Its not fast but its cool.  I can up the mem a bit but it crashes.  I can lower the voltage a bit but it crashes.  I can lower core clock but hashrate degrades a lot.  I wonder how many watts, 120v, on 80+ bronze psu 1000GQ, it uses at the wall.  Any guesses before I measure ?  any ideas to improve, this rig is a bit weird.  edit: its the asus 5700 oc evo dual.  I wouldnt say very stable but were 340 in usd equivalent so very cheap to me

Those cards were terrible for me.  of 38-40 amd 5000 series cards I only had to return 1 card so far.  asus dual 5700 xt

your memory temps are causing it to throttle and crash. I have two of these cards and have replaced thermal pads, added pads to back plate, increased  mounting pressure, but nothing works. The only way to make these cards work is to blast the fans (i have mine at 75%) and keep them as far apart as possible.

[fr4nkthetank]

ill do that.  thanks.  I was thinking about thermal pads but i'll push the fans hard.

[geck]

from your screenshot, you could reduce your gpu voltage to 740mV and run the core much lower.
With timing mods, and mem at 1800, core can be as low as 1250 before hashrate starts taking a hit.
It looks like you didn't do any timing mods, so you could run the core at 1150-1200

[fr4nkthetank]

Wow these cards really have bad memory cooling, as you said geck nothing works to cool it.  But improved results after tweaking a bit.  im happy with it, cant lower core much or crash, higher mem crashes due to temps and gpuz 77w is good, probably 130-140watts wall, I will check.

Sometimes breakers are just slowly cooking

Yeah if you are just under and there is a small voltage drop say 120 to 110  or 240 to 210 breakers pop.

and when they pop, they are dead...forever, toasted.

my personal solution is increase the breaker amp capacity.

for example, if you are maxed out and breaker keeps popping at 80A increase it to 100A, only do this if you know what you are doing, just don't add more load just because it is "not popping anymore"

my solution is not in the electrical code, codes are there to guide and make things as fool proof as possible. just think about a breaker, it is just a switch (contact points connect and disconnect--> this is the weak point), there is no way it can match the electrical capacity of a solid (no connect and disconnect) wire, good high quality more expensive wires will perform. I have not tested all the breakers and brands but this is from experience.

BTW LOL at ETH mining profits, the 3080's are starting to look cheap hehehehe

well I was just thinking this.

wait i'm not done yet hehe..



12A for each extension wires x 8 = 96A, you'll never reach 2500w load for extension wires, why? they have breakers and fuses too (if this fail solder a solid copper) besides two (3x gpus to 4xgpu 3080 rigs) will never reach 2500w. example: 300w per card x 8 = 2400w... my favorite x3 card is 1800w only (I used 300w per card means i added the whole system to make things easier to digest/understand)........this also means you are not going to reach 96A for wire and 100A for main breaker, this also means that 80A breaker will slowly cook and pop from time to time, same thing with those 20A breakers.

300w per card analogy means you can also setup dense gpu rigs, 3080 or 3090 top of the line power hogs hehe

the key is outlet management.

maxing out wires means you are taking responsibility off from the breakers to you, just like you login in an operating system as "admin". so "know your wires"

my drawing is simply the "essence" people can figure out their own wiring scenario from this basic guide/principle.

what i mean by 80A to 100A and 20A to 30A is replacing 80 by 100 and 20 by 30 to max out the wire and not have the trouble of popping and toasting breakers.

electrical code says #4 is 70A and #12 is 20A breaker, LOL of course low quality wires will only do as low as 65A-70A, that's why like i said, it is to make things as fool proof as possible. good quality #4 wire can do 95A.....same thing with the #12

do not do this don't use a high quality #4 and hope it can handle 80 amps on a 100 secondary box.

and don't use 12 gauge on 30 amp breakers. even if it is high quality.

this is not code in usa  so I have to warn you.

codes would be #2 for the 100 amp breaker sub box and  10gauge for 30 amp outlets

I ran a #6 from my main breaker to a 2 circuit sub panel and 10 gauge to 2 outlets.

I used a 50 amp 240 volt breaker in the main box to a pair of 30 amp breakers in the sub panel.

Lastly I attached some high quality 20 mp voltage regulator to each  circuit .

so 50 amp to 2x 30 amp  to 2x 20 amp

yeah it limits my garage to 32amp of 240 on spilt on 2 protected circuits but I am okay with this.

My garage gets really fucking hot if I run 30amp x 240 = 7200 watts of power 24/7/365 unless it is 40f or lower

what I mean by "can do" is "wire rating" not "continuous load", thanks for pointing that out, it can be misleading.

