DELL R720 GPU

Question

Hello

I am looking to install 4x NVIDIA Tesla P4 on dell R720, but I am not sure if they going to work with it

https://www.techpowerup.com/gpu-specs/tesla-p4.c2879

this specs shows that Thermal design power is 75 W, but still not sure if it can handle them

there is no Supplementary power connectors on Tesla P4

Thank you

Yes Tesla P4 is working, but if you want to get max performance of it, you have to tweak the Fan speed of the server with IPMItool.

Because I am currently using btcrecover I am using 70% of the GPU capability with this software I set the minimum speed of the fans at 30% and the GPU steady temperature is 55.2C

Now I am going to push it to its maximum capacity and the maximum noise level of the server, that my neighbors can handle

So, yes it is working

Tesla P4 is not a supported GPU on R720. As it is not supported it is not validated and we can not guarantee that it will work.

R720 support Single wide GPU on slots 4,6,7 and 5. Please find below link for more details

Yes yes. I know what is supported by the book, but those are junk gpus. also by the book slots 3,5,6 and 7 supports up to 75W and this GPU is exactly 75W TDP.

Off the record is the slots can handle 75W or this is just an other fantasy number in your books ?

Thank you

Hi, may I know how can I set Fan speed when gpu running at a spspecific temperature in Ipmitool? I just got a tesla p40, but when the core runs up to 90℃ the fan still at low speed. I use Tesla K80 doesn't have this issue. By the way I'm using Proxmox as base system, and gpu passthrough to a Windows 11 VM

DELL-Chris H · Answer

IzumonoOkuni,

There are a couple things I can see right off the bat. The first is that I am not seeing the P40 listed as supported on the R720, and the other being that Proxmox isn't supported as well. With those being said, what I would start with doing is making sure the servers BIOS and iDrac are up-to-date and current Now if they are far behind then you will need to walk them up to current together to avoid causing other issues. After updating I would look at the idrac and see if the fan offset or any other fan setting is limiting the fan speed.

Let me know if this helps.

My R720 currently has:2x Tesla P4s (75W), and a USB3.1C riser card in the 3 half height positions. All are directly assigned to VMs. P4s are used for local compute for Plex and a couple docker stacks. I also have a MSI RTX 4070TI super 16G (blower) in one of the double wide slots, also passed through to a VM acting as my primary workstation, and used for gaming and GPU partitioning under Windows 10/11 to support a further 2x nested VMs for whole home virtualization.Power supplies are dell 1100W, processors are 2x xeon 2680v2 at 115W (out of spec for GPU use). 192 GB Ram, and fully populated drive bays (SSD and 10k Rpm banks)It is rock solid, noise levels are acceptable, as are temperatures. Dell does good work. Period. They say they don't support, and that is valid from a business use case. But I'm telling you, you have some leeway if this is a fun build, and not mission critical.
