Windows Vista 4 gig ram not showing in Vista home premium?

So I just installed it on my home PC (specs below) first thing I notice, its not showing my my full 4gb ram in the computer specs..is there a way to make it see this or do I need to get the 64 bit edition of Vista..which is..the ultimate version?

thanks

thanks Steve, I cant remember the exact number but it was 2. something I just installed it while I was sleepin..then had to come into work.
I really wanted to get the full use of my Ram if its possible, but yea I dont know if I wanna fork over another $400 for the 64 bit either..if thats my only option.

 

I'm at a bit of a loss here..... When it came out, I bought Vista Ultimate Upgrade, for an exorbitant amount of money, or so I thought - 259.00 US. The box it came in, took a while to figure out how to open, but it had 2 DVDs inside - 32 & 64 bit versions. I have seen numerous posts on a lot of boards about people considering 'buying' the 64 bit version after buying/installing another version.

Did I get something that others didn't get, or whats the deal.....

BTW, if you have Home, I believe you can upgrade to Ultimate without buying the full version, just the upgrade - not gonna be cheap, but cheaper than 400.00!!

 

The Ultimate edition comes with both x86 and x64 DVDs in the box, with all the other retail editions you only get the x86 DVD in the box, but you can send off for the x64 DVD for the cost of postage & packing. With OEM discs you have to specify which version you want up front, so if you buy x86 and want to move to x64 you would have to buy a new OEM disc.

 

thanks for that info.
It kinda sucked when I ordered the computer Dell did'nt offer the 64 bit version and I did'nt realise its needed to see all that Ram I have.

 

Excellent info. I checked it last night and it reports 2.5 gig of Ram..I guess those dual graphics cards eat it right up.
