Radeon RX 480 8gb Hashrate – Mining Cryptocurrency

Before we proceed to testing, it should be noted that there are two variants of the Radeon RX 480 card (hashrate), one with 4GB of video memory, which works with a clock frequency of 7 Ghz, and it is sold at a lower price, and the more expensive 8GB model, memory in which it operates at 8 GHz.

We tested the ASUS Radeon RX 480 card with 8GB and 8 GHz video memory, so the article presents the results of mining Ethereum on this map. A model with 4GB of memory and 7 GHz video memory frequency will mine more slowly by about 2-3 Mhs compared to the 8GB 8 GHz version, so if you buy equipment for ethereum mining, pay attention to the models with 8 GB of memory.

Hashrate RX 480 8GB

We used the Claymore Dual Miner program, running it with the default settings: 1266 MHz frequency of the graphics processor of the video card and 8 GHz frequency of the video memory. The result we got was approximate 24.7-24.8 MHS with power consumption in terms of the 108 watts program, and real power consumption 177 watts. Taking into account the efficiency of 80 Plus Gold PSU, we can say that the card’s power is 150 watts at default settings. The numbers are also confirmed by the fact that during the mining of Ethereum with the settings of the frequency of the graphics processor, the default frequency is about 1240 MHz, never reaching the maximum 1266 MHz.

In fact, reaching the power limit of 150 watts for which the card is designed, a slight excess of this limit (by a few percent) allows to achieve full overclocking of the graphics processor to a full 1266 MHz … What is not important for Ethereum mining, but may be important for other crypto algorithms, not so sensitive to video memory.

In the double mining mode, you can simultaneously mine Ethereum and Decred at the same time, and the results will be approximately 24.3 MHS for Ethereum and about 365 MHS for Decred (with an intensity of 30 by default). Later, we increased the intensity for Decred to 35, which led to a drop in Ethereum hashing power to about 24 MHS and increased the hashing power during Decred mining to about 450 MHS. So we made sure that the RX 480 works fine in the dual-mining mode and with a slight drop in the hashing power for Ethereum, the power of the Decred mining increases significantly.

Dual mining Ethereum and Decred

We proceeded to overclock the card, and the only thing we managed to do was to increase the working frequency of the video memory to the maximum, which in our case was 9 GHz (the card could produce a frequency more, but the overclocking software or the driver have limitations, and 9 GHz is the maximum). With video memory running at 9 Ghz, the RX 480 card gives about 28 MHS of hashing power for Ethereum mining.

It is possible that the hashing power may be even higher if we manage to overcome the 9 GHz limit for video memory. However, at the moment neither AMD’s WattMan program, nor Asus tools allow us to do this. With overclocking, the power consumption increases by about 7-8 watts, but such overclocking is definitely worth doing when mining Ethereum.

Overclocking the RX 480 in MSI Afterburner

We were a little disappointed by the lack of overclocking of the GPU, which has a voltage margin to reach 1340 MHz. Of course, such overclocking does not matter for Ethereum mining , and in fact, if you want to mine only Ethereum, the clock frequency of the graphics processor should be even slightly reduced. Also, we were not too happy with the way the cooling and heat removal from the RX 480 was built here. AMD set the fan rotation speed so that the map remained quiet and very hot, which is not quite suitable for mining.

It seemed to us that the best solution would be to set the fan blade speed to 80%, which would give us moderate temperatures and a not too noisy map. A good choice if mining noise is a problem for you. By setting the fan blade speed to 80%, you can expect about 72 degrees Celsius on the GPU, which is not very good if your mining will be around the clock. Increasing the fan load to 100% significantly increases the noise level, and reduces the temperature on the processor to 68 degrees Celsius, that is, not mu
