I have the same problem. The solution that works for everyone is to install the propietery drivers from ATI - however their site is down! Anyone knows where to get the .run files except from the official ATI pages, which are down since a couple of hours?

Edit: Found the driver on another mining rig - so if you guys need the file as well, send me a PM.

Try if you can get your hands on a beQuiet PWM/USC SilentWings Fan. They are engineered in Germany and are the best I ever had. I mean these badboys are completely coated in rubber! oO


Q: Would you position a fan to blow between the GPUs from the Top or from behind in direction of the caseslots?

Cool this is Linux Catalyst 11.6 as well - http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx

I wonder if its in the repos already, e.g. akmod and kmod.

I'm happy I cancelled the 6950. Shaders are everything.
1485  Other / CPU/GPU Bitcoin mining hardware / Re: Undervolt Minercard? on: June 17, 2011, 10:11:34 PM
Undervolting: Thanks for the answers, I found it intersting to read about power cycles and how they wear down the longevity of hardware. As for undervolting, I am positive it wouldn't effect performance of a chip, it just alters the voltage which is needed for the electrons to jump over into another state, or am I wrong?

Cooling: 4x Arctic Twin Turbo Pro and 4x Arctic VR001 and 4x BeQuiet PWM 120mm and Open Window.
Alternative cooling suggestions are welcome! Water cooling is a bit too expensive for 4 cards for my taste.


Longevity and Thoughts: Greed kills. Keep it from a long time, Stock, Future, Forex, Metals, Options Trader. That's why I will do this "just for fun", like the inventor of Linux once stated. I won't push my GPUs to the max. I will sell them later and I want the new owner to be happy not to be angry at me. I pushed my 5850 to 360 Mhash/s without voltage tweeks and its in the burying ground now.

Invest in yourself
The four 5850/70 I bought will make me happy a long time, since I will treat them well. 300 Mhash/s max with lowest memory clocks and extreme cooling. 1-2 hours off time a day. I even gave them names. Wink Mining is just a game and people don't see that easy money NEVER stays with its owner very long. If you want to make money, invest in yourself, go to University, buy a book, heck buy clothes.

Anyone here undervolts their GPU's for prolonged longevity?

I would be interested in their experiences. I plan to overclock by not more than 10% with massive, massive cooling installed on my cards. The memory down to 300 MHz and the Voltage I am not sure about.

Controversies

Allegations of employee mistreatment

Allegations of employee mistreatment have been made on a number of occasions. News reports highlight the long working hours, discrimination of mainland Chinese workers by their Taiwanese co-workers,  and lack of working relationships at the company.

In 2006 the Daily Mail accused it of abusive employment practices. Although Foxconn was found to be compliant in the majority of areas when Apple audited the maker of its iPods and iPhones,  the audit did substantiate a few of the allegations.
[edit] Suicides
Main article: Foxconn suicides

Sun Danyong, a 25-year-old male, committed suicide in July 2009 after reporting the loss of an iPhone 4 prototype in his possession.

In reaction to a spate of worker suicides where fourteen died in 2010, a report by 20 Chinese universities described Foxconn factories as labour camps and detailed widespread worker abuse and illegal overtime. In response to the suicides, Foxconn installed suicide-prevention netting at some facilities, and it promised to offer substantially higher wages at its Shenzhen production bases.
[edit] Imprisoned Indian workers

In October 2010 over 300 employees of an Indian operation in the Special Economic Zone of Chennai were arrested and jailed by Indian authorities for taking part in a strike.

