How to ‘increase/ Max/ Optimize/ Boost’ AMD RX 580 8GB Gaming + Mining: Overclocking/ Best Settings/ Ether /MSI Afterburner Settings/ Hashrate/ How to tune RX 580 for mining: We will overclock AMD RX 580 8GB for mining using MSI Afterburner. You can find it in Yandex. The program interface is very simple, albeit a little colorful) To overclock the video card, we need two sliders:

• Core Clock – overclocking by the core, increases the core frequency;
• Memory Clock – memory overclocking, increases the memory frequency.

MSI Afterburner – Overclocking Video
Cards You need to change the frequency values ​​a little at a time. Then test the stability of the work. If all is well, then we increase the frequency even more. If the video card starts to malfunction or the driver crashes, then we just reduce the frequency and that’s it. There will be no harm. Next, we will look at the overclocking parameters for the popular alogorites.

How to increase AMD RX 580 8GB Mining: bOverclocking AMD RX 580 8GB for Ether

Search prices in the iXBT.com catalog

The PCB is redesigned and differs from the reference design.

The power system received 4 phases for the GPU and 1 phase for the memory chips, and is controlled by the On Semiconductor NCP81022 digital controller. The accelerator is manufactured using a set of high quality Black Diamond 4 chokes, which, according to the manufacturer, heat up 15% less than the previous generation.

The proprietary utility allows you to control the frequencies of the card and monitor the state of the accelerator.

In the overclocking mode (by default), the frequencies of this accelerator are increased relative to the standard parameters of the reference card by 2%, which can provide a performance increase of 1.5% -2% depending on the resolution and operating mode (that is, it is impossible to notice it).

Noise measurement technique

• The room is noise-insulated and damped, reverberations are reduced.
• The system unit, in which the noise of video cards was studied, does not have fans and is not a source of mechanical noise.
• The background level of 18 dBA is the noise level in the room and the noise level of the sound level meter itself.
• The measurements were taken at a distance of 50 cm from the video card at the level of the cooling system.
• Measurement modes:Idle mode in 2D: loaded internet browser with iXBT.com website, Microsoft Word window, a number of internet communicators.
• 2D mode with movie viewing: SmoothVideo Project (SVP) is used – hardware decoding with insertion of intermediate frames.
• 3D mode with maximum load on the accelerator: using FurMark benchmark.
• The assessment of the noise level gradations is carried out according to the method described here: 28 dBA or less: the noise is hardly distinguishable even at a distance of one meter from the source, even with a very low background noise level. Rating: minimal noise.
• from 29 to 34 dBA: the noise is discernible already from two meters from the source, but does not particularly draw attention to itself. It is quite possible to put up with this level of noise even with long-term operation. Rating: noise is low.
• from 35 to 39 dBA: noise is confidently different and noticeably attracts attention, especially in a room with a low noise level. You can work with this level of noise, but it will be difficult to sleep. Rating: average noise.
• 40 dBA or more: such a constant noise level is already beginning to annoy, you quickly get tired of it, you have a desire to leave the room or turn off the device. Rating: noise is high.

In idle mode in 2D, the temperature was 37 ° C, the fans were not working. The noise was equal to the background noise – 18.0 dBA.

When watching a movie with hardware decoding, the temperature rose to 46 ° C, the fans did not work. The noise was equal to the background noise – 18.0 dBA.

Under maximum load in 3D, the temperature reached 76 ° C. At the same time, the fans spun up to 1274 rpm, the noise rose to 25.0 dBA. This CO can be classified as quiet (the noise level is minimal).

Thermal image

The greatest heating is on the back side in the GPU area.

conclusions

Commentary on iXBT.com Ratings

The RX 580 is a direct competitor to the GTX 1060 6GB and looks great in this comparison. The rest of the competitors close in level are also slower.

Commentary on Utility Ratings

Due to the massive obsession with mining, upper and middle-level video cards were massively sold out, a severe deficit was formed, so prices skyrocketed. Now the prices are gradually returning to an adequate state, and we even managed to find the RX 580 on sale at a more or less normal price (although we are not sure if this was not a one-off case). And given the normal prices, the RX 580 has an edge in its group in our ranking.
Sapphire Pulse RX 580 8GD5 (8GB)

Is a great variant of the Radeon RX 580, with slightly better performance than the reference card and a very efficient and quiet cooling system. The presence of 8 gigabytes of memory provides good potential for today’s powerful games. The accelerator also demonstrates excellent value for money (subject to value for money).

The final decision traditionally remains with our readers (look at the current prices below!).

How to Maximize Hashrate: AMD RX 580 8GB

We have compiled an AMD RX 580 8GB hashrate table for popular algorithms. If you are just choosing a video card for mining, and you already know what kind of coin you will mine, then you can estimate the approximate performance from the table. We also have an article on what a hash rate is.

