Mining Rig Build # 1 To Mining Rig # 3 – Lessons Learned
Yes, that is 4 big fans for one small GPU!
Oh, what just a few short months mean. I’ve learned so much in the last few months, it’s easy to laugh at how it was in the very beginning. My tongue in cheek intro is followed up by some serious lessons learned so if you are just starting out, check out the video. I wish I had done some more research when I first started, but alas, my screw ups are for your benefit. Watch away!
Hey, check out my first mining rig. I got 1 GPU here that I got off of e-Bay for $1200 and it’s got a pretty light on it and its awesome man. And man, I’m rocking the world here, I’m getting like 22MB hashes ang hash bytes or hash pipe or whatever they’re called man, this is MHS. So, I’m getting 22 and yeah and I’ve got this GPU thing and yeah man and I got 2 monitors because you know 2 monitors is better than 1 monitor. So, yeah so, I got that going and check it out man I’m keeping it cool, I got my 1 GPU and yeah, I got fans man, a lot of fans man. I’m keeping this thing nice and cool, so yeah. So, this is my first build and I’m totally stoked man, totally stoked it’s just dope you know, as dope as it could be so yeah.
Hi Steve here and yeah, I got to admit, I remember how excited I was when I got my first rig. Well here it is several months later and I’ve learned a few things and I want to kind of share them with you. You know when you put your videos up on YouTube you get a lot of constructive criticism which is great, you get a lot of nonsense hate comments I don’t really care about those but you know every once in a while you get some really really good nuggets and I want to share with you some of things that I did wrong with my first rig save you from making the same mistakes.
So, number 1: when I first started I knew not to use Molex plugs to run the risers. You know it’s weird when it comes to power options for your risers I’ve heard some people say that Molex is better, I’ve heard some people say that SATA is better, based on the reading that I did, I noticed that most people were saying to you SATA. So, I was hooking up 2 risers to each of the SATA cables which have a max of 3 or 4 but I was only using 2 and I thought that I was fine and one of the pieces of criticism that I got coming out of the gate was to not use them at all but to use a 6 pin to 6 pin connector as shown here. And I just want to let you know that I thought this was a really really good recommendation knowing that I’m taking advantage of using the best connections possible to avoid a fire or any harm to the rig or the house.
Another important thing that I learned and yes this is embarrassing but you know beginners are going to make mistakes I actually had my fans on the wrong side of the GPUs and within 24 hours of posting my very first video somebody pointed out to me that my fans were on the wrong side. And I flipped my fans around and the cooling went from decent to really really good and I’m so glad that that person had pointed that out to me it was of a tremendous help and you know once again if I haven’t posted it on You Tube I probably would not have known about that.
Number 3 is BIOS modding and the proper way of bios modding your GPUs. When I first started I knew about BIOS modding my GPUs and I went out to a website and I used their mod and of course it bricked the GPU and I spent the better part of 3 or 4 hours actually having to boot into DOS and going through a nightmare of basically unbrick work GPU. So, I learned the proper way to BIOS mod the GPUs, I’m going to make a video about that and I’ll put a link in the description but obviously that video is going to come after this one, so that’s kind of an important one.
The next thing was cooling. Kind of made fun of myself here with all these fans I thought the more fans and better especially when I got to 8,10,12 GPUs I ended up learning that it’s not necessarily how many fans you have but getting the heat out. You’ve got to evacuate the heat in the room. This room at one point was 90 degrees and I had 4 fans going which is basically recirculating 90-degree heat. And it wasn’t until I read somewhere instead of having the fan in the window blowing more in I needed to evacuate some of that heat. So, instead of having 30 million fans make sure you’re getting rid of the heat that’s in the room and try to keep the room temperature a little bit cooler.
The next thing I learned is something that I knew going in but I underestimated it and that is electricity. Your common household circuit is a 15 Amp circuit which means that all the circuits in this room are good up to about eight hundred watts. So, once you start stacking on the GPUs you’re going to blow that circuit and then you can be running cords into the neighboring rooms which may or may not piss off your significant other. At one point before I had the electrician come in I actually had the 15 Amp breaker in here completely tapped out, one going down the hall into the bedrooms and one going down the hall into a bathroom. So, at this point this room has several dedicated 20 Amp circuits but yeah it did cost a good amount of money to have the electrician come out and basically rewire everything. So, there are things that you can’t even conceive to think about when you first start especially if you decide to go big and when I say go big I’m thinking probably 3 or more rigs, 3 or more rigs, even 2 stacks of 8 really really heated up the room and that’s why I ended up getting the tent. The tent has been a tremendous blessing in terms of keeping this room nice and comfortable and keeping everything cool. I feel like I can go probably 4 or 5 rigs in that tent and still keep everything at the temperatures that I want to keep them. So, from a cooling standpoint the tent, the duct work, the wood for the windows I mean all of this stuff adds up.
Another important thing that I learned was under volting the GPUS so that they’re not pulling as many watts which will obviously save at the end of the month when the electrical comes.
So, those are the main things, there is probably others that are not just coming to mind right now but you know my whole goal with this channel is to share with you the lessons that I’ve learned, I am no pro at this. I’m figuring this out as I go along, reading, taking notes from other people, getting constructive criticism from my own videos, that’s really the reason why I put my videos out is because people say hey you know you are a dummy, you’re doing this wrong or you’re doing that wrong or hey if you just put this here you’d be able to do a little bit better. So, anyhow, hopefully you found this helpful, I hope so. If you found value in the video please like, comment, subscribe and if you have any questions about the gear that I’m using look in the description below I’ve got links to all the stuff that I’m currently using.
So anyhow this is Steve signing off till the next video, thanks for watching.
