I am currently having difficulties with ESXi 5.5, in passing a video card on to a Windows 7 install.
Components of Note:
Motherboard - http://www.newegg.com/Product/Product.aspx?Item=N82E16813157409
Processor - Xeon e3-1245v3 http://www.newegg.com/Product/Product.aspx?Item=N82E16819116909
RAM - 4x8GB for 32Gb total
Intel 520 180GB SSD for Datastore
ATI Radeon 6450 Graphics Card
I have installed Windows 7 64 bit, passed on a USB controller, where I have a working mouse/keyboard setup. Installed all windows updates, then rebooted and enabled the Radeon 6450 passthrough. It seems to pass through okay, I install drivers, but the system does not recognize any monitor plugged in to the graphics card. It appears to continue to only use the virtualized display adapter.
Also, I can not get the system to boot with any more than 2 gigs of RAM when the video card is passed through.
I have also tried passing through the integrated video chip on the Haswell processor/board, but I get the same results.
If I install VMware tools with the video card passed through, I get a BSOD.
Any ideas? Below is a pic of my passthrough options from this hardware combo.
