 Bumping to the top.  threads one two three four are locked and together

Phil,

Could you please update title according to new status and put in first post on your current rigs

People asked the same questions every day on MB, PSU etc

Looking on your config many of them can just replicate

I'm quite interested in your concept on 4 cards on one MB

So if you will have a time - we will appreciate it!

I will probably get rid of all but 2 GPUs. Maybe even sell them as fully assembled rigs. I game pretty frequently so it would be good to have a crossfire setup.

It seems your two 460 has the same hashing rate of one 470. Do they have the same power consumption?

You can always mine X11 with that Tahiti based GPU and get about 11MH/s with the optimized bin file.

For the last 48 hours I think you would of made a little more with X11 than ETH according to Nicehash.

Uses a little more power however.

Point is well taken - should be much better after 19th

i am adding 1 more card that is it.

the rig can do 3 cards but two will be enough.

I dug up a plat psu and my watts are 185 for 19 mh

I am also mining to an exchange  rather then to my wallet since these will just be cashed out.  Will cash out at the exchange once a week.

I do have a wallet and can mine to a wallet if I want to.



keep those cards you may as well hook up a rig for a month make some coins then play videos with them.

I will never go back to my 23 gpu  11 pc days .

I would build 2 gpu rigs mine underclocked for 2 months then sell as gaming/mining rigs on ebay too much work.  Made money though.

the 460's pretty much suck.

but this rx 470 at new egg is 199 and a 15 dollar coupon with your visa = 185

I have 2 of them and 1 on the way.

Nice little system Phil.  It looks like with some riser boards you could get at least 2 more cards connected to that mobo.  Let me know if you want those video cards back lol.

Phil,
Thank you for the service to community!

I definitely will wait till 19th of August and buy 4 RX 480 manufacturer's overclocked and with custom cooling. Will overclock it to 28 MHs and use

Philip, very happy to see you stepping foot in the Ethereum world! You're work in the BTC community is wonderful and I learned a lot from you when I was first educating myself with crypto.

Nice starter rig, now grab a few more GPUs, build a nice frame, and get those puppies on risers! BTW what mobo is that? How many PCI-E slots can you expand with? I think that board has 4? (2 PCI-E x16, 2 PCI-e X1).

I have 8 GPUs running right now on 3 rigs. (I took the money I was going to use on that Avalon6 Group buy and built my Eth rigs).

Currently running:

4x 280X - approx 21 MH/s each
2x 7950 - approx 19 MH/s each
1x 7990 - approx 19 MH/s one core overheats and will not hash -  need to take apart and try reapplying thermal grease. Can't find any program to undervolt it properly either.

According to kill-a-watt i'm at 1550 Watts total power draw. I've undervolted half the cards to around 1.1V, some I have not had time to adjust. I think I've saved around 150 -200W total so far by doing this.

Total Hashrate: ~140 at 1550 Watts

EDIT: BTW the $1400 I was planning on using for the ASIC miner netted me a profit to date of $3200 by going with ETH. A lot of that had to do with getting into Eth just before it blew up, but I think alt mining can still be more profitable than BTC especially with no new hardware being released from bitfury or bitmain (16nm tech that is). Cheers.

my testing is a service to the community.

I just setup two rx sapphire rx 460's  and as expected they are not so good  not a surprise but testing is the only way to be sure.

i can not get higher then 12.5 mh with them. so 2 did 24.9 mh  grand total which is not much

the only case i could have for the sapphire rx 460 miner is it has a dvi jack and a hdmi jack and a display jack.

the rx 470's i have do not have a dvi jack. sometimes  the dvi jack works on a card and the hdmi does not.

I have seen this issue since AMD hd 4770 cards MINING BTC BACK IN 2012

So if you were building a new build and got 5 of these rx 470's at 185

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202230

and had a hdmi issue  you could add a rx 460 sapphire  with its dvi jack  other then that it looks bad.

SO i still am rating the rx 480 if you find an 8gb under 250  a little better then the rx 470  4gb sapphire for 199.99.

mostly i like my 4 card rx 480 builds a lot.

but one card above is 260  the 8gb diamond  so 4x 259 = 1040 for 95-102mh avg  the rx 480x reference 8gb models

the other card is 200 the 4gb sapphire so 4x 200 = 800 for 84-88mh avg the rx 470x reference 4gb models

it was more one month ago and it will be less in one month, probably half of it, it's better to have always one rig prepared for those profitable waves

1 card will not squeeze you enough those good waves, you need to increase the total hash, it's a business on a smaller scale than asic, but it work even better some times

It will be interesting to hear your results on the 460 cards, just looking at the hardware details I predict about half of what you get from the 470 card.

If you manage to get over 14 MH it would be pretty impressive given the power usage and specs

I like my cost for the rig = $0

I like my power cost 25 usd per month at worst in the summer.

200 watts is also pretty low on heat  so I do not worry about cooling it off.

I ordered a card today from Amazon .

I will post on it once I set it up.

So why you go with 460 instead of 480's all the way?
Are the 480's so hard to obtain now that you had to downgrade to a lesser card?
What is the difference from the 460's to the 480's anyways? If not by much then I will consider favoring them if they are cheaper by a sufficient amount.

last of the threads.

I was pretty angry about the april fools joke last year and deleted most of this thread.

Looking back at that action I regret I did it.

I now have my 8 older threads all in time order.

I may ask loyce if he has records on this thread. And try to restore it.

Just cleaning this up due to corona-v

Ocminer has more than one dagger-hashimoto pool.

Nice ghettorig btw...

Don't really care as I don't want to go down the rabbit hole and end up with 10 pc's running 30 to 40 gpus.

I ordered an r7 370 from amazon  a 4gb model should get 15-17mh  but use under 140 watts.

I dug up a platinum corsair and tweaked the hd7970 to get about 20mh at 185 watts.

if I end up with 35-38mh at 325 watts I am fine with ethereum.

I have a photo of a cleaned up setup.
It is so quiet I can watch tv sitting 2 feet from it
