System:
Motherboard: Gigabyte GA-Z97P-D3 rev 1.0
BIOS Version: F9b (03/03/2016)
CPU: Intel i5-4460 (Haswell)
RAM: 32GB DDR3 1600MHz Corsair Vengeance (4x8GB)
GPU: NVIDIA Tesla P40 24GB
PSU: Corsair TX650M
OS: Ubuntu Linux (on separate drive, boots fine without P40)
What I've tried:
CSM disabled (Never)
Boot Mode set to Windows 8
Initial Display Output set to IGFX
setup_var 0x3 0x1 via modGRUBShell — confirmed set successfully
UEFIPatch applied with patches.txt + BdwUSB3.txt — flashed via Q-Flash, confirmed successful
Reverted to original unpatched BIOS F9b
CMOS battery removed for 60 seconds
Tested in both PCIe x16 slots
Tested with single RAM stick
PCIe slot set to Gen2 and Gen3
Symptom:
Continuous rapid beeping (~15 beeps) immediately on power on when P40 is installed. No POST, no display output. Board POSTs perfectly without P40 installed.
Behaviour is identical with both original and UEFIPatch patched BIOS — the patch made no difference to POST behaviour.
Notes:
Saw issue #63 which is the same board and BIOS — that user got drivers working but their system did POST with P40. My system won't POST at all.
The beeping is Gigabyte's continuous short beep code which their documentation says indicates PSU failure, however the board works fine without P40 and PSU passes paperclip test.
Linux boots and works correctly without P40. All kernel parameters already set: pci=realloc=on pci=nocrs amd_iommu=off
Additional notes:
P40 was previously tested in a different motherboard (ASUS M4A89GTD Pro, 890GX chipset, legacy AMI BIOS). It was detected by Linux (lspci showed Tesla P40), nvidia driver loaded successfully, /dev/nvidia0 device node created, but GPU UUID and Video BIOS showed as ??????????? indicating the BAR memory access was failing — consistent with no Above 4G Decoding support on that platform.
This confirms the P40 is working hardware — it was seen and partially initialised by the driver, just couldn't complete initialisation without proper 64-bit BAR support.
Current problem is earlier in the boot process — the GA-Z97P-D3 won't even POST with P40 installed, so I haven't reached the driver stage yet on this board.
Question:
Is there a known fix for GA-Z97P-D3 specifically to get past the POST beeping with Tesla P40? Is there a BIOS setting, VBIOS modification, or other approach that addresses the POST failure rather than the driver/OS level issues?
Thank you.
