  1. @SpaceGhostC2C Thanks a lot for your help and detailed descriptions. I tried a lot of different configurations, BIOS versions NVIDIA drivers, ... Sadly my mainboard does not support some of the described Features like ECC, even though played with a lot of relevant modifications. Any how, I just bought a new Mainboard and can probably describe my results by next week. Since this might be interesting for others too. If it doesn't work, i will probably buy some old server of ebay that officially supports the K80 and start from there
  2. I feel pretty confident about it, since it shows up in the PCIE device tree but is not able to be recogniezed as a gpu. Furthermore, i tested different GPU configuration. Quadro + Tesla, GTX + Tesla, ... and de PSU supplies enough power corresponding rail. But my confidence might be the result of a lack of other clues. I thought that i played around with enableing and disableing it during my last test run, but i will do it again. Yes, its a dual GPU card and this was one of the reasons why i like the k80 so much. I used it a lot in rented server hardware and wanted to play around with one in my workshop The connected PSU and the GPU connected rail can supply engouht power to the GPU. Furthermore I will lend me a bigger PSU from a friend next week, so i can completely cross this from my list of possible reasons. Thank you, this is my priority, too
  3. Is there a bios setting that is called enable/disable "above 4G decoding" or something similar in the bios? Do you know their RAM capacity? Mine is 8GB for the video output card and 24GB for the Tesla K80. Is you video output card bellow 4GB? If not i am very confident, that this might work for me, too. It would be cool to use them in tandem, but honestly i am quite confident, that Tensorflow can handle it. The main issue is, that my current main board is not recognizing the K80 correctly, since it can not adress it without the 64bit pcie adresses (aka. "above 4G decoding"). Thanks a lot for you support @SpaceGhostC2C
  4. I don't have the settings for it and BIOS updates/downgrades did not help. So you mainboards bios supports BAR 64bit and lets you enable it in the bios? If so this would help me a lot, since could just buy you mainboard and hope that everythings will work out. Of couse, this is no guarantee that it will work for me? What kind of GPU Setup did you use? @SpaceGhostC2C Did you use two GPUs, ...?
  5. Hey everyone, I am currently running an AMD FX8350 on a ASRock 990FX extrem 3 Mainboard and now facing a few issues while getting my K80 to work as a secondary GPU for handling ML workloads. Sadly i can not get BAR 64 (above 4G encoding) enabled on my mainboard, therefore i am currently looking for a cheap replacement. Are there any other search phrases besides "above 4G decoding" or "BAR 64bit" that i can search for in the mainboards datasheets? Or does anyone know how a AM3+ based Mainboard with two PCIE 16x slots, K80 support and BAR 64 option? My current setup is really bodgy 2 PSUs, one for each GPU, and a custom 3D printed fan setup for the K80. Was really fun to set it up, even though it feels kind of dirty Best regards Langhalsdino
