1
00:00:00,080 --> 00:00:07,359
for months now graphics card supply has been completely tapped out thanks to

2
00:00:05,120 --> 00:00:10,960
every gamer's worst enemy miners

3
00:00:08,480 --> 00:00:15,599
and no not young people who screech into the microphone but they're awful too i'm

4
00:00:13,360 --> 00:00:21,119
talking about the kind of miners who are using hardware both pc components and

5
00:00:18,720 --> 00:00:25,439
more specialized equipment to calculate what are called

6
00:00:22,400 --> 00:00:29,039
hashes for cryptocurrencies like bitcoin

7
00:00:25,439 --> 00:00:32,800
in exchange for a reward effectively

8
00:00:29,039 --> 00:00:35,280
mining for money but how do you get in

9
00:00:32,800 --> 00:00:39,280
on the action can you just fire up your old pc and start making

10
00:00:38,079 --> 00:00:49,600
money let's investigate

11
00:00:49,600 --> 00:00:57,440
mass drop is now featuring their custom configured akg k7xx audiophile

12
00:00:54,960 --> 00:01:02,480
headphones check them and other drops out at the link in the video description

13
00:01:00,480 --> 00:01:07,840
let's get this out of the way first uh to make a gold rush analogy the days of

14
00:01:05,360 --> 00:01:11,360
walking onto a random plot of land you know sticking your pickaxe

15
00:01:09,840 --> 00:01:14,159
scissors or whatever into the nearest mountainside and sailing home in a

16
00:01:12,960 --> 00:01:19,680
golden ship are basically over but just because

17
00:01:16,960 --> 00:01:24,880
mining the most popular cryptocurrency bitcoin is no longer practical for the

18
00:01:22,240 --> 00:01:30,080
average person with uh an extra graphics card or two

19
00:01:27,600 --> 00:01:35,200
that doesn't mean that you can't mine for something so as always around here

20
00:01:32,960 --> 00:01:41,360
we started our adventure with some overkill hardware bringing our 10 GPU

21
00:01:38,640 --> 00:01:46,880
server out of the motherballs uh from eight gamers one CPU theoretically 1080

22
00:01:44,479 --> 00:01:51,119
ti's are the most profitable but we have to ignore cost to buy what do you mean

23
00:01:49,119 --> 00:01:53,600
ignore costs to buy what do you think i'm like made of graphics cards can we

24
00:01:52,560 --> 00:01:58,719
use these so then what we ended up with is

25
00:01:56,320 --> 00:02:03,439
five gtx 1070s uh four gtx 1080s and then a single 1080

26
00:02:02,399 --> 00:02:10,000
ti it's not going to be like the highest earning rig but we can use this to run

27
00:02:07,759 --> 00:02:14,480
some important benchmarks and determine whether our plan will be profitable i

28
00:02:12,560 --> 00:02:18,080
guess we got to take it upstairs um one trip yeah sure

29
00:02:16,080 --> 00:02:21,040
i was about to say the same thing oh gosh

30
00:02:19,440 --> 00:02:24,720
come on it's just like complete disregard it's fine who cares

31
00:02:23,440 --> 00:02:27,680
it's like a five thousand dollar shirt oh i care it's just it's fine like we're

32
00:02:26,480 --> 00:02:33,440
just not gonna drop it so it doesn't matter right you got it because you never drop anything okay here

33
00:02:31,520 --> 00:02:38,640
okay technically not the way it's meant to be rolled i don't think but yolo

34
00:02:36,800 --> 00:02:41,599
can you lift it any higher so i got my ankles okay thank you

35
00:02:42,239 --> 00:02:45,680
oh don't shift down like that

36
00:02:45,920 --> 00:02:53,360
you know i think we actually could have fit 11 in here if we use the um the katana i think it

37
00:02:51,440 --> 00:02:56,400
throttles a little bit i think mining on the katana would be a terrible terrible

38
00:02:55,120 --> 00:03:01,519
idea i'm just saying i think we could have while i do this Jake's gonna work

39
00:02:58,800 --> 00:03:08,400
on installing the whopping two sticks of memory out of the 24 slots on our board

