Were you able to connect your Tesla K80 to your C8000 system directly as you wanted? In addition, in the K80 cards, Nvidia announced the presence of an NVlink between the two GPU chips, which should have allowed using 2 banks of 12 GB memory as one 24 GB bank to work with large data blocks...

Empirically, I installed a video card in the store by sticking it into the card that it works with GTX 710, 730, 1030, GTX 1060, 1070. But with GTX 1650, RTX 2060 and 3060 - no. Keep this in mind when assembling your workstation.

By experience I found that GT 710, 730, 1030, 1080, HD 6450 work on my 6220 board. But GTX 1650 and 3060 do not.

Faced a problem, my Dell C6220 II board cannot turn on RTX 3060 12gb, older cards are working. Who faced and solved this problem?

I'm glad I could help you. I hope you won't have any problems. About the risks of using two power supplies, I meant that when powered from two sources, there can be two situations dangerous for your equipment. 1. Inside the Tesla K80, in the system for forming the phases of the processor's and...

I realized that you want to disconnect the narrow boards with 16x slots and p797 built into them. But you must understand the risk that the voltage from the box can get into your C6220 / K80 and disable it. Personally, on my assembly with a pair of K80, trying to power the cards from 2 different...

Boxes S1070 and S2050 have their own electronics that controls 16x slots, determines which cards are in them, compresses and generates signals for transmission via special cables to P797 HIC cards. If you take a riser cable like mine, cut it off and solder it directly to the 16x slot inside the...

If you have an employee who knows Russian, I can give my Skype for communication.

Trying to connect cards directly to boxes C2050-C1070 directly from the 6220, you will most likely simply damage the equipment. Even if it does not burn out for you - due to the fact that the cables will not be made of high quality and the electronics of the card boxes working on their own will...

On GPU risers from Dell servers such as yours, on boards with a 16x slot nearby, there is a 4-pin + 12V power connector that feeds it directly to the card. 4-pin connector on the GPU riser board - supplies + 12V power directly to this 16x slot. In order not to load the power lines of the board...

The Edge slot option is visible after connecting an additional +12 V power supply and a card to the GPGPU riser. Without an installed card, the slot is not detected. And the system only sees 2 GPU cards 16x. The third - no, but she sees the 4x SSD card. On 3 16x cards, the system lacks signal lines.

The orange button flashes when there is a power problem. Understated or overestimated voltage. If the blue LED near the USB connector starts to pass by, it means that somewhere in the power supply plus and minus are mixed up, my additional power was mixed up on the board, but she survived it...

I bought tools and made a power supply cable for + 12V risers for the GPU and for the board. Now it is qualitative. 2 х Xeon E5-2650L V2 10 Core + RAM 128 Gb + MVMe SSD Samsung 960 EVO 250 Gb ( /swap ) + 2 x SATA SSD Samsung 960 EVO 500 Gb ( / ) + 4 x Seagate 1 Tb ( /home ) + 2 x Tesla K80 +...

C8220X (0083N0) & GPU Tesla K80 ///////.......

The riser on the link above is not for the side mezzanine slot, simply psi-e, but for the slot on the narrow side of the board next to the power connector. I myself wanted to use the 8x mezzanine slot for raid and an external network card by connecting my device, but I could not find the pin...

If anyone is interested in this topic - write, I will tell you in detail and take a photo of the equipment.

Good day everyone. If anyone is interested in assembling an inexpensive system for 8 GPUs from old components for professional computing, I'm ready to tell you what and how it was done. When assembling the system, there are features that are difficult to solve without experience, I'm talking...

I use original risers with additional power supply with two 083N0 Dell C6220 II & 8220x boards. There were never any problems. I use GPU Tesla, GPU GTX 1070 and tire SSD Samsung 860 EVO for swap file. The original risers have all the protection you need. Cheap Chinese risers do not have them.

And I thought about a cluster of 4-6-8 motherboards DCS 6220 II 0083N0 + ASUS Z9PE-D16/2L 6 PCI-E 16x + 4-6-8 intel X540-T2 2x10 GBe LAN.

He could make boxing coolers and slots PCI-E 16x 2.0 work. It turned out in order to make the coolers work enough to pull out of the slot or cut and isolate the two blue wires that go to the front panel board to which the coolers are connected that are blowing the video cards. In order for the...
