The AMD Radeon HD 8570 graphics card (also known as AMD R7 240/340 and Radeon 520 OEM) was widely used by PC OEMs a few years ago. This is a video adapter that is not designed to perform complex computing tasks, but still has little potential for such work.

The AMD Radeon R7 240 (HD 8570) video card is based on the GCN1 architecture with the Oland core:

The AMD Radeon HD 8570 graphics card (aka AMD R7 240/340 and Radeon 520 OEM) has a very simple power system that uses the potential of the PCI-E slot to provide a TDP of 50 watts.

The video processor is powered by two phases, consisting of two n-channel MOSFET transistors MDU1517 (30V, 100A) plus two MDU1514 (30V, 66.3A) with a 7210A PWM controller from Gsteck. Nearby is the APW 7153B controller:

The memory is powered by single phase MOSFET transistors MDU1517 and MDU1514:

The computing capabilities of the video card are due to the Oland video processor (215-0837015):

2 Gb AMD R7 240 memory is equipped with 8 Samsung K4W2G1646E-BC11 GDDR3 memory chips (4 on each side of the PCB)

On the reverse side of the board there are 4 memory modules and a number of elements of the power system, including the 78M05 stabilizer, the GS7256 converter (8-pin element at the bottom left):

How to Tune or Boost: AMD Radeon HD8570 Computing Performance

The AMD Radeon HD 8570 graphics adapter is equipped with GDDR3-type video memory, so you can’t count on high performance on memory-intensive algorithms.

The frequency of the video processor for video cards R7 200 (R7 300) is rather weak, on the Radeon HD 8570 it is only 780 MHz with 384 shaders:

To maximize the use of the computing resources of the video card, it is better to use an operating system with a Linux kernel. For multi-threaded computations, OpenCL version 1.2 is available:

When manually setting up miners for AMD R7 240 (340) video cards, you need to use the worksize 256 parameter:

The AMD Radeon HD 8570 graphics card has the following specifications (compared to the Nvidia GT1030, AMD Radeon RX550 and HD 7750 graphics cards):.

The clinfo program in xubuntu detects the video card as a Device with AMD AMD Radeon HD 8500 topology.

Teams

lspci | grep -E "VGA|3D"

as well as

sudo lspci -v -s 01:00.0

executed in Linux give information that this is a VGA controller manufactured by Advanced Micro Devices, Inc. [AMD/ATI] Holland [Radeon HD 8570 / R7 240/340 / Radeon 520 OEM].

The amdcovc program also detects the adapter as Oland Radeon HD 8570 / R7 240/340 / Radeon 520 OEM, while the core frequencies, memory frequencies are not visible, temperature and fan speed information is available.

Memory chips cannot be viewed by the amdmeminfo utility in xubuntu 20.04 due to a segmentation error.

Due to the low performance of the memory subsystem typed with GDDR3 memory chips, mining on algorithms like Ethash on an AMD Radeon HD 8570 video card does not make much sense. At the same time, due to the presence of 2 GB VRAM, a fairly large number of mining algorithms can be run on the video card and at the same time get a decent hash rate for such a weak card on algorithms like Verthash and the Cryptonight family.

How to Maximize: AMD R7 250X hashrate when mining

To test the capabilities of the AMD Radeon HD 8570 video accelerator, xubuntu 20.04 and Windows 8.1 operating systems were used.

The choice of the latest LTS version of xubuntu is due to the fact that modern miners are usually compiled for the latest versions of Linux kernels, so they may not work on releases 16.04 and 18.04. Compiling them yourself is not possible, since their source code is closed. There are no problems with miners that can be built from open source, for example, xmrig.

Given the weak memory performance, the Radeon HD 8570 graphics card can be used on algorithms that load the kernel, such as verthash, Cryptonight varieties and others.

An example of a script for running the xmrig program for mining on a Radeon HD8570 video card (you must enable the GPU_FORCE_64BIT_PTR=1 parameter, otherwise mining will not start due to lack of memory):

#!/bin/sh

export GPU_FORCE_64BIT_PTR=1

export GPU_MAX_HEAP_SIZE=100

export GPU_USE_SYNC_OBJECTS=1

export GPU_MAX_ALLOC_PERCENT=100

 export GPU_SINGLE_ALLOC_PERCENT=100

sudo ./xmrig -a cn/gpu -o stratum+tcp://cryptonight_gpu.eu.mine.zergpool.com:4445 -u кошелек -p c=BTC,имя_компьютера,refcode=81de238596774683dd427a9d57bae6af -k --donate-level=0 --asm=auto --cpu-priority 0 --keepalive --opencl-devices=1 --no-cpu

sleep 10

In xubuntu 20.04 in the VerthashMiner 0.7.2 miner, the AMD Radeon HD 8570 video card shows a hashrate of about 70-72 kH / s, which is more than the level of many processors that consume the same amount of energy:

In Windows 8.1, the hash rate on the verthash algorithm for the Radeon HD 8570 video card is 50 h/s:

Given the memory bandwidth of 28.8 GB / s, you should not count on a decent result when mining on ethash – the hashrate on this algorithm for the 8570 is 3-4 mh / s.

Mining on the Ethash algorithm (DBIX coin) on an AMD Radeon HD 8570 video card in the PhoenixMiner 5.5C program:

On the zelhash algorithm (Equihash 144.5), the AMD Radeon R7 200 in the lolminer 1.21 program has a hash rate of sol / s units:

Miners Sgminer-fancyIX 0.7.3, srbminer-multi, wildrig, teamredminer, gminer – modern versions do not work on the AMD Radeon HD 8570 video card.

Information on the hashrate of the AMD Radeon HD 8570 video card on some PoW mining algorithms:

  • Argon2-dyn – 8-9 kh / s (sgminer-dyn-1.0.0-windows-x64);
  • Ethash (for DAG up to 2 GB) – 3.3-3.5 mh/s (PhoenixMiner 5.5C), DBIX mining;
  • Verthash – 70-72 kh/s in xubuntu 20.04, in Windows 8.1 the hash rate is 10-20 kh/s lower;
  • Cryptonight_Haven — 98-100 h/s (xmrig 6.11.2);
  • Cryptonight_GPU – in xmrig 5.11.4 does not start, complaining about lack of memory;
  • Cryptonight_R — 75-90 h/s (xmrig 6.11.2);
  • Equihash — 29-30 sol/s (Claymore ZCash Miner 12.6);
  • Equihash 144,5 — — 2.5-3 sol/s (lolminer 1.26);
  • Scrypt – 85-90 kh/s.

Conclusion

The AMD Radeon HD 8570 video card is not very suitable for cryptocurrency mining, but still has a certain computing potential sufficient for mining VTC coins on the verthash algorithm, where it has a performance greater than that of 4-6 core processors, as well as for mining on Cryptonight algorithm varieties .

You should not count on a large income from mining on AMD R7 240 and 340 video cards, although, if you wish, you can still earn a small amount of cryptocoins and experience on them.
