Dell PowerEdge with GPU

[SteveiJobs]

Background:

 

I'm trying to do some proof-of-concept work with GPU passthrough and RDP acceleration for a work project (thin clients) and I got a loaner R730 from my IT department.

 

The issue I'm running into is that the BMC won't even let the server power on with a GPU installed because of an overcurrent. I looked in the BIOS and the total load without GPU is 434 watts (2x 750W 80 Plus Platinum power supplies). I get that at max, the system may get close to the limit, but the WX7100 I'm trying to install pulls a max of like 35W.

 

Anyone have any experience with Dell servers and GPUs? I get that the WX7100 isn't "officially" supported but that's a hurdle to jump through after I can at least get it powered on.

what riser are you using?

 

 

How are you getting power for the 6 pin the card?

 

I think you need a gpu kit for those servers to be able to use gpus, and those come with the correct risers and power cables.

I'm using riser 3. It has 2 x16 slots but maybe only one is coded for a GPU?

 

As for cables, I got one from SuperMicro that goes from the riser molex connector to the GPU. It physically fits but now that I think about it, maybe the pinout is wrong? Not sure if Dell uses industry standard conventions or if they do some weird proprietary stuff.

Id make sure to get the dell cable.

 

Did you try the other slot?

-The R730 can support two 300W, full-length, double-wide or four 150W, single width GPUs.

-The GPUs are installed on the PCIe x16 Gen3 interfaces available on Riser2 and the GPU-Optional Riser3.

-For installing two internal GPUs in the system, GPU-Optional Riser3 has to be present.

-The cables will be GPU specific as well.  example: https://www.amazon.ca/Dell-490-BCKS-R730-GPU-Installation/dp/B01A9GL9I6
