OK, so before I provide the results, let me show you how I got there.  First off, this is not a quick thing, to overclock correctly, you have to spend a few hours, have some patience, a paper and a pen because you will be there for a while recording your previous attempts.

Below, I will list before and after results of course of benchmarks but I will show reports from Sapphires TRIXX 3.0 and GPU-Z.

I was able to get 106Mhz from the GPU Clock and an impressive 250Mhz from the memory clock.  With that, I was able to raise my bandwidth, pixel fill rate and texture fill rate.  Surely I could have gone much higher, it was a great overclocking card, but I didn’t want to waste too much time overclocking, I wanted to give you my clocks and even confirmation as a reference.  Please remember, if you buy the same exact card, the performance and overclockability may not be the same, yours may be able to clock higher or not very high at all, it’s the nature of the beast.






I modified the GPU clock


Then also raised the “Power Limit”


Also the “GPU Voltage”


The “Memory Clock”


And finally the “Current Fan speed”



This program does more than just overclock the card, but I will get into that a little later in the review.  Let’s get into the comparisons.



The performance difference here is pretty nice; we can see a 365 point increase in 3DMarks, a 6.60% improvement.  The average wattage consumption increased as well as you would have imagined 24.78% from 152 Watts to 195 Watts, but we did raise the voltage quite a bit there.  Also, the temperature went down 10 degrees, because now I had control of the fan, it was a little louder but with the side panel on it was barely noticeable.

For the games, I will be pairing the tests based on resolution, keeping things relevant and basing the scores only on average FPS since min and max do not mean as much.

With that said, let’s see what this means for Metro Last Light.




From this overclock we can see the average only went up a single FPS and on the flip side, the temperature went down a single degree.  Wattage on the other hand did go up about 13.38%.  Sadly still not playable, but let’s see what 1920 x 1080 brings.



Well, at 1920×1080, we increased FPS only 2.04% and yet again the temperature did from 66°C to 53°C, a 21.85% decrease in thermals, always a welcomed treat.  Since we did raise the voltage, we pulled an additional 2.61% more power on average which is not too bad.  Now onto 2560×1440.



I didn’t expect 2560×1440 to be any better and well I was not disappointed. There was an increase of FPS .34 FPS, a 3.24% improvement.  Due to the custom fan control, the temperature dropped 67°C to a pleasant 53°C, a 23.33% increase in thermal performance.  Now you will notice the wattage did drop, lower temperatures usually means lower power consumption and we can see that here.  On average the stock Sapphire Radeon RX460OC pulled in 255 and with a little extra umph we see that it dropped 3 watts a 1.18% decrease in power being consumed.

Thief will pick us up and take us, though I don’t know where.




Thief for now has stolen the show, making the PC fun again and bringing much more playability.  We started off at 53.3FPS and with the overclock, we have gone up to 55.5FPS a 4.04% increase in performance.  With that, we see that the temperature dropped 19.67% below the stock temperature of 67°C though the wattage did increase 3.69% to 276Watts.  Let’s see if a resolution of 1920×1080 produces playable results.



While the FPS here is not 60FPS, this can get so much better just lowering a few things.  Aside from that, we did see here an increase from 40.3FPS to 41.7FPS, a 3.41% improvement and with that, the cooling dropped a considerable 25.40% from 71°C to 55°.  Power draw did go up from 268 to 275Watts, a 2.58% increase in power consumption.  How about 2560×1440?



Ouch, while there was an improvement in the overclock by 4.46%, it was a very tiny one that does not make too much of a difference.  Keeping up with the trend, the temperature did drop 19.35% and though the average wattage being used went up 3.69.

In Thief, we saw things much more playable and the temps at a great place; let’s see how Laura reacts to this increase.




Laura takes care of us, giving us a smooth 65.2FPS, 6.33% above the stock 61.2FPs and with that she gives us the cold shoulder at a chilly 51°C a 25.64% improvement in cooling over the stock 66°C.  The wattage did go up a bit consuming 7.53% more power than its stock counterpart.  What does 1920×1080 hold for us?



At 1920×1080 we can see a 5.49% improvement from 46.1FPS to 48.7FPS.  An increase in performance is always welcome and it will make it a little more playable but at 48.7FPS you will notice a little stutter.  The temperature did decrease improving the temperature from its base 67°C to a nice 53°C but the power consumption shot up a bit from 227Watts on average to 244 Watts an increase in power usage of 7.22%.  Ok, last but not least, let’s see what 2560×1440 can do.



2560×1440 for a budget card is a bit rough and she did what she could bring in 32.1FPS over its stock 30.2, a 6.10% improvement.  The power did go up as well coming up at 7.13% more watts being pulled but she did stay at a nice 54°C, a 20% improvement over its stock counterpart coming in at 66°C.

Let’s continue with Ashes of the Singularity, and hope for out of this world performance.




Ashes is really a rough benchmark to gauge, the results are not very telling.  In this, the CPU compensates for the lower end GPU and to top it off, it is running in DX12 so it helps that much more.  We can see here that the CPU, while not overclocked at all jump to 97.7FPS and the GPU jumped to 16.3FPS, a 6398% improvement on the GPU side.  The temps did drop yet again from 66°C to 54°C and the power consumption did go up 14.14%.

The game was pretty smooth here, but when all of the ships got together, you can see that she struggled a bit.  Let’s check out 1920×1080.



The overclock here turns up an additional 0.5FPS, but in the Average CPU Framerate, we can see a huge 17.8FPS increase.  Not getting off of subject here for the GPU, but I thought I would mention it.  The temperature took a nice drop from its pretty high 71°C to a very comfortable 53°C, a 20.92% improvement in cooling.  OK, on we go to 2560×1440.



At 2560×1440 we gain .5FPS but the CPU steps in an covers coming in a 86.7FPS, 16.8FPS above the stock 69.9FPS.  As usual, the temperature dips well below its stock 71°C at a very cool 54°C but comes up 3.19% above the stocks 247Watts, pulling up to 255Watts.

Ashes of the Singularity was a tough one, at 2560×1440 almost unplayable but let’s see if Tom Clancy can bring it back with The Division.





The extra overclock provides an additional 3.76% performance at 37.9FPS above the stock 36.5FPS, not too much but every bit helps.  Power consumption goes up 4.99% at 267Watts above its stock wattage of 254Watts.  Let’s check out 1920×1080.



At 1920×1080, the CPU swoops in to try and give the GPU a hand, raising itself from 16FPS to 21FPs while the GPU bumps itself up slightly at 30.5FPS, a tiny 1.32% increase in performance beigning at 30.1FPS on stock.  The temps on this one at stock came in high at 70°C and on the OC a nice 55°C, a 24% improvement but the power got hit again.  The average consumption at stock was 258 Watts on average and overclocked came in at 277 Watts, a 7.10% increase.  Last on the benchmarks is 2560×1440.



This is a bit of an odd one, everything at least on the performance side decided to improve by one or at least very close to it.  The Average CPU FPS increase by 1FPS, the Average FPS improved by .9, a 4.28% increase in performance and there was yet again an improvement in cooling as well.  The stock clocks heated the card up to 70°C and the overclock settings brought it to much more manageable 55°C, a 24% improvement in thermals.  Needless to say, the average power consumption went up from 256Watts to an overclocked 267Watts, a 4.21% increase in power use.

We can see in these results throughout the benchmark section that the GPU did pull its weight in situations that make even higher performance cards sweat a bit.  With all the eye candy on, mostly every test performed well at 1280×1024, which means that with the eye candy down a bit, 1920×1080 will play just fine in most games.

So lets take a moment and see how we were able to obtain these clocks.