40
00:03:04,800 --> 00:03:10,800
here um cryptocurrency mining doesn't

41
00:03:08,400 --> 00:03:14,400
really benefit from a ton of RAM with that said though it may benefit from a

42
00:03:12,560 --> 00:03:18,480
large virtual memory space on your storage drive and then he's also going

43
00:03:17,360 --> 00:03:26,400
to throw in two of our 22 core xeon processors

44
00:03:23,120 --> 00:03:28,239
wait i guess i know that's really stupid

45
00:03:26,400 --> 00:03:32,000
they're just the only two cpus that we had lying around that were compatible

46
00:03:30,080 --> 00:03:37,040
with this board and we actually have to populate both of the sockets for this because

47
00:03:35,040 --> 00:03:41,599
otherwise we won't have enough pci express lanes for all of these freaking

48
00:03:39,680 --> 00:03:49,920
gpus are you struggling yeah a little bit

49
00:03:46,080 --> 00:03:49,920
i don't have enough do you have any more

50
00:03:50,000 --> 00:03:56,879
did this take us less than four hours aha [ __ ] you brandon i was right well

51
00:03:54,640 --> 00:04:00,799
it's because he's here not because i had no confidence in you doing this by

52
00:03:58,640 --> 00:04:03,280
yourself from that time ouch

53
00:04:01,680 --> 00:04:06,480
holy [ __ ] god you're going to drive up all of our

54
00:04:04,720 --> 00:04:10,959
insurance premiums when he has to go to the emergency and get that burn sorted

55
00:04:08,879 --> 00:04:16,639
out and there we have it we are now ready to

56
00:04:13,280 --> 00:04:18,400
boot up our system so actually almost um

57
00:04:16,639 --> 00:04:21,280
cooling is sort of a concern in a system like this so we're gonna go ahead and

58
00:04:20,079 --> 00:04:25,199
throw our fans back in here and then Jake are

59
00:04:23,600 --> 00:04:29,440
you ready with that shroud just gotta get this gaff tape unstuck wouldn't want

60
00:04:27,440 --> 00:04:33,840
to be wasteful you know just are you really reusing tape yeah this tape is

61
00:04:31,600 --> 00:04:37,520
still sticky how cheap do you think i am is this an evon initiative i mean this

62
00:04:35,520 --> 00:04:40,840
chassis clearly isn't designed to have graphics cards um yeah i don't know how

63
00:04:39,280 --> 00:04:46,639
we're gonna fit this in here i think you kind of have to just

64
00:04:43,040 --> 00:04:46,639
cram the tip in between two of them

65
00:04:47,360 --> 00:04:54,479
okay it's like it was made to fit yeah see look at that i like that i got

66
00:04:51,840 --> 00:04:58,160
my reused tape yeah look it's still sticky i told you gaff

67
00:04:56,080 --> 00:05:01,759
tape is amazing you didn't tell me that i did you've never told me that okay

68
00:04:59,840 --> 00:05:07,600
well gap tape is amazing uh so now we just need some power okay

69
00:05:04,560 --> 00:05:09,199
i need four right oh right yeah

70
00:05:07,600 --> 00:05:13,039
dory i planned for this we could have easily done this experiment with just a normal

71
00:05:11,600 --> 00:05:15,840
motherboard and 4g yeah but that would have been so lame

72
00:05:16,880 --> 00:05:24,479
it's like power me please look i'm working on it okay

73
00:05:21,280 --> 00:05:27,039
please give me power i'm failing

74
00:05:24,479 --> 00:05:32,000
come on okay we're in we're in all good ah

75
00:05:28,479 --> 00:05:34,639
yes slightly less annoying

76
00:05:32,000 --> 00:05:38,320
uh where are all the 632 screws from uh right here i have a thing where do they

77
00:05:36,560 --> 00:05:40,720
come from where do they go where do they come from

78
00:05:41,039 --> 00:05:47,520
that was terminally unimpressive okay there we go that's where i like it

79
00:05:45,440 --> 00:05:51,759
that's how you know it's working okay so while we're waiting to fire up

80
00:05:49,360 --> 00:05:58,000
Windows and install the NVIDIA driver which by the way takes a long ass time

81
00:05:55,520 --> 00:06:03,520
on a system with 10 gpus uh let's have a look at power consumption uh we're

