      That is most likely the power connector. You need make sure you use a CPU 8 pin connector and NOT a PCIe connector. Its not a normal GPU. Most likely it will kill your PSU or the cables. The card usually survives being plugged into a PCIe connector instead of a CPU connector as it shorts 12v rail to GND, so the PSU will go into protection and not start. If your PSU has short circuit protection it will work once you get the right cable.

    There is no need to use precise resistor values, you will not see any difference in colors by using the next closest resistor values. You can also use only 2 resistors for each RGB color and still have a very good color range. You are also using cheap metal film 10% tolerance resistors so the values can be out by 10% anyway.

  • @rohlay00
    @rohlay00 4 місяці тому

    I'm looking to build a dektop specifically to use this GPU, and the question of how many PCIes it should have has arisen. I was thinking maybe buying 2-4 GPUs. Your DIY solution increases the width of the GPU, does that mean, regardless of the number of PCIe x16 ports, a desktop PC can only have 1 nvidia tesla k80 gpu? Unless the cooling is done on the side instead of on top, thereby not increasing the width, and allowing more space between GPUs. But these GPUs are already pretty thick, so even if I did this, do you think you could stack 2-4 of these GPUs side by side on a motherboard that has the PCIe ports? Thanks for sharing your solution.

    K80 have 2 eCPU on them so need 2 fans or 3 on them ... Also on you video that demo it's used CPU and not GPU ... not normal to get 70-80% cpu usage .

    • @robingrosset6941
      @robingrosset6941 7 місяців тому

      Thanks for the comment. In a server, which is where this card normally belongs the card has no fans its cooled by airflow through the server chassis. The main thing is to ensure the card and each GPU is cooled, with this delta fan it is really overkill, these fans at full speed will lift off a desk by themselves. Its a bit too much cooling. I have tried 2 fans together and the issue comes back to where will the hot air exit the card. By design of the cooling fins the hot air flows over one GPU and then over the other there is usually a temperature increase over the 2nd GPU. You see in the video one GPU is 48 degrees C the other 54 degrees C. This is normal for these cards in server environments. There are some examples of overheating cards and normal cards at the NVIDIA forum link google "tesla-k80-overheating 38690" The temperatures in this video are well below the thermal throttling levels. If you look at NVIDIA SMI screen shot in the video you'll see the GPUs are loaded up 50% and 30% But notice GPU RAM usage is 100% on both GPUs.. so they are working hard and at the RAM limit. RAM limits are often the big factor in why folks use these GPUs 10:52 nvidia-smi 100% RAM used. Its normal for CPUs to work hard pushing data to the GPUs, but it does depend on the workload. This test is CPU and GPU intensive because I am running 8 parallel machine learning workloads and an element of this workload is CPU bound because its displaying the OpenAI Gym Space Invaders user interface at high speed. In terms of longevity for this setup I just took a K80 out of a machine after 3 years and its still running fine.

    • @robingrosset6941
      @robingrosset6941 7 місяців тому

      Yes you can. So inside the interrupt handler there is a call to a function pwm_set_gpio_level (uint gpio, uint16_t level). the second paramter is the level and this is from the WAV_DATA so you can setup the WAV_DATA to be 16 bit integers uint_16_t instead of 8 bit . It should work fine. Do you have a 16 bit sample you want to play as 16 bit or is it that you want to covert the 16 bit sample to 8 bit? The reason for this being 8 bit to begin with was to reduce the memory size needed to store the WAV data and make it more compact. But you can use 16 bit its just your sample memory with twice as big.

Okay now on to the real point would it be possible to 3D print a new fan housing for the m40 and k80 etc where you take all of those things off of the casing and expose the chips and whatever you were talking about and reverse the fans so that they are sucking air out of the GPU and blowing it straight up so it would be kind of heating my bedroom not just blowing hot ass air around inside the tower.??
