I may hold of on buying Vista 64 bit , I need this to address my 4 gigs of ram

Vista 64 has no issue seeing 4 gigs of ram. Rather its more of an issue with the bios and hardware and saying it can support 8 gigs of ram is not always a guarantee that it will see that at the bios level, Even with the bios updates in place for just that issue.
With mine I found that it needed an increase of voltage to the ram sticks to see and use them.
The Service pack is irrelevant to it.
