Topic: Want to get back into the game (Read 551 times)

any alterantive for biostar z170? they seem a bit pricey right now. Have you also tried adding more GPUs to it up to 5 or 6?

1. Not the same, it depends on what memory chips you get which is random. Also Strix from what I've read doesn't have RAM cooling so I'd pick one of the others.
2. I personally use Windows so I don't know much, but I know xRDP on Linux can do the job.
3. Even if you order the same, the chips will most likely be different. Many manufacturers use 2 or more chip vendors even for the same graphics card. Unless it's the highest end model in which they usually stick with Samsung. Though you can easily see what memory you have with something like GPU-Z on Windows. You'll just probably have to make 2 BIOSes for each memory chip for the different memory straps.

They are all around the $400 mark so you're saying that they will all do the same rate until they have been clocked?

Thank you for the link - I will definitely have a read up on it and look into pushing more out of them!

So it's not really worth getting ethOS? - I'm fine setting it up on linux have done that before - can it easily be set up however to keep an eye on the rigs remotely ?

sorry for my naivety here - but how would the chips be different? surely if I order the same they would all come with the same that would be able to flash them?

I already have a motherboard and PSU etc that I can use in the mean time - I'll have a look into a better motherboard for more GPU's at a later date.

I live in Australia and had a ahrd time finding RX 580's however have found somewhere to get them from.

I am just starting small at the moment ~$1500 but if I find out im making some money I will be dropping around 5k into it to start with.

What sort of hashrates did you get with that setup?

What really matters is the memory they have and what memory clock/timings you'll be able to achieve. So get the cheapest of the three because memory chips are a lottery.
You should definitely read up on modifying the BIOS. Being able to copy memory straps would be great, modifying the timings by yourself would be even better. Generally you should be able to achieve 2000MHz+ memory clock with a timing strap of 1500MHz for Hynix or Micron or 1750MHz for Samsung or Elpida.
I'd suggest starting from these threads:

https://bitcointalksearch.org/topic/custom-ram-timings-for-gpus-with-gddr5-download-links-updated-1758267 (the entire thread, probably)

Stock settings will get you 22-24MH/s on all these cards on ETH at ~150w, modified BIOS and overclocking, as well as core undervolting and underclocking the core, will get you 28-31MH/s at ~90-100w.

ethOS is just a plug and play solution and does not yield better hashrates, though may consume less power when compared to Windows. Use a normal Linux distro instead and save $40.

Other than that, think carefully about your motherboard and remember that if you order multiple cards that are the same (Nitro+ for example), the memory chips may be different so you can't flash the same BIOS on all of them.
It'd be best that you get at least an 80Plus Platinum PSU for a superb efficiency. Though mining is profitable even with $0.20 electricity.

where do you live?  country is good enough.

most rx 580 are sold out.

how much are you willing to spend?

here is a nice build I did using nvidia

parts are available in USA

So I used to mine BTC about 5 years ago and after it got too hard I stopped.

I now want to get back into the game and am looking at mining ethereum , as such I need some help building my rig.

I am looking at either of these three graphics cards

MSI Radeon RX 580 Gaming X, 8GB

Sapphire NITRO+ Radeon RX 580 OC, 8GB

ASUS ROG Strix Radeon RX 580 TOP Edition, 8GB

Which would be best to go for ? which would get me the best hashrate (and what would they be? - I've seen alot of different figures thrown around for these three , hoping somebody here has some solid evidence)

Cheers for the help!

Also looking at installing ethOS - would that support being able to swap between a more valuable coin?

Also what else do I need to think about / get for the rig?

Cheers
