Extremely low hash rates, help! *will donate 1LTC to whoever gets me out of this mess*

[VelocitySpeed]

Hi all, i have 3 r9 280x and whenever i mine with only 1 card, my Hashes look like: http://i.imgur.com/aJpXBB5.png?1 .. but whenever i mine with 2 cards, my hashes for each worker is 300 each! almost like my video cards decided to be lazy and split the work for the same result. Can anyone please help ? im willing to donate my first LTC to whoever can successfully help me out!

 

ps: https://litecoin.info/Mining_hardware_comparison i searched my current thread concurrency on this site, and iam currently using 20992 . It only seems to give me 600 hashes with 1 worker, it is extremely irritating.

Did you change your drop down to 0-1 instead of 0-0?

[MikkoP]

Don't use the SLI bridges. Create a new worker for each GPU and run three instances of the GUIMiner. Also make sure you use a different GPU for each worker in GUIMiner.

[AK0490]

Set guiminer to low intensity, 7970/280x work much better there. Also be sure to disable crossfire.

[MikeTz]

Maybe put 2 GPU threads rather than one and don't use the CF bridge

[kizoku_95]

use cg miner.

and set up a different worker for each card and disable crossfirex

Im sorry, i don't know what your refering to, what drop down is this?

I have a SLI bridge installed, but my crossfire/SLI is disabled, and i do have 3 intansces of guiminer, it's just that the 3 cards become lazy when i mine with more than 1, and my end result is still 600-700 hashes whether its 1 or 3 GPU's =(

 

Set guiminer to low intensity, 7970/280x work much better there. Also be sure to disable crossfire.

I lowered it to 13 intensity about 2hours ago already and it's still the same.

This situation is frustrating for me, so i genuinely think that whoever can get me out of this crap hole deserves the first LTC i was able to accumulate 2 days ago.

 

Maybe put 2 GPU threads rather than one and don't use the CF bridge

my GPU threads is 2 on each worker tab now, and my crossfire is disabled. Should i just remove the stupid CF bridge even though i disabled it ?

 

use cg miner.

and set up a different worker for each card and disable crossfirex

I've tried to set that up and theres always problems, i find guiminer so much easier, I will look more into CGminer soon though.

[Judahnator]

i always use cgminer. creat a .bat file  in the same folder as cgminer, and put the text in it:

 

"cgminer.exe" --scrypt -u <user> -p <password> -o <pool address:port> --gpu-platform 0 -d <0-2> -w 8192 -I 13 -g 1

 

see if that works for you. you can run a separate instance of cgminer for each card changing the -d value, or you can do all three but i will have to lookup how to do that.

[MikkoP]

cgminer.exe --scrypt -o stratum+tcp://world.wemineltc.com:3335 -u USERNAME -p PASSWORD -I 13

 

I use those settings for mining on R9 280X and I get stable 620 khash/s.

Go here and download 3.7.2 http://ck.kolivas.org/apps/cgminer/3.7/

 

Open notepad and paste this into it:

setx GPU_MAX_ALLOC_PERCENT 100

cgminer.exe --scrypt -o (your server) -u (your username) -p(your password) --thread-concurrency 8192,8192,8192  --intensity 13,13,13 --worksize 256,256,256 

 

Save it as (filename).bat

 

This will run all your cards at the same time, once stable you can then change your clock speeds to find what works best for you.

[Godlygamer23]

You mean Crossfire bridges.

This: http://puu.sh/5LkNI.png You need to make 3 tabs: http://puu.sh/5LkPs.png and each one must be on a different device. i.e 0-0; 0-1; 0-2

How do i change the clock speed? is that the thread concurrency? lastly, with this, i only need 1 worker correct? im going to try this in a bit after my im done taking my final.

oh yes, i have 3 tabs, 1 tab per video card. Though they all have [0-0] Tahiti for device, should i change that?

[AK0490]

How do i change the clock speed? is that the thread concurrency? lastly, with this, i only need 1 worker correct? im going to try this in 2hours after my final.

Add this to your bat file to set your clock speeds --gpu-engine 1050,1050,1050 --gpu-memclock 1500,1500,1500

 

With this  all your cards are under the same worker.

 

If you wanted to split things up and run a seperate .bat for each card you will add -d 0 to the file for the first card, -d 1 for the second card and so on

 

. Example below:

 

setx GPU_MAX_ALLOC_PERCENT 100

cgminer.exe --scrypt -o netcodepool.org:3333 -u AK0490.1 -p x -d 0--thread-concurrency 8192 --no-submit-stale --intensity 13 --worksize 256 -g 2 --gpu-engine 1046 --gpu-memclock 1500

 

setx GPU_MAX_ALLOC_PERCENT 100

cgminer.exe --scrypt -o netcodepool.org:3333 -u AK0490.1 -p x -d 1 --thread-concurrency 8192 --no-submit-stale --intensity 13 --worksize 256 -g 2 --gpu-engine 1046 --gpu-memclock 1500

 

To run all the card in one .bat you do as I posted earlier, place commas and list the settings multiple times.

 

cgminer.exe --scrypt -o (your server) -u (your username) -p(your password) --thread-concurrency 8192,8192,8192  --intensity 13,13,13 --worksize 256,256,256

Ok i did

setx GPU_MAX_ALLOC_PERCENT 100

cgminer.exe --scrypt -o ltc.give-me-coins.com -u (username) -p 123 --thread-concurrency 8192,8192,8192 --intensity 13,13,13 --worksize 256,256,256 --gpu-engine 1050,1050,1050 --gpu-memclock 1500,1500,1500

 

But it seems to be stuck at 500 per card even wit the gpu engine settings, am i doing something wrong?

[AK0490]

You just need to tweak your settings more. Try setting your core clock at 1080. So cards at 1080/1500. Also, try adding -g 2

 

For many more settings to try check out  https://litecoin.info/Mining_hardware_comparison and the.bat cave http://forum.netcodepool.org/forum/showthread.php?tid=641&pid=4237#pid4237

[VelocitySpeed]

Thanks AK0490! you've taken me out of this hell hole, what is your LTC adress or paypal email? i will send something after class, which i leave for in 7mins.

 

ps: putting -g 2 did the trick !

[MikkoP]

You mean Crossfire bridges.

 

Yea..

[Aleppi]

Do not use the CF bridge

[LoneGun]

Do not use the CF bridge

 

Why? I've tried it with or without CF bridges, doesn't matter at all! As long as you turn off CF in Catalyst. It's an urban myth that won't die.

I will just clearify this, so that you may use GUI miner, which I personally prefer For each tab you need to swap the GPU: Tab1: 0-0 Tahiti Tab2: 0-1 Tahiti Tab3:0-2 Tahiti

Also, my 7970 seems ti like 16 or 18 as I and 1 thread

I agree, as long as you do not CF it in the drivers, the cables are not active...
