My first test with the cards they were just sitting in the motherboard with gravity! The next thing I noted is that they are passively cooled, so no fans on the GPU, just a heat sink. This isn't a problem in our rigs as they are basically a wind tunnel and keep everything nice and cool. I tried to install 8 of these cards, to give 16 GPUs total. Unfortunately the 8 slot motherboard could not handle this and would not boot with all 8 cards installed.
One type of board supported only 5 cards, and another type of board supported 6 cards. So 12 GPUs was the most I could operate 6 x 2. I'm now going to investigate if there is an 8 slot motherboard out there that can support 8 cards, giving 16 GPUs. Testing these cards with HiveOS yielded pleasant results. Each single card was recognised as two individual GPUs. That's right. This means that you get twice the mining performance with the single board when compared to a standard RX 8GB graphics card.
The normal overclocking methods didn't seem to apply. What I did was flash the bioses, all 12 of them, and apply the one click timing patch in polaris bios editor. Then simply set the memory overlock to This yielded the most stable results after a couple of hours of messing around. There may be better solutions but I was fairly happy with the numbers at this overlock. Mining Ethereum achieves about Topics Graphics. See all comments Biostar says that it can deliver iMiner systems in "large quantities.
Remember a few years back after the crypto market crashed the last time, and RX s were discounted well below MSRP and bundled with popular new game releases as companies tried to get rid of their glut of inventory? Biostar must have found a bunch of leftovers in a warehouse and are trying to get rid of them before that happens again.
It doesn't really seem like a particularly good time to be investing in mining equipment built around nearly 6 year old graphics technology. Biostar has never been shy to sell mining hardware openly. They done it before, and they are obviously doing it again. While people may be upset with them, the truth is that the other AIB partners are probably doing the same.
They just do it on the sly. Also what is a kW usage? The RX and definitely missed their time to shine in the gaming scene, they were always more popular as mining cards. It's also kind of insane that 6 years after Polaris's launch, its still being produced new, and if you can actually find one for gaming, it still puts up a fight in the intro P gaming market.

In general, 4GB is sufficient for even the most demanding hashing algorithms and you will not see any performance gains just by having more memory. This is where the speed and quality of the memory comes into play. The 8GB RX has a higher memory clock speed which gives it a slight edge while running memory intensive algorithms such as Ethash used by Ethereum.
However, hashing speed also depends on the quality of the GDDR5 memory. They are also easier to overclock. To mine you need DAG file to be loaded into card's memory. DAG file grows in time. So when and if it will superpass 4GB - you could mine no more with these cards. Sign up to join this community. The best answers are voted up and rise to the top.
