what drivers is for this cards?

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.

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.


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?

Where do I find reboot.bash?

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

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.

@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

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.

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.