All but a dozen of the arrested were soon granted bail.[28]
[edit] LCD price fixing

In December 2010 Chimei Innolux, a maker of LCD screens in which Foxconn has 24% ownership,[29] was fined by the EU for price fixing.[30]
[edit] 2011 explosion
Main article: 2011 Chengdu Foxconn explosion incident

On 20 May 2011 an explosion and fire broke out at one of the factory in Chengdu. The incident affected the IPad 2 assembly line and caused deaths and injuries to numerous workers.
[edit] Sacred burial ground

About 200 to 300 years ago, an area where the current Shenzhen factory resides was the home of an estimated 4,000 Hakka families.[31] The land at the time was undeveloped. Peiziyuan (皮仔园) and Ghosthead lake (鬼头潭) is situated in the area.[31] Peiziyuan in particular was a burial ground of more than 1,000 babies.[31] This area continued to be a burial site well into the 1970s after the one-child policy was promoted.[31] Massive numbers of girls were killed in favor of boys, and baby corpses were collected at the site.

brought to you by http://wikiterms.net - I mine myself, but I keep an eye on where the hardware I buy is coming from. We the consumer, have the power to change the world IMHO.#

1488  Bitcoin / Mining / Re: 5850, low temp but still seeing artifacts? on: June 15, 2011, 08:30:46 PM
Don't listen to nazgulnarsil, xonar. They are probably undercover evangelists, read: Astroturfers for ATI, the company probably responsibly for this whole BitCoin thing.. lol. Just kidding, but wanting to make you think about the enourmous waste of resources of this project and who is the real benefitor; at the moment at least it is the hardware companies, foremost Foxconn ( https://secure.wikimedia.org/wikipedia/en/wiki/Foxconn#Controversies ).

I have the Sapphire Xtreme 5850 since 3 days now with Artefacts all over my Desktop, both in Linux Fedora Core 15, with or without Compiz and in Windows. I plugged the powercable of my high-end Enermax PSU and gave it a 15 minute rest, still seeing artefacts, a lot of them. I mean it's really really ugly, I can't see anymore.

This is all it took to destroy my poor Sapphire (RIP)  Cry

Clock to 890 (core),1000 (mem)
Agression=11
Fan=60
Temps: 60°C

Let it run 24h on that settings.

The card is now longing for the trashbin. The damaged VRAMs probably will cause damage to my not-so-cheap-either 1155 board, too.

Underclocked the card now to 300 (mem) and overclocked exactly 10% to 797MhZ (core). This gives me 15% less hash rate return, however a 100% return on my $199 investment in the 5850.
1489  Other / CPU/GPU Bitcoin mining hardware / Re: Will a Motherboard withstand 5 Graphics Cards? on: June 14, 2011, 01:47:28 AM
75W * 5 =375W thru PCI
75W * 4 = 300W thru PCI

So why are people able to run 75*4 configs w/o problems?

I would be very interested on how to splice 12V directly into the Risers. Do you have a link..? Smiley
1490  Other / CPU/GPU Bitcoin mining hardware / Will a Motherboard withstand 5 Graphics Cards? on: June 14, 2011, 01:24:29 AM
If I would use PCIe 1x Riser Cards with a Motherboard (e.g. 1155 ASUS Z68 or ASRock Extreme 3) and use all PCIe that MoBo is giving me - will the MoBo fuse or burn my house down? The setup will be properly cooled of course. Which MoBo manufacturor is the most solid for these kind of task?
1491  Other / CPU/GPU Bitcoin mining hardware / Re: Which Z68 or P68 board for tri or quad GPU setup? on: June 13, 2011, 05:27:21 PM
Hi again - I can't help you with your Guiminer/6870 problem, I highly recommend to open an own thread with a meaningful subject for this and answers will start coming.

As for the Linux/Windows discussion, I agree with you, in terms of Usability I would chose OSX first, then Windows 2nd and Linux last. However, I invested time and effort in Linux since 2002 and even own some certifications. Therefore I was able to set up the whole mining game in 1-2h on Fedora15. It doesn't make sense for me to go back to propietery software for me now. I -LOVE- the fact that GNU is a political movement and Linux is the biggest community effort I have ever witnessed. Making money isn't the top priority and that's why Linux matures over time and doesn't get worse 8except maybe Gnome3, lol). The endless number of tools that come preinstalled with FC15's KDE made my jaw drop.

There are 200 distributions - and you should try a quite a few. Enterprises tend to use RedHat or Debian and at the moment of writing ArchLinux, Fedora (RedHat) and Ubuntu (Debian) are the most favored amongst end-users. This can change anytime as Gentoo or SuSE were really the Linux OS to use in the last decade. For mining, Ubuntu is the most well supported - so I recommend that one, there are also some pre-compiled VRAM / Voltage tools around in this forum that you can install in Ubuntu w/o compiling.

