I try add VGA Card GeForce210 1G or ATI HD4650 512M GDDR3 on S1200BTS, but PCIe x16 used as a x8 link on this board can't detect the VGA card?
The manual says, if processor used ivy bridge series, the PCI-E x16 change to Gen3. this is problem?
E3-1220v2, 2x2G DDR ECC.
Used many VGA cards on this board and all work (as x8). You tried to disable VGA onboard (in BIOS) ? Tried to play with maximize memory below 4GB and other settings around this BIOS setting?
Thanks Blitz for the reply before.
My O/S is Win XP Pro, maybe this the problem.
On Device manager i found (?) string on Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port - 0151. This symptom like thread
When you tried to disable VGA onboard, the signal to monitor is gone, completely disable (see manual):
126.96.36.199 Dual Video
The BIOS supports both single-video and dual-video modes. The dual-video mode is disabled
* In the single mode (dual monitor video = disabled), the on-board video controller is
disabled when an add-in video card is detected.
* In single mode, the onboard video controller is disabled when an add-in video card
is detected. Warning: System video is completely disabled if this option is disabled and an add-in video
adapter is not installed.
* In dual mode, the onboard video controller is enabled and is the primary video device.
The external video card is allocated resources and is considered the secondary video device.
thats why I'm just enable/disable dual display on BIOS. I will try enable Maximize Memory below 4G.
To make sure - you are using S1200BTSR (latest PBAs) right ? Original S1200BTS does not support IvB (means you have PBA E98683-352 or higher, BIOS revision 35 or later)
I'm used PBAs E98683-352 and BIOS already upgraded to revision 40.
VGA on board is normal.
The problem is, the secondary VGA on PCIe is not detect. I was tried with 2 VGA different. (ATI and Nvidia).
