VertCoin (VTC) Mining on Old AMD Radeon R9 280X GPUs is Profitable

8, Feb 2021

We are back to VertCoin (VTC) mining using the new VertHash algorithm, but this time we are going old-school to AMD Radeon R9 280X and the performance these old, but gold video cards from the earlier days of crypto mining can deliver mining VTC at the moment. We have already tested mining VertCoin (VTC) on AMD Radeon 400/500 series of 4GB GPUs and the results were pretty good, but it seems that the R9 280X are still too early to retire even though they have been announced more than 7 years ago back in 2013. Hell, even going further back to the Radeon HD 7970 GPUs that were used for Bitcoin mining back in the early days of crypto we can get pretty much the same results as with the “newer” AMD Radeon R9 280X, so dig these up as well if you still have them around somewhere.

The VertHash algorithm is a memory-intensive one with a minimum requirement of 2GB of video memory, so even older video cards with 2GB or 3GB can be used for mining VertCoin (VTC) after its recent fork from the previous LyraRev3 algorithm. Mining with VerthashMiner on AMD Radeon RX 570 4GB GPU at stock settings gives around 350 KH/s and with modified video BIOS with optimized memory timings the hashrate goes to about 450 KH/s. The old AMD Radeon R9 280X with 3GB VRAM can manage around 360-370 KH/s mining VTC at the stock settings of 925 MHz for the GPU and 1375 MHz for the video memory, but overclocking it to 1050 MHz for the GPU and 1500 MHz for the video memory can easily get you around 400 KH/s mining hashrate. Checking the profitability of a 6x Radeon R9 280X GPUs in a mining rig, and after paying for electricity, can currently earn around $5-6 USD per day (depending on electricity costs).

Gigabyte AORUS GeForce RTX 3060 Ti MASTER for Mining Ethereum

7, Feb 2021

One of the most popular NVidia RTX 30 series of GPUS for mining crypto and more specifically for mining Ethereum (ETH) lately has been the RTX 3060 Ti, so no wonder these are hard to find as they are generally cheaper than RTX 3070, but have the same memory and performance for Ethash as the 70s. We’ve managed to get our hands on one Gigabyte AORUS GeForce RTX 3060 Ti MASTER (GV-N306TAORUS M-8GD) video card in order to play around with and share some interesting information, mining settings and performance results with anyone that might be interested.

The AORUS GeForce RTX 3060 Ti MASTER model from Gigabyte comes with a really huge cooler that has three fans with interesting overlapping design, plus it offers six video output connectors and one interesting feature – a user controllable LCD display on the side of the card. And as already mentioned, thanks to the 8GB GDDR6 memory with a 256-bit wide bus this RTX 3060 Ti should also be capable of delivering about 60 MH/s hashrate for mining Ethereum (ETH). The RTX 3060 Ti however has a more stripped-down graphics processor compared to the RTX 3070. While that shouldn’t be much of a problem for Ethereum mining, the video card however will be slower in more GPU-intensive algorithms compared to RTX 3070!

The user programmable LCD display on the side of the video card is controlled through Gigabyte’s RGBFusion 2.0 software that is also used for the addressable RGB operation for the motherboard RGB and fans connected to it. The software allows you to use the display to show things such as GPU Temp, GPU Usage, GPU Clock, Fan Speed, VRAM USAGE, VRAM CLOCK, TGP, FRAME-RATE and you can also put a custom image or animated GIF file to be shown on the display and some more. For a mining rig having a display that shows individual operational GPU temperature or FAN speed could be quite nice if you have the functionality already on the video card, no wonder the first thing with did with the LCD display was to set it to show the temperature of the GPU.

What about mining hashrate for this Gigabyte AORUS GeForce RTX 3060 Ti MASTER 8G video card? This particular model is with 240W TDP by default (the 100% setting in MSI Afterburner) and you can go down as low as 100W and as high as 270W (-58% to +13%) and it is also clocked higher. As a comparison the reference design RTX 3060 Ti from Nvidia has just 200W TDP, so 20% higher power usage by default for this Gigabyte card and we don’t need the extra power usage for ETH mining. Anyway, the out of the box performance this video card is delivering is around 51 MHS at stock settings, but why settle for it when you can easily push it to 60 MHS and even reduce the power consumption as we have already seen playing around with Palit GeForce RTX 3070 GameRock GPUs for mining Ethereum.

