wie wäre es denn wenn wir kollektiv kubanische Zigarren bei ihm kaufen würden - mit BTCs... Das wäre doch richtig geile Presse Ich weiß ja nicht was die kosten, aber vorsorglich als Weihnachtsgeschenk oder so... Ich denke ich würds tun:-p

Hallo, ich finde es ebenfalls sehr schade, dass das Treffen abgesagt wurde. 22 + x Teilnehmer ist wirklich nicht viel, um großartig etwas zu organisieren. Aber immerhin - 22 Leute sind doch schon recht ordentlich für so ein jugens Nerd-Thema;)!!
Bevor wir das ganz beiben lassen, wäre nicht wenigstens ein kurzer Austausch in einer Kneipe lustig? Es gab ja schon mal ein Treffen. Die Leute, die sich als Teilnehmer registriert hatten, wäre sicherlich dabei! Sofern sie nicht von weiter her kommen... Aber Locals kommen doch sicherlich vorbei - wenigstens kurz;)
Ich selber hatte mich nur vorgemerkt. Ich bin etwas in Verzug mit meiner Diplomarbeit. Außerdem müsste ich am Samstag um 21:30 Uhr den Zug nehmen, länger als 21:15 Uhr könnte ich also nicht, wenn es abends stattfindet.
Aber ich wäre doch sehr an einem kurzen Schnack interessiert, um wenigstens die Gesichter von gleichgesinnten zu sehnen;)
Also dann, vielleicht klappt ja doch noch etwas;)

Actually I have just returned a GPU. It started crashing more frequently and finally I couldn't boot anymore. But I have no futher experience with this...
You are right with the ati drivers depending on X. When X crashes, for example due to the lock up of that specific GPU, than the ohters lock up, too.

I am running two 5850 with PCIe 1x and they work fine (oc to 970/300). I use extensios without molex. Anyway good point with the PCIe 1x power supply. Just make sure to use dual layered cables (I mean on each pin 2 cables parallel).

Hi, unfortunaltely I can't confirm that the mainboard supports 6 GPUs. One of my GPUs slowly died and now I have to send it back and order a new one. But I can say the slot in question works!!! I am still running 5 GPUs and this time I left another slot free. So I think 6 GPUs should work. But to be sure I might be able to confirm that in a frew days.

Hey guys, thanks for your ideas. Gigabyte support asked me to flash a beta bios on the mainboard. It could be an addressing problem, as only the one slot fails.
I am going to flash the mainboard on monday and try again - gonna keep you up to date;)
@jrobe121 A 1200W PSU does offer 1200W. A efficience of 89 % means it pulls like 1348lW out of the plug to deliver that 1200W. But no name PSU often have problems to deliver constant voltages on the 12V lanes...
Anyway - call you monday:)!!
Cheers, Harm

Hi, thanks for your answers. It seems to be just the one pcie 1x slot that doesn't like mining. Even with clocks 500/300 on all cards. Using only this one card at a time I can get it to 700/300 but no more...:-/
I think it is something with the slot...
Does anyone know a working mainboard with 6 pcie? Actually I haven't found an example in this forum, just people intendig to try that.

Bitcoin / Bitcoin Technical Support / GPU load 92%, python load 10%
|
on: July 20, 2011, 03:46:27 PM

Hey, I have got another question...
Sometimes I have a GPU load of like 92%. I am linux user and I discovered that the mining process (#ps u) "python ./phoenix.py ..." uses about 10% cpu load when this happens. I can kill the process and restart mining on that gpu. It is not a lock-up. But again, the load of one GPU ist around 92% while the other GPUs are at 99% and python uses 10% CPU load.
Does anyone have experience with this? I can't fugure out why the python process uses so much CPU time...

Bitcoin / Bitcoin Technical Support / 6 GPUs 5850 on one mainboard
|

Hi, I have put together a mining rig with 6 GPUs (4x XFX HD 5850 and 2x Sapphire HD 5850). With 5 cards everyting works perfectly, but the 6th one now causes trouble... It is not the card itself, it is not defect, but maybe the mainboard? Gigabyte GA-990FXA-D3 http://www.gigabyte.de/products/product-page.aspx?pid=3900#ovCorsair AX 1200w ATX PSU I have allready had defect pcie extensions, but the new ones work very good. My mainboard has four pcie 16x and one two 1x ports. Conntecting the 6th GPU to the 2nd 1x port my system boots without any problems. But right after starting to mine the 6th GPU lockes up. Well, some times it actually mines 2 accepted shares, but then nothing anymore... I have switched the two 1x adapters, both seem to be ok. I have switched GPUs, seem to be ok, too. My PSU does 1200W what should be more than enough: 6*170W = 1020W + 30W (CPU) = 1050W makes 150W for fans, mainbaord and backup. Downclocking my GPUs to 500/300 before mining, to reduce power consumtion, doesn't work neither. Any ideas? Why does the one pcie 1x port work, but not the other one?
