Decinos,

Here is a link to the GPU Compatibility list. It will show the uses and the card models.

Let me know if this helps.

Chris,

Sorry but this doesn't help.

Because the page not include K10 and K20 graphic cards. Are theese cards tested?

Chris' reply should help, as it tells you which cards are supported/compatible.  The K10/K20 are not on the list, so they are not supported or officially compatible.  They may work, but it is up to you to try and to troubleshoot any issues, as Dell would likely not have tested them at all.

I have successfully run the K10s in Linux on the R720s. There is a PCI error message that you can skip and you need to modify the BIOS so that the fan speeds run at max. We get good performance out of them on our seismic processing.

Unfortunately, it doesn't work in Windows Server 2008 R2 SP1.

Haven't tried the K20s in Linux yet, will do so soon. I suspect Linux will work.

Trying to install the Windows Server 2008 R2 SP1 on the K20 results in a BSOD.

On linux we keep getting pci error 32993 in centOS_6.5_final,

I tried disabling pci slots 6-7 and got it to boot a couple times but no luck now after several reboots,

Also, do you really need to run the fans at max? 

Hi,

We dont have an error during posting but during the OS bootup, 

Also, did u use both the 8-pin and 6-pin connectors? From my memory, and previous setups, given the expansion card has one 8pin we should only really require the one 8-pin. However, the poweredge 720 states to plug both the 8-pin and 6-pin in.

thanks again for the replies,

So you never had any issues with APEI 32993 during boot of centOS?

Anything else you did to the bios? 

Were updating the bios now and will do a fresh install of centOS, 

Originally, we installed the K10 after CentOS was installed.

Hi ACCELEWARE ,

I do see exactly that error message. I have one K1 and one K2 plug in and in ESX only the K1 is visible.

Of course, I can simply disable the warning but what is the reason for this error? How to fix it?

Thanks