Starting to optimize settings for better performance and higher hashrate for Ethereum mining on the RTX 3060 Ti we went down to 60% TDP with reduced GPU clock (-500 MHz) and increased memory clock (+1150 MHz) in order to get the expected 60 MHS hashrate. With Palit’s RTX 3070s we’ve seen similar settings, though there the TDP was lower at 50% TDP for the same 60 MHS performance. Do note that we needed +1150 MHz for the video memory here, even though out sweet spot of 1100 MHz will do just fine for 60 MHS when using a mining rig as the test setup was with a single card and the display connected to it – this means higher power load and a bit of a performance drop. So, in a 6x GPU mining rig running the memory with +1100 MHz you should still be able to get 60 MH/s Ethash mining hashrate.

Here we tested with fans running at 100% due to the small mini-ITX case the GPU was running in and the not so good airflow, though you should easily be able to run the cooling fans lower with the GPU in a mining rig with good airflow and still get things running cool. The massive cooler and the three fans do great job in keeping everything cool, especially with the optimized settings for mining that put the power usage of the GPU down to just about 140W as reported by the miner compared to the stock TDP of 240W.

The Upcoming Ethereum ASIC Miners To Offer 2000+ MHS

3, Feb 2021

There is a lot of talk going on around the new generation of Ethash ASIC miners for mining Ethereum (ETH) that are expected to be released for order in the following few months, although nothing is official or really 100% confirmed, but both devices are expected to have hashrate higher than 2000 MH/s. We are talking about the Innosilicon’s A11 ETH miner and an upcoming device from a newcomer on the mining market, a company called Linzhi that has been getting some attention for a while now. Linzhi Inc was founded by Chen Min, the former CTO of Canaan, a popular name for everyone that has been into crypto mining for a while already as this is one of the first companies to be making Bitcoin ASIC miners – the Avalon miners.

Currently the Innosilicon A10 Pro ETH Miner is the best performing specialized non-GPU-based miner for Ethash with 500 MHS hashrate and 950W of power consumption and a price of $4388 USD　(or 0.125933 BTC) as per the official company website (currently all sold out). The alternative is using GPUs for mining ETH and you even might be able to get the same level of performance as the A10 Pro ETH Miner if you go for Nvidia GeForce RTX 3000 series – 8x RTX 3060 Ti or RTX 3070 or 5-6x RTX 3080 or 4-5x RTX 3090 video cards, but unfortunately pretty much all GPUs suitable for mining are currently hard to find and more expensive than usual.

F2Pool did an unboxing and a test of a sample Linzhi Phoenix ETH miner (the video above). The device is supposedly capable of 2600 MHS hashrate for Ethash with a power usage of 3000-3500W. The Linzhi Phoenix E2600M ETH mining devices are supposedly to be up for purchase around March-April this year with a price in the range of 13-15 thousand USD. The main problem with the Linzhi miner is that it has 4.4GB of memory and Ethereum’s DAG file is already over 4GB in size, meaning that the life expectancy of these miners for mining ETH won’t be very long. If they start shipping as announced and you are among the first to get the device you may still end up with just 4-5 months of use for mining Ethereum, though you would still be able to mine other crypto coins with the Ethash algorithm and smaller DAGs. So, maybe everything was great when they started development 2 years ago, but now 4.4 GB is not enough and if they do not manage to increase the available memory by the time of release to the market things might not be looking very good for their sales.

The Innosilicon A11 ETH miner is the other upcoming next-gen ETH ASIC miner. Supposedly the A11 Ethash miner will be delivering 2100 MH/s Ethash hashrate with just 2300W of power usage and should come with 8GB memory. The not so good thing here is that the price will be higher, probably in the range of about 15-16 thousand USD with shipping expected to start somewhere in April-June time. The Innosilicon is probably the better choice if the final end-product specifications turn out to be as the values we are expecting, as even though it may be slower in terms of hashrate, and more expensive as a price, but is also more power efficient and better equipped for long term use with enough onboard memory.

You should also consider the fact that Ethereum (ETH) will be switching from PoW (Proof of Work) to PoS (Proof of Staking) or with other words moving from mining to staking as a model of generating new coins. This transition has already been started, even though mining is still active and will be for maybe 2 years at least, but when looking for a long-term investment in mining hardware you should have things like that in mind. Not to mention that unlike the specialized ETH miners, going for GPUs allows for much better flexibility even though they may not be as efficient in terms of performance for a specific algorithm.