Review and testing of the Sapphire Nitro + Radeon RX 580 4GB video card. Comparison with GeForce GTX 1060 6GB

Returning to the current confrontation between middle-class video cards. The hype from miners has led to scarcity and overpricing of the Radeon RX 580 and GeForce GTX 1060. But these graphics adapters are still in demand among a wide range of consumers. In this review, we will look at the budget version of the Radeon RX 580 with a reduced memory size and at the same time conduct a new comparative test with the GeForce GTX 1060, adding new games to the list of tests. Test applications include the main hits of the fall (Assassin’s Creed Origins, Wolfenstein II), the new role-playing game Kingdom Come: Deliverance and other projects

The focus is on the Sapphire Nitro + Radeon RX 580 4GB (11265-07) video card, which has not only a reduced memory size, but also non-standard frequency characteristics. Let’s see how well it competes with the GeForce GTX 1060 6GB in Full HD resolution, for which all tests will be accompanied by comments on video memory load. Well, we will definitely check the overclocking potential.

Sapphire Nitro+ Radeon RX 580 4GB

The Sapphire graphics accelerator came to us without factory packaging in a regular box, so let’s move on to examining the device itself.

Video adapter 25 cm long, occupies two expansion slots. The cooling system is equipped with two fans, thick heat pipes peep out on the sides.

The plastic case has pseudo-perforation, which visually looks interesting. The fans feature the Sapphire Nitro logos. Outwardly, it is very similar to the Sapphire Pulse Radeon RX 580 8GD5.

A large, illuminated Sapphire logo is located on the side of the casing. Also, two large heat pipes stretch along the edge.

The back side of the board is covered with a metal plate with a geometric pattern on the surface. In a small niche there are two power connectors – six and eight contacts.

The rear panel has five connectors for image output: two DisplayPort and HDMI, plus one DVI. Sapphire Nitro is specially equipped with HDMI pair for easy and quick connection of a VR headset.

Let’s take a look at the cooling system with the shroud removed. This is a rather large heatsink with four heat pipes – two with an increased diameter of 8 mm and two of 6 mm each.

The heatsink has a large base that contacts the memory chips. In the center there is a copper plate that removes heat from the graphics chip. Also on the heatsink there is a ledge with a soldered plate, which is a contact pad for VRM elements. So a single cooler removes heat from all elements on the board at once.

On the reverse side of the board, in the VRM area, there is a contact with the reinforcing plate. For this there is an additional plate, which is pressed to the board through a large thermal pad. Thermal paste is applied to the top of the plate, which improves contact with the backplate. We saved a little on the paste itself, but such a careful approach to cooling the power supply unit inspires respect.

The PCB resembles a Sapphire Pulse Radeon RX 580 8GD5 with boosted power. High quality electronic components are used, in particular, special ribbed chokes and black polymer capacitors.

The GPU power system has six phases.

The GPU crystal is surrounded by a large protective frame.

Eight Elpida W4032BABG-70-F memory chips are soldered. Such chips can be found on the Radeon RX 570. Unfortunately, we have not preserved a good complete image, below is a collage of two fragments, which shows the marking.

The video adapter operates at an increased core frequency of 1400 MHz. The memory operates at an effective frequency of 7000 MHz, which is typical for a Radeon RX 580 with 4 GB, while older versions with 8 GB operate at 8000 MHz.

It should also be noted that the official specifications of Sapphire Nitro + Radeon RX 580 4GB indicate an even higher core frequency of 1411 MHz. Perhaps our copy differs from the current versions in the BIOS firmware. In any case, this 11 MHz is not a critical value.

Under gaming load, the video card showed stable 1400 MHz in almost all games. The most noticeable drops to 1375 MHz occurred in Subnautica (bottom left screenshot). On an open bench at 23 ° C indoors, the video card core warmed up to 69-73 ° C. In this case, the fans worked in the range of 1400–2200 rpm. Everything depended heavily on the load in each individual application. As an example, below are screenshots of monitoring parameters in Subnautica and Kingdom Come: Deliverance.

Please note that temperatures are below 70 ° C. But when passing several runs of the Assassin’s Creed Origins benchmark, the core reached 73 ° C with a fan speed of 1200-1400 rpm.

As a result, we can say that in games the video card shows moderate temperatures and often works with little noise. However, under more severe operating conditions inside the enclosure, heat and noise may be higher.

As a result of overclocking experiments, this video adapter showed the best GPU potential among all previously tested Radeon RX 570/580. Some gaming tests were able to pass at frequencies up to 1470 MHz. However, the stable “ceiling” turned out to be lower, we settled on the value of 1450 MHz. From memory they reached 2015 (8060) MHz, higher frequencies led to artifacts and a drop in stability.

