Fixing The Radeon R9 290 With Arctic's Accelero Xtreme III

Temperatures, Overclocking, And Noise

Overclocking And Temperatures at 12 V

So, let’s test the real limits of this card's frequency. We can always dial the acoustics down later. With the R9 290's power limit set to +35%, I figured out that the maximum stable clock rate was somewhere around 1150 MHz using an hour of Metro: Last Light looping 24 times. It only took 10 minutes for each pass to hit its highest temperatures, and I maintained constant clock rates throughout, so there was none of the jumping up and down seen from AMD's reference cooler.

The following chart tracks thermals for the GPU and voltage regulators at two different clock rates.

Overclocking And Temperatures at 7 V

Now we know our overclocking limits (on air, anyway). What happens to the voltage regulators when we dial back fan speed with a 7 V adapter, though? It turns out that GPU stays nice and cool, but the VRM overheats. To maintain safe parameters, we measured everything again at a 1100 MHz ceiling and a +20% power limit. The 1150 MHz we were enjoying before is still possible, but then you're looking at almost-100 °C voltage regulator temperatures.

Real-World Performance Improvement

All of this adds up to an improvement in gaming, quantified by measuring average frames per second. Otherwise, a higher sustainable clock rate on its own doesn't mean much. You'll have to forgive the results with AMD's Catalyst 13.11 Beta 6 and 8 drivers. These numbers were all run before the company adjusted its fan control algorithm in the face of our investigative work.

Between when we received our original press board with AMD's original driver and our more recent overclocking effort using Arctic's Accelero, the Radeon R9 290 picks up nearly 20% more performance. Even after the Beta 8 driver with a 47% PWM limit, the modified card wins by 13%. Of course, by pushing the 290's fan speed even higher using Catalyst 13.11 Beta 9, AMD managed to eke out addition performance. At the same time, however, it made a very loud thermal solution even louder. clock speed gain. Arctic's Accelero Xtreme III gives you even more speed, without the unbearable whining.

Video Comparison Of The Aftermarket And Reference Cooler

First we're going to let you listen to both overclocked versions of our R9 290 with Arctic's cooler at 12 V (1150 MHz) and 7 V (1100 MHz). Then, you can check out the original Radeon R9 290 with its 47% PWM limit that was knocking our press card back off of its 947 MHz ceiling. Remember, Catalyst 13.11 Beta 9.2 makes the board even louder.

We present AMD's Radeon R9 290 GHz Edition, the way it should have been.

  • I want AMD and NVIDIA to start selling their boards without a cooler. I can buy a waterblock from any number of retailers, but I can't get the damned GPU. Discount the boards and sell them OEM to us consumers.

    Also, try and make your layout a standard so I don't have to keep buying after-market coolers or blocks. I can just move them from board to board.

  • I will wait and get the Gigabyte Windforce then I will not have to pay full price for the cooler. (just saying)

  • I can't find anything to confirm that you tested this inside a case, and I'm curious what it does to case and cpu temps compared to the reference card, and what it does to a second gpu running in crossfire mode.

  • I gotta say I agree with AMD's opinion that reference coolers are just there to get the job done as cheaply and consistently as possible since non-references will rule the market anyways.

    But at the end of the day reviewers are gonna continue to mark down cards for these silly things for whatever reason. AMD might as well just make the reference coolers at least as good as SAPPHIRE's Dual-X so that everyone shuts up...

    I've proofed this construction in my Corsair Obsidian 900D and it works as described, I had to turn on my case fans but only @800-900 rpm. To test a crossfire setup I would have to destroy two cards - sorry, but this was too expensive for me. One modified card is ok, but I cant kill all my samples :D

  • that 1150 clock speed is actually on the low side. on several other forums i frequent people are hitting mid 1300's pretty consistently with aftermarket air coolers, and 1400s on water.

    it seems the r9-290x is pretty much identical clock for clock to the 780ti... so putting a non-reference cooler onto it is almost mandatory; because when it's not temp throttling it's pacing nvidia's $700 monster.

  • I was going to say same thing as sha7bot. Overall though I hope one day we can buy a gpu and fan/cooler in drop it in the Mobo socket like a cpu. Hell even have multiple sockets in a row to take up less space at the end of the mobo to give room for pci slot devices. It always sucks having to decide between these graphics cards or "this" card and a sound card or ssd.

  • Maybe, later on the road Accelero will launch a R9 290 version of this cooler as they did with the HD 7900 version.

    Also, look that, that cooler is barely spinning. You can squish more of it, that would be even more noticable in performance gains!

  • "Obviously, if you spend $400 on a new Radeon R9 290 and immediately take it apart, your warranty is void."

    Are all the Vendor's cards like this? If I remember correctly Sapphire used to allow (or still does) people to take the stock cooler off to attach a waterblock without it voiding the warranty.

  • Blimey, that is so much fuss to put together, not to mention the fact that it voids your warranty.. AMD have really, really shot themselves in the foot by not offering after-market cooling at launch.

  • Any chance you could try fitting Nvidia's GTX780/Ti/690/Titan style cooler to the 290/X just to see if it is any better then AMD's design? A lot of reviewers have praised Nvidia's coolers but some claim the HSF is better because the cards draw less power and have a bigger die to spread the heat across, it would be interesting to see who's right.

  • @Igor, how are you monitoring VRM temp? GPU-Z or some other way?

    VRM temps aren't reported for my GTX 560, it seems...

  • I have been leery of, and stopped using, AMD cards after one literally smoked under load a few years ago.

    Switched to nVidia and have been happy. Currently running 660, 760 series in my machines. I did have to retire (put in parts box until I can take apart) an MSI 560Ti Twin Frozer when one of the twins had a bearing fail and quit spinning. The card still works, but not well, in my all air boxes. Gotta love the irony, though.

    The kind of stuff required in this article is indicative of AMD's thrashing to compete; throw it out the door and pray. Pass.

    The BIOS was locked. Without increasing the core voltage my sample runs only 1175 max. It is a lottery which numbers you get

  • This looks like a nice kit. The only question I would have is, how does this perform in an enclosed box? How much does the heat being dumped inside your computer effect the overall efficiency. I don't like to see reviews where the testbeds are open since they don't reflect real world installations.

  • This is a DHE (direct heat exhaust) cooler. If you have an intake fan, you get the same (or even better!) results.

    BTW:
    A good tower case with a well-planned airflow can be a better ambient for VGA cards as an open bench table ;)

  • Why not just leave AMD's PCB Heatspreader on the board and mount the GPU Cooler on top of that?

  • Collision with the heatsink. I've tried this first but it is really impossible without modifying the frame. ;)

  • Waiting for Asus TOP models and Saphire oc versions... All in all this profe that there is a lot of potential in this GPU. And allso that 28 nm is too big for a GPU of 780 and 290 scale...
