DELL R740 Server GPU

Shine's assist is spot on. You could also send me your service tag by DM for further troubleshooting.

Can you share the part number of the cable which you have? You can refer below link for GPU requirements and installation steps for PowerEdge R740.

Hello,

I tried to install the A100 GPU(80GB) into the R740 it work perfectly, but when I install the same GPU into R7525 server, it give me power issue, and I'm not able to boot because of the error. I tried the A100GPU(40GB) into the R7525 server, and it work great. Please advice.

"The system halted because system power exceeds capacity."

Thank you.

Hello YAPYAP,

Did you get the GPU Power Cable Install Kit R7525 and R750?

On the R7525 the A100 80 GB has only been validated on riser configuration R1A + R2A + R3A + R4A (Full Length) .

Check you are using one of the Slot priority order: 2, 5, 7

Hello YAPYAP,

Ok, maybe we can tell by the service tag.

Per your statement:

 "I install the same GPU into R7525 server, it give me power issue"

Could you Private Message the R7525 Service tag to Young?

I am at shift end today.

Can you also tell us the kit part number you ordered for the power cables?

Hi,

Yes, I do have the GPU Power Cable.

I don't quite understand the riser configuration. I have attached a reference photo, I install the GPU in the middle (Riser 3) as you can see in the photo.

Hi Charles,

I don't know the part number of the power cables, it come with the Server. 

Hello,

did you share the service tag as asked, to know your riser configuration?

Hi, 

Yes, I just PM the service tag to Young

Hi, 

I have sent both of the service tag to Young.

Can you share the service tag of the R7525 too?

Hi, 

Currently I have 2 Server:

1) R7525 with A100 40GB, which is connected using the DPHJ8 you attached in the first picture (Run without a problem)

2) R740 with A100 80GB (Run without a problem)

However, when I try to switch the GPU, it gave me power issue

1) R7525 with A100 80GB, which is connected using the DPHJ8 (Power Issue)

2) R740 with A100 40GB (Run without any problem)

Thank you. 

Hello YAPYAP,

I will let her know you did.

Can you specify which GPU you are trying to get to work in which Server?

Did that unit come with the power cables for GPU?  I don't see them in any of the pictures.

Check the attached picture of power cables.
