ESXi 5.5, Passthrough Video Card, Haswell Build

[NotYetRated]

I am currently having difficulties with ESXi 5.5, in passing a video card on to a Windows 7 install.

Components of Note:

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.

Hello guys,

I'm using now ESXi 6.5 and I'm trying to passthrough Radeon R9 380.

I'm having same issue as most of the users on this thread described - not getting picture on the integrated GPU at all.

After I install the catalyst driver and I reboot I got BSOD and after the next reboot I see windows loads, but instead of login screen I see only a black blank console.
No video on the physical GPU and black screen on the vmware console.

My question here is:
Everyone says "Disable the onboard GPU" but no one says how do you get your ESXi host running.
Since it's x86 system it needs at least one GPU for the host operating system. If you disable the onboard GPU then you need to have 2 other GPUs - 1 for the host and 1 for the passthrough?

Am I getting this one correct?
1. disable the onboard GPU

2. boot ESXi host with one PCI-E GPU (have it selected as primary GPU in BIOS)
2. have second GPU on PCI-E that will be used for passthrough
