Title: Mining rig info and recommendation Post by: crazyivan on March 01, 2017, 06:19:45 AM Hey guys,
been out of mining for a long time, used to have 7 rigs in period when LTC was skyrocketing. Anyway, thinking of building a small hobby rig, miss that buzz sound of GPU fans. What do you recommend, what card and model and what do you get from it. Was thinking 470 8 MB, is that the best bang for my buck ATM? Thx a lot Title: Re: Mining rig info and recommendation Post by: groovy1962 on March 01, 2017, 06:32:39 AM I think over the next 3 months we're going to have a cycle of new cards, and prices will shift.
For instance the 1080Ti just got introduced and the 1080 dropped in price making the 1070 less competitive. Title: Re: Mining rig info and recommendation Post by: mojoxc on March 01, 2017, 06:49:27 AM Bang for the buck RX 470 or RX 480 depending on what specials are running. The only edge nvidia has is mainly in zcash but the price tag for the 1070 being twice as much doesn't make a lot sense for a large mine.
Title: Re: Mining rig info and recommendation Post by: cparsley on March 01, 2017, 06:51:33 AM is mining still profitable to start here in 2017? Wouldn't think it would, but could be wrong (hence the ask)

Title: Re: Mining rig info and recommendation Post by: RyanLiang on March 01, 2017, 08:22:39 AM RX470 4GB or wait for Vega Vega will be too expensive. RX 480 could be good. Title: Re: Mining rig info and recommendation Post by: crazyivan on March 01, 2017, 10:11:11 AM What do you guys get from 1 480 4 GB or similar card these days? ROI should be about 450 days according to my calculation.

ROI should be about 450 days according to my calculation. The RX480 4GB is really not a lot better than the 470 version when it comes to mining. The two choices most people pick comes down to going with either the RX470 4GB or the RX480 8GB, and the reason has more to do with the RAM speed than either the GPU core or the amount of RAM. Basically the 8 GB RX480's have the highest quality RAM that can be pushed the furthest for overclocking and you can net around 31-33 MH/sec on the Ethash algorithm, which Ethereum and its clones use. For Zcash you can probably get around 330 sols off the RX480 and 300 sols off the RX470. The RX470's usually have slightly lower quality RAM, even with the 8 GB versions, thus why people will just get the 4 GB as you get the cost savings benefit as well. A solid RX470 4GB can yield around 28-30 MH/sec with Ethereum, thus the slight loss of hash is usually more than offset by the lower price. The 470 will also draw slightly less power too, so over a year or two of mining the hash/watt ratio will probably work out similarly. The other big concern is resale value if everything heads south. Gamers will probably prefer the RX480 8GB over the RX470 4 GB, but of course it all depends on how long you mine with them. After a couple of years the resale value on both will probably be similar anyway as they fall out of favor with gamers. A RX470 4GB can be had for around $175 on NewEgg shipped, so ROI using nominal $0.08 cent power and 120 watt load (accounts for pro-rated portion of system draw too based on a 5x GPU rig) would currently be 164 days. Although ETH is trading high right now so this figure will likely be overly optimistic due to either the price falling, network hashrate increasing, or most likely a combination of both. A RX480 8GB can be had for $220, so ROI using the above figures and 130 watt draw would be slightly less at 150 days. Both of these scenarios also assume you are modifying the VBIOS to overclock and under-volt the GPUs to gain the hash-rates and wattage draws listed. Plenty of information on the forum how to achieve these rates, or better so I won't go over that here.

I would also like to add another caveat to the post - Heat/Sound/ease of strapping. The MSI Radeon RX470 gaming X 4gb runs at about 65-70C with virtually no sound. The strapping is easy. Just ID the chip and determin the 1500 for the Hynix or the 1750 for the Samsung chip.

Changing bios? Title: Re: Mining rig info and recommendation Post by: oportunis on May 29, 2017, 10:57:52 AM Hello to all.
I am also trying to build a mining rig. Looked at your specs, but unfortunately, all RX 470 & 480 are sold out. I'm thinking to use this instead: AMD Radeon RX 570 Gaming 4G, 4GB GDDR5, PCI-E 3.0 Does anyone have experience? I used nichehash calculator: https://www.nicehash.com/?p=calc and there it calculated about 90 days to ROI. Worse than RX 470, but what can u do if nothing is for sale :) Any advice greatly appreciated. Title: Re: Mining rig info and recommendation Post by: HardFireMiner on May 29, 2017, 12:13:08 PM When building my rig, I searched for Strix RX470 but when I waned to buy, they just vanished from most of the stores, like poof, so I put my hand on six Strix RX570. Got it up and running. If you need anything, just ask, where I can I will help.

Got it up and running. If you need anything, just ask, where I can I will help. The same is for me, so I am considering to use rx 570. My specification for rx 470 were this: Celeron G1620 Processor Asrock H81 Pro BTC motherboard / Bibostar TB85 6x GPU - RX 470 DDR3 8GB Memory Kingston 120GB SSD Harddisk EVGA 1000w power supply OS - windows10 Power usage would be 880w, but now I guess I need changing power supply as power usage will be higher. Could you please post what you used?

Was thinking 470 8 MB, is that the best bang for my buck ATM? Thx a lot there is only two option like amd or nvidia, amd is good with dual mining the 470 8gb leave you some margin on soem coin that may require additional ram, but nvidia is very good at the moment on some profitaable algo like skei and zcash, it's up to you, maybe you can try one rig of each one to not stay off the profitability |
