabyte GFX card with the Windforce cooler but I can’t see it so it doesn’t bother me but I have no complaints about it’s cooling prowess. Although the colour of the PCB is important to some people, somebody pointed out to me that that it was no longer blue but black, I hadn’t even noticed. Working with these things all day long for a number of years, one tends to become jaded & cynical. I think it’s time for a break.
Except for the ugly outlook, it is good if not great in terms of performance.
GTX770 is itself a very good chip though.
Having a window in your PC is so 2001, who cares what it looks like? You only see the top of the PCB anyway, all that matters is how good it cools.
I actually liked Gigabyte’s cooler design and PCB color enough to buy two of them…670 style…but to each their own I guess.
Can’t let these vain naysayers convince people not to get the card just from its looks.
