Big question remains..

470/480?
4GB/8GB?

(only advantage of the 480 is that it sells better in 1-2 years..)

go for a mix

½ 4gb

½ 8gb

look for best prices

Question how do you plan to keep area cooled off.

The climate here in holland is beginning to cool rapidly now, in a month it will be around 10C.
The rigs will be set up inside a old shed with good ventilation (and some extra fan's ofcourse) and we will just check it for a little while. Maybe some extra airco.

Why a mix or 4/8gb?

4gb are 200 usd vs 8gb 250 usd

so while the 4gb may do a little less hash it is 50 usd cheaper

8gb will stick around long with eth since they can do a bigger dag

due to 2x the memory.

What algorithms you mining?

I want to solo mine ETC for now. It may change ofcourse in a few months.

why celeron g1840

see if you can get g1840t

18 watts less

and when you use a celeron they do tend to use more of the cpu

I highly doubt this. I have a couple rigs with G1840 CPUS, and load while mining eth is <5%.
If I remember correctly, idle power use with no GPUs installed (running off the iGPU) was ~25W.

It may vary from mobo to mobo.

I don't have any g1840's anymore

I do have:

pentium g4500
pentium g4400
i3 6100t

give me some time I will photo them but as I recall my pentiums are always higher cpu loads then the i3 6100t.

I am running 8 pcs 24/7 with various cpu's the t's simply do lower watts on all of the ones I have.

i like the pig tail pcie cable(those that come with 2x 2+6 pin), so with one you can connect two gpu

and the 1300 evga only has two of that, then you need to use two 2+6 pin cable, so 4 in total instead of 3, i like to have less cables as a possible for a clean build

EVGA 1300 G2 has enough 6-pin leads to handle a 6-card rig.
In my limited experience with 2 of them, it's a good PS and kinda overkill for a 6-card RX4xx rig.

it is a bit overkill, but there are not many PSUs at 1100W (which would be an ideal ~70% load). but if dual-mining, you'd be drawing around 130-140w/card, and about 100-150W to the overhead (cpu/fans/hdd/etc). thats ~800-900W, and its good to keep <80% psu load if you plan to run 24/7 for months on end.

if you find some g1840t's try one or two to see if you save 10 to 20 watts a build

this one is pricy

https://www.amazon.com/Intel-CM8064601482617-Celeron-G1820T-threads/dp/B00HLXXGCI

this is the g1840 plain much cheaper

but i did find quite a few g1820t cpus

agreed.

but i sell some wesome 1x6pin to 2x(6+2)pin splitters that can still keep your build clean and powered https://bitcointalksearch.org/topic/24-16awg-pcie-pcie-and-pcie-leads-and-18awg-m-f-m-splitters-6pin-and-62pin-563461

the evga1300 is a great PSU and would only be 60-70% loaded under ethereum or 80-90% loaded if dualmining

Hi there,

I Recently build 3 mining rigs with these components:

- Asrock Anniversary H97 (5 cards per rig)

- 4GB ddr3

- 120GB kingston ssd

- 1000watt RM1000x crosair PSU

- Intel Celeron G1840

- Sapphire RX480 Nitro+ 8GB (5x)

The rigs are running on 135Mhash avg hashrate. About 27 per card (Undervolt & overclock in wattmann) and about 700-725 Watt at the wall.

Since there is no custom bios available for the Nitro's yet, i can not tweak them any further without them getting unstable. (does anyone has a custom bios?)

I want to go big, would you change the setup?

- I will use 6 cards instead of 5

- RX 470 4gb/8gb? or the RX 480 4gb? (can buy the Nitro's 8gb for €299 and 4gb for €236)

- Different PSU?

- Which brand is the best?

- Controlling them on one device from a distance?

- Windows 10/8.1 or Linux?

Thanks for helping me out, I appreciate all your opinions and I'm just here to learn before the investment. Wink