I forgot it was a 70A breaker to 100A change...the breaker was in storage for years so if forgot hehe

https://www.cerrowire.com/products/resources/tables-calculators/ampacity-charts/

see the link there is a 65A to 95A types for #4 wire and 20A to 30A for #12

no worries load will only have 65A-70A max for continuous load.

notice the standard consumer/end user outlet of 15A? and the off the shelves/commodity extension cords with 2500w rating (12A at around 220V)?....that is 80% max load at 20% allowance.

even the extension cords should be used at max load of 1800w - 2000w max for continuous load, 2500w is also just a "rating". notice at 8 outlets of 9.5A load each is 76A (2000w load at 210v-->worse case scenario of voltage drop)...at 1800w per outlet you are safe.

two gpu rigs with 1300w PSU each at around 50% load for maximum efficiency, that's only 1300watts for two rigs, if you run at less efficient then you can pull up to 700watts more for both rigs (1800w-2000w max load for extension cords).

same thing applies at the 95A wire at 80% load is 76A, so 70A is safe  

but then some people think they know what they are doing even if they do not...so if people start asking me questions, the answer: "follow the electrical codes!" LOL

Anyone mining ETC and converting it to ETH?

ETH diff is now at ATH

Yeah but price is over 600 and the 5700xt or the 3080 are efficient so for now eth is still worth mining.

Bitcoin at $19,000.

Just think, it only has to go up $30,000 more and I can turn on the Avalon's I just had to have!

49000 a coin to reach profits.

what is your power cost?

[Toughit]

Electricity is at $.155/kw.

Avalon 720's

I even have a new Whatminer M3 that was not profitable to run by the time I got it.

[favebook]

Avalon 720's

I even have a new Whatminer M3 that was not profitable to run by the time I got it.

Are those (Avalon 720s) the one on 16nm of around 900W with 6TH/s?

If yes, they are quite old and I'd rather sell that one to someone who has free or almost free electricity.

I'd do same with M3 as well, not sure how much you waited for those units, but they were quite profitable back in their days IIRC.

Nowadays, they are as useful as usb bitcoin miners.

[philipma1957]

the Avalon can be quiet and is a decent space heater.

[adaseb]

The only miner I got left is an Antminer S3 that I decided to keep for my Bitcoin Mining museum. Decided to plug in the numbers and see what price BTC needs to hit to break-even with $0.10 power costs. The answer is $246,000 BTCUSD assuming difficulty stays constant which obviously it won't.

I remember a few years back for fun, I ran it on the ck solo pool hoping to hit a block and no dice. Didn't even come close by the amount of largest shares that I found. Ran it for maybe 9 months before calling it quits. Wonder if it eventually would of found a block... probably not. According to that ck solo pool thread on bitcointalk, I don't think an S3 ever found a block, most recent was maybe an Antminer S5.

[philipma1957]

So I am getting a third card from minefarmbuy.com it is an evga 3080

first two do 92-95 mh solid no issues.

They have a bigger markup now that the amd 6800xt have launched and show only 60-70 mh.

i think he has a preorder for the sapphire 6800xt

should ship on dec 20.

he has a smaller markup and free shipping for them.

695 vs 649

if you really want an amd it is a decent price.

I paid 856 for my evga.

it lists at 769 but between all the deals with my cc and paypal. my cost for these cards

was 2x856= 1712-75 or 1637 for two. that is 818 each free shipping and 90 days to pay no interest.

1 card was 856.  180 days to pay not interest.

If evga had them in stock 769 + 54 tax = 823 six months to pay

hi phill...take it you mining ether with these nvidia?  can understand if its a "density/space issue but the price of these newer gen amd/nvidia gpu's against say 5700's still dont make economic sense from current eth earnings/revenue pov

[philipma1957]

hi phill...take it you mining ether with these nvidia?  can understand if its a "density/space issue but the price of these newer gen amd/nvidia gpu's against say 5700's still dont make economic sense from current eth earnings/revenue pov

the nvidia 3080 makes some sense. 

 



 

the 6800xt does not unless it improves with more software.


a 3080 costing  813 and doing 93 mh. and 240 watts

is very close to 2 power color red dragon  5700 xt costing 831 and doing 102 mh at 212 watts

if I have this board.

https://www.ebay.com/itm/Onda-B250-D8P-D4-Ver-1-00-12-GPU-Mining-Motherboard/143840755013?


it costs  210 and does 4 cards next to  perfection

so 4x 93 = 372

or 4x 51 = 204


I need more boards more space and  have to pay more to simpleminer.

  6 boards gives 2232gh for the 3080
10 boards gives 2040gh for the 5700xt

so   4 x 210 = 840
and 8 x12 =     96 a year less to simpleminer

I have reached my space limits so I have to consider density.

I am selling off all the older nvidia and replace with nvidia 3080 card.

3 blower 1080ti's

8 hybrid 1080ti's 5 are msi/corsair 3 are evga

2 evga 1660ti's

1 evga 1660

1 zotac 1660ti


this is 15 slots or 4 boards. gives me 540 gh.

 I can replace with six 3080s. 2 boards

or 11 amd 5700xt.   3 boards

I have the boards

so I would save 24 a year to simple miner

6 x   3080 at 813 = 4878.     558 hash.     1434 software watts
11 x 5700xt at 415 = 4565.   561 hash.    1111 software watts

close enough fo me to go with the 3080's


my issue in Clifton Is not cooling or watts.

I can do 200kwatts  an hour
I only am doing 120kwatts

but space is lacking.

[digital$]

ok, yes.  understand your situation, thought it might be "space/density" criteria.  good luck and lets keep on mining!!
