Topic: Third alt coin thread last two were too big. Builds links thoughts etc - page 3. (Read 41866 times)

And...that page shows the Powercolor RX580 using 296W vs 231W for an RX480.
Maybe I overstated a bit saying 50-100W more, but it is definitely significant. Check all of the other reviews...

of course  but many of us don't do a 100 gpu  plus setup.

for me in the garage   3 or 4  rigs filled with 1080 ti's  will be better then 5 rigs filled with rx 480 8gb.

For a guy with 100 rx 470 4gb using custom flashed cards they make sense due to the extra power save.

 I  have seen claims of a 6 card zec with rx 470 8gb doing 1500 h using 600 watts at the k-watt meter.  that is a nice rig and x it by 50  since the custom rom cost money it makes more sense for that miner.

It is why smaller miners are disadvantaged since custom flashed cards are not cost effective for one 5 card.  So people decide to diy a flash  with good and bad results.

I have a thread with 5 links to  I fucked my card up flashing it.  If I spent a day I would find 100 links here on this site.

When you do a calculation or statement about rx 470 4gb  you naturally don't have this happen to your gear  and you don't factor it in.

I am not attacking you statement I am saying it is based on your setups'  

So what is your dead card or damaged card due to flashing loss  under 2% correct ?

Do your figures with a 10% fail rate for flashed cards. This alters the numbers.
  
 100 flashed 2 bad is 98 good  
 100 flashed 10 bad is 90 good.

that alters the statement. you made.

now lower it to a guy 1 rig six cards  1 dead due to a bad flash  5 good  he has a 16 ⅔ % fail rate
and the next guy  1 rig  six cards    0 dead due to all good flash    he has a 0 % flash rate

first guy hates flashing
second guy loves flashing

first guy was better off with all rx 480 8gb
second guy is like you happy with rx 470 4gb

over all fail rate is 8%  but for one guy it was 16 % the other 8%

er, yeah...
anandtech review, including power consumption:

http://www.anandtech.com/show/11278/amd-radeon-rx-580-rx-570-review/16

more like 30-50 depending on manufacturer and boost.

nothing so "complex" abt it

end of the day it is lowest cost per hash + best efficiency be it an ori or modded bios. no matter how it is tuned or adjusted, 480 will consume more power than the 470's.

simple, now show/tell me:

470 4gb vs 480 4gb perf vs watts so on and so forth according to list you listed out.

50-100W more is a RUBBISH comment & spreading FUD !

obviously i do have actual results mate as i am also sharing it with citronick live, i will also test SMOS shortly using the RX 5xx series. all i can say atm, the driver is pretty unstable. there are some new features too.

depends how "best" is categorized for a miner in terms of a kiddo making rubbish comments (2-3 mths ROI?) or in terms of a commercial/investment operations.

tbh, best is, least $ spent/invested for the best returns in shortest period of time, well that's for me for a start.

numbers NEVER lie.

OP what you are commenting are more applicable to you personally imo, not for the general public. it is in fact yeps with those ti's but ONLY for ZEC but with an AMD it can mine everything else including ZEC so in long run AMD is more worth to invest & i don't really need to know how much is the creator of the gpu is worth "x" billions but of course the more they are worth the better but that's not the point. AMD itself is worth quite a bit too especially with RYZEN.

i'd rather place my $/bet on ETH + everything else than just ZEC alone.

btw, it's on the move OP, chk your PM.

deleted

I don't delete and not save the  post.
I deleted because  deciding

between
 rx 470 4gb rx 480 4gb
 rx 470 8gb rx 480 8gb

rx 570 4gb rx 570 4gb
rx 570 8gb rx 580 8gb

nvidia 1060
nvidia 1070
nvidia 1080
nvidia 1080 ti

Is complex and varies miner to miner.

I can give examples  that anyone above is best or not best for a miner.


First case would be getting nvidia and no amd.

Why  you are taking a shot that Nvidia a 52 billion dollar company  reads and understands  they are the God of Zec mining.  So they say lets do a pump of the coin  to simply sell all our gear out.
This would be easy for them to do since Zec has a market cap of 79 million and Nvidia has a market cap of 52 billion.

If Nvidia did a prolonged pump  it would be cheap to do and they can do it.

Will they do it I have no fucking idea.

