damn 20 fans thats crazy.  i wonder what your electricity capacity is, over 200 amps ?  I just have a turbo fan type exhaust out the window, moves air really good.  if its at max, outside you can feel it 15 feet away.  gpu temps arent really lower much, but house temp is wayyyyyy lower.

i believe its where I have my rigs and how I built them.  I have them set up for looks with leds showing and everything is color coordinated on racks that looks real neat, but not optimal for air flow.  My first 16  rigs are real eye candy, but am learning the price I have to pay for a "cool" set up.  My new rigs I am building are designed for heat management and it takes one fan to keep them under control.  I run my 200 amp service at 220 amps with air fans keeping the breakers cool.  I am building a barn with 400 amp service to move them too so I can take the heat and the fire risk out of the basement.

Honest question here: do you guys think that your GPU's cause indoor pollution? I stay a lot in my room where my rig is setup and I feel that the air i am inhaling aint to good, any thoughts on this ?

The constant heat might make the air slightly less humid and a brand new rig may off gas some chemicals the first few hours/days of operation, but other than that I do not think running a miner is any worse than running any of the many other appliances we have in our homes. If anything, the air quality is probably cleaner for me, especially in the winter time, as I can now leave windows cracked open for fresh air pretty much year round. There are a couple of months in the peak summer I need to close up and run the A/C, but I usually shutdown most of my in-house rigs then and/or move them out to the garage. The garage is another story however, summer time it is a virtual oven and I need constant air-flow or bad things will happen. Wink

I just started mining so have not yet to deal with the summer heat- how do you guys deal with this issue? I feel like my  room is going to get hot even though im in the basement. I have two fans but thats barely enough right now, how does everyone deal with cooling their gear?

Good airflow and lots of it. Does your basement have any windows, even those small ones by the ceiling? If so, you might want to try and setup a fan in the window to try and exhaust some of that hot air outside.

If you only have one rig, a larger basement might be able to dissipate the heat to some extent. It may get warm but not excessively hot. With multiple rigs and/or a more confined space, you will definitely need to look into getting some airflow into and out of the space.

I have 21 rigs in my basement and they generate a lot of heat.  The key is the 20 fans that I use to direct lots of air flow through my rigs and out the 4 basement windows.  When my fans trip out, my house rises to 90+ degrees fast.  I also run all my cards at 50% fanmin to keep the air flow higher.  I don't care if the fans wear out as long as they still protect my cards.  Fans are way cheaper than the cards.  The prior post said it right, good airflow and lots of it.  You will not win the battle with air-conditioning.  Its all about moving the heat away from the units in a organized manner.

I have  40 rigs in mybasement lol with only one window fan , right now its still brininging in cooler air from outside, around may/june when it warms up i'll flip it to exhaust mode

Can we trade basements?  I like your results alot better.  Mine makes me sweat 5 lbs for every hour I spend down here......

Hi people, first sorry for my bad english, my problem is that i buy 4 saphire nitro (no plus) RX480 8GB, and i think i did a very bad buy becouse this model https://www.amazon.com/gp/product/B06VSWDK2H/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1  it has only 1750 mhz of memory clock and i think that it dosent have doble bios option. I buyed becouse i did not know that there where 3 diferents models of nitros... my question is, how much less hashrate will i have with claymores miner? and does standart bios mod for nitro+ work in this version or do i need a different one?

PD: I read that peoples gpus are dying for using dual miner ether/+ and for mod the bios, i do not want to happen to me, does it really damaged your card to mod the bios and do dual coin mine?

- Its not a BAD card. Its is a cheap card. This is why you chose it in the first place. So you already saved some money. Why regret now?
- You still can mod Bios. But modify it yourself rather than use someonelse's. Follow step by step instructions bit by bit (can be easily found via google).
- You should ask questions on the forums where you read "that peoples gpus are dying for using dual miner". I did not see anything like that in this thread.

I bought 6 of these cards because I did not notice they were not Nitro+ cards, and I could not return them once I got them, so I run them at 24 MH/s on ETH and 1000 MH/s on DCR.  Have you found a good way to mod them to get more, because everything I tried just made these pieces of crap trip out?  So I use Claymore's program to adjust the voltage and clocks down and get what I can until the cards die.  I would love to find a set up that is stable and delivers better performance.