82
00:06:00,080 --> 00:06:05,120
looking at 400 watts right now 400 watts

83
00:06:03,520 --> 00:06:09,919
had idle at idle so basically no matter what kind of

84
00:06:07,600 --> 00:06:15,919
hardware you're using mining is going to add a lot to your electrical bill so

85
00:06:12,960 --> 00:06:21,039
it's this real cost that's associated with it that prevents casuals from just

86
00:06:18,160 --> 00:06:27,120
using old hardware to mine these days it is all about efficiency so our pascal

87
00:06:24,639 --> 00:06:32,800
based cards consume a similar amount of power compared to previous generations

88
00:06:30,319 --> 00:06:37,680
but they run the algorithms needed for mining much more quickly than previous

89
00:06:35,199 --> 00:06:44,000
generations and the more calculations that you can perform per watt of power

90
00:06:40,560 --> 00:06:47,440
consumed the more profitable you'll be

91
00:06:44,000 --> 00:06:50,000
the other key is to mine smarter almost

92
00:06:47,440 --> 00:06:54,639
no one is mining for bitcoin directly these days because over time the

93
00:06:52,319 --> 00:06:57,680
difficulty of generating a reward by mining goes up

94
00:06:56,479 --> 00:07:04,000
a lot so people are opting instead to mine for

95
00:06:59,919 --> 00:07:07,120
an altcoin like litecoin ethereum zcash

96
00:07:04,000 --> 00:07:08,400
or even dogecoin yes for the uninitiated

97
00:07:07,120 --> 00:07:13,599
that was and is a real thing

98
00:07:11,199 --> 00:07:17,680
okay without scratching the table oh my god that got a lot heavier

99
00:07:15,680 --> 00:07:20,240
i'm so happy i'm not carrying that side that's fine i'll be on the bottom this

100
00:07:18,880 --> 00:07:24,880
time oh wait i'm going backwards again what the hell no you go backwards

101
00:07:23,199 --> 00:07:28,720
also i just locked this door wait and my elbow needs to

102
00:07:26,960 --> 00:07:33,759
unlock it there we go yeah oh man this thing's heavy

103
00:07:32,160 --> 00:07:37,360
wait why are we standing like this this is not a good strategy yeah um

104
00:07:36,080 --> 00:07:41,280
can you slide that way and i'll slide this way yeah

105
00:07:39,440 --> 00:07:45,599
i got it hey if we drop it it's not that big of a deal so hold on hold on don't push holding

106
00:07:44,560 --> 00:07:51,440
now sort of counter-intuitive

107
00:07:47,919 --> 00:07:52,479
uh other side is in it it is yeah

108
00:07:51,440 --> 00:07:56,560
really are you serious yeah holy [ __ ] that was

109
00:07:55,520 --> 00:08:02,160
painless so um now that it's installed the plan

110
00:07:59,039 --> 00:08:05,199
is to use a marketplace called nicehash

111
00:08:02,160 --> 00:08:08,080
that pairs buyers who want to rent

112
00:08:05,199 --> 00:08:12,960
hashing power with sellers who have hashing power like us

113
00:08:10,560 --> 00:08:17,360
so what's cool about that is that after you run the included benchmark which can

114
00:08:15,280 --> 00:08:23,280
actually take a few hours with this much gear and had trouble with the 88 threads

115
00:08:20,879 --> 00:08:26,879
worth of CPU that we're rocking in this version of the software anyway it

116
00:08:24,800 --> 00:08:30,639
determines which algorithm is most profitable for

117
00:08:28,639 --> 00:08:35,360
which piece of your hardware at any given moment and runs that giving you a

118
00:08:33,440 --> 00:08:40,640
real-time readout of how much you're earning before electricity costs and

119
00:08:38,000 --> 00:08:44,640
then paying you out daily as long as your balance is at least .001

120
00:08:43,279 --> 00:08:51,519
of a bitcoin that is after taking their cut

121
00:08:48,160 --> 00:08:54,640
it's booting right i think so

122
00:08:51,519 --> 00:08:56,880
okay so over the weekend Jake i didn't

123
00:08:54,640 --> 00:09:02,160
really help spent a bunch of time babying this thing through crashes and