Second case like me you re about to enter summer  excess heat and higher power price.  Nvidia will save power which saves heat / cooling and power cost.  Truth simple but true

Third case 9 nvidia 1080 ti will do  9 x 650 = 5850h  at 1900 watts  three 3 card rigs with 750 or 850 watt evga p2's  Or  19/20 rx 480 8gb using  2900 watts that is 4 rigs with 1000 watt psu's   fact the amd could be at 2400 watts according to some with flashed cards but that is another pair of sleeves


So 3 reasons  why all 1080 ti's are your best choice. are above two are true if you are going into the summer facing heat/cooling  power and space issues.

3 3 card rigs vs 4 5 card rigs  

I can go down the list with every card I mentioned as each and every one has a case to be made for and against it.

I guy with 25 rigs say 100 to 150 cards  has different setup concerns then someone like me say 50 winter cards and 20 summer cards

The new 570/580 use about 30 watts more due to the higher voltage at the boost clocks

We typically under volt and under clock so that will have no effect on us.

Saying they us 50-100 watts more is spreading misinformation and incorrect.

Notice I said as the price drops...and a 480/8G card is going to be a bit more future proof and easier to resell when you have hit ROI in 3-4 months time.

I believe the 2nd hand market for 470/480 4G cards will be drive by people looking for absolute bargains, whereas a buyer for the 8G cards is willing to pay a premium

i might, but the price stays put (8gb RX 470 Nitros are still $250 in Microcenter+tax and similar at newegg). I don't know what is their economic model is, but cards seem to stay on the shelves with no price adjustment apart from rebates that take freakishly long time.

Grab yourself some 480 8G versions as the price drops

The new 580/570 series are ~3-10% quicker but use 30-60W more power.


Edit: To make power consumption figure more accurate

newegg has a bunch of 570/580, difficult to know yet which ones are good in price/performance.
are 4gb 580 or 570 viable going forward or 8gb is a must?

a little teaser . . .

i posted on other thread though https://bitcointalksearch.org/topic/m.18639847

Exactly   you know your limits and don't go past them.

My  mine a card for 40-60 days then sell it here in the marketplace has been a viable plan for me and for the community.

I make about 10% on a card. 
The buyer gets a 20-40% discount on the card.

Flashing a card  in my case does not make too much sense.
I have considered and talked with a few people that making flashed cards on order  as  service  but nothing has come about.

So  discouraging flashing cards  is not a set in stone thing for me.

flashing is pretty easy and safe when only doing memory straps. use a test bench computer (one card at a time), use a UPS, dont use  someone elses bios. do your own card, back up the original bios  giving it a full name (card manufacturer, model, mem amount and type. serial number) and back that original up several places. then just flash the memory straps. with eth you can gain 20% easy, at least on some amds

even if you brick a card you can (usually) blind flash it back, or use a good card to boot with the bricked card in the system (use an old pci card or cpu with igp) and flash it back.

of course this assumes the bricked card is still recognized in the system. im sure, depending on how bad the card is bricked, that doesnt always happen, thats why i only mess with straps.

I would only flash cards with a bios switch.

as in your example above.

I am anti flash due to the amount of bricked cards  that happen.

one reason for this is intentional bad info from various   people across the net.

Any 2 bios card  you

 you can try to flash.

Also Since I do early resale of cards having flashed ones are bad for business sales .  as flashed cards can be very flakey  they don't play well with other cards.

I would advocate flashing but  I have yet to cut a deal  with a flashing expert.  I would love to flash your cards for a fee  but I need a partner.  As I can not do the real work.

But if a guy helped me that knew what he was doing I would simply flash cards for a living at least from May 31st to Oct 1 since my power bills go up  during that time  cards flashing would be a nice way to do it.

I would love to have had an offer from someone.  but no one has that I would consider doing business with.

So I clock  threads and there have been over 100 I killed or screwed  up my  card flashing it threads.

Newegg 4% cashback

Personally on the amd 4xx cards, for eth it is a requirement.

How high you clock is up to you, I let mine live the easy life with low temps (55c, 25% fan).

Mod your own bios, so you know it will be compatible and make backups.

How do you get 4% cashback?

@philipma1957

I wonder why you are so anti-flash?
I haven't flashed any cards yet (so i was anti-flasher in practice), but currently considering it, especially Sapphire Nitros, which have two bioses.
Worst come to worst, i will mess up the silent bios, but can always switch back to the 2nd setting (default)
My thinking is-why not-it will give me at least a 20% extra on Nitro's with no money spend with eth difficulty already high and getting higher.

You really know how to convince people

I have reserves on the 200A panel, but not at specific circuits where I can mine.
I cannot mine in the middle of the living room or in the bedroom.
15A, derated to 13A can only do 1430W on 110V
15A, derated to 13A would do 2860W on 220V, exactly twice as much.
