AMD RX580's - The best ROI Card - IMHO


#148

Noob here and this is my first post so go easy haha.
Looking to build a mining rig and not sure if the ROI is the correct way to look at this.
The basic data here is direct from itzone’s chart above.
If after 2 years I’m going to be thousands richer from buying the Nvida card then shouldn’t that be the choice assuming the budget will be okay.
Out of the 2 year position (which is net of card purchase) would come Rig build (which presumably is same except for heavier power supply) and power cost; perhaps electricity use is a bit higher but there is another cost that outweighs this and that’s my time and effort.
Just saying I’d want to be the most $ ahead for the investment of my time and energy.Returns
Now to try and find cards … that might be the deciding factor haha!


#149

Here is a video I did on ROI.

It will give you a good perspective of how I view ROI and selection of what kind of rig to build (Nvidia or AMD).

Here is my Heavy modification of Pigsfoots spreadsheet


It now handles international currencies and live updates the exchange rates
Uses live Crypto currency pricing, handles different cryptos so you can check returns on different currencies.
Compares different GPUs and returns on them too.
Allows for varying number of Rigs and cards per rig.
I did it for me but you might easily modify it for yourself if you have a bit of excel up your sleeve, love excel.
Some of the assumptions are not perfect so feel free to share improvements …
I bought 12 cards tonight and will be pretty busy…

I finally picked up some gear to get started! Starting from scratch, new mobo and all. Picked up two XFX rx580s (I still cant really follow all the memory and manufacturer differences…).

I had been planning on cashing out a little in December and buying a whole 6 GPU rig…lol might not have been the worst idea, but at least now im confidant ill be able to get it working after playing around with xmr on my 10year old desktop and fairly modern gaming laptop these past few months.
My dad was building computers around me when I was a child, so its been great to reconnect with myself and reawaken old hobbies…that’s enough profit in itself tbh :slight_smile:

I read a couple guides on here back in november and december, so I am looking forward to revisiting these in the near future and buggin some of you OP’s with equipment in hand :smiley:

figured I start with Ubuntu…

Thanks Pub :+1:

I just thought I would pop in and report on how my 6 gpu rig is going.
I am running 6 x RX580 8GB on claymores 11.5 on windows 10 which I have set to reboot every 24 hours to keep it reliable ish.
Still running at 31.2 at 880w nice and quiet and cold on 1kw psu.
I am getting 0.05 eth every 86 hrs so almost exactly 0.1 a week (there are 168 hrs in a week).
This works out to 5 eth a year so we are still looking pretty good :slight_smile:
I am half way through setting up a second 6 x gpu rig but this time I will use second hand GTX 1070s and 1070Tis.
I’m making similar returns with the nvidia setup on windows lite with DSTM on equihash.
This works out a similar price now that the prices have gone mad and gives me more options especially for resale if the rumors about the bitmain miners are true.


#153

looks like your 6 GPU rig table has typos - I think it should have the AMD GPU names in it. But it has the same Invidia ones as team green above.


#154

You are correct. Someone else pointed that out to me after I made the video. It’s ok though :slight_smile: I think everyone saw the point. They probably see the point more now than then.


#155

thought so - but wanted to make sure, and at least you know someone actually watched it :slight_smile:

@Pigsfoot
Hi Hows it going ?
Can you please post your Hash rates and Pool/GPU settings?
I was getting 22 MH/s per card during my trial solo mining but only getting 9 MH/s at https://ethermine.org/

Hey guys just a quick one. I bought Sapphire Nitro+ Special Edition cards because they were overclocked from the factory, however, I still see people overclocking them further to get 30-31MHs. I have also seen people overclock the regular Nitro+ cards and get 30-31MHs.

So my questions are: Should I have just gone with the regular Nitros instead of the Special Edition? Or does the Special Edition offer something more than the regular Nitros?

I’m asking because I plan to purchase some more cards and I want to know if to get the Special Editions or the regular ones. Thanks.


My First rig up and running

The Nitro+ cards are the exact same GPU chip as the reguar 580’s. Typically the Nitro+ or any AIB card that is pre-overclocked is that the GPU’s have better cooling and the chips are binned to garuntee the speeds.

For example a Strix 1060 will have a higher base and boost clock than the Duels. But you may still be able to buy a Duel and get it to OC higher than your Strix.

All this boils down to is Silicon Lottery and cooling solutions when looking at it from a mining perspective. When looking at it from a gaming perspective are other nuances or addons that make one more appealing than the other. For example the Strix 1080 comes with two fan headers so that you can control two intake fans at the front of the case based on GPU temperatures. I am not exactly sure what options the Nitro+ has exactly but it will fall into the above description.

I should also mention that typically the higher end cards of each GPU series typically have better memory. I have yet to get a Strix card that wasn’t samsung memory. This ranges from the 1050ti to the 1080ti. As to where my 1060 3gb ACX’s from EVGA vary on memory as it is a lower end model of the 1060’s.

Hope that gives you some clarity on your questions.


#159

Thanks it sure helped. I would agree that the better memory may be reserved for the higher end cards, but I’ll update this post after I verify mine. I’ve had a set-back in setting up my rig because we typically get a short blackout about 3 times per day where I live (along with low voltage and some high spikes). So plan on buying a 1500W UPS today to protect my equipment and finally get it setup.


#160

I did the same. In my line of business I run across these fairly often so I have one on every machine. Even once the batteries are no longer useful they provide decent power conditioning.


#161

hi guyz, can anyone help me solve this problem

“GPU #2 got incorrect share. If you see this warning often, make sure you did not overclock it too much!”
i encounter this when i tried to tweak my rig. i have 2 rig with 5 rx580 rig1 with all hynix memory runs smooth this rig2 i encounter this problem. heres my claymore setup

EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x2dA0cD3024Ca2F7d942c98BF8De88B181e68a7Aa/Worker1 -epsw x -mode 1 -ftime 10 -etha 0 -cclock 1250,1150,1250,1150,1150 -mclock 2150,2200,2150,2200,2200 -mvddc 900,880,900,850,850 -cvddc 900,860,900,850,850 -tt -50 -ttli 70 -tstop 75 -fanmin 30 -fanmax 100 -platform 1 -eres 3

Hope someone can help my problem

TY


#162

Not sure if you solved this already.
Here is my batch file for 6 x rx580s with hynix all except the second card which is samsung.
Runs smooth at 31.2 Mh/s
I would suggest replacing the thermal paste with kryonaut thermal grizzly.
Make sure you have the latest claymores miner.

I did a comprehensive pool test also and found ethermine.org better at the time.

timeout /t 30
EthDcrMiner64.exe -epool eu1.ethermine.org:4444 -ewal 0x03BEF224EAf3b41c18DAE95282a611879cf9c77d.RX580 -epsw x -mode 1 -etha 0 -cclock 1200,1200,1200,1205,1200,1205 -cvddc 860,880,870,860,860,860 -mclock 2180,2100,2180,2180,2180,2180 -mvddc 885,860,880,865,855,860 -tt 60 -fanmin 24 -platform 1 -eres 3 -tstop 80 -tstart 50 -dcri 14,8,14,14,14,14 -mport 0

#163

What i did is i set default value on cvclock mvclock on claymore. I made no overclock on samsung bcoz if i overclock i got tons of memory error. But still i manage to achieve a 30mh with 110wtts power draw. Thanks by the way for the rply. Much appreciated

Somebody is mining into my wallet listed in one of the posts above.

BE SURE TO CHANGE THE WALLET ADDRESS TO YOUR OWN WALLET :smiley:

Good hash rates btw :stuck_out_tongue:
