I have a running system with GA-H55-USB3 Mainboard and a i7-870 CPU.
The system is running W2008R2 with Hyper-V-Role enabled.
Due to l,ack of expansion slots, the existing ATI graphic card was removed, the dirvers uninstalled and the CPU changed to a i5-680.
The system works with integrated graphics, starts up now shows the grapbhic card as "Standard VGA-card"
Drivers for W2008 seem not to be available, Win7-drivers did not install
This is not the real problem, as the server does not really need high-performance graphic.
The main problem is now, that the system suddenly resets about every 2 hours or so, whic is as desaster.
SOmewhere else I found a posting that there is an issue with i5 CPus, integrated graphic and Hyper-V on W2008R2 - but this sohould be fixed with SP1. Of course my system has all available fixes installed.
What can I do ? In the meantime, I had to re-install the older i7 CPU
I would first suggest making sure that your motherboard supports Microsoft* Windows* 2008 operating system, if the motherboard does not support it you will have unexpected behaviors.
According to the following website, it seems the motherboard does not support it:
If the motherboard does not support it, then Hyper-V is not supported either since this is an operating system feature.
If you need to use a server operating system, I strongly suggest using a server motherboard, and not a desktop motherboard.
