Куплю BTC-E code или биткоины по курсу btc-e на 2000 USD. Желательно личная встреча в Киеве, предложения в личку.

Он для запуска требует много памяти, потом при работе меньше занято.
про память там требования такие:
На каждую карту на каждые 8000 thread -concurrencies требуется 500MB
То есть на одну карту с 24 000 thread -concurrencies будет требоваться 1500MB
Может быть поможет закрыть все посторонние программы.
Тоже так думал, пока не запустил ферму с тремя 7950, tc24000, 2gb ram:) |

Hello. I'm using Xubuntu and cgminer 2.11.4 with 3x 7950. Help me please how can i control voltages from console if it's possible? I try do it with cgminer but no effect. Thanks.

Привет! Куплю 3 x16-x16, и 6 x1-x16 или x1-x1. Желательно с возможностью доставки в Украину-Киев, если не найду такой вариант, могу забрать в Москве или СПБ. Жду предложений.

I try with your confgs. 313 khash/s per device. Why you decrease stock engine and memory clocks?
Through many hours of messing about one day those are the settings I found give me the max hash rate possible. I did this on every card I have and every one without exception gives more hashes if you lower the gpu engine below stock speeds and raise the memory speed once you get to a certain point on the memory nothing above it will give you more speed in fact usually decreases it. You use --auto-gpu option. This option only decrease engine? No it automatically manages the gpu engine if it gets above the --temp-target you set the --auto-fan does the fan speed to keep it below the --temp-target. The second set of my posting is the speed settings I set for ltc mining the --od-setclocks lines. Thx for answers. What version of SDK you use? I cant understand why my hashrate is so low. |

Hello again. Some info about my rig: Xubuntu Live (on 4 gb flash usb); 4 GB RAM; HD 6950 unlocked @6970; HD 6970 I build cgminer with --enable-cpumining & --enable-scrypt. When i start cgminer i receive error message:

Before i export GPU_MAX_ALLOC_PERCENT=100 & GPU_USE_SYNC_OBJECTS=1. Maybe trouble with freespace on my usb flash drive. Without --thread-concurrency option maximum hashrate about 340 on each gpu khash/s. Try something like I used in a machine with two 6950s flashed to 70s.
cat ltc.sh
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export DISPLAY=:0
~/cgminer --scrypt --worksize 256,256 --thread-concurrency 7040,7040 --vectors 4,4 --gpu-threads 2 -I 18,18 -g 1 --auto-fan --auto-gpu --temp-target 81
And the card speeds.
cat vset.sh
DISPLAY=:0 aticonfig --od-enable --adapter=all
DISPLAY=:0 aticonfig --od-setclocks=770,1230 --adapter=0
DISPLAY=:0 aticonfig --od-setclocks=770,1230 --adapter=1
DISPLAY=:0 aticonfig --odgc --adapter=all
This gives me 410kh/s per card, leave out the --shaders like I do only one of them is needed so it is it or the --thread-concurrency option not both. I try with your confgs. 313 khash/s per device. Why you decrease stock engine and memory clocks? |

Where did you download the binary from?
cgminer needs to be compiled with CPU & scrypt support for it to work with litecoin.
Thank for your answer. I build cgminer without necessary options for cpu mining. |

Hello. I try to mine litecoin with cgminer (v. 2.7.5, xubuntu 12.04, sdk 2.7). But when i try to start it: ./cgminer --scrypt -o xxx -u xxx -p xxx
[2012-09-23 23:56:42] ./cgminer: --scrypt: unrecognized option
What í'm doing wrong? Bitcoin mining work fine. Even in cgminer --help i cant find option --scrypt. Thx. |
