I currently have 4gb RAM on my PC. Although I have a 32 bit OS, it can see 3.3gb. I now have VMs and this can cause performance issues as there is competition for resources.
I am not sure if I can buy memory which is 2gb per slot (2 x 4 = 8gb). When buying memory, what dictates compatibility (pins is one of those things I believe)?
In the case that I cannot use more memory than this, what other methods can I use to solve memory issues? I have seen software which allows you to use your USB pen as RAM (not ReadyBoost in Vista, a MS Gold Partner made some software for this but I don't know how good it is let alone the company name anymore). Would this be effective? I have slots for two HDs in my PC and both are taken. SSD as RAM is not effective due to slow write speed (or is that read?).
