Sapphire Nitro 390 Overclocking

There are many tools available that allow overclocking the GPU, Sapphire has their own tool called TriXX.  This tool lets us know what is going on with the GPU and an easy way to overclock or adjust fan speeds.  The overclocking tab is laid out so we know what can be adjusted and is a great way to know exactly what is going to happen.  The VDDC Offset is a little tricky, it started out at 12 and could be increased to 18; from 19 – 22 it would revert back to 18, then it would jump to 25 for a while.


Sapphire Nitro 390 Overclock


Increasing the GPU Clock in 10MHz increments, and running 3DMark we were able to achieve a maximum OC of 1210MHz before the system became unresponsive, before getting there above 1160Mhz we started having graphic issues.  Increasing the VDDC Offset to 25, our final overclock was 1183 without any graphic issues.  Next we started increasing the Memory Clock, using the same method, at 1790MHz the system was flawless, anything above that we started  having issues with lock-ups.


Going from a base GPU Clock of 1010MHz to 1183MHz is a 17% increase.  While the Memory Clock went from 1500Mhz to 1790Mhz, a 19% increase!  Not a bad boost in clock speeds.

Sapphire Nitro 390 Overclocked (1183MHz / 1790Mhz)


With a 17% increase in GPU Clock speed and a 19% increase in Memory Clock speed, we saw that translate to a 608 point increase in 3DMark Fire Strike Extreme.  That represents a 12.5% performance gain!  As we will see shortly the sound level of the Nitro 390 did not change much during testing.  Even when overclocked, the noise level did not increase anymore than it did during standard load testing.  The temperature however went up an additional 8C, reaching 59C at it’s peak when overclocked.

    The NVidia/Intel Circle Jerk is at Noon Tomorrow. Same goes to all the other people that refuse to research the R9 300 series cards and actually learn the real information on them rather than post generic BS stories about how there is near zero differences from the 200 series. The 200 series dont even come close to 300 series. 300 Series Run DX 12 and Vulkan. A 280 or 290 will never be able to such thing, they lack the architecture.

    54 degrees Celsius at 100% load? If so, what were the fan speeds? Everyone else seems to be getting high 60’s low 70’s…

    • drake1988

      You should check what this diagram rly is showing :D.
      Instead of 54° you should read it as 54Watt and its for the complete system, not the gpu only.

      • Sai

        r u fricking stupid it says temperature in Celsius and dou have common sense, 54 watts for the entire system r u out of our mind

    • Vicken Boghossian

      Yea im shocked too how they got that low. I just got mine with an ambient of 25C and i just changed the thermal paste to noctua so far i got 61-62C. Once my room cools down (no ac in my appartment) at 21C i should be at 57-58C. Thats with a custom fan curve at 60C its at 50% fan. Above 60% they def get audible. My guess is they tested this in a very cool room, and my guess is the water cooler for the CPU helps a ton, that case must have no heat inside it from a cpu cooler.

      • Steven Kean

        Take a look at the fan speed on the 390, it was running very high even at 30% it was at 3800RPM. As for the audible portion, in the Sound Testing section, I mentioned how loud the 390 is, and that I don’t think the IFC was working correctly on the sample. My guess is that without the IFC working right, the fan speed was jacked WAY up causing the temperatures to be lower than expected. I did try to adjust the fan speed, but it was either off, 3800RPM or slightly faster at 100%. I see the noise chart isn’t showing up for some reason though.

        • Vicken Boghossian

          For me 3800rpm is 100% fan speed and i can agree that it sounds like a jet taking off haha. But your Sapphire Tri-x is also a lot lower then most reviews ive read. I absolutely love my r9 390 though. Overclocked at 1100/1600 im at about 66C. Stock clocks of the new Nitro at 1040/1500 it peaks at 61-62C with the fan at 50%. Its even lower when i use Vsync usually stays well below 60C. Its shocked cuz thats about the temp my 7850 used to stay it haha.