These cards do not require a special treatment. Deal with them as other people deal with their 480 4GB.

What are your current settings? What have you tried? What settings do crap out?

Can you do BIOS mod with those non + cards?

You have to be careful when mod'ing these cards because they do not have the dual bios mode, so you can brick it if your not careful.  I run them at 950mV mem, 950 mV core, 1220/1950 and they run stable at 24 mh/s.  Suggestions from someone more skilled?  Tried to mod the bios on  one and I was unsuccessful and I barely got the original bios back on it to get it going again.

@Mr. Claymore,

Something I want you to look at, when devfee starts while I mine ETC it try's to connect to us1.ethermine.org:4444 that port does not work and it keeps the devfee running longer, can you maybe change it to port 14444 that one works because I'm using it and also can't get 4444 port to work.

thanks

actually it collects some dust so less dust you inhale - it cleans a bit

actually, I agree, having just four GPUs in my office made air stale, but here is a solution (greatly improved my perception of air quality):
https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-True/dp/B00BTKAPUU
it is silent in eco mode (most of the time when on auto) and you can periodically switch the air ionizer on to make it feel even fresher.

Hey Claymore my Rx 480 4GB G1 Gaming Gigabyte keeps crashing after a few hours and it messes up the internet connection disconnecting it and crashes the driver allot. I have to restart PC all the time.

I just hope you get that fixed in the next update.

Thank you.

On Ubuntu 16.04 with  
amdgpu-pro-17.10-401251 (catalys 15 don't install. v16 works but 17 seems better)
and
AMD-APP-SDK-v3.0.130.136-GA-linux64 installed...
I use a RX470

all goes fine but at start of ethdcrminer64 v9.1 I have
"AMD ADL library not found."
and
AMDAPPSDKROOT=/opt/AMDAPPSDK-3.0
environment variable set in the systemd service

I don't know if it is a problem.
-asm 2 does not improve anything over -asm 1
I have temp and fan status
"GPU0 t=59C fan=67%"

I want to make all perfect, maybe I'm searching for inexistent problems...


gpu-pro does not support amd adl, so it's ok. -asm 2 has same speed as -asm 1 for most cards, it depends on GPU model, so it's ok. -asm 2 was added mostly for overclocked Tonga and Polaris cards and only for ETH-only mode. On these cards you can have best speed on -dcri 1, -asm 2 moves -dcri scale for these cards so you can try to find speed peak at larger -dcri values.

@claymore

Hey Claymore, it looks like you prioritized who uses dual mode in these latest updates. For me that mine only ETH, I still use version 8.1 that continues faster (briefly). Do you have any plans to improve performance for eth only?

You should mention that 8.1 is faster for your cards. For some other cards v9 is faster. What GPU do you have? what -dcri value is the best in v9?

Hi Guy's , as I can see there is still issues with fluctuating hashrates, this below was one of my earlier posts,

 

Mining ETH+DCR ( ETH = 60.6 MH/s ) ( DCR = 1757.xx MH/s )
Equipment = 2 x Sapphire RX480 Nitro+ OC Dual UIFE Bios ( YES!!! Modded )
Afterburner V4.3.0
Claymore V9.1

Batch file is as follow.

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -dcri 29 -epool daggerhashimoto.eu.nicehash.com:3353 -ewal BTC-ADDRESS.Worker -epsw x -esm 3 -allpools 1 -estale 0 -dbg -1 -dpool decred.eu.nicehash.com:3354 -dwal BTC-ADDRESS.Worker -dpsw x -asm 1
pause

So I have had the same issue with fluctuating hash rate eth 30.5 MH/s to 23 MH/s but as I have read through the posts I have tried using -dcri and by slowly increasing and decreasing as you monitor on the scope of afterburner to find the smoothest line on your wattage usage, "I could get it better but than I loos some of my hashes on ETH",  I got to -dcri 29 and that was the best setting for my setup. on ETH-ONLY MODE - dcri 4 was the best.

I does not remove the fluctuation it only makes it less fluctuating.

Hello all,

i have sapphire rx480 nitro without + SKU 11260-16 which driver should i install, i treid many but on all drivers when i reis memory to 2250 with msi afterburner its crash display disconect, or is there any modded bios? for this model.

Best regards
2250 is quite high. It is too much... lower it.
