The reason for 12 GB is I Work from Home and I need to Build Virtual machines to Reproduce problems at Customers site...
I have build my system As follows:
Dual boot
XP 64 Bit Windows 2008 DataCenter R2 and Using HyperV and Or VMware Client 6.5
I have Build the VM's for SUSE 10, Windows 2003, XPpro, Vista, and Window7.
The problem is I need to Run the Database (Suse 10 or Windows 2003) and then the Client (XP,Vista) and the Application Server (Suse 10) and the same time
On the CPU side this is not an Issue as I can assign 1 of 2 Cores as required...
However with Memory I use 4 GB for the Host and 2-4 GB for the Database and 1-4 GB for the clients / Application server
The set up Currently: I have a ASUS PT6 Deluxe rev 1.x and Can not get it stable over 6 GB using a matched set of OCZ PC3 15000 OCZ3RPR1866C9LV6GK's (Shipped from OCZ Taiwan)
Runing @ 1066 @1333 @1600 or @ 1866 Talking to ASUS is like pissing in the wind
OCZ support is Great...
But ASUS..... well they only say that memory is not on our list we do not support it.
