Ok I just built a new PC for my fiancee.
Intel E6300 (1.86ghz)
Intel DG33TL Motherboard
Adata 4gb PC6400 2x2gb (4gb)
Hitachi Deskstar 80gb Sata 150
Vista Home Premium 64bit
Antec 900 case w/ Antec 380watt Earthwatts
I have loaded Vista 32 and 64bit before and above average(imo) in my PC build knowledge.
So I loaded Vista Home Premium 64bit on this system on Friday. Noticed the system booted very slow. Much slower then my Vista 32bit Media center and other Vista loads that I have done. The slow down is during the Vista boot screen. It takes FOREVER 3-4mins. (not actually timed) I did load all current intel drivers and made sure I defragged the drive after all was done. Still super slow boot. WHen I ran the Vista performance scan it came back with a 5.5 score for the Hard drive. While in the system it runs very good and no signs of poor hard drive performance.
So I reload my new system tonight since I figured maybe there was an old install of a OS on the drive. So I quick format 3x and deleted main partition and recreated it. Install the same Vista 64 OS and right after install is done I shut down and boot up. AGAIN the issue is there. SUPER slow boot times.
So next I have a NIB Seagate 320gb 16mb Sata 2 drive that I figured I would test in this system. Same install, same results. Super slow boot.
Next I start thinking MB,CPU or RAM. So the easiest is the RAM. I pull out one of the 2gb sticks and boot up. BAME! The Vista boot screen that usually takes a few minutes is on screen maybe 10secs tops before I see my mouse cursor. Wow I figure my RAM stick could be bad. So I test it again by shutting down without changing anything. BAME it boots up nice and fast again. So I put the 2gb stick back into the system and SUPER slow boot again.
So now I test the 2nd stick by it's self in slot 1 and it runs fine. I put the other stick back into the system and now the two sticks were swapped in position (slot 1 and 3) and SUPER slow boot comes back.
So I know each stick by it's self boots up quick. If I add both sticks to the blue color slot then the system will take a long time to boot. I just tried one more thing. Instead of running the sticks in the blue slots , I ran 1 in blue and 1 in black which I know is not ideal but just to check. Same slow boot with all 4gbs of ram. It did give me a performance warning for not running them both in the right slots. So next I run them both only in the black slots with the same slow boot issue.
What would cause this? I was thinking maybe the prefetch feature in Vista. Maybe with 4gb of RAM the system is loading so much into prefetch but with 2gb it doesn't bother with all the extra loading. I really doubt it and don't think prefetch really would work that way in regards to performance but I am all out of ideas on this. Hope I didn't confuse anyone.
2gbs of ram in this system boots great. 4gb no matter how you test it boots slow. Why?
*EDIT* - Just updated the BIOS and still have slow boot with 4gb.