Overclocking to frequencies of 1450/8060 MHz was accompanied by an increase in the power limit. The fan speed was fixed at 2200 RPM, which helped keep core temperatures below 66 ° C, although the noise level was rather high.

Characteristics of the tested video cards

To get an analogue of the older video card Radeon RX 580 with floating frequencies in Boost mode, the core frequency for Sapphire is limited to 1320 MHz. The memory was accelerated to the prescribed 8000 MHz.

The rival will be the Gigabyte GV-N1060WF2OC-6GD video card, one of the simplest non-reference models of this series, more about it will be described in a separate review. In the nominal, Gigabyte’s frequencies were brought to the recommended level, which often meant an average Boost at 1848 MHz or slightly lower.

The table shows the official specifications. The graphs show the full frequency range including peak Boost values.

Testing technique

The tests were carried out in a resolution of 1920 × 1080 at the maximum or close to this level graphics settings.

Assassin’s Creed Origins

For testing, the built-in gaming benchmark was used, which was run several times for each video adapter.

A standard profile of the highest Ultra quality is selected.

Battlefield 1

Selected a new test scene on a large map with difficult terrain. This is the beginning of the second mission of the “Go Savoy!” Story campaign. The same sequence of actions was performed with shooting and throwing grenades. The duration of the test episode is 52 seconds. At least seven repetitions.

Selected Ultra-quality graphics. Tested in DirectX 11 using Fraps and DirectX 12 using Mirillis Action!

Call of Duty: WWII

Performance comparisons were made early in the game. A platoon of soldiers rushes on a landing ship to the coast of Normandy under enemy fire. A simple episode rich in visuals. The duration of the test segment is 110 seconds.

The highest graphics quality and cinematic SMAA T2x anti-aliasing are set.

Divinity: Original Sin 2

An identical sequence of actions was performed for testing, which combines the use of magic and a walk through a detailed village. The procedure is shown below.

Maximum graphics quality selected.

Elex

Testing was done with Fraps at the start of the game after going down the elevator. A walk was performed along a certain route, several repetitions. Abundant vegetation and bright lighting put a lot of stress on this simple test scene.

Maximum graphics quality for all parameters and SMAA anti-aliasing.

Fallout 4

Testing was done with Fraps right after leaving the hideout at the start of the game. We took a short walk through the surroundings with an abundance of vegetation and rich rays of light. Scenes with this environment will cause the most noticeable performance degradations. The procedure is shown below.

The profile of the highest quality graphics is selected, in addition, the shading of HBAO + is used.

Kingdom Come: Deliverance

Testing was done with Fraps at the start of the game. A run from the smithy to the city market was carried out. There are drawdowns in the game with changes in illumination during the transition from an external location to the premises, therefore such a moment is included in the test walk. The entire sequence of actions is reflected in the video clip.

A very high quality profile has been selected. The fps limit was removed via the r_vsync 0 command in the console.

Middle-earth: Shadow of War

For testing, the built-in gaming benchmark was used, which was run 5-6 times on each video card.

The game has extremely high demands on video memory. In order not to initially put our Radeon in a restrained position, the Ultra-quality profile is selected, but the textures are lowered to a high level.

Remothered: Tormented Fathers

A small walk in the courtyard of the mansion at the beginning of the game was repeated. Several repetitions.

The standard Ultra quality profile is selected.

SpellForce 3

Testing was carried out at the location “Gray Citadel”. It is a large detailed level with lots of detail and thick fog at the foot of the cliffs. A walk was performed along a small route relative to the first portal with manual movement of the camera. Additional rotation of the camera around one of the objects was performed.

Test results

Assassin’s Creed Origins

The best results in Assassin’s Creed Origins are shown by the GeForce GTX 1060, and the Radeon RX 580 is inferior to about 10%. Overclocking allows you to catch up with the competitor. The load of video memory is approaching 4 GB.

Read more about in-game performance in the dedicated benchmark.

Battlefield 1

Radeon RX 580 is faster than the competitor in any DirectX version. At the same time, the transition from DirectX 11 to DirectX 12 provides a slight drop in fps for all participants. Sapphire Nitro + at the initial frequencies does not differ much from the Radeon RX 580 with standard frequencies, the gain from overclocking is about 5%. Load video memory up to 3 GB in DirectX 11, and up to 3.2 GB in DirectX 12.

Call of Duty: WWII

AMD representatives are faster than the GeForce GTX 1060 in the new Call of Duty, albeit with a minimal difference. The advantage of Sapphire Nitro + over a regular video card is about 2%, an increase from overclocking to 6%. As for the load of video memory, the game can load the entire available volume, even on models with 8 GB, but this factor has little effect on performance.

Divinity: Original Sin 2

In Original Sin 2, the first place belongs to the GeForce GTX 1060. The Sapphire video adapter shows the same performance at maximum frequencies. At par, it is 3% faster than the regular Radeon RX 580.

