Rocky RR Posted July 17, 2007 Share Posted July 17, 2007 My motherboard has 4 slots for memory boards. I now have a total of 2 GB's (1 GB in each of 2 slots, leaving 2 vacant slots). It's my understanding that my 32 bit system (I have an Intel mother board and my OS is Vista Business) can not support 4 GB's. Can I add just one more 1 GB board in one of the remaining slots? What would happen if I added 2 GB's in the remaining 2 slots? Link to comment Share on other sites More sharing options...
iCEhOT Posted July 17, 2007 Share Posted July 17, 2007 You can have up to 4Gb on a 32bit system, however the issue arrises when you do put 4Gb on a 32bit system in that other resources also make use of the address space, and you have no control over this. So what tends to happen is you end up with about 3.2Gb of usable memory or there abouts, so you still have more than you would from just 3Gb (most of the time).If I were you I'd do what I did with mine, and had 2 sticks of 1Gb paired up and 2 sticks of 512mb paired up, that way you pretty much get all the memory you've paid for and it's still more than most home users currently need.

fizban2 Posted July 17, 2007 Share Posted July 17, 2007 another thing to think about is if you are willing to go to 64x bit Vista, if that is the case having 4 gig would not be a bad idea, granted in 32 bit you will probably see 3.5 at the best, but getting 4 gig will leave you better prepared to move to a 64 bit OS. plus the price difference can't be that great anymore Link to comment Share on other sites More sharing options...
Rocky RR Posted July 17, 2007 Author Share Posted July 17, 2007 Fizban2, can I upgrade to the 64 bit Vista without having to reinstall all my software, etc.? Also, would I just buy a 64 upgrade of Vista Business?Thanks Link to comment Share on other sites More sharing options...
fizban2 Posted July 18, 2007 Share Posted July 18, 2007 would have to buy the 64 bit upgrade, but you would end up having to do a clean install as there is no upgrade path from x86 to 64 bit Link to comment Share on other sites More sharing options...
tommaso Posted July 18, 2007 Share Posted July 18, 2007 Sorry if I stuck in this post but... As far as I run a x64 Vista (2 Gb RAM @ 800Mhz) and I noticed that Vista tend to use something like 30-35% of my RAM all the times, is it a good idea to upgrade to 3 or 4 Gb?TK you Link to comment Share on other sites More sharing options...
