Crypto Mining With Sapphire NITRO+ Radeon RX 580 Limited Edition

24 Apr
2017

As promised last week after the official announcement we are starting a series of reviews of the new AMD Radeon RX 5×0 series of GPUs and the first card to go through is the Sapphire NITRO+ Radeon RX 580 Limited Edition. This is one of the top models of RX 580 from Sapphire that comes with higher factory clocks compared to most other RX 580 GPUs and some nice additional extras such as spare fans. Compared to the last year’s Sapphire RX 480 NITRO+ the new RX 580 counterparts do come with higher clocks and improved cooling solution… and a bit higher price as well. The new RX 580 cards that are more like the last year’s RX 480 from Sapphire are now called PULSE and not NITRO and hopefully we are going to soon have a PULSE card to check out, but for now let us see what the NITRO+ Radeon RX 580 Limited Edition has to offer…

SAPPHIRE NITRO+ Radeon RX 580 8 GB Limited Edition:
– 2304 stream Processors
– 14 nm FinFET, 4th generation Graphics Core Next (GCN)
– 1450 MHz GPU Boost Clock
– 8192 MB GDDR5 Memory, 256 bit Memory Bus, 2000 MHz Memory Clock
– Display Outputs: 1x DL-DVI-D, 2x HDMI 2.0b, 2x DisplayPort 1.4
– All-new Dual-X 95 mm fans, two ball bearing
– Power connectors: 1x 6-pin PCI-E, 1x 8-pin PCI-E
– Power consumption: 225W
– Dual UEFI BIOS

The new larger cooler is a welcome improvement as are the the additional spare fans included in the package of the RX 580 NITRO+ LE GPUs, though the non Limited Edition RX 580 and the RX 570 NITRO+ also come with the same new cooler. Other notable difference however is the additional power connector found on the NITRO+ RX 5×0 series, they all feature a single 6-pin and a single 8-pin PCI-E power connectors. The extra power connector is needed due to the higher clocks and increased power consumption, however it can be a problem for miners willing to connect 6 of these cards with a single power supply. So do have that in mind as well as the fact that the PULSE series are with a single and not dual PCI-E power connectors.

Here is how things look according to GPU-Z for the GPU specs. The GPU clock is running perfectly fine at 1450 MHz and allows for some extra overclock to about 1500 MHz, though not much higher than that. The higher GPU clock comes with increased operating voltage of about 1.1750V and that also results in increased power usage, up to over 140W GPU only Power Draw according to GPU-Z. The video memory is running at 2000 MHz and we kind of expected to see Samsung GDDR5 memory used here, after all this is a more expensive top model from Sapphire of the new RX 580 and is also a Limited Edition one. Unfortunately Sapphire has opted to go for Hynix memory for this series and as a result you can expect not the best performance in memory intensive mining algorithms such as Ethash used by Ethereum or Equihash used by Zcash.

Now off to the benchmarks with some popular algorithms used by the most profitable to mine crypto currencies at the moment. Starting with Ethereum (ETH) mining using the latest Claymore Dual ETH miner version 9.2 and we are getting just about 22.5 MHS from the Sapphire NITRO+ Radeon RX 580 Limited Edition. This is with the stock settings, no memory modifications and is definitely a disappointing result, though considering that the memory used was Hynix at 2000 MHz it seems that the default memory timings are pretty relaxed in order to keep the hgiher operating frequency. Again going for Samsung memory on this Limited Edition model is a must do thing in our opinion, so we are wondering why Sapphire didn’t do just that…

We can see similar not so great result for mining ZEC using the latest Claymore ZCash AMD GPU Miner 12.4, but this is to be expected since the Equihash algorithm is also more memory intensive. The average hashrate we are getting for ZCash (ZEC) mining with this video card is about 296 H/s. The reason for the lower hashrate than what we have seen from some lower clocked RX 480 GPUs is again most likely the Hynix memory, but also the new driver that AMD has released with support for the RX 500 series might be responsible for the not so good mining hashrates and the official AMD Radeon Crimson ReLive Edition 17.4.3 driver for the RX 500 series is a WHQL one and may not be the best performing one for crypto currency mining.

Some more benchmark results at stock settings:
– Decred (DCR): 1.220 GHS
– CryptoNight (XMR): 600 H/s
– LBRY (LBC): 0.165 GHS
– Pascal (PASC): 0.830 GHS
– X11Ghost (SIB): 8.2 MHS

As far as optimizations go, you can play around with the memory straps and get better results. Furthermore reducing the GPU frequency from the default high value will also allow you to lower the voltage and achieve significantly lower power usage, especially if optimizing for ETH, though ZEC should also be fine with a bit higher voltage. Some people also report that the RX 580 LE card can run just fine on a single 8-pin PCI-E power, though should you try that make sure you have optimized the frequency and voltages of the GPU first in order to avoid overloading the power line…

As a conclusion we can say that the Sapphire NITRO+ Radeon RX 580 Limited Edition video cards although seemingly attractive for miners have been clearly designed for gamers and they will do pretty good for gaming with the higher operating clocks. Miners may also like the larger cooler and the extra fans in the package, but the two power connectors and the increased power usage is not something that is so great. At stock settings the RX 580 LE is a bit disappointing in terms of performance, though with some tweaking you can probably get better performance and low power usage. Then again you should be able to achieve the same result with a cheaper RX 580 or even RX 570 after you tweak the memory straps, reduce the clock speeds and operating voltages. So out of the box this is good for gamers, with some tweaking it can still become a miner friendly video card, though you should be careful what you do but the higher price of this particular model may make it not as attractive for miners as for example the GPUs from Sapphire’s PULSE series.

How many watts of power it uses to give full 100% performance? When on stock settings.

Seen your last post about the release of the 580 and bought one. Should be arriving in a few days, and after you new post i’m glad i bought one.

Kinda disappointed with the watts to performance ratio rx 470- 26-28 mhs at 90-120 watts where u guys said 225w at 23 mhs for the rx 580 guess I’m staying with the 470 until something better comes out for power to watt ratio

Thanks for sharing valuable information, please advise did you find out if Pulse series is better than Sapphire NITRO+ Radeon RX 580 Limited Edition?

Also is it true what Dayton says that

Hi , what is the best bios mod for this Sapphire NITRO+ Radeon RX 580 Limited Edition 8GB (HYNIX). I need some help as this card is only 21-22 MH/s on eth.

can you give me the hardware details,?
i planning to build one
thanks

how to power up 6 of these ? do i need 2nd power supply they comes with 14 pins ?

@Max
You should flash your card with this bios:
http://www.mediafire.com/file/wf4exl9xgtc83uy/moddedv2.rom

I had 8 cards running on my rig for weeks and it has been pretty stable so far.

# 29.8MH/s on ETH
globalcore 1350
globalmem 2250
globalpowertune 5

or

# 30.10Mh/s on ETH
globalcore 1390
globalmem 2280
globalpowertune 5

NB.: globalpowertune should be between 4 and 7 for this card.

@Dayton
You are right, this card is expensive out of the box, but did you can try to tune it to consume less.

@Tuitan Wilde

1 1300W (EVGA) if you only have 6 cards and a SSD
or
x2 750W (EVGA) if you are planing to add 2 more cards to your rig ;)

If you have found this usefull, feel free to drop some ETH here -> 0x0c85ff12035e297cad0788b07b3782a505637206
