Fixed my sleep/wake issue!Did you find a fix for the wake issue? I have the same problem. Everything else works great.
I hope this helps others that are having sleep issues after adding a video card. I have been trying for about 2-3 weeks now. Yesterday I was playing with overclocking and caused my system to not post. I had to clear the bios to get it back up. After I cleared the bios I made the following adjustments per guides I have read:
Load Optimized Defaults
MIT / Extreme Memory Profile (X.M.P.) = Profile1
BIOS Features / Intel Virtualization Technology = Disabled
BIOS Features /VT-D = Disabled
Peripherals / SATA Mode Selection = AHCI
Peripherals / xHCI Hand-off = Enabled
Peripherals / EHCI Hand-off = Enabled
Since my sleep trouble started after adding the GT 640 I decided to snoop and make some changes.
I made sure that
Init Display First = Auto
Internal Graphics = DISABLED
Saved and exit.
Now sleep/wake works great. So if you are having sleep/wake issues with graphics card installed try disabling internal graphics in bios.
Maybe it was the clearing of the Bios, but I think the internal graphics=disabled is what really fixed it. YMMV. I hope this helps someone else.
I will try on my i3 hackintosh when I get home. Same mobo and graphics suffering from no wake from sleep. If this works on that system I will be certain.
