Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
So started looking more at specs and since Standard Server 2008 is only limited to 32GB, I assume even with Hyper-V role added you can only have only 32GB total on the system.
Yes, however; you can install the standalone Hyper-V server - Microsoft® Hyper-V™ Server 2008 R2. The downside is there is no gui, but you don't have the memory limitation. You can manage it from one of your other systems and join it to your domain.
Another interesting option is to use Windows 8 Professional's Hyper-V. I am unsure if they are changed since the preview versions, but I've loaded them on Dell R720's with 96GB memory. That and Hyper-V v3 > Hyper-V v2.
