Overclocking

Finally, let’s spend a bit of time looking at the overclocking prospects for the 290. Without any voltage adjustment capabilities and with AMD binning chips for clockspeeds and power consumption we’re not necessarily expecting a lot of headroom here, but none the less it’s worth checking out to see how much more we can squeeze out of the card.

Even though we’re officially limited to AMD’s Overdrive utility for the moment for overclocking, Overdrive offers a wide enough range of values that we shouldn’t have any problem maxing out the card. In fact we’ll be limited by the card first.

Radeon R9 290 Overclocking
  Reference Radeon R9 290
Shipping Core Clock 662MHz
Shipping Boost Clock 947MHz
Shipping Memory Clock 5GHz
Shipping Boost Voltage ~1.18v
   
Overclock Core Clock 790MHz
Overclock Boost Clock 1075MHz
Overclock Memory Clock 5.6GHz
Overclock Max Boost Voltage ~1.18v

Despite the lack of voltage control, when it comes to overclocking the 290 we were able to achieve solid overclocks on both the GPU and the memory. On a boost clock basis we were able to push the 290 from 947MHz to 1075MHz, an increase of 128MHz (14%). Meanwhile we were able to push the memory from 5GHz to 5.6GHz before artifacting set in, representing a 600MHz (12%) memory overclock.  Being able to increase both clockspeeds to such a similar degree means that no matter what the video bottleneck is – be it GPU or memory – we should see some kind of performance increase out of overclocking.

On a side note, for overclocking the 290 we stuck with moderate increases to both the maximum fan speed and the PowerTune limit. In the case of the former we used a 65% maximum fan speed (which actually proved to be more than what’s necessary), while for the latter we went with a 20% increase in the PowerTune limit, as at this point in time we don’t have a good idea for what the safe power limits are for the reference 290/290X board. Though in either case only FurMark could push the overclocked card to its power limit, and nothing could push the card to its fan speed limit. Similarly we didn’t encounter any throttling issues with our overclocked settings, with every game (including CoH2) running at 1075MHz sustained.

Taking a brief look at power, temp, and noise before jumping into our gaming performance results, we can see that overclocking the card has a measurable impact on power consumption under both Crysis 3 and FurMark. With Crysis 3 we’re clockspeed limited before we’re power limited, leading to an increase in power consumption of 27W, while under FurMark where we were power limited it’s a much more academic increase of 87W.

Since the 290 already ships at the highest temperate limit it allows – 95C – our sustained temperatures are unchanged even after overclocking.

The 290 is already an unreasonably loud card at stock, and unfortunately the fan speed increases needed to handle the greater heat load from overclocking only make this worse. Under Crysis 3 we peaked at 59.7dB, or 49% fan speed. While under FurMark we peaked at 65.3dB, or 59% fan speed. For these noise levels to be bearable the 290 really needs to be fully isolated (e.g. in another room) or put under water, as otherwise 59.7dB sustained is immensely loud for a video card.

Finally getting to the matter of game performance, we’re seeing consistently strong scaling across every game in our collection. The specific performance increase depends on the game as always, but a 14% core overclock and 12% memory overclock has netted us anywhere between 9% in Metro up to the full 14% in Total War: Rome II. At this performance level the 290 OC exceeds the performance of any other single-GPU card at stock, and comes very close to delivering 60fps in every action game in our benchmark suite.

    Just in time for Xmas! Brilliant. I think the rest of you guys should really avoid this card because of the noise. It is horrendous. Do not buy this card no matter what you do. I of course will buy two of them myself, since they will be totally emmersed in a mineral oil/nano-diamond slurry that can be pumped through a tank in an old ice cream maker I now use as a chiller. All set up in a hand made solid copper tank I scavanged from an old still, and looking quite steam punk with oversized analog gauges and big old hand set revets and such. Not a laptop. Completely silent when the compressor is not on. The compressor really isn't needed for a decent overclock with a few hundred pounds of copper pennies suspended less than an inch above the MB components, bathed in the same nanodiamond slurry. Total silence, except for my gaggle of hard drives when they are on. I have been waiting for you Radion 290, I will freeze your nuggies off, with no sound at all. Ah ha ha (simulated mad scientist laugh) Why pay the big bucks for a little nanodiamond in your transformer coolent when you can use food grade mineral oil and lots of nanodiamonds. Nanodiamonds almost rule for heat conduction. Way way better than metal of any kind. And they lubricate any mechanism they flow through. This is why the very best heat pipes contain nano diamonds in their working fluid. As little as one half of one percent to four percent nano diamond make huge gains in performance. Can't give exact figures if interested look it up.

    having read many articles on the noise of this card R290, I have no problem with it being slightly loader than my old 7850. I set at work with an old IBM 4227 DOT Matrix Printer that prints like a Locomotive going by, with the wistle Blowing - that can be nerve and hearing shattering. As for the heat, after 4 days of use, the only problem can be with intense play on games such as Rome Total War II, and Battlefield 4 at highest setting - does get warm. The Sapphire Card I have is fine other wise. The vendors do need something with a better cooling ability. Perhaps, trying Water Cooling, or multiple fan solution. Oh BTW, can be used as a reserve of heat in cold climates during the winter!

    I see a lot of performance praise here but I also see that people are not really aware that this thing runs 10 degrees hotter and 7db louder. It might not seem big of a difference in numbers but its BIG!

    This card is quieter than my GTX465 which I have been using for a couple of years.

    Why wouldn't I buy it? LOL

    It is all relative.

    Definite buy on this!!!!!!! Can't wait!!!!!!! Time to sell my GTX 670 and bought this instead! Arghhhhhh... Thanks AMD!

    I installed the Gigabyte variety of this card over the weekend and ran Bioshock Infinite and Crysis 3 over a period of several hous while actually playing the games.
    It sits in a HAF-X case under my desk. For sound I use simple ear buds, sometimes in only one ear because the missus has imporatnt things to communicate at randomized intervals.

    And I'm calling bullshit on the noise issues. Yes, there is a clear difference between idle, MS Office and Crysis 3 applications. But at no time whatsoever the noise was excessive or annoying. This may of course be different if you run an open testbed on your desktop.

    But for a regular install in a closed case I cannot fault it. In fact, the Gainward GTX 570 GS installed in the Antec P182 case that SWMBO's desktop uss is a hell of a lot noisier.

    If I were a conspiracy theorist I would suspect Anandtech was looking for an excuse to sink this brilliant piece of AMD hardware.

    Damn happy I bought mine! and get rid of my GTX 670. 70-80 average fps and 100++++ max fps in Battlefield 4 on ULTRA is a pleasure! :DD

    Have the CF Eyefinity drivers with frame pacing been released yet? Or should I just ask will they be released?
