Designed for Serious Overclockers

Designed for Serious Overclockers

It's not an ROG product without some really cool features for the hardcore crowd. Firstly, there's what ASUS calls Mod Zone that caters to the extreme overclockers who practically rip out the standard coolers for their own liquid-cooled versions (we're talking LN2 capable ones here). On the PCB, there are clearly marked solder pads that when soldered, enable rather risky things like removing the built-in safeguards for overheating and overcurrent. That's the 'Disable OCP' marked on the PCB below. The Power PWM Freq meanwhile doubles ASUS' Super Hybrid Engine (its power management IC) clock on this card to provide stability even under high clocks. The other two contact pads allow the adjustment of memory voltage and PLL voltage. This is definitely not for beginners. 

These solder pads here are meant for the hardcore crowd. The 'Disable OCP' here basically removes any last safeguards on this card. Recommended only if you are using LN2.

Then there's ASUS Probelt. It's a feature that we have seen for a while on ASUS' ROG motherboards, but it's the first time we have seen it on an ASUS graphics card. Basically, it's a set of voltage measurement points where enthusiasts with the inclination and a multimeter can just poke their sensors and check the voltage of the memory, graphics core and PCIe bus.  

With a multimeter, you can also measure these voltages (GPU, memory, and PCIe bus), similar to what's available on ASUS' ROG boards.

If you need a quick fix for your cooling issues, just press the red button. It instantly pushes the fan speed to 100%, which is pretty loud. The other two buttons, the plus and minus allows users to adjust the core voltage directly, without going through any software utility.



Perhaps ASUS saw the success of MSI's Afterburner utility that has become popular among enthusiasts to tweak their graphics cards. If that was indeed the case, then the GPU Tweak is the response. On first glance, it's similar to the more powerful tweaking utilities out there and there's even a re-skinned GPU-Z that shows the key specifications of the installed graphics card.

What's important to most enthusiasts is that they can control the voltages, clock speeds and fan speeds easily and GPU Tweak's main control panel provides that. It can even lock the clock speeds and voltages such that when the user changes the core clock slider, the core voltage changes correspondingly. It's a nice touch for the less experienced users who may not have any clue to the appropriate voltages.

While GPU Tweak isn't hard to figure out for anyone who has previously tried any software tweaking utilities, we felt that it could do with more tooltips that explain in slightly more detail what each feature does. At the moment, the tooltips when they appear, just seem to state the name of the function/feature, without more information. The real-time monitoring panel (the left panel below) also seems to launch slower than we liked, but that's a minor quibble.

If you really like your tweaked settings, the GPU Tweak has a special BIOS Burn-in feature where your favorite clock, voltage and memory timings for the graphics card is saved in its BIOS. This means that your graphics card will start booting up with these custom settings. The catch is that this is only available on supported ROG graphics cards like the Matrix GTX580 Platinum, presumably because it has a Safe Mode feature in case users really mess up the BIOS with this Burn-in function.

The GPU Tweak also has a built-in recording feature, but it doesn't appear to be working when we tested it. ASUS has said that it's coming soon and with MSI's Afterburner also adding a similar Predator, video-capturing feature, both companies are competing to bring enthusiasts the best tweaking utility. And for free!  

You can expand up to three panels with the GPU Tweak utility, a main control panel, a monitoring panel and the ASUS' reskinned GPU-Z. Click on image to enlarge.

One advantage of GPU Tweak that ASUS is touting over rival tuning utilities is the added option to change the memory timings on the graphics card. In our experience, memory timing options bring little benefit these days, but that's what the ROG product is all about - pushing the capabilities to the max.

The settings for the Tuning page where users can customize what they see on the control panel. As you may tell from the other tabs here, other features include a realtime Recording utility for games and screenshots, Live Update to keep your driver and BIOS updated and of course hotkeys to trigger the recording.
