what is it?, looks like an asic single or something

Hello, This is my first mining rig, done entirely in aluminium 3mm thick, screws are all 1/8 directly screwed to the aluminium (previously threaded) (is that well said?, english not my first language, don't know how to explain it properly).

The original plan was to put 5 boards, but I'm pretty close to the power consumption of the power supply (750W PSU, and I'm using 450W for 4x7850 and the sempron processor).
the HD is temporary as I plan to boot from a flash thumb drive.

This gear gives 1GHash/s (BTC) at stock speeds and eats 450W, I know, small for what i have seen here but it's my first attempt, hope u like it.



other view:


side, with only one card and the cablesaurus extender (they are great!)

Shit man this is one kick ass setup, I love it!, excellent idea! but
How do handle the heat in the upper rig?

I have 2 setups done with aluminium profiles, and the top one gets hot as hell so I had to put them side by side to prevent this.

Excellent rig!, impressive!
What is your production and power consumption?
I have read that those gigabyte 7970 are voltage locked

Thanks 
I buy them, they are for electronics (not PC), I actually had them from a previous project they are quite expensive, like 0,4 U$D each.


Yes I know , I am runing at stock (860 Mhz)  I will love to get more juice from them, but i don't want to destroy any, GPU's are expensive here and have no warranty in my country.

The hottest card (the one closest to the PSU) runs at 60 C, so I think that i am ok with the temperature so far, but not sure how safe will be to OC them.

What is the board in the bottom left, looks like relays, what is that?

Thank you
I have a thermal paste similar to that one (same brand) that works pretty good.
I didn't know that I should change the thermal pads from the memory also.
one question, these pads are good for VRM's as well?

thanks for the info!!

Woohaaa!!! That really really good setup!!
It's quite similar to what I have build but your vertical placement approach is FAR BETTER than mine, you can fit a lot more of cards, and natural cooling should be a lot better!!!

I was just planing to build two more rigs, and I think I will do what you did!
excellent idea!

where do you get TIM replacements from? which ones should I buy? I have 1 7950 that no matter what I do is always 6 -7 degrees over the other ones, probably that is the case too (sapphire 7950 oc boost) also have another sapphire 7850 with heat problems but it's because one of the fans are acting up

You are right, I contributed to this mess as well , will remove pictures next time

Nice!!! I like it!
What are the difference when the upper fans turned on or off in temperature?
I was wondering to do that but not sure of the results, as every fan I put in my gear no matter where, it only make it worse.

thanks for the info!
What should I be looking at?, in the pattern I mean, other than the paste is well spread?

Thanks!
I started having this issue today just on one of the three miners i have with 1060 3GB cards, ODD! -eres 0 fixed it, thank you.

indkt.

Worked!, Thanks! 

Hello
I have been following this thread for a while
I administrate several asic farms and GPU farms, I own GPU farms.

the thing is easy ,as a general rule (it goes up and down obviously)
Asics require 2X to 2.5X more power consumption that GPU at the same profitability ratio.
Asics usually costs half of what a GPU rig costs at the same profitability ratio.

so in order, lets say, to produce 5 USD/day youll need 1 Rig of GPUs NVIDIA that will consume 650W or an asic that consumes 1600W

and yes the cost of the GPU rig is probably twice the cost of the ASIC.

but remember, power is everything, power determines how big can you go, how much can you expand
rent a place its easy, cooling it's hard but doable once you learn how the air dynamics works.
power....... it is another matter

you cannot request a: let's say 500KW in a house, the power company will refuse, it will request you to present the proper papers, as a company, since a house cannot use that level of power, as a company you need to exist as such, and pay taxes and all,and even so you still need permissions from government explaining what are you gonna do with all that power.

Anything above 300KW will probably require you to have your own high voltage transformer that will probably cost close to 100K USD plus instalation and proper certifications that takes a lot of time and money to do.

so, unless you plan to have only a very few asics in you small flat, if you want to go big, the only way is maximum power efficiency, and that it's not ASICS, it's GPU, do the math, buy both if you wan't and compare profitability vs power.

most people I know, got tired of GPU because they are difficult to configure, yes they are, but right now NVIDIA 1080Ti and AMD VEGA are the the most efficient GPUs in the market, it takes a lot of effort to make them work at maximum efficiency, but it worth it, and allows you pack a lot more of production in the same place and power capacity than will allow you with asics.

remember, power it is your ceiling , not money, power capacity is what tells you how high can you go.
cheers

+1
Agree
immigration is destroying our way of living as well.
this does not looking good

They have been claiming that for about three years now and we a still mining hehe, I don't believe them LOL

Don't mine with a laptop, ANY laptop, even the biggest Alienware or MSI gaming series will produce nothing and we are talking about several thousand dollar machines!.

specially with HP!, HPs are poorly designed machines!, you'll endup killing it in no time.

Notebooks are designed for low power, mining requires insane amount of processing power and  that requires.... well.... POWER so no, build a rig specifically for mining, BIG ASS PSU, POWERFUL GPUs, if you don't have much money start small like I did, i started mining with two used AMD 5830, then sell them and buy two 7850, then 7950 eventually endup with a big farm that produces more than my work does hehe
but takes time and effort and money , LOTS of money.

you'll get there eventually, invest small but constant, read, investigate, and start small, but with the proper stuff, notebooks are not designed for that.
cheers

Really?, at 4.5 USD/day @ 1600W power consumption at the wall the profit is marginal at best, GPU still get you twice the profit at the current power consumption if you aim at maximum power efficiency

If you have free power yes, if not ASIC, it is not profitable.
FPGA only if you design your solution in-house, you'll have an edge, otherwise will not, either.
