ASUS Announces First Overclocked Radeon HD 4770 Accelerator

Barely 24 hours into the launch of the Radeon HD 4770, ASUS has announced its factory-overclocked, and overclocker-friendly variant of the ATI Radeon HD 4770 (model: EAH4770 TOP/HTDI/512MD5). Giving it the "TOP" branding, the company upped the clock speeds, and backed the product with its Voltage Tweak technology, and its popular SmartDoctor performance control application. The gains end-users have compared to using a reference design accelerator are two fold.

First, ASUS set the clock speeds at 800 MHz (core), and 850 MHz (memory), both 50 MHz bumps over the reference AMD clock speeds of 750/800 MHz (core/memory). Second, using the value-added features, the voltages can be upped from 0.95 V to 1.2 V, increasing the overclocking headroom. ASUS claims the core could be set at freqencies as high as 971 MHz, and 1150 MHz for the memory: a seemingly massive increment over the reference speeds, which ASUS rounds off as a 35% speed improvement. The card retains the reference AMD design, and the most common cooler design partners are currently using. Its pricing and availability are yet to be known.

The HD4770 is getting more and more bad ass by the hour!

They just need to release some versions with a better cooler.

That asus cooler looks tacky. I am hoping that XFX will do one with an all black slot cooler.

I'm wondering if they'll release one with 256-bit memory and the full 800 shaders.

Call it a HD 4870+. Worked for nVidia.

The Sapphire version has a heatsink on the VRMs, why doesn't ASUS do the same?

The RV740 doesn't have 800 shaders to begin with or the ability to use a 256-bit bus. And when did nVidia it?

Is it a heatsink, or just a crappy piece of metal for them to put their sticker on?

I love the card but I HATE (and this is a first for me) the standard cooler, it looks ugly.
The early one looked much better (the black and red 3870 cooler).

Anyway, give me a single slot cooler and ill Crossfire me way to gaming heaven :P.

XFX already released one with the standard red PCB and silly looking cooler. It's a great card, but I'm holding off a couple of weeks to see if any impressive variant models come out...

If all else fails, slap a Zalman on it and call it a day! :toast:

Has anyone else noticed that the stock 4770 cooler looks like ASUS's custom EAH cooler but with more plastic?
It looks like they couldn't put their custom cooler on this one because that would mean less plastic crap on it.

Also, the heatsink on the vrm area might not be necessary.
the EAH3850 had one, but the EAH4850 doesn't.
Put on one yourself if you're a thermal freak like me :D

Does the voltage control work for their Dark Knight 4870s?

If you hate how the cooler looks you could always remove that plastic bracket......

its just a zalman-style flower cooler. But I agree. WHY THE PLASTIC BRACKET?!??!

The plastic bracket is forcing the air to flow only between the bracket and heatsink providing better cooling;if you take it off your temps increase.

this cooler must be enough for this 40 nm gpu

Eh this is supposed to be a budget card. That cooling is sufficient.

Plenty of "budget" cards in the past have had decent coolers. This cooler gets the job done, but it looks like ass.

The cooler looks nicer in person. I was just at my friends house and he got the sapphire version. It's not THAT bad looking! It works VERY well too. He was getting near room temps at idle and 45-50c load.