Read more about in-game performance in the dedicated benchmark.

Elex

After a number of updates, the game has slightly changed visually, the overall color scheme has changed, the depth of field effect is less involved, and more rain. As a result, the results obtained may differ from those that were in the first testing in this game. Sapphire and GeForce GTX 1060 have very similar performance, the regular Radeon RX 580 is slightly weaker. In overclocking, the lag behind NVIDIA’s rival is more obvious. The load of video memory in the test scene is 3.1 GB.

Fallout 4

After adding HD textures in Fallout 4, we got unstable results for a long time on AMD solutions, but finally the performance on Radeon stabilized, and the minimum fps increased. This is a good reason to re-compare.

Now the difference between the Radeon RX 580 and the GeForce GTX 1060 is minimal, and Sapphire is quite comparable to its rival. In overclocking, the GeForce GTX 1060 already has a clear advantage.

Kingdom Come: Deliverance

In this new game, the Radeon RX 580 leads, beating the GeForce GTX 1060 by 9-13%. Sapphire is another 3% faster, overclocking provides about the same acceleration. During the test walk, 2 GB of video memory was loaded.

Middle-earth: Shadow of War

Ultra textures hit the performance of the 4GB Radeon RX 580 critically, as seen in our dedicated testing. The combination of the maximum graphics settings with the usual high quality textures is much easier – the lag behind the GeForce GTX 1060 is only a few percent. Sapphire’s results are almost indistinguishable from the standard version of the Radeon RX 580. Increase from overclocking to 6%.

Remothered: Tormented Fathers

A colossal gap between the participants. The GeForce GTX 1060 has a significant lead over the competitor. There is no optimization for Radeon RX here at all. The download of video memory barely exceeds 2 GB.

SpellForce 3

The most beautiful strategy game of the past year. And the best performance is demonstrated by the GeForce GTX 1060, overtaking the Radeon RX 580 by 7-12%. Sapphire wins a couple of percent over its brother and reacts extremely poorly to additional overclocking. The game uses 4 GB of video memory in the test scene.

Subnautica

Nice open world survival game with moderate system requirements. All participants showed high fps, but AMD representatives lost a little to the GeForce GTX 1060. The difference between the two Radeon RX 580s is minimal, the acceleration from overclocking is at the usual level of 5-6%.

The Evil Within 2

The results are higher than in our first tests, but this is true for both competitors. Radeon RX 580 is 4-9% faster than GeForce GTX 1060, with less advantage in overclocking.

Wolfenstein II: The New Colossus

In Wolfenstein 2, the Radeon RX 580 is confidently leading, but a serious advantage in terms of average fps is combined with a lag in terms of the minimum indicator. It should be noted that these figures are slightly higher than those that we received earlier, probably thanks to the new driver. As a result, both video adapters allow you to play with complete comfort at high frame rates. With the selected settings in the test shootout, the memory load is about 3.8 GB.

Read more about in-game performance in the dedicated benchmark.

3DMark Time Spy

Radeon RX 580 outperforms GeForce GTX 1060 by 1.5%. Sapphire is an additional 2.7% faster, and overclocking delivers a 5% boost.

conclusions

Let’s summarize first. There are modern games that easily use more than 4GB of video memory, but in this comparison we tried to compensate for this. For example, Middle-earth: Shadow of War uses regular textures. So the results obtained allow us to make a general comparison of the Radeon RX 580 and GeForce GTX 1060 without regard to memory or with minimal consideration of this factor. The Radeon RX 580 wins in six out of 14 applications and often lags slightly behind in other games. In overclocking, the GeForce GTX 1060 slightly strengthens its position, but this is a particular situation – we must take into account the specifics of the compared samples and a slight overclocking of memory in our Radeon.

The Sapphire Nitro + Radeon RX 580 4GB video card, in addition to the reduced memory size, also offers an unusual combination of frequencies. The factory overclocked core is combined with the reduced frequency of the GDDR5 memory modules. However, at 1400/7000 MHz, the card is a couple of percent faster than the regular version with 1340/8000 MHz frequencies. Another thing is that the potential of the memory microcircuits themselves is not high, and it is possible to overclock them just up to the prescribed 8000 MHz. Limited memory overclocking can be a limiting factor if you want to squeeze the maximum performance out of the Sapphire Nitro +. A significant advantage of the video card is powerful cooling and a high-quality printed circuit board with enhanced power supply. It is worth noting the careful approach to VRM cooling, where even the backplate is used as an additional heatsink. In general, this is an excellent video card with one drawback – lower memory frequency. Moreover, the latter is easily compensated by overclocking. Also, a video card with such memory characteristics loses its attractiveness for miners, which in theory should make it more affordable for an ordinary buyer. In reality, alas, these Sapphires are also being bought up.
