i wish i knew how it worked for you, doesnt work for me but you should base worksize on your gpu. is your gpu 512 bit? then put it to 512

also try higher thread concurrency

try going up by multiples of 64, starting from 8192.

for me, mining on guiminer with 1 gpu thread actually helped and it mined better, dont know why.

You could try using xintensity. Also for whatever reason 8193 tends to work alot better for tc.

512 worksize still creates 256 bin files. 256 is current max unless somethings changed recently.

You can also with the newest sgminer use zuikkis kernal which tends to work better. Not at my pc otherwise id copy the code

I just switched from 3.7.2 to the 3.7.3 and my hash rate went from 450 kh/s to 490 per card. Is this normal? I dont want to be killing my cards somehow. Am using gigabyte 270's (non x). miner has been running for almost 2 hours with no hardware errors.

These are my config and bat files.


cgminer version 3.7.3
config file R9 270

"xintensity" : "4",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "5121",
"temp-cutoff" : "80",
"expiry" : "1",
"failover-only" : true,
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"gpu-threads" : "2



3.7.2 .bat file
-w 256 --gpu-engine 1120 --gpu-memclock 1500 -I 18 -g 1 --thread-concurrency 12000 --temp-cutoff 90 --temp-overheat 85 --no-submit-stale

I have only one pool account at wemineltc.com.

After 19 hours of mining check this out ;

When use this : Warning: Spoiler! (Click to show)

I have error - "Need to specify at least one pool server"...

Please, help ?

i havent seen that global.wemineltc server, maybe thats why? and it says "stratum authentication failed"

so im pretty sure it has to do with the links you supplied in the conf file or the bat file

just use

stratum+tcp://megahash.wemineltc.com
for backup
stratum+tcp://freedom.wemineltc.com

or if you are american theres 2 more servers available but thats it
USA Server (VARDIFF): stratum+tcp://usa.wemineltc.com
USA Port 80 Server (VARDIFF): stratum+tcp://usa.wemineltc.com


if that helps you out send me some ltc smile.gif or + rep cuz your hashrate very low, gonna take you some good months to make a coin, id rather buy bitcoin and use that to buy litecoin since you can only buy bitcoin in order to buy litecoin....jealoussmiley.gif

I have seen the optimized scrypt kernel but I am confused because when I look at my .bin files that were created, they start with cklovas and following 130511Tahitiglg2tc8192w256l4.bin, I am running on 64 bit and now 32 bit, why is it ending at l4 instead of l8?

Thanks for your help, you asked nicely and I will answer you politely smile.gif
I knew that the server is not configured well, I was just wondering why and my friend who is nothing asked of me, he found one little mistake : comma / notch wink.gif

Hi man, i am using this setting from you, and it kind work:

]
,
"xintensity" : "4",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "8193",
"temp-cutoff" : "90",
"expiry" : "1",
"failover-only" : true,
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"device" : "0",
"gpu-threads" : "2"
}

but i have on 1 PC 1 290 VTX and 290X ASUS, and when i get this conf i only get about 700kh/s, i am using like u say 2 different .bat and .config for GPU bcs then i dont get driver crash, bcs when using everything else i get crash driver, and i have one more gpu 290X but again when using them 3 together get driver crash. So what i need to change to get little higher kh/s? I am using MBO BTC Asrock, Windows 8.1 and ATI 13.12 drivers. Thank you

I dont have either to test personally but usually those settings only work for 270x or lower.

From what i hear 290 dont do well with 2 threads. Im sure theres a magic number but noones found it yet. Usually u can push over 900kh with 1 thread at higher tc and intensity.
