Basically, I want to upgrade my PC ram to 4 GB, so which version of Win7PE (x86 or x64) will allow me to use my complete ram. I had heard that almost all 32 bit OS cannot use more than 3 gb of ram... so will that limitation exist in Windows PE's ?
Secondly, I had been using Win7PE 32bit with ease, so if the 4 gb limitation exist can i use any software (as if Im Disk RamDisk or any other) to utilize my full ram.
