I am about to upgrade my xp pro 32 bit to vista 64. I have 4 GB right now with Q 6600. I am all set, but i am undecided whether i should start vista with 2 GB or 4 GB during installation. I have heard that vista gives errors during installation with 4 GB of memory. I do not want to screw up my installation. On the other hand, i do not want to experience slow installation with 2 GB.
I did my install with my Q6600 and 8GB of ram. Took all of 10 minutes. No issues at all. You will love Vista 64, well maybe not love, still awesome though. All else fails if you have problems take out 2GB. Put it back in when your done. Also you do know that its a total format and reinstall right? I didnt know that when i got my 64bit. Took 3 hours to back up stuff to a spare drive lol.
To be on the safe side, install with 2GB. I doubt it will be much slower than with 4GB in. I went balls to the wall and did it with 8GB on a Q6600, didint even realize it might be a problem. I didn't have any issues though.
I have another question. I want to upgrade xp 32 bit pro to vista 64 bit ultimate edition. It is not a clean install. It is an upgrade, but i do not have an upgrade copy.Is it possible.
The last I heard, it was possible, but not advisable. You loose any data that was originally on the hard disk and the potential for problems can make it a nightmare that just isn't worth it.
As to the question of ram, when I did my build a few weeks ago using Vista 64 with SP1, I did the install with one 2 gig stick and then installed the second 2 gig stick. I ran through all the overclocking in the BIOS and got a nice stable run of about 4200mhz with 4 gig of ram. I then added another two sticks for 8 gig total and everything has remained stable, but the temps were higher than I'd like, so I backed off to 3825mhz to keep the loaded temp under 50c.
^Backup indeed ...
vista64 + 8gig = no problems at all ...
My Vista 64 ult. full "UPGRADE" installed initially with 4gb DDR400 on A8N32SLi deluxe MB, this was the non-OEM upgrade version , so I can upgrade next year again without probs.
Upgraded MB AM2+/CPU=7750 BE/DDR2RAM , w/o a fresh re-install of Vista 64 -worked fine, even added 4gb = 8gb - flew. Very fast and snappy and fun to use. A joy ove XP. BUT no WEI index available...
Re-installed Vista 64, w/o formatting, nor re-install XP, to a separate, existing partition. Worked for a while...
Then probles this w/e. crash. after burning DVD with DVD shrink = errors.
NOW, I re-installed "again" a true FRESH XP to SP3 etc.. OC'd 7750 BE, with 8Gb no worries at all - GREAT. installed photoshop, etc... just fine. Shows 3.25GB memory. Excellent. Foxconn A7DA-S bios all good = 8gb.
Cannot boot into VISTA to re-install or fix/repair from vista 64 upgrade DVD. Stalls after vista load bar - blank/black screen with waiting....or blue/green Vista OS install background, w/ mouse active. Waiting...waiting... nothing.
I may remove 2x 2gb sticks and try again ? I don't see why it shouldn't work ?