124
00:08:58,959 --> 00:09:04,880
blue screens and we have finally

125
00:09:02,160 --> 00:09:09,839
got it mining stably tm we initially thought that the issues

126
00:09:07,360 --> 00:09:13,519
might be related to thermals because let's face it uh the cards are really

127
00:09:12,080 --> 00:09:17,200
close together by the way your ducting seems to be falling off if you want to

128
00:09:15,600 --> 00:09:22,560
go have a look at that um get this ladder in here but with

129
00:09:19,920 --> 00:09:27,680
afterburner up on screen it's actually pretty clear that our climate controlled

130
00:09:25,120 --> 00:09:33,519
server room has that under control we're hitting 82 degrees top some of them are

131
00:09:30,480 --> 00:09:35,120
a lot lower like 70 even that actually

132
00:09:33,519 --> 00:09:38,320
that reminds me we haven't factored the cost of air conditioning into our

133
00:09:36,720 --> 00:09:43,600
profitability equation but that's something that we can really look into during part two of our investigation so

134
00:09:41,680 --> 00:09:48,480
getting back to this machine you might have noticed that there are

135
00:09:45,519 --> 00:09:52,800
actually only eight gpus in the system now see that we pulled out the middle

136
00:09:50,480 --> 00:09:58,800
too that's actually due to an NVIDIA driver limitation that specifies a

137
00:09:54,959 --> 00:10:01,440
maximum of eight gpus per operating

138
00:09:58,800 --> 00:10:06,959
system so shout out to gary over at ASUS for that tip so that means our final

139
00:10:03,519 --> 00:10:09,760
power usage is a cool 2000 watts no

140
00:10:06,959 --> 00:10:12,800
biggie then for our remember four power supplies

141
00:10:11,120 --> 00:10:17,279
let's talk about the return on our investment to buy

142
00:10:14,959 --> 00:10:24,240
that configuration would run you nearly 18 000 us dollars at an average of 11 a

143
00:10:21,519 --> 00:10:28,800
day in profit again not accounting for air conditioning it would take around

144
00:10:26,079 --> 00:10:33,680
four and a half years to recoup that and that is assuming stability in the

145
00:10:30,959 --> 00:10:37,839
cryptocurrency market stability what stability in the cryptocurrency market

146
00:10:35,519 --> 00:10:43,040
right what a joke so obviously this would be a really stupid

147
00:10:40,240 --> 00:10:47,839
mining setup to go out and buy however if you were a little more um how you say

148
00:10:46,000 --> 00:10:52,720
not a complete idiot about your part selection assuming that your power costs are

149
00:10:50,560 --> 00:10:57,440
similar to ours at around 10 u.s cents per kilowatt you could actually get your

150
00:10:55,200 --> 00:11:01,519
upfront investment back a lot sooner so we're going to investigate a more

151
00:10:59,279 --> 00:11:05,600
optimized config in a follow-up video but this config for about five thousand

152
00:11:04,160 --> 00:11:10,480
dollars that you're looking at right now is kind of what we're planning let us know if you have any suggestions in the

153
00:11:08,480 --> 00:11:14,880
comments first let's get back to the original question does what we're doing

154
00:11:12,640 --> 00:11:20,079
make any sense well if you have a bunch of spare

155
00:11:17,440 --> 00:11:22,480
modern hardware lying around collecting dust

156
00:11:22,720 --> 00:11:27,839
actually yes so we're planning to leave that

157
00:11:25,839 --> 00:11:32,000
system running until phase two when we'll report on our results and then

158
00:11:29,680 --> 00:11:36,240
compare it to our second system but if you have to go out and actually buy

159
00:11:34,000 --> 00:11:40,240
hardware to do it your return is likely going to take so long that you'd be

160
00:11:38,560 --> 00:11:44,800
better off doing what many people are doing and trying to buy and sell

161
00:11:42,320 --> 00:11:48,959
cryptocurrencies more directly as they rise and fall though

162
00:11:46,399 --> 00:11:53,680
there are certainly risks associated with that as well

163
00:11:50,720 --> 00:11:59,600
so why did everyone run out and buy all the video cards and high wattage power

164
