а смысл если ос больше не тянет ? а если уж портов родных мало то тогда есть смысл двухголовые взять )
а если на одной машине поднять виртуалок? А на двухголовые лимит не в два раза меньше? |

Link for this theme in russian https://bitcointalk.org/index.php?topic=68839.0Here is some graphs with correlation of memory clock and performance in MH/s. All graphs available here: http://ocakypa.dyndns.biz/miner/ And script to produce thathttp://pastebin.com/qkCFBEUrrequires screenCopy it into cgminer's directory. Make sure you change values on config section. Results will appear in directory defined in "results" variable. Make sure it writable. Cgminer always include default config, so rename it or remove. Config to run cgminer in "cgminer_config_path" var. Here is my config for device #0 (test0.conf) {
"pools" : [
{
"url" : "http://pit.deepbit.net:8332",
"user" : "XXX",
"pass" : "XXX"
}
],
"intensity" : "9",
"gpu-engine" : "0-930",
"gpu-fan" : "0-85",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"auto-fan" : true,
"expiry" : "120",
"gpu-threads" : "2",
"log" : "5",
"no-restart" : true,
"queue" : "1",

"temp-hysteresis" : "3",
"api-listen" : true,
"donation" : "0.00",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
sometimes X server hangs, in this case script will create file "reboot_required" in current dir, so you could use ither script to reboot automatically First parameter is device number to run tests on. It 0 by default. Also run another instances of cgminer befor running this script, because it will overwrite another GPU clock values. Sometimes identical GPUs with same clocks produce different MH/s, so be careful comparing results from different GPU. Results will appear in subfolders in json files. I wrote php script that draw graphs. http://dl.dropbox.com/u/569082/cgminer-tester.zip Put it into webserver webroot somewere, tests put in tests dir inside. UPD0: script on pastebinUPD1: upd scriptUPD2: picture changed |

Всем привет поделитесь информацией ...
Кому сколько по времени шли райзеры, заказал 22 января с ебея до сих пор жду,
через неделю после заказал с китая..тоже жду, и в понедельник обещают отослать с украины....
Так а по треку не видно где застряли? |

I would love to see an expanded version of this that goes down to 100 (or lower) memclock using latest version of cgminer, latest drivers, and SDK 2.1.
Here is some tests  You sir, are full of awesome. Will we be able to see the other test results soon? Do you have a 5870 to test with? @tenzor Were you running this on linux? And are you willing to share the script you used to generate these results? Here is it http://pastebin.com/gpFDyXefrequires screenCopy it into cgminer's directory. Make sure you change values on config section. Results will appear in directory defined in "results" variable. Make sure it writable. Cgminer always include default config, so rename it or remove.

Currently I am testing 5850 all kernels 150-300 memclock. I expect results will be ready after 3 days |

About graphs, what I did recently. It seems to be wrong, because I ran 4 instances of cgminer with small interval and small memclock diff. And each next cgminer process overrides memclock for all GPUs even if you use -d 0 So, this does not work ./cgminer -d0 --remove-disabled --gpu-memclock=305 this work ./cgminer -d0 --remove-disabled --gpu-memclock=305,0,0,0 |

Here is some tests  |

I haven't been able to reliably run my 6770 above 960.
Ok. @960/300 I have 220-225 cgminer 2.2.6 Edit: Summary: @960/300 = 220-225 @1000/300 = around 230 cgminer 2.2.6 -I 9 -v 2 -w 256 -k phatk SDK 2.4, ubuntu, catalyst 11.6 |

My 6770 runs waaaaaaaaaaaaaaaaay faster with the diablo kernel.
I was reliably getting around 185-190 Mhash/sec with poclbm. Now it's reliably around 202 with diablo. Really noice!
Hmm. my 6770 runs around 230 Nhash/sec with phatk at 1030/300 clocks. -v2 -w256 |

Дело темное, это понятно. Но разве нельзя камушек опросить через какой-нибудь сервисный интерфейс?
Тут тоже непонятно ничего с CIS.FPGA...
|
|
|
|
поподробней чтоль опишите что как собираетесь делать.. Эти ваши баттерфляи жрут в 2 раза больше чем спартановские платы.
И стоят в два раза дешевле. А у нас не такое и дорогое электричество. |
|
|
|
|
ну на 15% больше мегашняг за ту же стоимость, в сравнении с CIS.FPGA, предполагая его стоимость в $180
|
|
|
|
|
По прикидкам они по 130 ватт жрут каждая, плюс мать-проц-остальное с запасом (!) жрет 200. Итого туда 850ку, учитывая КПД 85%.
|
|
|
|
|
Пока то-сё уже первый батерфляй отшипили. Есть ли смысл пилить на спартанах, когда там такие вкусные батерфляи?

Я предлагаю 2 машины по 6 х 6770, или одну машину с 4 х 6870
|
|
|
|
|
дык хоть бы получилось чего =\
|
|
|
|
|
брать 6х6770 (6х5770). Ну или 5. И матери соответствующие. Получится 2 машины.
Если 4 видюхи, то 6870
|
|
|
|
|
так дома поставь. Атомы тихие, вся железка жрать будет 200 ватт на 4 гигахеша. Сунул в кладовку в коробке из-под ботинок и пускай работает.

Why validity of more recent block are higher then late blocks?
Block 164217 (441) has validity 100/120
and
Block 164243 (443) has 112/120
BTW for block 164217 there are a chain up to 164354 (more then 120 blocks)
