Ahmed,

The GPU enablement kit is required for internal GPU installations. It contains the power cables and other items to enable GPU support in the R720 chassis.

GPU enablement kit includes:

low-profile heat sinks

low-profile Memory shroud

Power Cables for GPUs

Plugs from card to PCI-e riser 2/3

One cable supports two card connectors

Provides support for cards that require more than 75W power

Different closeout EMI shields for unoccupied PCI-e slots

You will need to ask for it, either internal or external, if you want to use the feature.

With the ATI FireGL card, the R720 doesn't support using 3rd party video cards. As it conflicts with the embedded video.

Now that doesn't mean it won't work, but it is untested so there is no way to know if the card could work.

Let me know if you have any other questions or concerns.

Thanks Chris for your fast response,

got your point regarding to R720 doesn't support using 3rd party video cards, but still i can test it on my own responsibility

so do i need GPU installation kit for this? if I need what is the Dell part number

also in normal situation with certified Ati firepro V7800P do i need two cpu Intel® Xeon® E5-2620 or it can run with one only?  

Thnaks

Hi Ahmed,

I have just done something similar, and have the GPU enablement kit Chris mentions. Since I am only using one GPU and not using the low profile heatsinks, I can sell you the remaining half of my GPU kit if you are interested, which will come with the heatsink and power cable you need. PM me if you are interested.

Otherwise, the Dell part numbers that you need are a follows;

490-13616 GPU Installation Kit

330-10282 Additional PCIe Riser with x16 Slot for PowerEdge R720/R720xd - Kit

Note that you only need the additional riser card if you are;

a) installing two GPUs in a R720 server

b) installing 1 GPU in an R720 server but you want it connected to CPU 1 (instead of CPU 2) and therefore need to install it in the left hand riser bay

Note: if you are installing in an R720 server for CPU 2 only and put it in the middle riser bay then you don't need the additional PCI card. Also, if you are putting it in a R720xd server, then the card will only fit in the middle riser bay so it can only connect to CPU 2.

The above assumes double-width GPU card; for single width it may fit into the left hand riser bay on a R720xd server too.

Also note that in my setup (Tesla M2070Q in Dell R720xd server) I have just plugged it all in and am seeing some PCIe card failures messages....I haven't had a chance to tweak it yet so it may just be my settings, but be warned this is not a supported config by Dell...

Hi,

I have a Tesla T4 and dell R720 server. I have one CPU, 16GB RAM. I face the restarting problem once i put the GPU in the server. Without the GPU the server works fine.  When I put the GPU, the server keeps on restarting. I put the GPU on x8 riser slot on the server. It has 3 slots. I tried all x8 slots. Same result. 

Hi Salman1,

I found taht the Tesla T4 is supported in our latest PowerEdge server systems, but not in the 12th generation (R720). This might be the issue here.

The R720 supports the following Tesla cards:

• 1NTYF Graphics Card, Nvidia Tesla K20 Passive, 5 GB
• 2YP0C Graphics Card, Nvidia Tesla K20 Passive, PCIe, 8 GB
• C5TR1 Graphics Card, NVIDIA Tesla M2075, PCIe, 6 GB
• D0P86 Graphics Card, NVIDIA Tesla M2090, 6 GB
• GJD61 Graphics Card, Nvidia Tesla K20X Passive, 6 GB
• KTDCH Graphics Card, Nvidia Tesla K40M Passive, PCIe, 12 GB, Dual Ports, Full Height, (255W)

Overall, I can give you some more information about using a GPGPU in R720.

The R720 will support up to four full-length single-wide GPGPU or two full-length double-wide GPGPU. Each GPU can support up to 6GB of dedicated GDDR5 memory and is either actively cooled or passively cooled. The GPUs are installed on the PCIe x16 Gen2 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 GPU enablement kit is required for internal GPU installation. It contains the power cables and other items to enable GPU support in the R720 chassis.

GPU enablement kit includes:

- low-profile heat sinks
- low-profile Memory shroud
- Power Cables for GPUs
- Plugs from card to PCI-e riser 2/3
- One cable supports two card connectors
- Provides support for cards that require more than 75W power
- Different closeout EMI shields for unoccupied PCI-e slots

GPU Card Restrictions
- Requires 2 CPUs
- CPU must be 95W or less
- Max of two double wide GPGPU (rule that they take up 2 slots)
- Max of four single wide GPGPU
- All GPUs must be same type / model
- GPU requires redundant 1100W PSU and GPU enablement kit
- Two double-wide GPU requires optional riser 3
- Four single wide GPU cannot have optional riser 3
- TBU not supported

Here you find the PowerEdge R720 and R720xd Technical Guide, it contains such information too. You can use it as a reference.

Hope that helps, let me know if you need more information.

Best regards,
Stefan

@rjtmerrett​ is it possible to get the part numbers of the power cable? That part is not listed anywhere