        • 姫佐恵

          Nitro TriXX out of box OC’d. They will decimate even the highest overclocked 290X. In Fact, the TriXX Nitro out of box is running the same clocks as the 390X while 100USD cheaper. Not bad. Plus all of the Direct X 12 and Vulkan on top of that.. Sapphire has pretty much nailed the efficiency of this 390 OC card.

  • Alexandria Jeans

    Hopefully they preform better then they look which isn’t quite that good. Looks like it has a police checker design pretty lame to be honest. also why the hell is it underclocked 5mhz less then base clock of the 380 in general what was it to achieve exactly?

  • Maxime Litteri

    not working for me, games crash immediatly 🙁

  • AMDerpIDIA

    When will reviewers learn to include overclocked gaming benchmarks?

    • Alexandria Jeans

      Because not everyone that values the warranty and longevity of their video card overclocks.

      • AMDerpIDIA

        Fair point. However, I think we all can agree that most of this audience overclocks. It is free performance, and can have a huge impact on performance.

      • Al Bacione

        Warranty, at least on my Gigabyte R9270x, covers OC, cause they’re selling an OC product,u should OC it under warranty terms. It doesnt make sense you wont OC an OCable Gpu to prevent warranty issues, just because warranty asumes it

      • 姫佐恵

        it doesnt void warranty when overclocking. That is why there are dedicated OC models already setup from factory. Unlike 10 years ago, there are too many protections preventing any failure due to overclocking, that is why it doesnt void warranties anymore.

  • Brian Blair

    It’s looking like AMD is trying to pretend these new cards have better performance when all they did was overclock old cards!

    • Jordan Pedeferri

      Load of rubbish

    • Jordan Pedeferri

      This is a refresh, not a rebrand.

      • 姫佐恵

        and honestly, one can hardly call it a refresh. There is just a ton of changes beyond that basics most people know of. Especially the DX 12 and Vulkan capability, which no 290 will ever be able to accomplish. 290’s are older technology and will not get updates like the 300 series will because they cant run the same code.

    • 姫佐恵

      Yea, show me ANY 280/290 card that can run Direct X 12 and Vulkan for starters. Show me a 8GB VRAM. Oh yeah, by the way, The NVidia/Intel Circle Jerk is at Noon Tomorrow. Same goes to all the other people that refuse to research the R9 300 series cards and actually learn the real information on them rather than post generic BS opinions about how there is zero difference from the 200 series.

  • Kim Mark Lewis

    HDMI 1.X or 2.0? That matters to many people like me.

    • Guest

      HDMI 1.4(a)

    • swing84

      The only thing HDMI 2.0 is useful for is 4K, and the vast majority of gamers use lower resolution monitors, so they will not be affected, still, I would like to have seen HDMI 2.0 on this card, even if 4K gaming will be best on the Fury X, Fury and GTX 980 Ti

      • 姫佐恵

        and even at 4K, v1.4 is adequate unless your running a 25 or 30 meter HDMI cable. v2.0 is actually only performance valid for 5K resolutions.

  • Mr Ink 5000

    ok, what i done get is, how can a card come in 2GB or 4BG versions
    do the restrict 2GB on the 2 GB models?

    • swing84

      God help us. I hope this is not a typical American high school graduate trying to speak …

      • Mr Ink 5000

        Thanks for your comment. It said a lot more about you than it did me.

        • Sh Prishtina

          No actually it said everything about you.

        • Mr Ink 5000

          Thanks for ya contribution pal.

          Both of you have had really interesting things to say about a 4 day old comment.

          Instead of taking an opportunity to help someone understand, you thought it looked good to just be insulting.

          Good day.

        • Mr.S

          You people are beyond obnoxious and moronic, its clear that the r9 200 series will be lacking many new features that are supported in the 300 series, unless you already own a higher end card which wasn’t worth buying back then anyway. It does suck on AMD’s part but there is much more to look at then just what it seems to be.
