try gui miner alpha for srypth coin (in this case litecoin)

good pools are (coinotron.com / www.litecoinpool.org) hashrate may depends even of pool


let ratio from gpu /memory be 0.69-0.73

try gpu between 1000-1050   and video ram 1000-1300

driver 13.1

try this (my personal settings)


worksize 256
vectors 1
aggression 19
threads_per_gpu 1
sharethreads 32
lookup_gap 2
gpu_thread_concurrency 16384


i used this for 7950 x 4 , if there is still low hash rate if you need help contact me thrue skype (dejan.arandjelovic86 ) best with hashrate

try other pool...or restart your pc so can driver can load again...

how many cards you have on that psu?and what are you mining?

on many pool there is no fee to take your coins

example coinotron if you want to withdraw below 10 fee is 0.1ltc if is more then 10ltc fee is 0.

you want to people mine on your pool...


if you already had some ltc from your pocket my advice is bonus for users that mine 24/7 ...


bonus for 7 days,14 days ... 30 days and soo on...

few questions for you when you power your rig is third card fan working or not?
how is connected to psu?with 1x8pin and 1x6pin pci e or molex adapters?
did you checked solo that card is working fan and card ?

one 7970 on LTC or scrypth depends on gpu/vram clock can spend even 350w
if you plan scrypth mining max 5  cards for lepa 1600 with undervolted...
before you buy cards check if there arent voltage locked ...new series with BE -BOOST EDITION most are locked..

use ARCTIC MX 4 for gpu's not Silver...

what was temp outside before that and what is now?


try some fans few od 12cm to put behind the cards ...

also the cards are  too near each one ...

try to undervolt them...

welcome to forum...

if you are from china try to get avalon miner od avalon chips made by TSCM

dude that is OK hashrate for that a know that 7990 i dual 7970 taxiti xt...on that clock that is best score...

like logo and idea...to support gpu miners ...hope to be bronse value ...or even silver like litecoin

what clock are your gpu's?if your video ram is dowclocked that is reason getting 250kh/s


you must know that scrypt mining (alt coins) are 1000 lower speed and it is in KH/s
scrypt mining is also using your v ram...if your ram is downclocked that is bad for mining speed...
so gpu/mem ratio is about 0.7 that means if your gpus is on 1000mhz your video ram clock has to be almost 1500mhz if you want good hashing rate power...

try gpu on 1000-1000mhz ram 1375-1500clocks to see what value you get?

and what program /pool/coin your are using ?



example (ati 6970 in sha 256 -bitcoin has speed 400mhs/ but in scrypt gets almost 495kh/s )
if you have some questions and need help skype me...
