New graphics card GRID K1 not detected by BIOS when installed. Broken?
The setting to disable Embeded Video Controller is grayed out, indicating no extra GPU is detected.
In VMware no card is found, drivers will not load due to missing NIVIDA card.
Risercard slot is tested with another simple graphics card, works perfect.
GPU Installation kit power cable is connected from risercard socket to GPU.
Memory Mapped I/O above 4GB is Disabled.
No errors in iDRAC log. No errors during POST.
Dell support indicates that redundant 1100 W power supplies is needed. Is that really necessary to detect the card? We have two 900 W now.
Current powerusage 170W.
Dell PowerEdge R720
CPU 2 x Intel Xeon E5-2680 v2
BIOS version 2.5.2
Next step is to test the K1 in another R720 server. No high hopes for that to work…
What could be wrong except the graphics card? Please help.
