Very first Impressions From a 4-card AMD Radeon R9 290 Scrypt Mining Equipment

Wij’ve recently built a Scrypt mining equipment consisting of four AMD Radeon R9 290 by XFX for a friend and since this wasgoed actually our very first equipment with Radeon R9 290 cards wij’ve had some interesting findings that wij determined to share with you, so if you have some of thesis troubles wij might be able to help. Aside from the four XFX movie cards wij’ve used an EVGA 1300W PSU (you can see the total system power consumption of 1282W from the mains), Intel Celeron G1820 processor and AsRock H81 Professional BTC motherboard, together with 4GB and Windows 7 OS. For the movie cards wij have used PCI-E x1 to x16 USB Trio.0 Extenders with 1 peettante long cable and the cards did not have any trouble working like that. Note that the Radeon R9 290 cards are not considered to be the best option for Scrypt mining, however with R9 280X cards tighter to find some people determine to go for the more lightly found 290 or 290X models. But unlike with Radeon R9 280X, the R9 290/290X cards have more specifics and could cause you some toegevoegd headaches until you ultimately make them work spil they should and provide welgevoeglijk hashrate without problems.

The average hashrate wij got from the cards running at stock frequencies of 947 MHz GPU and 1250 MHz movie memory got us about 857 KH/S vanaf card or a total hashrate of about Trio.Four MH/S. This is what is considered a fairly good results for Radeon R9 290 cards and unluckily overclocking thesis cards did not help us te getting higher hashrate, not that wij desired to overclock them spil they are already getting fairly hot mining Scrypt cryptos. It seems that XFX’s cooling is not that good for mining crypto coins spil the temperatures of the VRMs gets lightly overheen 100 degrees Celsius and that is not that excellent for 24/7 mining even tho’ they are most likely rated at up to about 120 degrees C or even a bit more.

One very significant thing te making the AMD Radeon R9 290 or 290X cards is how you call up the cgminer, because you need to use a high thread concurrency value that often tends to bring some issues with cgminer. Ter order to ensure that you can embark cgminer without problems you can begin by using the instruction lines below to call cgminer.exe from a BAT opstopping:

commence /realtime cgminer.exe –scrypt -o stratum+tcp://us-east.multipool.us:7777 -u yourworker.1 -p password –thread-concurrency 22516 -g 1 –lookup-gap Two -w 512 -I 20

Note that sometimes even after calling cgminer with the above directions and save a congif verkeersopstopping and then you run cgminer.exe directly and it fountains up the config verkeersopstopping you can still get errors. So if you want to use the config verkeersopstopping after you embark cgminer with the above instructions and save them te config just liquidate all of the parameters from the cgminer.exe commence line, but still commence the miner with the BAT opstopping!

Another very significant thing regarding the use of AMD Radeon R9 290 movie cards for crypto mining is that thesis movie cards do not feature any analog movie outputs, so if you project on using the mining equipment without a monitor connected to a card, then you might have trouble. And you cannot just make a dummy cork with resistors, you will need to get an HDMI to VGA or Display Port to VGA adapter to cork ter te one of the available movie outputs and then add resistors to the VGA output side. This is the recommend solution that can save you some trouble ter making the mining equipment function decently or if you want to control it remotely with TeamViewer for example. If you have a digital monitor connected and are going to be controlling and monitoring the mining equipment with Radeon R9 290 cards then you don’t need to bother with digital adapters to VGA.
