@jabuzz , I took a hiatus for a while. I have since then just been using the 1 RTX 4000 Ada. I hope to find someone who can make a custom cable for me sometime as I have 0 confidence in those cables mentioned as well. The second RTX 4000 Ada has been sitting in its sealed packaging for a while. I hope to find some time to get this up and running again sometime soon. I really appreciate your response!

Dear Chris,

Appreciated for your help. :emotion-2: Should I ask you more detail on the GPU for the R730?

The question is: Do I need to choose only Manufactured by Dell (in the catalogue: accessories.ap.dell.com/.../category.aspx or other OEMs shall fit on my R730, based on its TDP?

Thanks forward for your answer.

Hi Chris,

You wrote "It also looks like the cables will be GPU specific as well. "

I have a R730 with a 1100w PSU and the GPU installation kit.

I just bought a Nvidia Tesla K80. Do I need any extra cable specific to that card?

Thanks a lot

Hello,

yes it needed a specific 8-pin cable designed for the NVIDIA Tesla K80 cards as a standard GPU power connector is not compatible.

Thanks

Marco

As far as I can make out the standard GPU power cable (part no 09H6FV) won't power a K80 as the connectors are wrong. At least the ones I have won't. If you are handy with a soldering iron (or have the correct crimp tool kit) you can just get a Molex Mini Fit Jr 4x2 plug snip the ends of the Dell part (it can power two single cards but the K80 is double height) and fit the power plug. I don't have the crimp kit (it's expensive) so I do it with some needle pliers and then because that's not great, to make sure the electrical connection is good use a small amount of solder. Too much and the pin won't fit in the housing properly.

You will also need a special Dell specific metal bracket to support the end of K80 card, these are not cheap to get hold of as you are generally going to have to buy an older card to get them. Here is a picture of a P100 with one of them attached sitting on top of a PowerEdge R730.

Any unused PCI slots need covering up with solid covers as opposed to the ventilated ones that are standard. Presumably to force additional air flow over the card.

You are also limited to processors with a TDP of 135W or less and maximum inlet air temperature is reduced to 30°C.

Where the R730 owners manual talks about "low profile" heat sinks being part of the GPU enablement kit, it is as far as I can make out talking rubbish. I think it's a hangover from the R720 owners manual that should have been removed. At least I have not come across an R730 that needs different heat sinks. On the R720 you also need to replace the ducting shroud which means changing to low profile heat sinks (more powerful fans too). However from what I have seen empirically the R730 comes with "low profile" heat sinks that sit under the standard ducting shroud.

A P100 works in an R730 with the above, and  a V100 does too as it uses the same amount PCI base address register space. Presumably the V100S does but I can't attest to that. Later this week I will be able to let you know if the latest A100's work as I will be getting a loan of a sample. They use more PCI base address register space, significantly more if you make use of the virtual GPU feature and the R730 BIOS might not reserve enough space (hence the load of an A100 before we make a significant purchase).

Finding this all out has been a significant amount of research over the last couple of weeks, which is why I have a R730 on my lounge floor to work out exactly what the GPU enablement kit included. I already new the power lead was duff from a while back. Just need some extra R730's to expand our offering. We want a heterogeneous cluster and limited money for new servers anyway. Will just have to live with the A100's on a PCIe 3.0 bus assuming it works.

Hi Sir,

I have purchased RTX3070 Cards will it support DELL PowerEdge R730 / xd Server. Please help with this.

Hi,

Unfortunately Client graphic cards does not go with servers.

Hello,

thanks for the update.

Yes we don't have this kind of documentation, unfortunately.
