INTEL DX79TO & DX79SI - GEFORCE GTX 670 INCOMPATIBILITY - ERROR 51, ALSO 1600 MEMORY UNDERCLOCKS AT 1066
From what we have tested in the workshop, we are unable to get an Intel mainboard DX79TO or DX79SI to work with a EVGA GTX 670 video card.
(The same VGA cards works with older Intel boards)
It looks like an incompatibility of some sort - with all the boards we tested reporting "error 51" on the board display accompanied by 2 beep, pause, 2 beeps and then continues to boot into windows and function normally. It must be noted that there is no display or otherwise until PC has booted into windows.
(Notes: Boards have been updated to latest bios', 1000w and 700w PSU tested. Also GTX 260 & 560 cards works with all configurations)

Hello Lyle,
We appreciate your feedback on this matter.We also would like to inform you that our products are built to industry standards but there is still the possibility of incompatibility. Power supplies are sufficient since different models are working fine.

Hi,
Perhaps this NVIDIA posted article will be helpful. http://nvidia.custhelp.com/app/answers/detail/a_id/3156/session/L3RpbWUvMTM1NjgwMDAwNi9zaWQvZjl6Mnha... When installing an after-market graphics card into a certified Windows 8 PC with UEFI enabled, the system may not boot.

Hi,
Have replaced EVGA 670 with ASUS 670 and bios is now visible (PS. PC was still able to boot into windows, bios/ POST had no display with "Error 51")
However, I have picked up another problem with the DX79TO series.
Unable to set memory to 1600, memory only works under clocked at 1066.
Configuration:
Intel DX79TO or DX79SI mainboard
Intel i7 3820, 3.6Ghz
Corsair Dominator 2 X 4GB DDR-1600 (CMP8GX3M2A1600C9)
ASUS GTX 670 2GB
Cooler master 1000W PSU
Kind Regards

The link given by dave_g is the answer, but in reverse: new EVGA GTX 600 series cards have UEFI GOP-compatible BIOS, the DX79 boards BIOS do not support SecureBoot and GOP instead. So wait until Intel bring SecureBoot support for DX79 BIOS, until that use cards from other vendors.
