[QUOTE="IvanLasston, post: 1195512, member: 145676"] You will be able to use all 8GB of RAM. Programs may not be able to use all 8 at one time. Do you have programs that need more than 4GB of RAM? Let me be clear DO NOT BOOT INTO 64 BIT MODE UNLESS YOU HAVE A SPECIFIC PROGRAM OR DATA THAT REQUIRES MORE THAN 4GB OF RAM. (Yes there are always exceptions but most people figure 64 is more than 32 so it must be better) I have 8GB of RAM - run in 32bit mode and have seen no problems. Playing HD files, messing with 12Mbit Photos in Photoshop, editing 10-20 minute HD movies in Adobe Premiere, everything runs fine without going into 64 bit mode. Anyway - try 32 bit mode and try the VPN.
