The Voltage Tweak model from ASUS is something we've heard about for a while now. The idea behind it is that ASUS gives the user even more control of the card when it comes to overclocking. Not only do you have the ability to overclock the standard clocks like memory and core, but you also have the ability to adjust the voltage. You may be wondering what this exactly means, it gives you the ability to adjust the voltage to higher levels which in turn gives you the ability to run the graphics card at even higher speeds. While this may sound a bit scary to some people, we are sure that ASUS hasn't given you too much control that you could essentially damage your card as that would be a stupid decision. - TweakTown

ASUS Radeon HD 4890 Voltage Tweak Board Preview

Straight away we see there haven't been any real changes made when it comes to the overall box design. And of course ASUS has really highlighted the Voltage Tweak logo to let you know that this video card isn't part of the normal Radeon HD 4890 line up. We can also see the picture of a knight on a horse which is something we see quite often. Across the top of the box we have the ASUS logo while the bottom gives us the model. And above that we have mention of GDDR5 memory and also makes word that it comes with 1GB in total. Turning the box over, there isn't anything we haven't seen before which are merely the features.

With the package done it's time to check out the card and straight away we can see that there isn't really any difference as far as looks go when comparing it to other Radeon HD 4890 cards we have looked at which use the reference design. With that said though, ASUS has of course added their own sticker to the card to let it stand out from other Radeon HD 4890 offerings. We can see the ASUS logo on the sticker and in the center of the fan, we also see a picture of the knight that we saw on the front of the box. As we've suggested, the board follows the reference design, so looking around we don't see anything out of the ordinary.

Now what the Voltage Tweak version from ASUS does is let us expand upon our overclocking abilities. For years the only way you could adjust the voltage on the card was by soldering little bits and pieces to your card, which not only is hard for most people but also voids the warranty. We're not sure if this ability is going to be something we see more and more often in cards, but it would be nice. Even if these companies don't offer us a huge range, just something safe that gives us the ability to gain even more MHz if we feel the need to. As for the rest of this graphics card, there isn't anything too out of the ordinary.

We've got their usual spin, plenty of extra software along with a CD wallet. We've also got all the standard cables that we need to get the card up and running. All in all this Radeon HD 4890 Voltage Tweak from ASUS is an great version of the Radeon HD 4890 which lets us experience something new. Hopefully we do see more of this technology come into play with other models in the future.
