Guys,
Did you consider to install an addition GPU cooler on card like this
https://www.amazon.com/ARCTIC-Accelero-Mono-Graphics-Cooler/dp/B006DAD8HS/ref=sr_1_9?s=pc&ie=UTF8&qid=1469241260&sr=1-9&keywords=gpu+cooler
That may decrease card T during the dual mining in overclocked cards
Any ideas?

Just saw the R9 480 announcement...
480 just as good as 390 in terms of raw power and 150watts only, and it retails for $199 !!!
This is really good timing since we need powerful GPUs suitable for ETH mining, draws less power and recyclable for a decent gaming rig!

it will consume less, right now a 1070 has the same tdp and can do 27MH with only 100w
tdp is just the target the real consumption can be tweaked with the mv in play
buying nano right nano is a bit stupid with those gpu, i would wait
I have a Nano rig now in progress, 6 x Nano, 175.8MHs with 1100watts !

He may want to overclock. coins are shooting to the moon .
He can certainly go low as you say. my 4 cards of rx 480 and the rig are just under 600 watts and do 102mh.
my 2 card build with 1 r9 390 and 1 rx 480 is overclocked and pulls say 510 watts to do 57mh-58mh I over clocked cause prices are way up/
Got you both!
Yes - I'm overclocked 3x R9 390 to 1050Mhz (from stock 1015 MHz)
So power consumptions is for overclocked, undervolted cards
June 03, 2016, 02:34:45 AM
I will mine the Etheruem mainly in the next year also, before it goes PoS. So I will wait for the wide memory bus cards, not the 480.

Phil,
I have 4x R9 390 - I'm reading in kill-o-watt 1320W from the wall (PSU 1300W Gold 80).
Can I use 3x R9 390 and 2x RX 480?
Or that will be overkill?
What is about 2x R9 390 and 3x RX 480?

I am about to start a thread on mixing r9 390's with rx 480's
I just finished taking 12 photos.
I think 2 r9 390's and 2 rx 480's
will use 1010 to 1050 watts at meter since 1 + 1 in my case is using 504 to 526 watts my meter reads 2.1 amps at 240 volts but could be as high as 2.19 amps
So I think 2 r9 390's and 3 rx 480's would use 1200 watts to 1300 watts (guess) as your clocks matter

If you undervolte, you will not use more than 1000W with 3x 390 + 3x 480. So why do you need more than 1300W?

256 bit memory bus vs much faster memory.
480 should be a good miner card, just not "better than anything before".
More likely will slot in around the 380/380x range NOT the 390 range - narrower memory bus though faster memory will probably overall hold it back some.
It SHOULD do well to excellent on hash/$ and hash/W, just not going to be killer on raw hash numbers based on available specs.
The BIG question is going to be IS IT GOING TO BE AVAILABLY IN ANY QUANTITY - same issue that's already plaguing the GTX 1080 very badly, I have a bad feeling it's going to impact a MAINSTREAM card even harder, but hope to be wrong.
Keep in mind based on raw stats that the GTX 1080 should be a KILLER miner - yet it barely outmines a lowly GTX 970 - there's issues somewhere in ETHEREUM causing scaling to NOT happen well on any higher-end card, especially NVidia but affects the AMD line as well (or the Nano and Fury cards be killer ETH mining cards instead of just a high-priced efficient ones).
Academic for me for the next month and some though, I've found out the hard way I'm pushing my "limits of available power" pretty hard already, really looking forward to a move to a place with cheaper power and more than "pair of 50 amp service" availaibility.

If the question to me - I do not need more than 1300
All my r9 390 are undervolted to -100mV via MSI AfterBurner

I think in the same topic it was questioned that 480 can give 31MHs
By power consumption is obviously better
July 22, 2016, 11:32:56 AM
Do you guys think that non-reference cards will in stock around third week of August?
Yeah right before college starts back up.
So your +12V into your motherboard slot isn't hot?
no remember you have 4 wires and 2 wire going in a total of 6 wires.
Hint cpu jack has 4 hot wires and while many think it is all cpu many mobo's pull some power from it.
I tweaked more and am doing 592 watts and 102mh for the 4 cards. this is at the
kill a watt and reflects the entire power used by the system.
apparently the newest catalyst has some power-draw updates to limit draw through the mobo. Also helps that ethereum mining doesnt quite demand full power draw from the cards
theoretically the mobo should have the ability to safely draw 300W through the 6 hot 12v wires, enough to support 60-75w/gpu if the cpu/ram/fans attached to it are not power-ungry

if your pockets are shallow don't build a six card rig as they are a mining rig.
I like 2, 3, 4 card rigs that can fit in a case and be used to game with.
you also have flexibility to mine completely different coins on different pools.
and there are good psus that will do two or three cards easy.

Don't skimp on the GPUs. Sapphires are only $10-$20 more, or at least go Asus/EVGA/Gigabyte/MSI.

That SSD is serious overkill, can save $50 easy by going with a 50-100 GB M2 SSD if you insist on one, or go with an actual hard drive. I've been seeing some 2TB units in the under $50 range (refub), HGST is NOT cheap stuff (I've switched to them the last couple years over WD after doing some research and watching Seacrap run WD reliability into the ground).
Should also be able to save some $$ by going with an AMD motherboard/CPU vs Intel - Intel boards and CPUs tend to be noticeably more expensive, while eating comparable power (both have quite a few 45Watt TDP cpus for commonly-available sockets).
My 2-card rigs are using AMD motherboards that cost around $65 as I recall, but I didn't go "low end" on the CPUs (A10-7860K is severe overkill for a "mining" machine, but I have other uses for the GPU on those).

this rig will pay for the 2 cards in 70 days. sell them at that time and order the newer r9 480
July 22, 2016, 08:00:58 AM
That's pretty impressive.
So if power consumption wasn't an issue whats the fastest that the 480 can mine at? 29MH/s ?
So if power consumption wasn't an issue whats the fastest that the 480 can mine at? 29MH/s ?
Maybe 28 or 29 .
The ram memory can set to 2200/8800 with wattman for tweaking the gpu and with claymore to mine 28 for sure maybe 29.
This card is far better then the r9 390. I can get that one to do 33mh with heavy overclock and claymore but is sucks up tins of power.
For me power is important and heat is more important.
I have the 4 card rig all rx 480's up to 102 mh at 590-600 watts.
I have 2 2 card rigs with 3 r9 390's and 1 rx 480 at 560 and 480 watts they do 112mh
So 1630-1650 watts for 214mh
In the summer that amount of heat and power approaches my max.
It is about 1200 kwatts a month at 18 cents = 216 usd but I should earn 536 usd net 300
In the winter it is about 9 cents or 108 usd.
I wish I had used all rx 480's
2 four card rigs at 102 each = 204 mh and 1 2 card rig = 51 mh 255mh net
power would be 1500watts
mh would be 251mh
vs my
1650 watts
214mh
In the winter I can see me at all rx 480's
3000 watts and 500mh
