HP Z820: Nvidia GT710 (does not require PCIe power) is not recogized during boot. I get 6 beeps

HP Recommended
HP 820

as above.

  • according to this HP support page (click here), 6 beeps is a video card error
  • according to this HP service advisory (click here), 6 beeps is also a video card issue but can be fixed by clearing CMOS
  • I don't have the original Nvidia K4000 to try but it booted fine (all the way to Ubuntu live USB desktop) when I doing the pre-sale test/inspection.
  • The GT710 works fine in another PC (via HDMI).
  • I've cleared the CMOS (pressing the button for 20 seconds while the PC is off but plugged in). I did this step twice.
  • I tried  multiple PCIe (colored black and see the see image below)

Any other ideas?




Edit1: I originally inserted the image on the post but it's not showing up. I decided to upload it somewhere else instead.

your 710 is a extremely slow card that only is useful at 640x480 or 1200x788 as such i highly recommend you select a card that is going to be able to do more than display the desktop in low resolution


i recommend you reset the bios back to "factory" defaults rather than just the predefined defaults


to fo a factory bios reset remove the power cord from the system and then press the power button for 15 sec, now remove the cmos battery and then press the cmos reset button for more than 3 sec


replace battery, connect power and start system and set time/date system is now at factory bios settings with Legacy (CMS) and UEFI enabled


never ever enable the "compute" option for any pcie/pci slots, doing so turns off video functions on that slot and if all slots are set to compute then the board is bricked and needs to be replaced


if you don't need to boot from the onboard LSI SAS/SATA controller disable the LSI BIOS (not the lsi device!)


same for boot from network, if not used disable this option in the bios, doing these steps will make the system boot much faster
