Re: Anyone have any idea how to control a Win 8 rig from another room? Wireless KVM?
There are some KVMs on the market which sends the signal over a standard ethernet connection.
You can place the KVM in the room where your rig is and then you need only a network connection to it. could be wireless of cause.
I think solutions like TeamView, RDP, VNC or similar products would not fit you because you loose to much speed. As far as I understood you like to work on the rig like sitting in front of it. So the wireless KVM is a choice or the other wirless alternatives already given in the thread.

BFGminer seems to be more informative as to what's going on. This is after a short time period but it keeps doing the same thing.
bfgminer --scrypt --thread-concurrency 10752 -g 2 -I 20 -w 256

I tested one of these cards on a different pc and I get the same issue. There must be something in my config or drivers. I just installed 13.4 ccc on the new pc I tested. They were running 11.11 previously.
"auto-gpu" : true,
"auto-fan" : true,
"gpu-engine" : "900-1040,900-1040",
"gpu-fan" : "65-85,65-85",
"gpu-memclock" : "1450,1450",
"gpu-vddc" : "1.060,1.060",
"temp-target" : "70,70",
"temp-cutoff" : "80,80",
"temp-overheat" : "75,75",
"algo" : "c",
"api-port" : "4028",
"expiry" : "120",
"gpu-threads" : "4",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"temp-hysteresis" : "3",
"donation" : "0.00",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
I'm not familiar with BFGMINER settings, but looks more or less the same than cgminer conf.
If I get it right with the config from above EACH GPU will use 4 threads. Shouldn't it be "gpu-threads" : "2,2" for each GPU to use 2 threads?
What does algo: c mean?
you can also try to use only one thread, in this case you can double the thread-concurrency.

I set up a new rig today, sapphire dual-x 7970's with cgminer on windows. I got it to 715k per card, but only around 10% of the work gets credited to the pool. The shares are not being submitted in cgminer either.The problem seems to be the intensity, I've tried a couple pools, and different settings. It's works fine at intensity 13 and starts going down with anything above that. This issue seems strange to me but I only switched to ltc recently. Anyone seen this before?
could you provide some stting you are working with? OS? Do you see HW Errors in the cgminer?

Here's my batfile :
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer -o stratum+tcp://stratum.wemineftc.com:4444 -u maursader.1 -p x --scrypt --gpu-engine 1075 --gpu-memclock 1485 --thread-concurrency 8192 -I 13 -g 2 -w 256 --lookup-gap 2 --no-submit-stale --auto-fan
742.2khash/sec , could push it to over 750 if i wanted to, but it's too hot here atm
Current temp : 74°
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer -o stratum+tcp://stratum.wemineftc.com:4444 -u maursader.1 -p x --scrypt --gpu-engine 1075 --gpu-memclock 1485 --thread-concurrency 8192 -I 13 -g 2 -w 256 --lookup-gap 2 --no-submit-stale --auto-fan

Thank you for the suggestion, here are the results:

Run this
Code:
cgminer --scrypt -o stratum+tcp://stratum.wemineftc.com:4444 -u maursader.1 -p x --intensity 13 --worksize 256 --thread-concurrency 8192 -g 2 --gpu-engine 1051 --gpu-memclock 1722 --auto-fan
This caused the computer to lock up, lol.
I wonder if it's got anything to do with the thread concurrencies, and I only say this because when I run cgminer by itself, it tends to choose 22400 for the value.
Any thoughts on that?
I would suggest to set all the values for each card separated. even if they are the same cards with the same gpu it might be due to some manufacturing tolerances that they react different on the settings. Than you can try to find out which settings suits each card.
I had such an issue in the past with 2 x HD5770. they where in need of different settings in terms of CPU and memclock

Hello fellow miners 
I have some troubles with 5870 cards running with cgminer 3.3.0 under linux (ubuntu 12.10, 3.5.0-28-generic kernel).
I setup drivers from AMD site for HD5*** series and tried different SDK version ( 2.5, 2,7, 2.8 ) but only got HW errors in cgminer, zero valid shares (tried various pools).
Interesting thing is i got it to work somehow yesterday and it was hashing bitcoins OK for several hours but after poweroff cycle for night, thing refuse to work again only generting HW errors...
Does someone know what combination of software required for this old cards?
For sure you have to take care that the SDK and the driver are compatible, there is somewhere an compatibility matrix on the AMD pages.I have some troubles with 5870 cards running with cgminer 3.3.0 under linux (ubuntu 12.10, 3.5.0-28-generic kernel).