If you settle down on Fedora or Ubuntu it is mandatory that you buy yourself a book about package management with RPM, DEB, YUM and APTITUDE. Without having profound knowledge of package managment of your chosen distribution you will be absolutely lost.

If you really want to start with Linux now for the purpose of mining, prepare for a rough ride. You will learn a lot and probably start hating Linux - but it will pay off later when you get a $90K+ offer by Akamai w/o ever having attended University. =oP

Now... back to topic - I found out that all P67 and Z68 boards by ASUS have massive bugs, like sleep modus won't work and the multiple boot bugs. This seems still to be the issue with latest Rev. 3 boards, also for Z68 - so beware of ASUS! After having read a lot I would recommend these manufacturers for the 1155 socket, on the top of the list being the best (I did no research on Gigabyte, since I do not like their lack of UEFI Bios):

(1) MSI (Stable / €160)
(2) ASRock (Very bad cooling on MoBo-Bridges, shld upgrade w. Zalman / €140)
(3) ASUS (A lot of bugs! / €130)

Any more thoughts on the topic of "1155 mining"?

You hijacked this thread, now you have to live with the consequences.  Grin Did you try dummy plugs for your cards in Windows? I highly recommend to switch to Linux, gives higher hash rates and Compiz-Fusion looks better than any OS on the planet right now.
1493  Other / CPU/GPU Bitcoin mining hardware / Re: Which Z68 or P68 board for tri or quad GPU setup? on: June 12, 2011, 08:25:08 PM
Don't use Windows for creating a cryptographic, decentralised and open sourced currency. Windows is the opposit of all three things.
1494  Other / CPU/GPU Bitcoin mining hardware / Re: Which Z68 or P68 board for tri or quad GPU setup? on: June 12, 2011, 08:01:06 PM
Nice prices for a riser! Will the Z68 even be able to handle four or even six 5850 cards? The MSI obviously does.
1495  Bitcoin / Mining / Re: Recommendation for unlockable 6950? on: June 11, 2011, 04:53:37 AM
I found a Powercolor 1GB 6950 with DualBios Switch. Would it be possible to unluck the shaders then with a modded BIOS?

This topic may clarify my Question with the 1GB version ( http://www.overclock.net/amd-ati/996523-just-unlocked-powercolor-hd-6950-1gb.html ). The 2GB version as you wrote is doing fine.

I can get the 1GB version for $30 less and 5 days earlier.

Edit: I decided to go with another GPU. The 6950 is indeed a bit overkill for mining.
1496  Bitcoin / Mining / Re: Recommendation for unlockable 6950? on: June 11, 2011, 02:38:51 AM
I can answer this myself: Some are unlockable, some are not. It is all luck.
1497  Other / CPU/GPU Bitcoin mining hardware / Re: Which Z68 or P68 board for tri or quad GPU setup? on: June 11, 2011, 02:11:09 AM
I see - however I got the 2500K for $100. Grin I also want to have a nice Workstation PC when the Goldrush is over. Do you have a link to such an extender? Cheers.
1498  Other / CPU/GPU Bitcoin mining hardware / Which Z68 or P68 board for tri or quad GPU setup? on: June 11, 2011, 01:16:35 AM
Which board would some of you pro-miners recommend if I have an idle Sandybridge CPU lying around and want to get 3-4 6870 or 6950 cards?

This ASUS board should support quad setup, but I have no idea how 4 cards should fit into the board. I see no difference to the Asus Z68 Pro.

1499  Bitcoin / Mining / Recommendation for unlockable 6950? on: June 11, 2011, 01:12:20 AM
I am not so sure if there are differences between GPU card vendors, e.g. is a Powercolor worse than an XFX?

http://geizhals.at/deutschland/a619993.html
http://geizhals.at/deutschland/a636250.html

It goes unsaid that I want to unlock the shaders and get the most out of it for OpenCL.  Grin
