Sapphire Radeon NITRO+ RX460OC 4GB 11257-02-20G Review

TRIXX Overclocking and Card Utility

Sapphire TRIXX 3.0 is what I used to overclock this card and raise the fan speeds, but how does it work?  I will show you here and maybe help you when you get this card overclock it some.  Please only use it for reference, not all cards clock the same. For those of you learning, I will just quickly breeze over it.

The way I recommend doing it is to start from the bottom, start of your tests at stock, and slowly increase taking notes as you go.  Please take note, this is my approach, everyone has their own approach to overclocking.

Here is again the overclock shown from within TRIXX 3.0 itself.

The stock clocks here if you remember were 1250Mhz on the GPU and 1750Mhz on the memory, so we have come up a bit and it did take me some time and lots of failed attempts to get here.  I am sure I could have gone higher but for times sake I present you with the above, a decent overclock I would say.

To start here, raise your GPU Clock 5Mhz and then click “Apply” then run a round of “3DMark” and a benchmark of one of your most graphically intense games, I use “Metro Last Light”, it catches mostly everything wrong with an overclock.  Actually this time, Ashes of the Singularity caught a mistake and it was my 2nd to last benchmark, once I found the mistake I had to redo all of my results, that took an extra day.

Once the results are in, write them down then raise 5 more Mhz and repeat the process.  If during your testing the machine freezes or you notice artifacting or tearing (spots appearing on the screen, missing or stuck textures) then it’s time to raise the “Power Limit” bar and if that fails then also raise the GPU Voltage and test again.  Make sure with all changes you make to click “Apply” and write it down.

Be careful with the GPU Voltage, if you raise it too much you can potentially damage the card, but on the lighter side you will eat up a lot more power needlessly.

68

As you are raising the GPU Clock, you will also want to work on the Fan Speed.  I recommend clicking “Custom”, which opens up the “Custom Fan Speed” section where you can raise/lower the fan bar.

69

Check out exactly how to use it and how loud the cards get

Once you have reached a stable GPU speed and achieved adequate cooling then I recommend you start working the same process on the Memory Clock.

Save your work often, you can do this on the profiles.

70

Click on any one of those numbers and click “Save” the settings.

71

Use the same methods for Memory Clock that I mentioned for GPU Clock.

Here you will raise the “Memory Clock” slider

72

And like before, click “Apply” to apply the settings.

One thing to mention about overclocking on Sapphires TRIXX 3.0.  When you restart your computer, at times the “GPU Voltage” will appear to be “0” as well the “Power Limit” setting. This is probably occurring since it is a beta, it’s not perfect yet but it is good but it is a quirk.  The version I used here was v6.1.0.

If you do notice the 0, just click on the “Profile” you have saved your overclock to and click “Apply”, this will set everything as you last saved it.

TRIXX gives you a few more features, I will list them here.

FanCheck:  A utility built into Sapphires TRIXX 3.0 that allows you to check the life of your fans, since you are actually able to easily replace these fans.

73

This will individually check each fan, or it should.  In this version I see that it only shows 1 fan.  I spoke with Sapphire support and they mentioned that TRIXX for now is considering this card as a reference card, the reference cards from AMD only have a single fan but they are working on updating TRIXX to properly show both fans here.  I can assure you from my testing both fans are working properly; you will actually be able to see them spinning in some thermal photos I took below.

74

Once the test has completed, it will let you know that status of your fans

Under the settings button, we find a few more things.

75

76

Settings allows you to show “Effective Memory Clock”, “Synchronize CrossFire Cards”, “Set clock on Change”, “Save Fan Settings with Profile”, “Disable ULPS (ULPS)”: Ultra Low Power State: a sleep state that lowers the frequencies and voltages of primary and non-primary cards to save power, it can also cause instabilities with Crossfire and single card configurations).   The other settings are to be able to “Load on Windows Startup”, start TRIXX minimized and restore clocks.

There is also “Graphics Card Info” which shows you information for the card.  Most of the information is static information, if anything changed when overclocking it would update.

Here are the stock settings:

77

Here are the overclocked settings:

78

This also allows you to save the current bios by clicking “Save the BIOS” to store for your own purposes, give to a friend, share with the community or maybe adjust using another piece of software and flash back to the card.

Hardware Monitor, allows you to see all of the specs of the card in real life, as you are overclocking and maybe running through games and benchmarks. Here you can see where the voltages are maybe if the benchmark fails, then make adjustments or if maybe the voltages are needlessly high, you can adjust looking through here as well.

79

“Log Now” allows you to create a log to save your metrics to of your Sensors.  Its output is similar to that of GPU-Z.

To keep costs down, they did not include an RGB lighting scheme on this card, but they did throw in some bling.

80

81

The back of the card has a NITRO logo that shines green through the PCB of the card.

Benchmarking builds up heat, I was able to use thermal imaging to see how the card reacted on each piece of the card.  I used the Seek Compact Thermal Sensor that I will be reviewing soon to get this information.

82

This is the top of the card, and the picture was take with the system idle.  The white area’s on the card are the hottest parts of the card.  You can follow the legend on the left hand side of the picture to be able to tell the temperatures.

83

This is the bottom of the card, the hottest part was 34°C.  You will also notice that the fans were not spinning since the card was not being being used really.

84

This is the card running 3DMark on Firestrike Ultra.

85

Here is the bottom of the card seconds after taking the pic of the top of GPU running 3DMark.  The bottom will really not show the heat like the top will since the top is just behind the GPU and the heatsinks are absorbing that heat, the GPU here is covered by the card housing and being actively cooled by the fans.

I also recorded this, so you can see it in action

Sapphire did a great a great job with their Dual-X Cooling keeping the card cool.

Well, now its time to see what I thought overall and to see if you agree with my opinion.