I had the same issue with an 5850 running Ubuntu 12.04.
If you let cgminer choose the settings HW errors may occur, because of a too low thread-concurrency
1) make sure to issue
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
in the console
2) start cgminer with worksize 256 and thread-concurrency of at least 4096 ( I think you can start right away with 8192)

Re: Consolidated Litecoin Mining Guide for 5xxx, 6xxx, and 7xxx GPUs
In general the result in termes of hashes should be more or less equal. But for LTC it is kH/s instead of MH/s for BTC. Not sure but I think I read something about factor 0.9xx
according to the config you use the same settings for different cards, this might lead to the HW errors. Set the parameters for each card helps perhaps. Also for the finetuning. If your computer is dedicated to mining you can raise the Intensity to 16 or even more. Shaders setting is obsolete as long you are also using the thread-concurrency setting.
Also the thread-concurrency can lead to HW errors if it is set too low. Some said the tc should be a multiplier of the shaders, some say it should be a multiplier of 64. good is what gives best hashrate.
RGDS
thank you very much. yes all you said is correct. found that info online and tried to apply it to my bat file. im using my pc everyday and need my first gpu to handle all my work without any lagg. after i found out how to apply different settings to my gpus HW were much more easy to get rid off. to find a good thread concurrency without HW i did 6144 - 64 - 64 - 64 untill i found a good spot.
This is how my bat file looks now :
color 02
cgminer --scrypt -o http://stratum.give-me-ltc.com:3334 -u xxxx -p xxxx --thread-concurrency 4352,5600 --auto-fan --temp-target 83,75 --auto-gpu --gpu-engine 800-900 -I 12,17 -g 1 -w 64 --temp-cutoff 91
With this i get :
6870 : 82c 2700rpm 246 khash 0 R 0 HW 2.3 shares per minute -i 12
6850 : 74c 2780rpm 259 khash 0 R 0 HW 2.5 shares per minute -i 17
i know i can press both cards a bit more etc but since i need some of the computing power and GF hates the fan noise this is the setting im okey with.
Ah yes, the WAF .... (WomanAcceptanceFactor)
Good that it works out for you, glad to read that. But I'm a bit curious about the temp of the 6870. I think 2700rpm is something like 30-40%. I can imagine you did chose the temp target to get the best solution in terms of noise. But perhaps there is something inside your rack to optimize airflow. Seems abit to high for me with intensity of 12.

Re: Consolidated Litecoin Mining Guide for 5xxx, 6xxx, and 7xxx GPUs
Hello . hoping that someone with 6870 gpus or some knowhow can help me out.
I just started mining LTC but im getting less share per minute then with BTC mining. im getting few HW on one of the cards. alot of both if i change thread concurrency

cgminer --scrypt -o http://stratum.give-me-ltc.com:3334 -u xxxx -p xxxx --shaders 1120 --thread-concurrency 4800 --gpu-engine 900 --gpu-memclock 1000 -I 13 -g 1 -w 64 --temp-cutoff 95
xfire 6870 6850
win 7 64
latest drivers
latest sdk
works perfectly fine with btc
Im not sure what the thread concurrency should be at but 4800 gives me best results so far

Re: Consolidated Litecoin Mining Guide for 5xxx, 6xxx, and 7xxx GPUs
Anyone give me some advice about run LTC with MSI 7950 Twin Frozr 3GD5/OC (performance ,save power)
my config :
cgminer --scrypt -I 20 -g 1 -w 256 --thread-concurrency 21712 --shaders 1792 --gpu-engine 1050 --gpu-memclock 1250 --gpu-vddc 1.063
my hashrate about 610-625kh/s.Is this a good choice?
I use driver on MSI website :MSI Graphics Driver 9.002 amd_9002_v78_vga (Window 7 x64)
Thank for help

I think this is not too bad for the Card, at least not if I compare it with what others receive. But with some tweaking it should be a couple of kH/s more.
on a side note: in your config you can skip the shaders option, it is obsolete as long as you use the thread-concurrency option. And perhaps it is worht setting the auto-fan feature.

Block Eruptor können kein Stratum sondern nur getwork soweit ich weiß.
Also braucht für btcguild auch nen proxy
Also braucht für btcguild auch nen proxy
Gibts da was oder weißt wo ich Infos finden kann
Soweit ich weiß kannst Du dem mining proxy beim Aufruf über die Kommandozeile ein paar Parameter mitgeben.
Ohne paramter verbindet er sich automatisch zu bitcoin.cz.
in der Konsole mining_proxy.exe --help wird weiterhelfen
Hey,
soweit ich weiß setzt der GUIMINER automatisch folgende Befehle ab:
setx GPU_USE_SYNC_OBJECTS=1
setx GPU_MAX_ALLOC_PERCENT=100
Wenn Du Windows gestartet hast öffne eine Konsole und gebe die beiden Befehle ein. Und starte danach mal den cgminer.
interessant wäre auch die Konfiguration des cgminers. bei einer 5850 hatte ich das Problem das cgminer die thread-concurrency zu gering gewählt hatte, da hat es dann nur Hardware Errors gehagelt.
Ich hatte die thread concurrency dann händisch auf 8192 eingestellt. und dann hat es gebrummt.
Da ich inzwischen auf Linux zum mining umgestiegen bin bin ich mir über die konfig nicht mehr so ganz sicher aber so sollte es in etwa gewesen sein:
-tc 8192
-w 256
-g 1
--auto-fan

Re: Totally "off-topic," but what music are you listening to right now?
A german group called "Kraftwerk"
They exist since the late 60s. Some call it electronic pop, some don't. Anyways, they where quiet famous in the 80s in some clubs in NY, and they inspired a lot of other musicians.
Even nowadays. Coldplay for instance used a part of "computer love" in their song "talk".
